Your First In-Game Telemetry Event - A Beginner-First Privacy-Safe PostHog Pipeline for Unity and Godot Indie Games (2026)

You're a 1-3 person indie team. Your game has launched (or is about to), and you're staring at a vital question: does anyone actually finish the tutorial? You don't know. You'd like to know. But "add analytics" sounds like a week of work and a privacy-policy lawyer call - so you keep pushing it off, and you keep shipping decisions on gut feel.

This guide ships a ninety-minute end-to-end pipeline that emits your first privacy-safe in-game telemetry event from Unity 6.6 LTS or Godot 4.5 into a PostHog dashboard, with zero personally identifiable information crossing the wire and full 2026 platform-privacy-rule compliance. The recipe is deliberately beginner-first: one event, one dashboard, one ninety-minute working evening. You'll know whether players finish the tutorial by tomorrow morning.

Why this matters now

Three concurrent 2026 pressures make the privacy-safe-telemetry discipline urgent right now:

  • Apple App Tracking Transparency tightened in early 2026 with refined enforcement of the "tracking" definition; small indie games using ad-network SDKs were retroactively reviewed and several were pulled from the App Store in Q1 2026 for non-disclosed tracking. First-party privacy-safe telemetry that does not cross the "tracking" threshold is now the indie-safe default; ATT prompts are no longer worth the conversion-loss cost for most non-monetized indie titles.
  • Google Play Developer Programme Privacy revisions landed late 2025 and continued through early 2026 with the Data Safety Section requiring explicit disclosure of all collected data plus its purpose. The 2024 indie habit of "we'll add analytics later and update Data Safety then" produces submission-time friction in 2026; the easier path is to start with privacy-safe telemetry and disclose only the minimal data category from launch.
  • EU GDPR + DMA second-wave audits Q3 2026 will retroactively review compliance of titles distributed to EU users. Indie teams who shipped third-party tracking SDKs without a cookie banner or opt-in flow are exposed to backdated enforcement; teams using self-hosted or first-party privacy-safe telemetry have a much shorter audit surface.

The 2024 default of "drop a Unity Analytics or Firebase Analytics SDK and add a one-line privacy policy" is no longer the indie-safe default in 2026. The 2026 indie-safe default is first-party telemetry that does not collect PII, is documented in a one-page privacy posture statement, and is opt-in or anonymous-by-design.

PostHog (self-hosted or cloud) has emerged as the indie-friendly choice for this in 2026 because it supports anonymous event tracking, has a generous free tier on cloud (1M events/month), and lets you self-host on a €5/month VPS for zero per-event cost. The recipe below targets PostHog specifically, but the principles apply to Plausible Analytics (for events emitted via their script), self-hosted Matomo, or rolling your own SQLite + Cloudflare Worker endpoint.

Direct answer (TL;DR)

For a 1-3 person indie team in 2026, the defensible first-telemetry-event posture is:

  1. Pick PostHog Cloud free tier as the starting point; switch to self-hosted PostHog on a €5/month VPS once you exceed 1M events/month (you will not exceed this for at least your first year).
  2. Emit one event: tutorial_step_completed with two properties (step number, time-since-tutorial-start in seconds). No player name, no email, no IP retention, no device fingerprint. Anonymous distinct ID generated per-install via Guid.NewGuid() (Unity) or crypto.crypto_strong_random_value() (Godot) and stored locally.
  3. Wire the event from Unity via Posthog.Unity package (community-maintained, MIT-licensed; install via package.json git URL) or via plain UnityWebRequest.Post to PostHog's /capture endpoint with a tiny TelemetryClient.cs (recipe below).
  4. Wire the event from Godot 4.5 via plain HTTPRequest node calling PostHog's /capture endpoint with a small telemetry.gd autoload (recipe below). No third-party package required.
  5. Document the privacy posture in a one-page release-evidence/privacy.md: what's collected, what's not collected, retention period, how to opt out. Link it from your in-game About menu and your Steam / Play Store / App Store privacy policy field.
  6. Build a one-chart dashboard in PostHog: "% of users who fire tutorial_step_completed for the final step within 30 minutes of first launch." That single number is the most actionable indie metric you can collect.

The rest of this piece walks through the wire-up step by step for both engines, the six recommended starter events (only one of which is tutorial_step_completed), three opt-in patterns that satisfy 2026 platform privacy rules, and the eight common mistakes that bite beginner-first indie teams.

