Did Photo Vault Darkbox ask for something?
Pick the permission prompt you saw. We compare it with what Photo Vault Darkbox's developer declared.
Location is not on Photo Vault Darkbox'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.
User Content is not on Photo Vault Darkbox'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.
Contacts is not on Photo Vault Darkbox'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.
Photo Vault Darkbox declares data used to track you, so expect the “Allow to track?” prompt. Tap Ask App Not to Track; the app must keep working without it.
Health & Fitness is not on Photo Vault Darkbox'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.

What Photo Vault Darkbox's label means for you
Photo Vault Darkbox's label has 1 type under “Data Used to Track You”, 1 type 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 diagnostics from Photo Vault Darkbox 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.
A photo vault holds the pictures you least want seen, so the questions that matter are where the files live, whether they are encrypted, and what happens if you forget the PIN or change phones. Import a harmless test photo, then confirm the original in Photos is deleted or kept as you expect, and try the app's backup and restore before trusting it with anything important.
Among the 167 photo vaults in our snapshot with a label, 46% declare tracking, 54% collect data linked to you and 28% say they collect nothing. Photo Vault Darkbox lists 1 data type, fewer than the average of 2.5 for this group.
Photo and video apps usually request access to your photo library. iOS lets you share only selected photos, which keeps the rest of the library — and its location metadata — away from the app.

Lock Photo Vault Darkbox behind Face ID
- Find Photo Vault Darkbox on your Home Screen or in App Library.
- Touch and hold the icon until the quick-actions menu opens.
- Tap Require Face ID (or Require Touch ID / Require Passcode, depending on your iPhone).
- Tap Require Face ID again to confirm. Photo Vault Darkbox now asks for authentication every time it opens.
The lock is an iPhone feature, so it works whether or not Photo Vault Darkbox has a passcode of its own. It does not change what the app sends to its developer.

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 Photo Vault Darkbox 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.
