Line by line

What Fast Scanner - PDF Doc Scan collects, explained

Data typeWhat it coversWhere to limit it
IdentifiersNot linked to you An account ID, screen name, customer number or a device-level ID such as the advertising identifier. Settings › Privacy & Security › Tracking: turn off Allow Apps to Request to Track, or tap Ask App Not to Track when prompted.
Usage DataNot linked to you What you tap, open and view inside the app, plus which ads you have seen. There is no single iOS switch. Look for an analytics or personalised-ads toggle in the app's own settings.
DiagnosticsNot linked to you Crash logs, launch times, hang rates and energy use. Settings › Privacy & Security › Analytics & Improvements › Share With App Developers controls what Apple passes on; the app's own crash reporting is separate.
Reading the label

What Fast Scanner - PDF Doc Scan's label means for you

Fast Scanner - PDF Doc Scan's label has 3 types under “Data Not Linked to You”. A data type can appear in more than one section when it is used for different purposes — for example, identifiers used for both analytics and advertising.

Every type on Fast Scanner - PDF Doc Scan's label is in the “not linked” section, so the developer says the data is stripped of anything that identifies you before it is used. That is typical of anonymous analytics and crash reporting. Not linked is still collected: the data leaves your phone.

None of the data types fall into the categories most people consider sensitive: health, financial information, precise location, contacts, browsing history or the content you create.

Scanners handle IDs, contracts, receipts and medical letters. Many offer cloud OCR, which means your document images leave the phone. Prefer on-device text recognition where offered, and check whether scans sync to the developer's cloud by default.

Among the 173 document scanners in our snapshot with a label, 64% declare tracking, 68% collect data linked to you and 20% say they collect nothing. Fast Scanner - PDF Doc Scan lists 3 data types, about the same as the average of 2.8 for this group.

Business apps often handle other people's data — clients, colleagues and customers — so what they collect can affect more than you.

Read with care

What the label cannot tell you

  • A label is self-reported. Apple publishes the developer's answers and can reject apps that misrepresent them, but it does not independently verify what Fast Scanner - PDF Doc Scan sends.
  • It does not say where data is stored, how long it is kept, whether it is encrypted, or which companies receive it. The privacy policy covers those points.
  • Optional data counts: if a feature lets you add something (a profile photo, a phone number), the type is listed even if you never use the feature.
  • Data handled only on your iPhone is not 'collected', so a no-collection label is compatible with an app that reads your files locally.
  • Third-party sign-in, payment processors and SDKs are supposed to be included, but a label can lag behind a new version.

The question to ask Fast Scanner - PDF Doc Scan's developer: Are my scans processed on the phone or uploaded for OCR?
