Short answer

On the label it is low-risk: Puffin Cloud Browser collects some data but says none of it is linked to you or used for tracking. None of it falls in Apple's most sensitive categories (health, financial, location, contacts or your own content). In total the label lists 1 data type; 32% of private browsers we checked declare tracking.

Not on the label

Location is not on Puffin Cloud Browser's label. That can be fine: data used only on your iPhone does not have to be declared. If the data would need to leave the phone for the feature to work, ask why it is missing.

User Content is not on Puffin Cloud Browser's label. That can be fine: data used only on your iPhone does not have to be declared. If the data would need to leave the phone for the feature to work, ask why it is missing.

Contacts is not on Puffin Cloud Browser's label. That can be fine: data used only on your iPhone does not have to be declared. If the data would need to leave the phone for the feature to work, ask why it is missing.

Not declared on the label

Puffin Cloud Browser declares no tracking, so a tracking prompt would contradict its label. Decline it, and consider reporting the mismatch to Apple.

Not on the label

Health & Fitness is not on Puffin Cloud Browser's label. That can be fine: data used only on your iPhone does not have to be declared. If the data would need to leave the phone for the feature to work, ask why it is missing.

A permission is what the app can reach on your iPhone; the label is what the developer says leaves it. They answer different questions.

Reading the label

What Puffin Cloud Browser's label means for you

Puffin Cloud Browser's label has 1 type 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 Puffin Cloud Browser'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.

A private browser should collect less than the sites it visits. Browsing History or Identifiers on its label are worth a second look. Check the default search engine, whether history syncs to an account, and whether tracker blocking is on by default.

Among the 160 private browsers in our snapshot with a label, 32% declare tracking, 39% collect data linked to you and 31% say they collect nothing. Puffin Cloud Browser lists 1 data type, fewer than the average of 2.1 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 Puffin Cloud Browser behind Face ID

  1. Find Puffin Cloud Browser 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. Puffin Cloud Browser now asks for authentication every time it opens.

The lock is an iPhone feature, so it works whether or not Puffin Cloud Browser 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 Puffin Cloud Browser 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.
