Data stored on your device

Last updated: 2026-11-05

TCGVerse is an app, not a website: it uses no browser cookies. What it does use is storage on your device, for this.

1. YOUR PREFERENCES

Language, country, currency, theme, whether you already accepted the legal notice, which game is active and how you like to view your collection. It lives only on your device.

2. YOUR SESSION

Firebase Authentication securely stores the fact that you are signed in, so it does not ask for your password every time you open the app. Firebase App Check keeps, while it is valid, the proof that the app is genuine (point 4 of the privacy policy). And if you open the plans screen, RevenueCat keeps its own copy of your purchase status.

3. YOUR CARD PHOTOS

If you save a photo of a card, the file stays in the app's private storage on your phone. It is not uploaded anywhere.

4. CARD IMAGES

Catalogue images you have already seen are kept in an app cache, so they are not downloaded again. They come from the servers that publish them (see point 6 of the privacy policy).

5. A COPY OF YOUR COLLECTION, SO YOU CAN SEE IT OFFLINE

The app keeps the server's last answer with your cards and their catalogue data, so it can show them to you when you lose signal. It is a copy of what is already yours and it is not shared with anyone: it just stops the app going blank on the underground.

It refreshes itself whenever there is a connection, and it goes away when you delete your account or uninstall the app.

6. ANALYTICS

If — and only if — you turn analytics on in Profile, a random installation number is also stored, so events from one device can be grouped without knowing whose it is. It is not your account identifier and cannot be linked to your email.

With analytics off, which is how it ships, that number is not stored and nothing leaves the device.

7. WHAT THERE IS NOT

No advertising cookies, no social network pixels, no third-party trackers. Fonts are bundled inside the app: they are not requested from anyone.

Apart from the services that make the app work —Firebase for the session and the genuine-app proof, and RevenueCat if you open the plans; they are all in point 9 of the privacy policy—, only two things go to third parties: card image requests from point 4, which see your IP like any website, and the analytics in point 6, and that only if you switch it on yourself.

8. HOW TO DELETE IT
