Privacy Policy
Last updated: September 2026
1. What data we collect
- Account data: name, email, password (stored encrypted), phone, and date of birth if you provide them.
- Training data: routines, sets, loads, personal records, attendance, and check-ins.
- Membership data: contracted plan, class balance, payment history (we don't store card numbers — Mercado Pago processes those directly).
- Device identifier for push notifications (Firebase Cloud Messaging token), if you enable notifications.
- Basic technical usage data (e.g. server errors) so we can keep the platform running.
2. What we use it for
- So you can use the app's features: train, book classes, check in, view your progress.
- So the Gym you belong to can manage your membership and communicate with you.
- To send you relevant notifications (class reminders, membership expiration, achievements) — you can always turn them off.
- For Zezen's gamification system (level, XP, achievements) — this is Zezen's own layer, not the Gym's.
3. Who we share data with
- The Gym you belong to: your coach/owner/staff sees your training and membership data within that gym — not from other gyms where you also train.
- Mercado Pago: if you pay for a plan online, your payment data is processed directly by Mercado Pago under its own privacy policy — Zezen only receives payment confirmation, never your card data.
- Firebase (Google): to be able to send you push notifications, if you enable them.
We do not sell your personal data to third parties for advertising purposes.
4. How long we keep your data
As long as your account is active. If you ask us to delete it, we erase your personal data except what we're required to keep for payment/tax records.
5. Your rights
You can ask us at any time to access, correct, or delete your personal data by writing to us at appzezen@gmail.com.
6. Cookies and local storage
We use a strictly necessary session cookie to keep you logged in. We don't use third-party advertising tracking cookies.
