Privacy Policy

Updated October 22, 2026

Handful of Fins is developed by zehao li (FunYoru Studio). It needs no account and contains no advertising, analytics or tracking. The app does not collect personal data, and nothing is shared with us or with third parties.

Offline play and saves

The game runs offline and loads only files bundled with the app. Your tank, companions, settings and album are stored on your device, in the app's own storage. Deleting the app removes them. The game reads your language, text size and reduced-motion settings only to lay itself out; it does not store or send them.

Purchases

The Sea Ticket and Promise Bait are bought through the App Store or Google Play, under Apple's or Google's terms and privacy policy. We never receive your payment details. The app checks the store's signed purchase record on your device; it does not send that record to us.

Photos

Photos of your tank are made on your device and stay in the app's album. A photo leaves your device only if you share it with the system share sheet. If you choose Save Image on iPhone or iPad, iOS asks for permission to add to your Photos; the app can only add the picture and cannot see your library.

System services

Store, backup and diagnostics services that you enable in your device settings are run by Apple or Google under their own privacy policies.

Changes

If the app's handling of data ever changes, for example if it starts sending anything off your device, we will update this page and the store privacy details before that version is released.

Support correspondence

If you email support, we receive your email address and what you send. We use it only to reply and resolve your request, and keep it only as long as that needs. You can ask us to delete it by email.
