Small, useful Android apps that don't want your data.
NavoBytes is the studio behind File Manager Ultra and Navo AntiVirus & Security. Both are free to download, neither asks you to create an account, and the work they do happens on your device rather than on our servers.
Apps
Published on Google Play. Each one has its own page, including its own privacy policy.
File Manager Ultra
Browse, organise and clean up your phone's storage. Find duplicates and leftovers, see what is eating space, transfer files without a cable, and keep private files behind a PIN.
Navo AntiVirus & Security
Scan your installed apps and storage for threats, review what was found, remove what you don't want, and clear junk files and background battery drain in the same place.
More apps are in development. Anything that is not listed above is not published yet — we would rather show you nothing than link you to a store page that doesn't exist.
How we build
Most "free" utilities pay for themselves with your data. We would rather be honest about the trade, so here is what ours actually is.
- On-device by default. Where a job can be done on your phone — scanning, cleaning, organising, comparing files — it is done there, not uploaded.
- No account walls. There is nothing to sign up for. Connecting a cloud drive is optional, and you sign in with the provider directly, not with us.
- Ads, declared up front. The free versions are funded by advertising. Paid upgrades remove the limits and the ads; where we offer a rewarded video, watching it unlocks ad-free time without paying.
- Claims you can check. We don't write "military-grade encryption" or "100% safe". If a feature works in a specific way, we describe that way — including its limits.
- Analytics you can refuse. Usage analytics start switched off and only run if you accept the consent prompt.
Support
Found a bug, hit a billing problem, or want a feature? Email us. A real person reads it, and for anything account-related we may ask for the app version shown in the app's settings.

Privacy documents, per app
Every app has its own policy because every app handles different things. Nothing is shared between them.
File Manager Ultra
Your files stay on your device. Ad ID, consent-gated analytics and crash reports are the only data that leaves it — described in full.
Navo AntiVirus & Security
Our security app. Its privacy policy is published in its own Play listing; a page on this site is in preparation.
