The developer states that no data is collected from this app.
On the label, yes. DS One-Video Library&Player's developer reports that it collects no data, which puts it among the 24% of cloud storage apps we checked with a "Data Not Collected" label. That is a self-declared statement, not an audit, and it does not cover data processed only on your device.

Did DS One-Video Library&Player ask for something?
Pick the permission prompt you saw. We compare it with what DS One-Video Library&Player's developer declared.
Location is not on DS One-Video Library&Player'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 DS One-Video Library&Player'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 DS One-Video Library&Player'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.
DS One-Video Library&Player declares no tracking, so a tracking prompt would contradict its label. Decline it, and consider reporting the mismatch to Apple.
Health & Fitness is not on DS One-Video Library&Player'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 DS One-Video Library&Player's label means for you
“Data Not Collected” is the cleanest result a label can show. It means the developer states that no data leaves your iPhone in a way the developer or its partners can access for longer than needed to handle a request. Data processed only on your device does not count as collected, so DS One-Video Library&Player can still read files or photos you open in it.
The statement is the developer's own. Apple reviews apps but does not audit every label, and analytics or crash-reporting libraries added later can make a label out of date. If DS One-Video Library&Player asks you to create an account, upload files or allow tracking, that would not match a no-collection label — and is worth noticing.
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. DS One-Video Library&Player lists 0 data types, fewer than the average of 3.3 for this group.
Utilities range from calculators to VPNs, so their labels vary more than any other category. A simple tool that collects identifiers and usage data for tracking is a sign of advertising SDKs.

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 DS One-Video Library&Player 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.
