Identifiers.
Yes. Scanner App ‐ Scan Documents' developer declares identifiers as data used to track you — data that can be combined with other companies' data for targeted ads or ad measurement, or shared with data brokers. On iPhone you can refuse: tap Ask App Not to Track, or switch off tracking requests for every app in Settings.
What “tracking” means on an iPhone
Apple defines tracking as linking data from this app with data from other companies' apps, websites or offline sources for targeted advertising or ad measurement, or sharing it with a data broker. It is narrower than “collecting data”: an app can collect a lot without tracking you, and a small app can track you with a single advertising SDK.
Since iOS 14.5, App Tracking Transparency requires every app to ask before it accesses your device's advertising identifier or otherwise tracks you. The App Store label is where the developer declares which of its data is used that way. Scanner App ‐ Scan Documents declares 1 data type, so expect the “Allow Scanner App ‐ Scan Documents to track your activity across other companies' apps and websites?” prompt.
The data Scanner App ‐ Scan Documents uses to track you
Identifiers
An account ID, screen name, customer number or a device-level ID such as the advertising identifier. Identifiers let a service recognise the same person or phone across sessions. Combined with other data, they are what makes cross-app tracking possible.
How to stop Scanner App ‐ Scan Documents from tracking you
- When Scanner App ‐ Scan Documents shows the tracking prompt, tap Ask App Not to Track.
- Already said yes? Open Settings › Privacy & Security › Tracking and switch off the toggle next to Scanner App ‐ Scan Documents.
- To refuse every app in one go, switch off Allow Apps to Request to Track on the same screen. Apps then cannot ask, and are treated as if you declined.
- For Apple's own ads in the App Store, News and Stocks, see Settings › Privacy & Security › Apple Advertising and turn off Personalised Ads.
- Inside Scanner App ‐ Scan Documents, look for an analytics or personalised-ads switch in its own settings; it covers data the iOS switch does not.
