Privacy Policy

Last updated: July 19, 2026

Habit Stacker (“the app”, “we”) is provided at www.habitstackerapp.com. This policy describes what information we collect and how we use it.

Information we collect

• Account information — email address and authentication data managed by Supabase Auth when you sign up or log in.
• Habit data — habit names, start dates, and related fields you enter in the app.
• Technical data — standard server logs (e.g. IP address, browser type) that may be collected by our hosting provider.

How we use information

We use your account and habit data only to operate Habit Stacker: authenticate you, store your habits, and show your streaks. We do not sell your personal information or use it for advertising.

Where data is stored

Account and habit data are stored in our Supabase project (hosted database and auth). The website and API are hosted by our application host.

Account deletion

You can delete your account yourself while logged in via Delete Account. That removes your Auth user and habit data tied to your email. You can also contact us using the method published on www.habitstackerapp.com.
