Small software that respects people.
Tidemark makes focused, open-source applications: no lock-in, and nothing you don’t need. Each one does a single job well and runs where you want it to.
Apps
The Tidemark family.
Every app is open source, and each has its own home under this site.

Principles
How we build.
- Private by design. We collect only what an app needs to do its job, and we say plainly what that is.
- Open source. The code is public and MIT licensed, so you can read it, run it and change it.
- Yours to keep. Your data stays where you put it, and you can always export it.
- Calm and small. Few features, done carefully, with no growth tricks.
