Privacy Policy
Last updated 22 August 2026 · Applies to DustFox for iPhone and iPad
The short version: DustFox does not collect any data. Your photos and videos are read on your device, compared on your device, and never sent anywhere. There is no account, no analytics, and no tracking.
1. Who is responsible
DustFox is developed and published by Furkan Kaya (“we”, “us”). If you have a question about this policy, write to support@dustfox.app.
2. Data we collect
None. DustFox contains no analytics SDK, no crash-reporting SDK, no advertising SDK, and no third-party libraries of any kind. The app makes no network requests of its own.
Concretely, we do not collect, receive, store, or have any access to:
- your photos, videos, or any content derived from them;
- your name, email address, phone number, or any account identifier;
- your device identifiers, advertising identifier, or location;
- usage statistics, session logs, or crash reports.
3. How your photo library is used
When you grant photo access, DustFox reads your library to find duplicates, blurry shots, large files and the other categories it offers. All of this — fingerprinting, comparison, scoring, compression and re-encoding — happens on your device, using Apple’s frameworks. Scanning works with the network switched off, which is the simplest proof that nothing is being uploaded.
DustFox only modifies your library when you ask it to. Deletions are performed through Apple Photos, which moves the items to the Recently Deleted album where they remain recoverable for 30 days.
4. Data stored on your device
DustFox keeps a small amount of state locally so the app behaves sensibly between launches: your settings, your compression preferences, a record of which frames you chose to keep, and a history of how much space you have reclaimed. This lives in the app’s own storage on your device. It is included in your iPhone backup if you back up your device, it is removed when you delete the app, and it is never transmitted to us.
5. Purchases
DustFox Pro is a one-time in-app purchase processed entirely by Apple through the App Store. We never see your payment details. Apple tells the app one thing only: whether this Apple Account is entitled to Pro. We receive no name, email address, or card information, and we cannot identify individual buyers.
Apple’s own handling of your purchase is governed by Apple’s Privacy Policy.
6. Network use
The app connects to the internet for exactly two operations, both initiated by you and both handled by Apple’s StoreKit framework: buying Pro, and restoring a previous purchase. There is no other network activity.
7. System APIs that require a declared reason
Apple requires apps to declare why they use certain system APIs. DustFox declares two, and both are used only to make the app work:
- Disk space — to draw the storage bar showing how full your device is.
- User defaults — to store your own settings, in the app’s own space.
Neither is used for tracking, and no information from either leaves the device.
8. Children
DustFox is not directed at children and collects no data from anyone, including children.
9. Your rights
Regulations such as the GDPR and the CCPA give you rights over personal data a company holds about you — access, correction, deletion, portability, and objection. Because we hold no personal data about you whatsoever, there is nothing for us to retrieve, correct, export, or erase. If you want to remove everything DustFox has stored, delete the app; iOS removes its local storage with it.
We do not sell or share personal information, because we have none.
10. Changes to this policy
If a future version of DustFox ever changes what it does with data, this page will be updated before that version ships, and the date at the top will change. A version that collected anything would also have to say so in its App Store privacy label.
