What we collect, why, and your choices.
What we store
If you sign in with Google, we receive your name, email address and profile picture. We also save what you create in the app: bookmarks, lesson progress, preferences and private notes. Please don't put sensitive personal details in your notes.
How it is used
Only to sign you in and to save and show your notes, bookmarks and progress. We do not sell your information or use it for advertising.
YouTube, Google and cookies
Lessons play through YouTube's embedded player, and sign-in and storage use Google and Firebase. These services may set cookies or collect data under their own privacy policies. The app itself only stores small preferences on your device, such as your sign-in and your choices.
Children
The app is for students. Younger learners should use it with a parent or guardian.
Your choices
You can edit or delete your notes and bookmarks, or ask us to delete your account and data.
