About OpenTaskr
We believe planning together shouldn't mean surrendering your privacy. OpenTaskr is our answer: a task platform designed so that even its operator cannot read your messages. The work is shared — and only the work. Everything else is sealed.
Privacy by physics
Zero-knowledge, end-to-end encryption is the architecture — not a settings toggle. Your content is sealed in your browser before the server ever sees it.
The operator is blind too
Whoever runs the server — us or you — holds ciphertext and counters. Messages, plans and names are unreadable by design, so there is nothing to leak, sell or hand over.
Done, calmly
Deadlines that breathe, a completion ceremony led by the task owner, and analytics without surveillance. Productivity without the pressure.
The story so far
OpenTaskr began life as Taskr — a calm, Notion-style task manager whose logo was a lowercase “t” shaped like a checkmark. When the project went the move to OpenTaskr marks its next chapter — the same calm check, with the promise baked into the architecture: work can be shared freely, while the data itself stays sealed.
The mark tells the story in one glance — the check, planted on the line: the line is the shared list anyone can join; the check is the deed, done and on the record, cryptographically out of everyone else's reach.
And because calm software deserves a face, there's Loop — the open ring who keeps the door for finished things (and waves a lot).
What zero-knowledge actually means here
- Every task, comment, notification, org and project name is encrypted in your browser with AES-256-GCM.
- Your password derives your keys on your device — the server verifies login without ever holding them.
- Admins and operators see ciphertext, identifiers and counters. Not titles. Not plans.
- Forgot your password? The data is genuinely gone — there is no back door to lose.
Nothing to read, nothing to leak
Whoever runs the server — this instance or your own — holds ciphertext and counters. Not messages. Not plans. Not names. That's not a policy you have to trust; it's how the design works.
