Privacy policy
Last updated: November 12, 2026
Soi is developed by Nguyen Tin. The app collects no personal data, requires no account and has no advertising, behavioural analytics or tracking tools.
Photos and ingredient labels
Photos you take or select are recognised with Apple Vision on your device. Soi does not upload images or recognised text to a server. It only reads the images you explicitly select through the iOS photo picker.
History and preferences
Scan results, your watch list and preferences are stored on your iPhone. History stores results and additive codes, not a copy of the original photo. You can delete individual or multiple results in Scan history, or clear everything in Settings → Clear history. Device backups, if enabled, are managed by iOS and your Apple settings.
Camera access
Soi asks for camera access when you choose to take a label photo. You can decline or change this in iOS Settings and still choose an existing image or paste text.
In-app purchases
Apple processes payments and restores for Soi Pro through StoreKit. Soi checks your entitlement on the device. The developer does not receive payment card details.
External sources and support
When you choose to open a link to FDA, EFSA, Open Food Facts or another website, that service has its own privacy policy. If you email support, information you choose to send is used to respond to your request. Avoid sending unnecessary personal information.
Children and policy changes
Soi does not collect data from any user, including children. If our data practices change, this page will be updated.
This website
This static website is hosted by Vercel and has no advertising or analytics scripts. Vercel may process technical request information, such as IP addresses, to deliver and secure the service. Website hosting does not change the app’s on-device image processing.
