Reading the label

What PDF Reader Editor & Viewer's label means for you

PDF Reader Editor & Viewer's label has 1 type under “Data Used to Track You”, 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.

Tracking is the declaration that most separates apps. It means usage data from PDF Reader Editor & Viewer can be combined with data from other companies to target or measure ads, or shared with data brokers. On iOS 14.5 and later, the app must ask your permission before tracking you through the advertising identifier; answering “Ask App Not to Track” blocks that identifier and tells the developer you have declined.

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.

PDF editors open contracts, tax forms and IDs. Online conversion features can send whole documents to a server. Check which features work offline and whether files are deleted from the server after conversion.

Among the 170 pdf editors in our snapshot with a label, 47% declare tracking, 53% collect data linked to you and 28% say they collect nothing. PDF Reader Editor & Viewer lists 3 data types, about the same as the average of 2.2 for this group.

Utilities range from calculators to VPNs, so their labels vary more than any other category. A simple tool that collects identifiers and usage data for tracking is a sign of advertising SDKs.

iOS 18 and later

Lock PDF Reader Editor & Viewer behind Face ID

  1. Find PDF Reader Editor & Viewer on your Home Screen or in App Library.
  2. Touch and hold the icon until the quick-actions menu opens.
  3. Tap Require Face ID (or Require Touch ID / Require Passcode, depending on your iPhone).
  4. Tap Require Face ID again to confirm. PDF Reader Editor & Viewer now asks for authentication every time it opens.

The lock is an iPhone feature, so it works whether or not PDF Reader Editor & Viewer has a passcode of its own. It does not change what the app sends to its developer.

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 PDF Reader Editor & Viewer 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.
