Account and Data Deletion – Mariner's Book

Effective date: August 17, 2026 · Package: com.marinersbook.app · Data controller: Nautical Leap · Contact: nauticalleapapps@gmail.com

See also the Privacy Policy.

You can permanently delete your Mariner's Book account and all associated data. There are two ways to do it and both have the same result. You do not need an account on this page, and nothing here needs to be filled in — deletion is requested either in the App or by email.

1. Delete from within the App

  1. Open Mariner's Book and sign in to your account.
  2. Go to Settings → Account.
  3. Tap "Delete my account".
  4. Read the warning, then confirm with "Yes, delete my account permanently".

Once you confirm, your account and the data listed in section 3 are erased from our servers. This cannot be undone.

2. Request deletion by email (no App required)

If you no longer have the App installed or cannot sign in, email nauticalleapapps@gmail.com from the address registered to your account, with "Account deletion request" in the subject line.

The request must come from your account's email address so that we can verify it is yours. Requests are handled within 30 days, and we confirm in writing once the deletion is complete. The outcome is identical to deleting the account in the App.

3. Data that is deleted

DataStatus

AI chat historyStored only on your device, never on our servers; removed when you clear the App's data or uninstall it

4. Data that is not deleted

Payment and invoice records for purchases made through Google Play are held by Google, not by us, and we cannot delete them. They remain subject to Google Play's own retention periods. Deleting your account does delete the purchase record held in the App, as listed above.

5. If you have a subscription

Deleting your account does not cancel your Google Play subscription. To stop being billed you must also cancel it separately under Google Play > Subscriptions. Cancel the subscription before deleting your account, otherwise billing continues even though the account is gone.
