ScanRunner is developed by Léo, who you can reach at scanrunner@lolozini.fr. This page explains what the app does with your data. The short answer: it collects nothing. Everything stays on your phone, except what you send yourself.

What the app does not have

• No account, no sign-up.
• No ads, no trackers, no analytics.
• No server: the app connects to no service of mine or of anyone else. On Android, it does not even have permission to access the Internet.

Camera and photos

The camera is only used to recognize cards, and recognition runs entirely on the phone.

• In Live mode, camera frames are read as they come and none is saved.
• In Table mode, the photo is kept while it is analyzed and while you answer, then deleted as soon as you add the cards or drop the photo. If one is left over after a crash, it is deleted at the next launch.

No photo is ever sent anywhere.

Your collection

Your collection (which cards, how many copies) is stored on your phone. It only leaves it if you ask:

• Automatic backup (off by default): you pick a folder, for example in iCloud Drive or Google Drive, and the app writes a copy of your collection there. That copy is then kept by the service you chose, under its own terms; I have no access to it.
• CSV export: you choose where the file is saved.

Purchase

The purchase that unlocks the unlimited collection goes entirely through the App Store (Apple) or Google Play. I receive no payment information; the app only remembers that the purchase was made.

Error report and messages you send me

The app keeps a record of its last 30 technical errors on the phone (a crash, a photo that could not be read). It contains no photo and no collection, and it is never sent automatically.

When you tap "Report a problem" or "Send feedback", your mail app opens with a prefilled message: app version, phone model and system and, for a problem, the latest errors from the record. You read it and decide whether to send it.

Messages I receive are only used to answer you and to fix the app. They are kept while your request is handled, then deleted at the latest one year after our last exchange. They are never sold or shared. My mailbox is hosted by Proton.

Your rights

Since I collect nothing, I hold nothing about you except the messages you sent me. You can ask to see them or have them deleted by writing to scanrunner@lolozini.fr. You can also file a complaint with the CNIL, the French data protection authority.

Uninstalling the app erases everything it stored on the phone. An automatic backup copy stays in the folder you chose: delete it from that service if you wish.

Changes

If the app changes how it handles your data, this page will be updated first, with its date at the top.
