We're here to help. For any question, bug, or request about your account or your data, write to us:

Managing your data

Every request below can be made by email, and deleting your account also works in the app, under Settings → Privacy & data. The email route matters — if you have already uninstalled QuitDuo, or cannot sign in, you should never have to reinstall the app to get a copy of your data or have it erased.

Please write from the email address your account uses, so we can match your request to your account. If you signed in with Apple and chose Hide My Email, Apple does not let you start an email from that relay address: write from any address and tell us, and we will confirm through your relay address that the account is yours before we act.

• Get a copy of your data
  There is no button for this in the app. Write to hello@aiovent.com from your account's address — with Hide My Email, from any address and tell us — and we will send you a copy of your data within one month.
• Erase your archived logs
  If any of your logs have been moved into the separate archive we use to improve the pacing algorithm (see Retention in our Privacy Policy), you can have them erased on their own. There is no separate in-app control for this, so it is an email request: write to hello@aiovent.com and we will erase them and confirm in writing, leaving the rest of your account untouched. Deleting your account erases them too.
• Delete your account
  In the app: Delete my account — type DELETE, then confirm it's you by re-entering your password or, if your account signs in with Google or Apple, by signing in with it once more. This erases your profile, logs, craving notes, plans, messages, rewards, journal, Observer links, alerts, your list of blocked people, and any reports you sent us or that name you, and deletes your sign-in account. For an account that signs in with Apple, the app also asks Apple to revoke QuitDuo's Sign in with Apple authorization.
  By email: write to hello@aiovent.com from your account's address and we erase your account and everything in it within 30 days. Both routes, and the full list of what is deleted, are on Delete your account.

Details are in our Privacy Policy.

Trouble signing in

Email and password: use the "Forgot password?" link on the sign-in screen to get a reset email. If the email doesn't arrive, check your spam folder, then write to hello@aiovent.com for help.

Google or Apple: an account you created with Google or Apple has no QuitDuo password. Tap "Continue with Google" or "Continue with Apple" again and choose the same Google account or Apple ID you used before. Sign in with Apple is offered only in the iPhone app; on Android, QuitDuo offers Google and email.

• If the app says an account with this email already exists, sign in the way you did when you first signed up — with your email and password, or with Google or Apple.
• If you chose Hide My Email with Apple, that sign-in always has its own account, separate from any account you created with your real email address.
• If you created your account with a Gmail address and a password and later chose "Continue with Google" with that same address, Google sign-in can replace your password: if it does, your account and data stay the same, and from then on you sign in with Google.

Your Observer link

Either of you can end the link at any time in Settings → Support ("Remove Observer" or "Stop supporting"); the Observer's access stops at once. If the link ends while the Smoker's step-down is running, it pauses until a new Observer joins, and the program's 90 days keep running.

If someone makes you uncomfortable, use Report or Block in the same place while you are linked; a Smoker can also report a single message from their Observer. A report sends us the reason you chose and what you reported, and we review every report, usually within 24 hours. Blocking ends the link at once and stops that person from linking with you again; you can undo a block under Blocked people. For anything urgent, email hello@aiovent.com directly.

Purchases and refunds

QuitDuo is free to install, and Observers never pay. A Smoker's first 7 days are a free trial that includes personal AI messages. The 90-day program is a one-time purchase made through the App Store or Google Play: it never renews, and starting again later is a new purchase. Apple or Google handles the payment and keeps the receipt, so please ask Apple or Google directly for a refund. If something went wrong with the app itself, write to us at hello@aiovent.com and we will help.

A note on your wellbeing

QuitDuo is a habit-change tool, not a medical service. If you need clinical help to stop smoking, please speak to your doctor or a national quit-line. In Germany you can call the Rauchfrei-Telefon on 0800 8313131. If you are in crisis, contact your local emergency services.
