Is Lumin - Photo Backup Safe?

Pick the permission prompt you saw. We compare it with what Lumin - Photo Backup's developer declared.

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

   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.

4. 4

   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.

5. 5

   Notifications

   Settings › Notifications › Lumin - Photo Backup › Show Previews: When Unlocked keeps message and account details off the Lock Screen.

Does Lumin - Photo Backup track you? Full answer and how to stop it →

1. Find Lumin - Photo Backup 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. Lumin - Photo Backup now asks for authentication every time it opens.

The lock is an iPhone feature, so it works whether or not Lumin - Photo Backup has a passcode of its own. It does not change what the app sends to its developer.

The current version shipped in October 2026, so the app is actively maintained and its label is likely current. Labels are updated by developers when practices change.

Also by Trustmobi Software Co., Ltd.: SecEMS.

• 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 Lumin - Photo Backup 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.

4. Q4Data “Not Linked to You” is never sent off your iPhone.

   Apple's rules require apps to work the same whether or not you allow tracking.
