This explains what collects when you visit this site or buy Winter Arc 90.
Your habits, journal, weight and other entries in the app are saved only in your own browser. They are not sent to us.
When you unlock the app, it sends your app code and a random ID made on that device to our server, and checks again about once a day. We use this only to keep each code to 3 devices and to switch it off after a refund. The ID says nothing about you or your phone.
Razorpay (payments), Cloudflare (hosting), Google Fonts (fonts) and Meta (ads, only if the pixel is on). We don't sell your data.
Email to ask for a copy of your data, or to have it corrected or deleted, unless the law needs us to keep it. You can block cookies in your browser settings. We keep sale records for as long as tax and accounting rules require.
