Matches the label

endlink Secure Messenger lists Location on its label, linked to you. Choose While Using and turn off Precise Location if the feature works without it.

Matches the label

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

Not on the label

Contacts is not on endlink Secure 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

endlink Secure Messenger declares no tracking, so a tracking prompt would contradict its label. Decline it, and consider reporting the mismatch to Apple.

Matches the label

endlink Secure Messenger lists Health & Fitness on its label, linked to you. Approve Health categories one at a time in the Health app.

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

Line by line

What endlink Secure Messenger collects, explained

Data typeWhat it coversWhere to limit it
Health & FitnessSensitiveLinked to you Health and medical records, HealthKit data, and fitness or exercise data. Health app › your profile › Apps: switch off each category the app should not read or write; check Settings › Privacy & Security › Motion & Fitness.
Sensitive InfoSensitiveLinked to you Racial or ethnic data, sexual orientation, pregnancy, disability, beliefs, union membership, genetic or biometric data. Share only what the app needs and check whether the label lists this data as linked to you.
LocationSensitiveLinked 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.
User ContentSensitiveLinked to you Messages, photos, videos, audio recordings, documents and support chats you create or upload. Settings › Privacy & Security › Photos: choose Limited Access or None; review Microphone and Files access too.
Contact InfoLinked to you Your name, email address, phone number or postal address. Use Sign in with Apple with Hide My Email where offered, and check the app's account and marketing preferences.
Usage DataLinked 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.

Reading the label

What endlink Secure Messenger's label means for you

endlink Secure Messenger's label has 7 types under “Data 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.

endlink Secure Messenger declares no tracking, which means the developer says it does not combine your data with other companies' data for advertising or sell it to data brokers. The data linked to you — health and fitness, sensitive info, location, user content, contact info, usage data and diagnostics — is still tied to your identity, typically through an account, and is covered by the developer's privacy policy and retention rules.

The items that deserve the most attention are health and fitness, sensitive info, location and user content. Health data is among the most sensitive data an app can hold, and US health-privacy law (HIPAA) does not cover most consumer apps.

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. endlink Secure Messenger lists 7 data types, more than the average of 2.8 for this group.

Medical apps may hold the most sensitive data on your phone. Whether US health-privacy law applies depends on who runs the app, not on the App Store category.

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 endlink Secure 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 endlink Secure Messenger's developer: Is the message content end-to-end encrypted by default, including backups?
