Why on-device
Most apps of this kind start with an account. It's the default: you sign up, your data lands on a server, and from then on the app is a window onto something you don't hold. It works, and it makes sync easy — but it also means a company sits between you and your own notes, habits, or plans.
Louk starts from the other end. The data lives on your device and stays there. There's no server to breach, no database to sell, no policy change that can quietly widen what gets collected. Not because we're especially trustworthy — because there's nothing on our side to trust us with.
What "calm" means here
Habit apps in particular have a tendency to shout. Streak-shaming, red badges, daily pushes engineered to pull you back in — the mechanics of engagement, borrowed from social apps and pointed at self-improvement.
That's a design choice, not a necessity. Louk's apps notify you when you asked to be notified, and stay quiet otherwise. A missed day is a missed day, not a failure that needs a red dot. The goal is a tool you reach for, not one that reaches for you.
How they're paid for
No ads, no subscriptions, no data as a side business. When an app has something worth charging for, it's a one-time purchase: you buy it once and keep it.
This is only possible because of the first decision. There are no servers to run each month, so there's no recurring cost that needs a recurring payment to justify it. The economics and the privacy stance hold each other up.
Made slowly, on purpose
Louk would rather ship a few things well than many things quickly. Every app is expected to still make sense years from now, which rules out chasing whatever is current this quarter.
In practice that means fewer releases, and each one narrower than it could have been. Yolmira, a habit tracker for building good habits and quitting bad ones, is the first. Others will follow when they're ready.
