Short version: Bight has no account, no ads and no tracking. Your favorites, learned knots and settings stay on your device. Two things leave it, and neither is tied to you: what the App Store / Google Play and our purchase provider need to process and restore your Bight Pro subscription, and anonymous usage statistics (which screens are opened, which knots are viewed, whether a purchase went through).
Your lists and settings never leave your device. Deleting the app deletes all of it, including the random identifier.
In-app purchases are processed by Apple (App Store) or Google (Google Play). We use RevenueCat to verify and restore purchases. RevenueCat receives an anonymous app user ID generated on your device, your purchase history for this app and basic technical information (app version, platform, store country). It is not linked to your name, email or any identity, and it is not used for advertising or tracking. See RevenueCat's privacy policy.
We collect anonymous statistics about how the app is used, through Amplitude, our analytics provider. They exist so we can see which knots people look for, where they get stuck and whether the subscription screen works.
What is sent: the name of an in-app event and a small, fixed set of labels — for example that a screen was opened, that a knot (by its catalog name, such as "bowline") was viewed, learned or shared, that the Knot Finder suggested a knot, or that the subscription screen was shown or closed and whether a purchase succeeded. Each event carries the random installation identifier, the app version, the platform (iOS or Android) and the time. Amplitude, like any web server, also sees the IP address of the request.
What is never sent: your name, email, Apple ID or Google account, location, contacts, anything you type, or your lists of favorite and learned knots as a whole.
The statistics are not linked to your identity, not combined with data from other apps or companies, and not used for advertising or tracking.
No location, contacts, photos, microphone, camera, advertising identifier (IDFA/AAID), crash reports or tracking of any kind. The app does not request any permissions.
Because the statistics are tied only to a random per-installation identifier, we cannot look you up by name or email. Deleting and reinstalling the app creates a new identifier and breaks the link to earlier records. If you want the records from your installation removed, write to us and we will ask Amplitude to delete them.
Bight is suitable for all ages and does not knowingly collect personal information from anyone, including children.
