A daily check-in that adds up

Small days compound.

Every night, mark the day green or red. Good days add points, lazy days take them away, and one line shows where you're heading.

Works on your phone and laptop. Nothing to install.

Four marks. One honest score.

Before you sleep, pick the one that's true. That's the whole habit.

MissedDidn't finish, but there was a real reason.

Missed, no excuseNo reason. You just didn't.

Streak apps reset you to zero. Here your score keeps what you built, so a slip is a dip, not a restart.

A real reason costs nothing. No reason costs a point. You'll know which one it was.

Mark from bed on your phone, look at the graph on your laptop. You stay signed in.

Free. Your first mark takes one tap.

Who runs it: Compounding is a small independent project. For questions, data requests or complaints, email hello@compounding.today.
What's stored: your first name, email, a hashed password (never the password itself) and your daily marks. That's it.
Why: only to run your account and show you your own data.
Cookies: one cookie keeps you signed in, and your browser remembers a couple of chart settings. No tracking cookies, so no cookie banner.
What's not: no ads, no analytics, no trackers. Your data is never sold or shared.
Where: the app and database run on Cloudflare, whose servers may be outside the EU. Sign-up uses Cloudflare Turnstile to stop bots. A nightly backup is kept for up to 90 days.
Your rights: export your marks, change your name or delete your account any time from the dashboard. Deleting removes everything right away; it drops out of the backups within 90 days. You can also ask for a copy or correction of your data, and complain to the Dutch data protection authority (Autoriteit Persoonsgegevens).
Age: you need to be 16 or older to sign up.
