Short answer

On the label it is low-risk: Slyd.in 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 2 data types; 14% of secure messengers we checked declare tracking.

Not on the label

Location is not on Slyd.in'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

User Content is not on Slyd.in'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 Slyd.in'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

Slyd.in 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 Slyd.in'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.

Line by line

What Slyd.in collects, explained

Data typeWhat it coversWhere to limit it
Usage DataNot linked 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.
DiagnosticsNot linked to you Crash logs, launch times, hang rates and energy use. Settings › Privacy & Security › Analytics & Improvements › Share With App Developers controls what Apple passes on; the app's own crash reporting is separate.
Reading the label

What Slyd.in's label means for you

Slyd.in's label has 2 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 Slyd.in'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.

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. Slyd.in lists 2 data types, about the same as 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

iOS 18 and later

Lock Slyd.in behind Face ID

  1. Find Slyd.in 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. Slyd.in now asks for authentication every time it opens.

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

  2. Q2Apple tests every app to confirm its privacy label is accurate.

Can I lock Slyd.in with Face ID?

Is the message content end-to-end encrypted by default, including backups?
