We don't collect any personal identifying information. We never capture usernames, the contents of your texts, or your location data.
If you opt-in to analytics on the Android app (thank you - that helps us know what things we need to improve), we will receive anonymized information about user behavior. This includes crash reports, screens used in the app, etc... Analytics is provided by Firebase Crashlytics.
This is an open-source project run by hobbyists, and we try to be completely transparent. If you have questions on this policy, please post on the forum, and we'll reply/clarify/correct.
Keep being awesome!
