Privacy policy

Zero2Bull is responsible for the personal data collected, under the Israeli Protection of Privacy Law, 1981.

• Account: display name, email, preferred language.
• Learning profile: your onboarding answers.
• Confirmations: when and which version of the terms and disclosure you accepted.
• Activity: lesson progress, scores, XP, streaks, simulator and competition activity.
• Mentor questions and answers.
• Feedback: messages you send us through the feedback form, with the page they were sent from.
• Invitations: if you joined through a friend's link, the link between the two accounts. The friend only sees how many people joined, never who.
• Reminders: a technical device identifier, if you enable notifications.
• Technical: strictly necessary sign-in cookies only. No advertising cookies. Anonymous, aggregated usage statistics (page views and loading speed) are collected without cookies and without identifying you.

Values you enter in lesson calculators are not saved or sent — the calculation happens on your device only.

To run and personalise the Service, save your progress, run competitions and leagues, send reminders you asked for, improve content, keep the Service secure and record legal confirmations.

We don't sell personal data. Service providers acting for us: Supabase (database and sign-in), our hosting provider (e.g. Vercel, including anonymous usage statistics), Google (only if you choose to sign in with a Google account: name, email and account ID). Leaderboards show your display name to other users.

Some providers store or process data outside Israel, in line with the applicable transfer regulations.

You may access, correct and request deletion of your data. Deleting your account from the profile page deletes all your data.

We keep data while your account is active and delete it when you delete the account (except what the law requires us to keep, such as invoices). Data is protected with encryption in transit, access controls and database-level permissions.

The Service is for ages 18+; users aged 16–18 need the consent of a parent or guardian.

We'll update this policy from time to time and announce material changes.
