Privacy

Short version: your students and payments never leave your device, and we do not track you.

Your lesson book

Students, lessons and payments are saved in this browser's local storage. They are never sent to us or anyone else. Backup files you save are yours; we never see them. Clearing your browser data deletes the book, so keep a backup.

What we count

• Which pages are visited, the website that sent you (only its name), and your device type.
• Your approximate location (country, region, city) as reported by our hosting provider. We do not store IP addresses.
• Unique visitors per day, using a code our server derives from your IP address and browser that changes every day. There are no cookies.
• That someone added a first student, logged a first lesson or saved a backup. Never names, amounts or any content.