Who this is for

This article is written specifically for:

  • 1-3 person indie teams who have never shipped analytics in a game and are intimidated by the setup cost
  • Teams shipping on Steam, itch.io, Google Play, App Store, Quest Store in 2026 where the privacy compliance bar materially rose
  • Teams using Unity 6.6 LTS or Godot 4.5 (other engines: the principles apply; the code samples need adapting)
  • Teams that have at least one launched game (or near-launch demo) where understanding player behavior would change next-week decisions
  • Anyone who's been quietly putting off "add analytics" for six months because it felt like a lawyer-and-engineering week

If you have an existing Firebase Analytics or Unity Analytics integration you're happy with, this piece is still useful as a 2026 privacy-posture check - skim the failure modes and the three opt-in patterns and see whether your current setup is exposed under the 2026 audit framework.

Beginner Quick Start - The Ninety-Minute Path

Before the long explanation, here's the ninety-minute path so you can start. Define unfamiliar terms in plain language as we go.

Step 1 (10 min): Create a PostHog Cloud free account

  • Go to posthog.com, sign up, pick the EU region if your players are EU-located (matches GDPR posture cleanest), otherwise pick the US region.
  • Create a new project; copy the Project API Key (a string starting with phc_).
  • Success check: you see an empty PostHog dashboard with the message "Waiting for first event."

PostHog is a product-analytics platform. Self-hosted or cloud. Free tier 1M events/month. We use it because it supports anonymous event tracking without cookies or device fingerprinting.

Step 2 (15 min): Decide your first event

For your first event, pick one of:

  • tutorial_step_completed (with step number) - recommended; highest information value per event
  • level_completed (with level number)
  • menu_opened (with menu name) - good if your tutorial is non-linear

A telemetry event is a small JSON message your game sends to your analytics backend when something interesting happens. Think of it as a labeled tally mark: "one more player just finished tutorial step 3."

Success check: you can write your event name and two properties on a sticky note in 30 seconds.

Step 3 (30 min): Wire the event

Unity: skip to "Recipe A - Unity 6.6 LTS Wire-Up" below.

Godot: skip to "Recipe B - Godot 4.5 Wire-Up" below.

Success check: you trigger the event in your game (run the game, complete a tutorial step) and the event appears in PostHog's Live Events view within 30 seconds.

Step 4 (20 min): Build the one-chart dashboard

In PostHog:

  • Click Insights > New insight > Funnel.
  • Step 1: tutorial_step_completed with property step = 1.
  • Step 2: tutorial_step_completed with property step = N (where N is your final tutorial step).
  • Time window: 30 minutes.
  • Save the insight as "Tutorial completion within 30 min."
  • Pin the insight to a new dashboard called "Indie game weekly review."

Success check: the dashboard shows a funnel with conversion rate. (It will be empty until players generate events.)

Step 5 (15 min): Write the one-page privacy posture statement

Create release-evidence/privacy.md:

# Privacy Posture - <Your Game Name> (2026)

## What we collect
- Anonymous game-event telemetry (event names like `tutorial_step_completed` plus minimal event properties such as step number, time since tutorial start).
- An anonymous distinct ID generated per install on first launch (random UUID). Not linked to any account, email, or device identifier.

## What we DO NOT collect
- Player name, email, IP address (PostHog discards it; we set `$ip: null`), device fingerprint, advertising ID, location, contact list, photos, microphone, camera, or any other PII as defined by GDPR Article 4.

## Retention
- Events are retained for 90 days then deleted.

## Opt out
- Toggle "Help improve the game (anonymous analytics)" OFF in Settings > Privacy. The toggle defaults to OFF in the EU and ON elsewhere (configurable to default OFF globally if you prefer).

## Where it goes
- PostHog (posthog.com) - EU region for EU players, US region otherwise. PostHog is GDPR-compliant by configuration; we use their anonymous event tracking mode.

## Contact
- Privacy questions: <your contact email>.

Success check: the privacy posture fits on one page, uses plain English, and you can hand it to a non-technical friend who can summarize it back in 30 seconds.

That's it. Ninety minutes total. The recipes below cover Step 3 in detail; everything else is checklist-pace.

Recipe A - Unity 6.6 LTS Wire-Up

Two paths: the lightweight one (zero-dependency UnityWebRequest) or the community-package path (posthog-unity). For first-event work, the lightweight path is better - no dependency to vet, no SDK surface to learn, full control over what crosses the wire.

