Matches the label

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

Matches the label

55 Messenger lists User Content on its label. Choose Limited Access and pick only the photos you want to share.

Not on the label

Contacts is not on 55 Messenger'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

55 Messenger 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 55 Messenger'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 55 Messenger's label means for you

55 Messenger's label has 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.

Every type on 55 Messenger'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.

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

Messengers see who you talk to as well as what you say. Even with end-to-end encrypted content, contact lists and metadata can be collected and linked to you. Check whether contact upload is optional, whether backups are encrypted too, and whether disappearing messages exist.

Among the 172 secure messengers in our snapshot with a label, 14% declare tracking, 54% collect data linked to you and 29% say they collect nothing. 55 Messenger lists 5 data types, more than the average of 2.8 for this group.

Social apps are built around identity and contacts, so data linked to you is nearly universal. Tracking and contact upload are the settings worth checking.

On your iPhone

Settings to check for 55 Messenger

  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 › 55 Messenger. Choose While Using or Never, and switch off Precise Location if a city-level answer is enough.

  3. 3

    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.

  4. 4

    Contacts

    Settings › Privacy & Security › Contacts. Limited Access shares only the people you select instead of your whole address book.

  5. 5

    Microphone & camera

    Settings › Privacy & Security › Microphone and Camera. The orange and green dots in the status bar show when either is in use.

  6. 6

    Sign-in

    When creating an account, Sign in with Apple can give the app a relay address from Hide My Email instead of your real one.

iOS 18 and later

Lock 55 Messenger behind Face ID

  1. Find 55 Messenger 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. 55 Messenger now asks for authentication every time it opens.

The lock is an iPhone feature, so it works whether or not 55 Messenger 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 55 Messenger 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 55 Messenger's developer: Is the message content end-to-end encrypted by default, including backups?
