Louk builds calm apps that run on your device. No tracking, no copy of your data on a server — your data is yours, and it stays that way.
Not features to toggle — the ground rules. They don't change from one app to the next.
Everything you create stays with you. Our apps work offline and keep your data with you. Your data isn't in a cloud we can read — it's on your device, where it belongs.
No analytics, no tracking, no ads. There's no data to collect because we collect none. Privacy isn't a setting you find later; it's the shape of the thing.
Gentle by default — no guilt, no streak-shaming, no notifications fighting for your attention. Just enough to help you move forward, and then out of your way.
Everything lives on your device. What you track, write, and build lives where you made it. Our apps work offline and keep your data on your device — it stays in your hands.
Nothing is collected. No analytics, no tracking, no ads. There's no copy of your data on our side. Your privacy isn't a promise we make — it's how the apps are built.
Notifications are yours to set. Reminders happen only when you ask for them, at the times you choose. No nudges you didn't want, no pulling you back. The app stays quiet until you decide otherwise.
A good tool does its job and gets out of your way. That's the whole idea — calm, private, and entirely yours.
— Louk, calm, private, on your device
We'd rather build a few things well than many things fast.
Build the good habits you want — and quit the ones you don't. A calm way to keep going, one day at a time.
More on the way. New apps, same three commitments — local, private, calm. No newsletter, no waitlist; just check back.
The research points to about two months, with a huge range — and missing a day barely matters.