A.1 Create Assets/Scripts/Telemetry/TelemetryClient.cs

using System;
using System.Collections;
using System.Collections.Generic;
using System.Text;
using UnityEngine;
using UnityEngine.Networking;

public class TelemetryClient : MonoBehaviour
{
    private const string POSTHOG_HOST = "https://eu.i.posthog.com";  // or us.i.posthog.com
    private const string PROJECT_API_KEY = "phc_REPLACE_WITH_YOUR_KEY";

    private string _distinctId;
    private bool _enabled;

    private void Awake()
    {
        DontDestroyOnLoad(gameObject);
        _distinctId = LoadOrCreateDistinctId();
        _enabled = PlayerPrefs.GetInt("telemetry_opt_in", DefaultOptIn()) == 1;
    }

    public void Capture(string eventName, Dictionary<string, object> properties = null)
    {
        if (!_enabled) return;
        StartCoroutine(SendCapture(eventName, properties));
    }

    private IEnumerator SendCapture(string eventName, Dictionary<string, object> properties)
    {
        var payload = new Dictionary<string, object>
        {
            ["api_key"] = PROJECT_API_KEY,
            ["event"] = eventName,
            ["distinct_id"] = _distinctId,
            ["properties"] = properties ?? new Dictionary<string, object>(),
            ["timestamp"] = DateTime.UtcNow.ToString("o"),
        };
        var props = (Dictionary<string, object>)payload["properties"];
        props["$ip"] = null;
        props["$lib"] = "indie-unity-2026";
        props["game_version"] = Application.version;

        var json = JsonConvert.SerializeObject(payload);
        var body = Encoding.UTF8.GetBytes(json);

        using (var req = new UnityWebRequest($"{POSTHOG_HOST}/capture/", "POST"))
        {
            req.uploadHandler = new UploadHandlerRaw(body);
            req.downloadHandler = new DownloadHandlerBuffer();
            req.SetRequestHeader("Content-Type", "application/json");
            yield return req.SendWebRequest();
            if (req.result != UnityWebRequest.Result.Success)
            {
                Debug.LogWarning($"Telemetry send failed (non-fatal): {req.error}");
            }
        }
    }

    private string LoadOrCreateDistinctId()
    {
        var id = PlayerPrefs.GetString("telemetry_distinct_id", "");
        if (string.IsNullOrEmpty(id))
        {
            id = Guid.NewGuid().ToString();
            PlayerPrefs.SetString("telemetry_distinct_id", id);
            PlayerPrefs.Save();
        }
        return id;
    }

    private int DefaultOptIn()
    {
        // Default OFF in EU, ON elsewhere. Use your own region detection.
        // Conservative default for indie teams: OFF everywhere.
        return 0;
    }

    public void SetOptIn(bool optIn)
    {
        _enabled = optIn;
        PlayerPrefs.SetInt("telemetry_opt_in", optIn ? 1 : 0);
        PlayerPrefs.Save();
    }
}

Add JsonConvert via Unity's Newtonsoft.Json package (com.unity.nuget.newtonsoft-json in Package Manager - bundled with most Unity 6.x projects already).

A.2 Add to your scene

Create an empty GameObject called Telemetry, attach TelemetryClient. The DontDestroyOnLoad makes it survive scene transitions.

A.3 Trigger the event

In your tutorial flow:

public class TutorialStep : MonoBehaviour
{
    public int StepNumber;
    private float _stepStartTime;
    private float _tutorialStartTime;

    private void OnEnable()
    {
        _stepStartTime = Time.realtimeSinceStartup;
        if (StepNumber == 1)
            _tutorialStartTime = _stepStartTime;
    }

    public void OnStepCompleted()
    {
        var telemetry = FindObjectOfType<TelemetryClient>();
        telemetry?.Capture("tutorial_step_completed", new Dictionary<string, object>
        {
            { "step", StepNumber },
            { "seconds_since_tutorial_start", Time.realtimeSinceStartup - _tutorialStartTime }
        });
    }
}

Success check: run the game, complete a tutorial step, open PostHog's Live Events view; the event appears within 30 seconds.

Recipe B - Godot 4.5 Wire-Up

Godot has no official PostHog SDK, but the HTTP capture endpoint is dead simple - a 60-line autoload does the whole job.

