Verdict from the label
Not linked to you

Sup collects some data but says none of it is linked to your identity, and none is used for tracking.

Did Sup ask for something?

Pick the permission prompt you saw. We compare it with what Sup's developer declared.

Tap a prompt to compare it with the label.
Not on the label

Location is not on Sup'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.

Matches the label

Sup 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 Sup'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

Sup 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 Sup'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 Sup collects, explained

Data typeWhat it coversWhere to limit it
User ContentSensitiveNot linked 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 InfoNot linked 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.
IdentifiersNot linked to you An account ID, screen name, customer number or a device-level ID such as the advertising identifier. Settings › Privacy & Security › Tracking: turn off Allow Apps to Request to Track, or tap Ask App Not to Track when prompted.
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 Sup's label means for you

Sup'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 Sup'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 user content. This is the content you actually care about. Where it is stored, who can read it and how it is backed up matters more than any other line on the label.

Private-photo apps promise to keep pictures out of your main library. The label shows what leaves the phone; it cannot show whether the hiding is a real lock or just a separate folder. Check whether the app needs full Photos access or works with selected photos, and whether hidden items still appear in iCloud Photos.

Among the 85 private photo apps in our snapshot with a label, 51% declare tracking, 61% collect data linked to you and 18% say they collect nothing. Sup lists 5 data types, more than the average of 3.1 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 Sup

  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

    Contacts

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

  4. 4

    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.

  5. 5

    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.

  6. 6

    Notifications

    Settings › Notifications › Sup › Show Previews: When Unlocked keeps message and account details off the Lock Screen.

Cross-app tracking

Does Sup track you?

iOS 18 and later

Lock Sup behind Face ID

  1. Find Sup 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. Sup now asks for authentication every time it opens.

The lock is an iPhone feature, so it works whether or not Sup 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 Sup 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.

Quick quiz

True or false?

  1. Q1Sup's privacy label says it uses data to track you.
    Right.
    Not quite.

    False: there is no Data Used to Track You section on Sup's label.

  2. Q2Apple tests every app to confirm its privacy label is accurate.
    Right.
    Not quite.

    Labels are self-reported by developers. Apple can reject or remove apps that misrepresent practices, but it does not audit each label.

  3. Q3Sup collects User Content.
    Right.
    Not quite.

    True: User Content appears on its label, in the Not Linked to You section.

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

    It is collected and sent; the developer says it is de-identified rather than tied to your account or device.

  5. Q5Tapping “Ask App Not to Track” can stop an app from working.
    Right.
    Not quite.

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

Questions people ask

Sup privacy FAQ

Is Sup safe to use?
Based on its App Store privacy label, sup collects some data but says none of it is linked to your identity, and none is used for tracking. Whether that is acceptable depends on what you will store in it. The label is developer-reported, not an independent security test.
Does Sup track you?
No. Sup's label has no Data Used to Track You section.
What data does Sup collect?
User content, contact info, identifiers, usage data and diagnostics. None of it is linked to your identity.
Who makes Sup?
Young Human, LLC, according to the App Store. It was first released in June 2017 and the current version is 10.1.0.
Can I lock Sup with Face ID?
On iOS 18 or later, touch and hold Sup's icon and choose Require Face ID (or Touch ID / Passcode). This is an iPhone feature and works for most downloaded apps, whether or not the app has its own lock.
How does Sup compare with other private photo apps?
Across 85 private photo apps with labels in our snapshot, 51% declare tracking and 18% say they collect no data. Sup lists 5 data types against an average of 3.1.
Are my pictures stored only on this phone, or uploaded?
The privacy label cannot answer that. Look for it in Sup's privacy policy or support pages, linked from the App Store listing. Check whether the app needs full Photos access or works with selected photos, and whether hidden items still appear in iCloud Photos.
How do I delete my data from Sup?
Apps that let you create an account must also let you start account deletion from inside the app (an App Store rule since June 2022). Deleting the app from your iPhone alone does not delete data already sent to the developer.

For photos and documents you choose to keep apart from your main library, see VaultForYou.
