Help & support

No. There are no accounts and no sign-in. Your progress, mistakes, bookmarks and settings are stored on your device.

Everything lives on your device. To move to a new phone, use the built-in backup:

• On the old device: Settings → Back up / Export, and save the file somewhere you can reach it (Files, iCloud Drive, email to yourself, etc.).
• On the new device: install R0 Pass, then Settings → Restore and pick that file.

Restoring replaces the app's current data with the backup's contents.

You're always in control. Clear your history and other data from within Settings, or simply delete the app to remove everything from your device. We don't hold a copy on any server, so there's nothing on our side to delete. If you've used the AI helper, cached answers on our service are not linked to you and expire automatically within 30 days.

Purchases are handled by Apple. Use Restore purchases (on the paywall or in Settings) while signed in to the same Apple ID you bought with, and your unlocks will come back. If it still doesn't work, email support@r0pass.com with the Apple ID email you purchased with and we'll help.

Many questions include a written explanation that works fully offline. Where the live AI helper is available and you turn it on, your typed follow-up plus that question's text is sent securely to our AI service (OpenAI, via our own proxy) to generate an answer. We don't send your name, email, location or your scores. It's optional, off by default, and there's a fair daily limit. Full detail is in our Privacy Policy.

AI answers are generated and can be wrong — treat them as study help, not financial advice, and check figures against the latest CII study text.

Please tell us — accuracy matters most in a revision app. Use the "Report a problem" link on the explanation if it's there, or email support@r0pass.com with the unit and, if you can, the question wording. Every practice question is original; if something reads as inaccurate we'll review and correct it.

Exam-date reminders are optional and scheduled locally on your device. Make sure you set an exam date and enabled reminders in Settings, and that notifications are allowed for R0 Pass in your phone's system settings.

No. R0 Pass is an independent revision resource. It is not affiliated with, endorsed by or approved by the CII. Unit codes like "R01" are used only to describe which exam the material helps you revise for.
