Who we are
The CTDS app is operated by Cech Terra de Selinan, občianske združenie, Antona Bernoláka 2180/58, 010 01 Žilina, IČO 37801457 („the club“). The club is the data controller under the GDPR.
The app is an internal tool for recording training attendance. It is not intended for the general public. Accounts are created by the club for its members only.
What data we process and why
- Login details of members with an account.
- Member details: name, surname, email, payment variable symbol and NFC tag identifier.
- Profile details you can view and edit in the app: phone number, date of birth, address and IBAN.
- Attendance records: who attended which training and when.
- Crash reports and anonymous usage statistics.
We use this data to run club membership, record training attendance and handle payments between you and the club, based on your membership in the club (GDPR Art. 6(1)(b)) and the club’s legitimate interest in a working app (Art. 6(1)(f)). When you change your email address, we send a verification email to the new address.
Storage and sharing
Member and attendance data is stored only on the club’s server, not on your device. Members with an app account can see other members‘ email addresses to contact each other within the club. Your phone number, date of birth, address and IBAN are not shown to other members; only you and the club’s administrators can see them.
Crash reports and usage statistics are processed by Google Firebase, possibly outside the EU under the EU Standard Contractual Clauses, which protects them to the same standard as this policy. We do not sell personal data or share it with anyone else, except where the law requires it.
We keep the data for the duration of your membership and afterwards only as long as the law requires.
Your rights
You have the right to access, correct or delete your data, to restrict or object to its processing, and to receive it in a portable format. You can view and correct your profile details in the app under Settings → My profile.
You can delete your account directly in the app under Settings → My profile → Delete account. Deletion is permanent and cannot be undone. You can also ask the club to delete your account at terradeselinan@gmail.com. For any other request, contact us at the same address.
You can also lodge a complaint with the Office for Personal Data Protection of the Slovak Republic, dataprotection.gov.sk.
