Reading the label

What Clean Storage: Master Cleaner's label means for you

Clean Storage: Master Cleaner's label has 4 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 purchases, identifiers, usage data, other data from Clean Storage: Master Cleaner 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.

Video storage apps upload large personal files, often including faces and voices of other people. Check upload settings over cellular, who can access shared videos and how to delete a video from the server, not just the app.

Among the 108 video storage apps in our snapshot with a label, 72% declare tracking, 80% collect data linked to you and 14% say they collect nothing. Clean Storage: Master Cleaner lists 5 data types, more than the average of 2.9 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 Clean Storage: Master Cleaner

  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

    Photos

    Settings › Privacy & Security › Photos. Limited Access lets you pick exactly which pictures the app can see; Add Photos Only lets it save without reading your library.

  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 › Clean Storage: Master Cleaner › Show Previews: When Unlocked keeps message and account details off the Lock Screen.

Cross-app tracking

iOS 18 and later

Lock Clean Storage: Master Cleaner behind Face ID

  1. Find Clean Storage: Master Cleaner 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. Clean Storage: Master Cleaner now asks for authentication every time it opens.

The lock is an iPhone feature, so it works whether or not Clean Storage: Master Cleaner 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 Clean Storage: Master Cleaner 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.
