Twin Trace — Privacy Policy

Last updated: 17 July 2026 · Applies to the Twin Trace app for Android · iPhone or iPad? Read the iOS policy

Twin Trace (“we”, “the app”) respects your privacy. This policy explains what data the app handles and why. By using Twin Trace you agree to this policy.

The short version: Your progress is saved on your device. If your device is already signed in to Google Play Games, the app signs you in automatically when it starts and backs your save up to our cloud, so it survives reinstalls and syncs across devices. You can sign out at any time in Settings, and you can ask us to delete your cloud save. The app shows ads through Google AdMob, which uses a device advertising identifier. We do not sell your data.

Information we collect

Game data — your level progress, points, hints, achievements, and settings. Always stored on your device, and — while you are signed in — backed up to our cloud (Google Firebase Firestore) so it can sync across your devices and survive reinstalls.
Account information — when you are signed in (via Play Games or Google), we receive basic account identifiers (name, email, account ID) to identify and secure your saved game. If your device is already signed in to Google Play Games, this happens automatically when you first open the app, without a separate prompt — that is how Play Games works across games. If your device is not signed in to Play Games, no account is created and nothing is uploaded unless you sign in yourself. You can sign out at any time in Settings, which stops the cloud backup.
Device & usage data — to keep the app stable and to show ads, our providers may collect a device advertising identifier, app diagnostics, and crash reports.
Support requests — if you email us, we receive the information you choose to send (such as your email address and the contents of your message), and we use it only to respond to you.

Advertising

We show ads through Google AdMob, which may use a device advertising identifier to serve and measure ads. In regions that require it (such as the EU/UK), you will be asked for consent before personalized ads are shown, in line with Google's consent requirements. If you decline, you will still see ads — just non-personalized ones.

Purchases

In-app purchases (points packs and the Pro upgrade) are processed entirely by Google Play using Google Play Billing. We never see or receive your payment details — we are only told that a purchase completed, so the app can unlock what you bought.

Analytics & crash reporting

We use Firebase Crashlytics to detect and fix crashes. Crash reports contain diagnostic information (device model, OS version, stack traces) and are not linked to the contents of your account beyond an anonymous identifier.

Notifications

With your permission, we send notifications — a daily reminder and occasional announcements via Firebase Cloud Messaging. You can disable notifications at any time in your device settings.

Data sharing

We do not sell your personal data. Data is processed by Google (Firebase and AdMob) acting as our service providers, subject to Google's own privacy policies:

Data retention & deletion

If you are never signed in, your game data stays on your device and we hold nothing at all. Cloud-saved game data is kept while your account exists. To delete it, follow our account & data deletion instructions, or email us requesting deletion and we will remove your stored game document. Any support email you send is kept only as long as needed to resolve your request.

Security

Data that leaves your device — cloud save, sign-in, and purchases — is encrypted in transit and handled by Google's secure infrastructure. Your cloud save is stored under your own account identifier and our database rules only permit that signed-in account to read or write it. Uninstalling the app removes its on-device data.

Children

Twin Trace is not directed to children under 13. We do not knowingly collect personal information from children. If you believe a child has provided us personal information, contact us and we will delete it.

Your rights & choices

Sign out at any time (Settings → Cloud Save → Sign out) — this stops the cloud backup, and the game stays fully playable with no account.
Turn off automatic sign-in for games in the Google Play Games app's own settings, if you would rather it never happen.
Decline ad consent to receive only non-personalized ads.
Reset or limit your advertising ID in your device settings.
Manage notification permissions in your device settings.
Request access to, export of, or deletion of your cloud-saved data.

If you have a privacy question or request — including under laws such as the GDPR (EU/UK) or the CCPA (California) — email us and we will respond.
