USB Disk SE's developer reports using location, identifiers, usage data, diagnostics to track you across other companies' apps and websites.
Did USB Disk SE ask for something?
Pick the permission prompt you saw. We compare it with what USB Disk SE's developer declared.
USB Disk SE lists Location on its label, including for tracking. Choose While Using and turn off Precise Location if the feature works without it.
User Content is not on USB Disk SE'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 USB Disk SE'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.
USB Disk SE 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 USB Disk SE'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 USB Disk SE collects, explained
| Data type | What it covers | Where to limit it |
|---|---|---|
| LocationSensitiveUsed to track youLinked 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. |
| IdentifiersUsed to track youLinked 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 DataUsed to track youLinked to youNot 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. |
| DiagnosticsUsed to track youLinked to youNot 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. |
What USB Disk SE's label means for you
USB Disk SE's label has 4 types under “Data Used to Track You”, 4 types under “Data Linked to You”, 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.
Tracking is the declaration that most separates apps. It means location, identifiers, usage data, diagnostics from USB Disk SE 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.
The items that deserve the most attention are location. Location history reveals home, work and routines. Precise location deserves the most scrutiny.
Cloud storage apps exist to move your files off the phone, so collecting user content is expected. What differs is encryption, sharing defaults and what the provider can read. Review automatic camera upload, shared-link expiry and whether client-side encryption is available.
Among the 170 cloud storage apps in our snapshot with a label, 29% declare tracking, 64% collect data linked to you and 24% say they collect nothing. USB Disk SE lists 4 data types, about the same as the average of 3.3 for this group.
Productivity apps tend to collect the work you do in them — documents, notes and files — so User Content is common. The question is whether it syncs to the developer's servers and how it is protected there.
Settings to check for USB Disk SE
- 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
Location
Settings › Privacy & Security › Location Services › USB Disk SE. Choose While Using or Never, and switch off Precise Location if a city-level answer is enough.
- 3
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.

Does USB Disk SE track you?
Location, identifiers, usage data and diagnostics. Apple defines tracking as linking data from this app with data from other companies' apps, websites or offline sources for targeted advertising or ad measurement, or sharing it with a data broker.

Lock USB Disk SE behind Face ID
- Find USB Disk SE 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. USB Disk SE now asks for authentication every time it opens.
The lock is an iPhone feature, so it works whether or not USB Disk SE 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 USB Disk SE 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.
