How can we help?

1. Check the spelling of the email address and search spam or promotions for TMO Books.
2. An OTP is valid for 10 minutes. Request a new one after expiry and use only the newest code.
3. For support, share the approximate request time, time zone, and displayed error wording—never the email address in full or the OTP.

1. Confirm that it is a valid, undamaged PDF and check whether the file is password-protected or access-restricted.
2. Check device file permissions and available storage.
3. TMO Books does not back up or sync your PDF library. Move an authorized original securely when changing devices.

1. Check internet access, sign-in status, remaining translation usage, and translation consent.
2. Remote translation sends extracted page text through TMO Books to Google Gemini only after consent. AI output may contain mistakes, so compare important content with the original.
3. When contacting us, send only the target language, page number, and displayed error code—not the PDF or its text.

1. From the current TMO Books account, including a new account registered after deletion, sign in to the App Store with the Apple account used for the purchase, then expressly choose Restore Purchases in the account or purchase screen. After the server verifies the store transaction, matching purchase entitlements and remaining usage from a deleted account are transferred to the current account.
2. Manage renewal, cancellation, billing, and refunds through Apple. Deleting the TMO Books account does not cancel an App Store subscription.
3. Do not email a receipt or transaction ID. Share only the product name, approximate purchase time, and redacted error wording if support asks for diagnostics.

AdMob privacy choices and Firebase Analytics opt-in are separate. Analytics can be allowed or withdrawn in the app's account/privacy settings. Where Google provides AdMob privacy options for your region, open them from the library or account screen.
