Cellwise – Nonogram: Privacy Policy

Last updated: 24 October 2026

Cellwise is a puzzle game by InfiV Labs that runs entirely on your device.

What we collect

No name, email or account. The app has no sign-in and no server of its own. The services below use device identifiers (an advertising ID, random app ids) as described there.
Puzzle progress, settings, coins and purchases are stored only on your device, in the app's private storage. Android may include them in your device backup. You can export them as a file from Settings and delete them by uninstalling the app.
The share card and the backup file go only where you send them from the share sheet.

Google AdMob shows ads to players without Premium. To serve and measure ads, Google's SDK may use the advertising identifier, device and app information, ad interactions and an approximate location derived from your IP address. In the EEA, the UK and Switzerland you are asked for consent through Google's consent form before any ad loads, and you can change your choice at any time under Settings → Privacy options. Google's policy: https://policies.google.com/technologies/ads
RevenueCat processes purchase and subscription receipts so Premium can be restored on a new device and a lapsed subscription is recognised. It receives an anonymous app user id and the store receipt, never your name or email. Policy: https://www.revenuecat.com/privacy
Google Play (and the Apple App Store, where the app is offered there) handles payment and your subscription. We never see your card details.
Firebase Analytics and Crashlytics (Google) tell us which features are used and why the app crashed. Analytics receives app interactions (for example that a puzzle was opened or solved), app and device information and a random app-instance id; Crashlytics receives crash logs and diagnostics (device model, OS version, app version, memory). None of it is linked to an account, and the app sets Google's consent flags so this data is never used for ads. Policy: https://firebase.google.com/support/privacy

On your device: until you delete it. Uninstalling the app, or clearing its storage in Android settings, removes your progress, settings and coins.
Firebase Analytics keeps event-level data for 2 to 14 months (the project's retention setting) and keeps aggregated, anonymous usage reports; Crashlytics keeps crash reports for 90 days.
RevenueCat keeps purchase records for as long as the store requires them for refunds, restores and accounting.
Google AdMob keeps ad data under Google's policy linked above.
None of this is tied to a name, email or account, so we cannot look it up by person; event data and crash reports expire on the schedule above. Questions about your data: infivlabs@gmail.com.

Everything the app sends goes over encrypted connections (HTTPS) to the services above. We run no server of our own and keep no copy of your data.

Change or withdraw ad consent: Settings → Privacy options.
Reset your advertising identifier or opt out of personalised ads: your device's Google settings → Ads.
Export your data: Settings → Export progress. Delete it: uninstall the app (the services' copies expire as described above).

The app is rated for ages 13 and up and does not knowingly collect data from children.

We may update this policy; the version on this page applies, with the date above.
