Frequently Asked Questions (FAQ)

The app won’t start or is unstable

Please try the following, in order.

  1. Restart your device
  2. Update the app to the latest version
  3. If that does not help, delete the app and install it again

Please check this before trying step 3. If you are using the app without signing in (as a guest), deleting the app will lose the records stored on your device. If you sign in from the app’s settings first, your records will carry over when you reinstall.

If the problem persists, please contact us using the details above. It helps if you can tell us the app name and version, your device and OS, the symptoms, and the steps to reproduce them.

I want to delete my account

You can request deletion yourself at any time from the app’s settings. There is no need to contact us.

For 2iro, this works as follows.

  • Deletion takes place 30 days after you request it
  • Until then, you can cancel it by signing in the same way
  • If you would rather not wait, you can choose “Delete now”

Unpairing is a different action from deleting your account. Unpairing does not erase your records.

If for some reason you cannot do this from the app, please request it through the contact details above. For more detail, see the 2iro privacy policy.

How is my data handled after I leave?

Account information such as your credentials and date of birth is deleted.

In an app used by two people, such as 2iro, shared records also belong to the other person, so they are not erased simply because one of you has left.

  • Records shared by the two of you (messages, anniversaries, the shared calendar, notes, places to go, and so on): deleted once both of you have left
  • Body records, cycle records and meet-up locations: deleted at the time you leave
  • Display name and avatar colour: kept within the shared records so that the other person’s screen is not broken

The handling differs between services, so please see the 2iro privacy policy for details.
