Privacy Policy

Tinker Lab · Last updated May 31, 2026

Tinker Lab is a single-player puzzle game. We designed it to collect as little data as possible. There are no user accounts, no logins, no in-app purchases, and no advertising. This policy explains the small amount of anonymous analytics data the app collects and what it never touches.

What we collect

The app uses Google Firebase Analytics to understand, in aggregate, how the game is played so we can improve it. This includes:

• Anonymous gameplay events — for example, opening the game, discovering an invention, and completing a villager's workshop.
• Basic device & usage information — device model, operating system version, app version, language, region (country-level), and general app interaction and session data.
• Identifiers — Firebase Analytics collects the Apple Identifier for Vendor (IDFV) and a Firebase Installation ID. These are per-install identifiers used to count distinct devices and sessions. They are not linked to your name, email, or any personal account.

What we do NOT collect

• No name, email address, phone number, or account credentials.
• No precise location.
• No contacts, photos, microphone, or camera access.
• No advertising identifier (IDFA), and no ads of any kind.
• No payment or financial information.

How the data is used

Analytics data is used solely for first-party purposes: measuring engagement (such as how many players reach each level) and diagnosing problems so we can make the game better. We do not sell your data, we do not share it with data brokers, and we do not use it for cross-app or cross-website advertising. Google Signals is not enabled.

Tracking

The app does not track you in the sense defined by Apple's App Tracking Transparency framework: we do not link your data with third-party data for targeted advertising, and we do not share it with data brokers. The app therefore does not show an App Tracking Transparency prompt.

Data retention

Anonymous analytics data is retained by Google Firebase according to its standard retention settings (up to 14 months), after which it is automatically deleted. Your game progress is stored only on your device and is removed when you delete the app.

Third-party services

Firebase Analytics is provided by Google. Its handling of data is governed by Google's Privacy Policy: https://policies.google.com/privacy.

Children

Tinker Lab does not knowingly collect personal information from children. The app has no chat, no social features, and no purchases. The analytics described above are anonymous and not directed at identifying any individual.

Your choices

You can stop all analytics collection at any time by deleting the app. Because the game requires no account, removing the app removes your association with any collected data.
