Privacy policy
Last updated 2026-11-11
This policy explains what personal data Hessen Flex Tennis Liga collects and why, under the EU General Data Protection Regulation (DSGVO) and the German BDSG. The controller is DataSci Consulting LLC, 4303 Potomac Highlands Cir, Triangle, VA 22172, USA (see the Impressum).
What we collect
- Account details: name, email address, phone or WhatsApp number, and a password (stored hashed).
- Playing details: your Leistungsklasse or self-assessed level, area, availability, optional profile photo and profile text.
- Match records: scores, disputes and strikes.
- Bookings and requests: coaching bookings and court-help requests.
- Payment records: the amount, status and transfer reference of your season entry. The league's bank statement shows the account you paid from; we never ask for card details.
- Device details: a push-notification token, and crash reports with personal data removed.
- Location: only if you tap "near me" on the courts screen, and it is used on your phone and not stored by us.
Why we use it
To run the league (contract, Art. 6(1)(b) DSGVO): place you in a division, show standings, let you contact opponents and coaches, confirm payments and handle refunds; to send notifications you have agreed to (consent, Art. 6(1)(a)); to fix errors and keep the league fair (legitimate interest, Art. 6(1)(f)).
Who can see it
- Players in your division see your name, area and level, and your phone number if you are in the same division.
- A coach you book is told your name and the session time.
- League administrators see account and payment data to run the league.
Who we share it with
Our hosting provider (servers in Frankfurt am Main, Germany (Hostinger)), Expo, Apple and Google (delivering notifications, token only), our error-reporting and email providers, and the storage provider for profile photos. Providers outside the EU are used only under standard contractual clauses or an adequacy decision. We share only what each one needs.
How long we keep it
- Account data until you delete your account.
- Match results with your name removed after you delete your account.
- Bookings and court-help requests for 2 years.
- Payment records for as long as German tax law requires (up to 10 years).
- Crash reports for 90 days.
Your rights
You can see and correct your profile in the app, delete your account in Settings, and ask us for a copy of your data, to correct or erase it, to restrict or object to its use, or to receive it in a portable format (Art. 15 to 21 DSGVO). You can complain to a supervisory authority; for Hessen that is the Hessischer Beauftragter für Datenschutz und Informationsfreiheit (HBDI).
Children
The league is for adults aged 18 and over.
