Privacy policy
Pustok keeps only what learning needs. No data is ever sold to advertisers.
Last updated: 5 October 2026
What we keep
- For the account: a phone number or email, the learner's name, class, version and avatar.
- Learning progress: lessons finished, practice results, study time and streaks.
- Text, voice notes and notebook photos sent to the study buddy, only to answer the question.
How we use it
- To show lessons, practice and the parent report.
- Voice notes and notebook photos are used only to answer questions, never for advertising.
- Anonymous totals help us improve lessons.
Keeping children's data safe
- Up to class 5, the account, purchases and settings stay with a parent.
- A child's data is never sold or rented to advertisers or other third parties.
- Other users cannot search for a child's profile. Leagues show only a nickname and an avatar.
Your rights
- Write to us at any time to see, correct or delete your data or account.
- Deleting an account also deletes its learning data, voice notes and photos.
Security
- All data travels over encrypted connections. Only team members who need it for their work can see it.
