Zero-knowledge encryption
Every entry is sealed with AES-256-GCM + Argon2id before it touches storage. We have no key, no copy, no access.
Privacy-first productivity
One private app for habits, todos, notes, and the moments in between.
Encrypted on your device with AES-256-GCM + Argon2id.
Even Singletick can't read it. Nobody can.
Habits, todos, notes, pledges, mood, focus, secrets — and a web companion that respects the same privacy charter.
Every entry is sealed with AES-256-GCM + Argon2id before it touches storage. We have no key, no copy, no access.
Encrypted blobs go to your Google Drive or iCloud. Even your cloud provider can’t read them.
Edit habits and todos from your laptop. The phone is the trusted device — pair with a short code, no IP addresses.
See how mood, sleep, and habits move together. On your device. We never see the result.
Commit to a goal with a friendly penalty if you slip — a public admission, a journal entry, a donation hint.
One-tap habit completion from the home screen. Streak count on the lock screen and Dynamic Island.
A separate PIN seals your most personal notes. Auto-locks the moment you switch apps.
A handful of things only Singletick gets right — alongside the table-stakes everyone ships.
