Criteria
- Yes

No
No trackers or telemetry Weight 3 of 3
Are the website and apps free of third-party trackers, with any analytics anonymous and any telemetry off by default?
No third-party analytics, but the app downloads the sponsor list at every launch, and the vendor uses that request to count launches and daily users by country, city and app version. This cannot be turned off. Daily sponsor view totals are also sent unless turned off in Settings.
-
No
No ads or data sales Weight 2 of 3
Is the product funded without advertising, ad targeting or selling user data?
Funded by a sponsor banner in the app. By default the banner is chosen from interests the app infers from folder names and sizes after a scan. The matching happens on the device and can be turned off in Settings.
-
No
Independent audit Weight 2 of 3
Has an independent security or privacy audit been published within the last three years?
No independent audit is published.
-
Partial
Works offline Weight 2 of 3
Does the app scan and show disk usage without contacting the internet?
Scans run locally and file names are not uploaded. The app fetches the sponsor list at launch and checks GitHub for updates by default. The update check can be turned off; the sponsor list request cannot.
-
Yes
No account needed Weight 1 of 3
Can the app be used without an account or registering an email address?
No account or sign-in. Scanning cloud storage uses the user's own rclone or SSH setup.