B.1 Create telemetry/telemetry.gd

extends Node

const POSTHOG_HOST := "https://eu.i.posthog.com"
const PROJECT_API_KEY := "phc_REPLACE_WITH_YOUR_KEY"

var _distinct_id: String
var _enabled: bool
var _http: HTTPRequest

func _ready() -> void:
    _distinct_id = _load_or_create_distinct_id()
    _enabled = _load_opt_in()
    _http = HTTPRequest.new()
    add_child(_http)
    _http.request_completed.connect(_on_request_completed)

func capture(event_name: String, properties: Dictionary = {}) -> void:
    if not _enabled:
        return
    var props := properties.duplicate()
    props["$ip"] = null
    props["$lib"] = "indie-godot-2026"
    props["game_version"] = ProjectSettings.get_setting("application/config/version")
    var payload := {
        "api_key": PROJECT_API_KEY,
        "event": event_name,
        "distinct_id": _distinct_id,
        "properties": props,
        "timestamp": Time.get_datetime_string_from_system(true),
    }
    var headers := ["Content-Type: application/json"]
    var body := JSON.stringify(payload)
    _http.request("%s/capture/" % POSTHOG_HOST, headers, HTTPClient.METHOD_POST, body)

func _on_request_completed(result: int, code: int, _headers: PackedStringArray, _body: PackedByteArray) -> void:
    if result != HTTPRequest.RESULT_SUCCESS or code >= 300:
        push_warning("Telemetry send failed (non-fatal): result=%d code=%d" % [result, code])

func _load_or_create_distinct_id() -> String:
    var cfg := ConfigFile.new()
    cfg.load("user://telemetry.cfg")
    var id: String = cfg.get_value("telemetry", "distinct_id", "")
    if id == "":
        id = _new_uuid()
        cfg.set_value("telemetry", "distinct_id", id)
        cfg.save("user://telemetry.cfg")
    return id

func _load_opt_in() -> bool:
    var cfg := ConfigFile.new()
    cfg.load("user://telemetry.cfg")
    return cfg.get_value("telemetry", "opt_in", false)

func set_opt_in(opt_in: bool) -> void:
    _enabled = opt_in
    var cfg := ConfigFile.new()
    cfg.load("user://telemetry.cfg")
    cfg.set_value("telemetry", "opt_in", opt_in)
    cfg.save("user://telemetry.cfg")

func _new_uuid() -> String:
    var bytes := Crypto.new().generate_random_bytes(16)
    return "%02x%02x%02x%02x-%02x%02x-%02x%02x-%02x%02x-%02x%02x%02x%02x%02x%02x" % [
        bytes[0], bytes[1], bytes[2], bytes[3],
        bytes[4], bytes[5],
        bytes[6], bytes[7],
        bytes[8], bytes[9],
        bytes[10], bytes[11], bytes[12], bytes[13], bytes[14], bytes[15]
    ]

B.2 Register as autoload

Project Settings > Autoload > Add → path res://telemetry/telemetry.gd, name Telemetry. Now Telemetry.capture(...) works from anywhere in your project.

B.3 Trigger the event

In your tutorial node:

extends Node

@export var step_number: int = 1
var _tutorial_start_ms: int = 0

func _ready() -> void:
    if step_number == 1:
        _tutorial_start_ms = Time.get_ticks_msec()

func on_step_completed() -> void:
    var seconds := (Time.get_ticks_msec() - _tutorial_start_ms) / 1000.0
    Telemetry.capture("tutorial_step_completed", {
        "step": step_number,
        "seconds_since_tutorial_start": seconds
    })

Success check: run the game, complete a tutorial step, open PostHog's Live Events; the event appears within 30 seconds.

What "Privacy-Safe" Actually Means in 2026

A privacy-safe telemetry event has all of these properties:

  • No PII under GDPR Article 4 (no name, email, IP, device fingerprint, advertising ID, location, contact list, biometric data)
  • Anonymous distinct ID generated client-side, not linked to any account or platform identifier
  • No silent always-on collection without disclosure - the privacy posture page documents what's collected
  • Functional opt-out that actually stops events (not just hides a toggle while events keep flowing)
  • Bounded retention - events aged out after a documented window (90 days is the indie-friendly default)
  • No third-party sharing for advertising or profiling
  • Documented data flow the player can audit (one-page privacy posture)

The recipes above satisfy all seven properties by construction. If you change one (add player_name to the event, link distinct_id to a Steam account ID, retain forever), you've left the privacy-safe envelope and need to reconsider the 2026 platform-policy implications.

