Line by line

What PDF Converter Reader for PDF collects, explained

Data typeWhat it coversWhere to limit it

Reading the label

What PDF Converter Reader for PDF's label means for you

PDF Converter Reader for PDF's label has 2 types under “Data Used to Track You”, 2 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 identifiers, usage data from PDF Converter Reader for PDF 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 Converter Reader for PDF lists 2 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.

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 Converter Reader for PDF 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.
