Android suite
Seren (SEH-ren)
Everyone deserves free, high-quality apps that don’t track them.
Seren is Welsh for star — a small, steady light nobody owns. The suite is SSH, a text editor, an authenticator, and a file manager: open source, no ads, no analytics, and data that stays on your device. Quiet tools, carefully made, meant to feel like they belong to you.
What we believe
Good software shouldn’t cost your privacy, or hide behind a paywall. These four promises are the brand — everything else is there to keep them.
No ads, no tracking
No ad SDKs, no analytics, no crash reporters, no network calls you did not ask for.
Open source
Apache License 2.0. Full source on GitHub. Builds with ./gradlew assembleRelease.
Yours, on your device
Data stays local. Secrets use a hardware-backed key. Nothing sensitive goes into cloud backup.
The apps
Everyday tools, built to the same standard you’d expect from something you paid for — without the tracking, the upsell, or the feeling that you’re the product.
Ready for daily use
Seren SSH
A modern SSH client with a custom terminal, jump hosts, port forwarding, SFTP, and sessions kept alive in the background.