The Six Recommended Starter Events

Once your first event is firing, you can add five more over the next month. The full beginner set:

  1. tutorial_step_completed (properties: step, seconds_since_tutorial_start) - the first event; tells you tutorial conversion. Already wired in Recipe A or B above.
  2. level_completed (properties: level_id, completion_time_seconds, attempts) - tells you which levels are too hard or too long.
  3. menu_opened (properties: menu_name) - tells you which features players actually find vs which are buried.
  4. game_session_started (properties: session_number_for_user) - tells you retention (count distinct distinct_ids whose session_number = 7 / count distinct_ids whose session_number = 1).
  5. crash_or_error_recovered (properties: error_category) - high-cardinality categorical error tracking without PII; complements (does not replace) a real crash reporter.
  6. store_link_clicked (properties: link_destination, source_screen) - tells you if your in-game "Wishlist on Steam" button drives clicks.

That's a one-month roadmap. Six events. Each one adds a specific actionable insight. Resist the urge to add more in your first month; analysis paralysis from event firehose is real.

Three Opt-In Patterns That Satisfy 2026 Platform Privacy Rules

Pick one based on your audience and regulatory exposure. All three are 2026 platform-compliant.

Pattern 1 - Opt-out everywhere with a clear toggle (lightest)

  • Telemetry defaults ON.
  • Settings > Privacy has a clear "Help improve the game (anonymous analytics)" toggle, default ON.
  • Privacy posture documented in About menu and platform privacy field.
  • Risk profile: lowest-friction; most data. Acceptable in the US for non-EU-distributed games. Not GDPR-compliant for EU distribution - GDPR requires explicit opt-in for anything beyond strictly necessary processing.

Pattern 2 - Region-aware default (recommended for most indies)

  • Telemetry defaults OFF for EU players, ON elsewhere.
  • Region detection via VPN-resilient signal (player's selected language as a proxy + a one-time "Are you in the EU?" prompt on first run).
  • Settings toggle present everywhere.
  • Risk profile: GDPR-compliant for EU; ATT-compatible for iOS; reasonable data volume from non-EU players. The 2026 indie sweet spot.

Pattern 3 - Opt-in everywhere (most conservative)

  • Telemetry defaults OFF globally.
  • First-run prompt: "Help improve [game name] by sending anonymous play data? You can change this any time in Settings."
  • Privacy posture page link in the prompt.
  • Risk profile: GDPR-compliant; ATT-compatible; lowest data volume (typically 15-35% opt-in rate). Use this when in doubt or when your audience is privacy-sensitive (open-source player base, F-Droid distribution, EU-heavy player skew).

All three patterns use the same TelemetryClient.SetOptIn(true/false) API; only the default and the first-run UX differ. Switching between patterns is a single-line change.

Eight Common Mistakes Beginner-First Indie Teams Make in 2026 Telemetry

  1. Logging player name or email as an event property: never. Even if you have the data because of an in-game name input, you do not need it in your analytics backend; the distinct_id replaces it. Names are PII; the GDPR is unambiguous.

  2. Linking distinct_id to a Steam account ID, Quest ID, or Google Play games services ID: also PII when joined to platform data. Keep distinct_id strictly client-generated and locally stored.

  3. Forgetting to set $ip: null: PostHog (and most analytics backends) capture IP by default for geolocation. The recipes above explicitly null out $ip to prevent this. If you skip this step, you are silently collecting an IP per event.

  4. Sending events synchronously on the main thread: a blocked main thread on a slow connection produces a frame hitch on every event. Unity's UnityWebRequest in a coroutine is async; Godot's HTTPRequest node is async. The recipes above are async by construction.

  5. Not handling the offline-then-back-online case: if the player is offline, events are dropped in the recipes above. For your first telemetry event, this is acceptable. For your sixth, add a 10-event in-memory ring buffer that flushes on next online connection. Don't persist events to disk - that's where privacy-policy review gets thornier.

  6. Storing distinct_id in cleartext at a guessable filesystem path: the recipes above store at PlayerPrefs (Unity) or user://telemetry.cfg (Godot), which are standard, low-risk locations. If you put the distinct_id in your game's screenshots folder or a public asset path, you've created an exfiltration vector.

  7. Treating "anonymous" as "no privacy policy needed": 2026 platform stores require a privacy policy disclosure even for fully anonymous analytics. The Google Play Data Safety Section requires "App activity > In-app actions" disclosure if you collect any event data, regardless of anonymity. Always link your privacy posture page.

