How Sufoc handles information
Sufoc iOS · 1 September 2026
Sufoc is a private due board that stays on one iPhone. You scan or type an ISBN, photograph or import a jacket, set a reading status or due day, and optionally file a due slip into Photos. There is no public catalog and no chat.
What stays on the phone
ISBNs, titles, jackets, spoken titles, the keeper portrait, display name, due days, borrower names, extra out slots, Leaves balance, and filed due slips are stored in on-device files. Sufoc does not run an account server and does not sell that material.
When the system asks for access
Sufoc asks only when you tap a control that needs it:
- Camera — Scan ISBN or Take jacket, and Camera on Keeper
- Photo library — Choose jacket, Album on Keeper, and File due slip on an out copy
- Microphone — Speak title on Add copy
- Notifications — after Continue, Apple’s system sheet
- Tracking preference — Apple’s App Tracking Transparency sheet after Continue. Sufoc does not use an advertising identifier to follow you into other companies’ apps or websites. Scanning an ISBN, setting a due day, and opening the due board still work if you decline.
Apple purchases
Flyleaf Pack and other Leaves packs are consumable In-App Purchases. Apple processes payment. Sufoc does not see your full card number. Leaves live on this phone and are not restored after the app is removed or the due board is deleted.
Titles and names
A local word check may reject a title, borrower name, or display name before it is saved. Sufoc does not publish copies to other people.
Who else sees your jackets
Jackets, spoken titles, and due slips are not uploaded to third-party automated analysis services.
Age
Sufoc is not aimed at children under 13. Use it only if you meet the minimum age in your region.
