Open your registration details, request account closure, or request deletion of personal data while limited sale records may still be retained where required.

Info & Legal

Open app information, privacy details, support help, and the FlipUnits Pro page without leaving the app.

Install App

Install FlipUnits for a faster app-like experience.

Android: Open your browser menu and choose Install app or Add to Home screen.

iPhone/iPad: Tap Share, then choose Add to Home Screen.

My Registration

Open the details saved on this device for support and restore help.

No saved registration has been found on this device yet. If you have already bought FlipUnits Pro, open the registration page and confirm your details again.

Tip: deleting the app is not the same as closing your account or deleting your data. Those are separate actions.

Close Account

Closing your account is separate from uninstalling the app and separate from asking us to delete your personal data.

Delete app: you remove FlipUnits from your device.
Close account: you ask us to mark your account inactive and stop normal support or restore handling.
Delete my data: you ask us to erase or anonymise personal data where appropriate, while limited sale records may still be retained where required.

No saved registration details were found on this device. You can still contact support if you need help closing your account.

Are you sure? Closing your account can affect future restore help. You will be asked to confirm before either close-account action runs.

Confirm Registration

For backup, restore support, and reinstall assistance, please confirm the details for this device.

Device registration

This copy of FlipUnits Pro is registered on this device with the following details:

Name Phone number

Please add your name and phone number, then confirm registration.

Registration saved successfully.

These details will help with reinstall support and restore requests if you ever need manual help.

These details help us support reinstalls and restore access if you change browser, clear data, or need manual help.

Delete My Data

This is the privacy action for deleting or anonymising personal data. It is separate from deleting the app and separate from closing your account.

Please note: where legally required, limited sale or payment records may still need to be retained even after personal account data is erased or anonymised.

No saved registration details were found on this device. You can still contact support to request erasure if you completed a purchase before.

Are you sure? You will be asked to confirm before deleting data. The local option only clears the copy saved on this device, while Airtable changes still need to be handled by support.
