StackWorks handles information in Screenshot Notebook as follows.
1. Information received by the developer
None. There are no accounts, ads, usage analytics or tracking systems. There is no developer server. We do not receive photos, recognized text or usage information.
2. Photos
The app reads only images iOS identifies as screenshots. With limited Photos access, it reads only screenshots among your selected photos. Text, QR codes and image types are recognized using Apple Vision on your iPhone. On supported devices and languages, Apple’s on-device Foundation Models can assist classification. Images and text are never sent to external services.
The app does not save image copies. It stores photo identifiers, capture dates, dimensions, recognized text, categories, extracted information such as numbers, dates and amounts, and small fingerprints for similarity matching.
Photos are deleted only after you select them, proceed to deletion and confirm in the iOS dialog. Deleted photos remain in Recently Deleted for 30 days. Adding photos to selected albums with Plus does not delete them.
With iCloud Photos, unavailable originals are retrieved through Apple’s Photos mechanisms, and deletions also affect other synced devices.
3. Device features
Photos read/write access is used to read screenshots, delete selected items and organize albums. Calendar use only presents the system editor when you choose to add an event; an event is added only after you review and confirm it. The app never reads calendar events.
Background tasks continue reading only as iOS permits. Widgets show counts, space and cleanup candidate counts on the device, without images or recognized text. Apple handles purchases; the developer receives no identifying user information.
4. Data deletion
Deleting the app removes its reading results from the device. Deleting a photo or revoking access to it also removes its results from the app.
5. Audience
The app is a tool for general users.
