    Addendum: the voleypro.com Website

    In addition to the VoleyPro mobile app, this document also applies to the voleypro.com website and web app. You sign in with the same account on the web, and the data listed above is processed on the same infrastructure for the same purposes.

    Specific to the website, the following is also processed:

    • Server access logs: IP address, browser and device information (user agent), the page requested, and the date and time. These logs are kept for a limited period, solely to keep the service secure, prevent misuse and diagnose errors, on the basis of legitimate interest (KVKK Art. 5/2-f). • Browser storage: The website does not use cookies. Your browser's local storage (localStorage) holds only your session tokens, your theme (dark/light) preference and your library view preference. None of it is used for advertising or tracking; session tokens are removed when you sign out, and you can clear all of it in your browser settings. • Sign in with Google: If you use this option you are redirected to Google's sign-in page, and with your consent Google shares your name, email address and Google account ID with VoleyPro. Google's own privacy policy applies to that step. This option is optional; you can also register with an email and password.

    The website contains no third-party analytics, advertising or tracking tools; fonts and images are also served from VoleyPro servers.
