Privacy Policy
FoodLabelScan is designed to work without an account, advertising, third-party analytics, or cross-app tracking. We do not sell personal information.
Information stored on your device
Your watchlist, custom terms, recent scan history, and free-scan counter are stored locally on your device. FoodLabelScan does not operate an account system or a developer-controlled server that receives this information. Removing the app normally removes this local data.
Label photos
When you photograph or select a food label, text recognition is performed on your device using Apple Vision. FoodLabelScan does not upload the image or recognized text. If you choose an existing photo, the app receives only the item you select through Apple’s system photo picker.
Barcode lookups
When you look up a barcode, the barcode number is sent directly to the Open Food Facts service to retrieve a product record. Open Food Facts may receive technical information such as your IP address under its own privacy practices. Do not use a barcode as personal or confidential information.
Rule updates and website
The app may download a public ingredient-rule file from this GitHub Pages site. GitHub may process ordinary network information when serving these files or pages under GitHub’s privacy statement.
Purchases
Subscriptions are processed by Apple. FoodLabelScan receives purchase entitlement status from Apple but does not receive or store your full payment details.
Children
FoodLabelScan is a general-audience utility and does not knowingly collect personal information from children.
Changes and contact
We may update this policy as the app changes. The effective date above will be revised when material changes are published. Questions may be sent to ixxzhu@gmail.com.
