When reporting a problem

It helps to include the app version (shown at the bottom of Settings), your phone model, and what happened step by step. If you attach screenshots, please hide personal content such as your letters. Please do not send sensitive information such as passwords or ID numbers.

When ocean data is slow

To move a bottle, the app has to download a day’s worth of ocean data, and each batch can take several tens of seconds. Please check your internet connection and wait a moment. If a data server is under maintenance, your bottles catch up on the missed days the next time you open the app. Ocean forecasts are published a few hours late, so the app sometimes moves bottles with yesterday’s data instead of today’s.

Deleting records stored on your device

Delete everything: In Android settings, open Drift Letter’s storage and clear the app data. This removes your letters, bottles, drawer and settings. Menu names differ by device.
Uninstall: Uninstalling the app also removes the records stored on the device.

Deleted records cannot be brought back. Before clearing the app data or uninstalling, it is best to use Delete my statistics below first.

Restoring Premium

If you reinstalled the app or changed phones, open Drift Letter Premium in Settings and tap Restore purchase. You need to be signed in to Google Play with the same Google account you used to buy Premium. If no purchase is found, check that you are not using a different Google account; if it still does not work, email us with your order number (it starts with GPA.).

Accounts and server storage

Drift Letter does not create member accounts, so there is no account deletion page. We cannot view, or delete on your behalf, letters stored only on your device. For how technical information handled by service providers and support emails are kept and deleted, see the Privacy Policy. Requests to access, correct or delete your personal information, or to suspend its processing, can be sent to the email above.

Stopping and deleting usage statistics

Turn off Usage statistics in Settings to stop sending statistics from then on. To delete the statistics this device has already sent, choose Delete my statistics. When deletion on the server succeeds, a confirmation appears and sending stays off. If it fails, check your connection and try again. The app does not display the installation number, so even if you ask by email we may not be able to identify your records; in that case they are cleaned up when the retention periods in section 4 of the Privacy Policy end.

Ad privacy choices

You can reopen Google’s privacy choices from Ad privacy settings in the app’s Settings. This item appears only when needed, depending on your region and consent status. In your device settings, you can reset or delete your Android advertising ID.