  8. Skipping the dashboard step: events without a dashboard are unread events. Build the one-chart funnel before you ship the event; otherwise the event becomes a "future me will look at this" debt item that never gets paid down.

Decision Tree - Pick Your Path

  • Q1: Are you EU-distributed (Steam, App Store, Play Store, itch.io with EU audience)? → If yes, use Pattern 2 (region-aware default) or Pattern 3 (opt-in everywhere). If no, Pattern 1 is acceptable but Pattern 2 is recommended for future-proofing.
  • Q2: Are you Unity-based or Godot-based? → Unity = Recipe A; Godot = Recipe B. (Other engines: principles apply, code samples need adapting.)
  • Q3: Have you launched yet, or are you pre-launch? → Pre-launch: ship the first event in your demo / playtest builds; you'll get real data months before launch. Post-launch: ship in the next patch; the event starts populating immediately.
  • Q4: Do you have an existing analytics SDK (Unity Analytics, Firebase, GameAnalytics)? → If yes, evaluate it against the 2026 privacy-safe envelope above; many SDKs collect more than you think. Adding PostHog alongside as a privacy-safe complement is fine.
  • Q5: Do you have a small studio or solo? → Solo: stick to PostHog Cloud free tier for at least the first year; you will not exceed 1M events/month. 3-person studio: same advice unless your game launches at 10K+ DAU, in which case self-host on a €5/month VPS for cost control.

Seven Pro Tips for Sustainable First-Telemetry-Event Discipline

  1. Pin the recipe and the privacy posture in your repo at release-evidence/privacy.md and release-evidence/telemetry-recipe.md. Every new contributor reads them on day one; every platform privacy field links to the privacy posture file's public URL.

  2. Wrap the first telemetry event's dashboard into Block 1 of the 30-minute Friday operating review. The metric: "tutorial completion within 30 min." A single number you check every Friday.

  3. Add the second event only after the first event has fired for two weeks. Discipline against over-eager event-firehose. If you add events faster than you analyze, you build technical debt.

  4. Test the opt-out path manually before shipping: toggle opt-out, fire 10 events, verify zero new events show up in PostHog. The most common 2026 audit-failure is "the opt-out toggle doesn't actually stop events."

  5. Document the dashboard URL in your README or wiki so a non-technical co-founder can check it without asking. Telemetry that requires a technical co-founder to interpret is half-dead.

  6. Pair the telemetry pipeline with the deterministic soft-lock replay hook: when telemetry shows a tutorial step is the conversion drop, the replay hook lets you reproduce one specific player's stuck state.

  7. Re-audit your privacy posture quarterly. Privacy rules tighten 2-3 times a year in 2026; what was compliant in Q1 may not be in Q4. The audit takes 30 minutes if you keep the posture page current.

Mapping to Other Site Resources

This first-telemetry-event piece sits inside an ecosystem of indie-data, privacy-posture, and live-ops posts we publish:

Key takeaways

  • 2026 platform-privacy rules (Apple ATT refinements, Google Play Data Safety, EU GDPR + DMA second-wave audits) make privacy-safe first-party telemetry the indie-safe default; the 2024 "drop a Firebase SDK" path is no longer the lowest-risk option.
  • Ship one event first: tutorial_step_completed with step number + seconds-since-tutorial-start. Zero PII. Anonymous distinct ID. Ninety minutes end-to-end.
  • PostHog Cloud free tier (1M events/month) is the recommended indie starting point; self-host on a €5/month VPS once you exceed (you will not exceed for at least your first year).
  • The Unity 6.6 LTS recipe is a 60-line TelemetryClient.cs using UnityWebRequest; the Godot 4.5 recipe is a 60-line telemetry.gd autoload using HTTPRequest. Zero third-party dependencies in either case.
  • Set $ip: null in every event - the most common 2026 audit miss is silent IP collection.
  • Pick one of three 2026-compliant opt-in patterns: opt-out (US-only, lowest-friction), region-aware default (recommended indie sweet spot), opt-in everywhere (most conservative).
  • Eight common beginner mistakes to avoid: logging PII, linking distinct_id to platform IDs, missing $ip null, synchronous events, no offline buffer, guessable distinct_id paths, skipping privacy disclosure, skipping the dashboard step.
  • Build the one-chart funnel dashboard before you ship the event - "% of users who complete the final tutorial step within 30 minutes" is the most actionable indie metric you can collect.
  • Document the privacy posture in a one-page release-evidence/privacy.md and link from in-game About menu plus every platform privacy field; quarterly re-audit takes 30 minutes if kept current.
  • Pair the telemetry pipeline with the deterministic replay hook for bug-reproduction (telemetry surfaces drop-off; replay reproduces stuck state) and the 30-minute Friday operating review (Block 1 metric).

