Matches the label

Cool Browser lists Location on its label. Choose While Using and turn off Precise Location if the feature works without it.

Not on the label

User Content is not on Cool 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 on the label

Contacts is not on Cool 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.

Expected — and you can decline

Cool Browser declares data used to track you, so expect the “Allow to track?” prompt. Tap Ask App Not to Track; the app must keep working without it.

Not on the label

Health & Fitness is not on Cool 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.

What Cool Browser collects, explained

Data typeWhat it coversWhere to limit it
LocationSensitiveNot linked to you Where your phone is, either precisely (street level) or approximately (city or area). Settings › Privacy & Security › Location Services: choose Never or While Using, and turn off Precise Location if the app does not need it.
Browsing HistorySensitiveNot linked to you Websites and other content you viewed that is not part of the app. In browsers, use private tabs and clear history; Settings › Apps › Safari has Safari's own controls.
Search HistoryNot linked to you Searches you run inside the app. Look for a clear-history or private-search option in the app.

Reading the label

What Cool Browser's label means for you

Cool Browser's label has 2 types under “Data Used to Track You”, 5 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 Cool Browser 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.

The items that deserve the most attention are location and browsing history. Location history reveals home, work and routines. Precise location deserves the most scrutiny.

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. Cool Browser lists 5 data types, more 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.

On your iPhone

Settings to check for Cool Browser

  1. 1

    Tracking

    Settings › Privacy & Security › Tracking. If “Allow Apps to Request to Track” is off, apps cannot ask, and they are told to treat you as having declined. You can also turn it off for this app alone.

  2. 2

    Location

    Settings › Privacy & Security › Location Services › Cool Browser. Choose While Using or Never, and switch off Precise Location if a city-level answer is enough.

  3. 3

    Lock the app

    On iOS 18 and later, touch and hold the icon and choose Require Face ID. Anyone who picks up your unlocked phone then needs your face, fingerprint or passcode to open it.

  4. 4

    Notifications

    Settings › Notifications › Cool Browser › Show Previews: When Unlocked keeps message and account details off the Lock Screen.

Cross-app tracking

Does Cool Browser track you?

Yes — 2 data types

Identifiers and usage data. Apple defines tracking as linking data from this app with data from other companies' apps, websites or offline sources for targeted advertising or ad measurement, or sharing it with a data broker.

iOS 18 and later

Lock Cool Browser behind Face ID

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

The lock is an iPhone feature, so it works whether or not Cool 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 Cool 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.

The question to ask Cool Browser's developer: Does the browser keep my history on its servers?
