We retain data only as long as needed to provide app functionality and comply with legal obligations. You can request deletion of your account/data by contacting us (see section 10).

We use reasonable technical and organizational measures to protect data. However, no method of transmission or storage is 100% secure.

Depending on your location, you may have rights to access, correct, restrict, or delete your data. Contact us for requests.