Frequently Asked Questions

Do I really need to set up analytics at all? My game just launched and I have 50 players.

Honestly, no - 50 players is too small for statistically meaningful analytics. But the ninety-minute setup pays off as soon as you cross 500 players or run a Next Fest demo (where you might get 5000 players in a week). Wire it up while it's quiet so the infrastructure is ready when the numbers arrive.

Why PostHog instead of Google Analytics, Firebase, or Unity Analytics?

Three reasons: PostHog has a generous free tier with no surprise billing, supports anonymous event tracking out of the box (Google Analytics does too but its UI nudges you toward PII collection), and lets you self-host if you want full control. Firebase and Unity Analytics work but their default configurations collect more than indie-safe in 2026; you can configure them down but it's more setup work. PostHog's defaults are closer to the indie-safe envelope.

Does this work for mobile (Quest, Google Play, App Store) or only desktop?

It works on all of them. The Unity recipe is identical on mobile (it's just UnityWebRequest). The Godot recipe is identical on mobile (it's just HTTPRequest). The privacy-policy implications are slightly different per platform - Apple's ATT is more sensitive than Steam's privacy posture - but the recipe code is unchanged.

What about Plausible Analytics or Matomo?

Plausible is web-analytics focused (script-based, not event-API-friendly for desktop game telemetry); not the right tool. Matomo (self-hosted, open source, PHP) works but is more setup-heavy than PostHog. If you have a strong privacy stance and want a fully self-hosted option, Matomo is fine; otherwise PostHog Cloud is faster to ship.

My game has a Steam friends-list integration. Does that affect telemetry?

Only if you log Steam IDs to your telemetry backend, which the recipes above explicitly do not do. Steam friends-list usage stays inside Steamworks; your PostHog stays anonymous. Keep the two cleanly separated and you're fine.

Will this telemetry pipeline get my game rejected from any platform?

No - the pipeline as described collects strictly less data than most platforms' default SDKs and is fully disclosed via the one-page privacy posture. The platforms care that you disclose what you collect, not that you collect zero. The recipe is well below the disclosure threshold.

Can I add session replay (PostHog supports it) to capture user flows?

Technically yes, but for games session replay is much heavier than event tracking (large bandwidth, captures more data, harder to anonymize). For your first telemetry event, skip session replay. Once you have event tracking working for three months and a specific question session replay would answer, evaluate it then. Most indie games do not need session replay.

How does this compose with the deterministic soft-lock replay hook piece?

Telemetry tells you where players are getting stuck (the funnel drop-off step); the replay hook lets you reproduce one player's specific stuck state so you can fix it. Use them together: telemetry surfaces "12% of players drop off at tutorial step 4"; replay hook fires when a beta-tester hits the same step 4 stuck state; QA replays the captured state; you fix the bug; telemetry confirms the drop-off rate dropped in the next patch. Round-trip closed.

Conclusion

Your first telemetry event is the single highest-leverage ninety-minute investment you can make in your indie game in 2026. It transforms post-launch decisions from "I think players are dropping off at the tutorial" to "47% of players complete tutorial step 3 but only 18% complete step 4 - step 4 needs work." The infrastructure cost is one evening; the maintenance cost is 30 minutes per release; the decision-quality improvement compounds over your game's entire lifetime.

The 2026 privacy framework rewards teams that ship narrow, well-disclosed, anonymous telemetry over teams that drop heavy SDKs and update Data Safety post-hoc. The recipe above is the indie-safe envelope: one event, two properties, zero PII, full disclosure.

90 days from today - going into the autumn 2026 platform-policy refresh window with a one-page privacy posture, a single-chart dashboard, and ninety days of accumulated tutorial-completion data - you and your team will be in a markedly better decision-making position than the team still shipping on gut feel.

Ninety minutes. One event. Six follow-up events over the next month. One dashboard. One privacy posture page. That's the entire 2026 indie-data starter pack.
