Line by line

What PDF Viewer by Nutrient 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 PDF Viewer by Nutrient's label means for you

PDF Viewer by Nutrient'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 PDF Viewer by Nutrient'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.

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 Viewer by Nutrient lists 3 data types, about the same as the average of 2.2 for this group.

Productivity apps tend to collect the work you do in them — documents, notes and files — so User Content is common. The question is whether it syncs to the developer's servers and how it is protected there.

iOS 18 and later

Lock PDF Viewer by Nutrient behind Face ID

  1. Find PDF Viewer by Nutrient 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 Viewer by Nutrient now asks for authentication every time it opens.

The lock is an iPhone feature, so it works whether or not PDF Viewer by Nutrient 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 Viewer by Nutrient 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.
