2. Using the website without an account

You can use the whole site without signing in. We do not use advertising, tracking or analytics cookies. When you visit, our hosting provider processes technical data (IP address, date and time, requested page, browser type) in server logs to deliver the site and keep it secure (Art. 6 (1) (f) GDPR). The site is hosted by Vercel Inc., USA (EU data transfers are covered by standard contractual clauses).

If you set up “My profile” or save items, your choices (instrument, stage, saved schools and competitions) are stored only in your browser (local storage) on your device. They are not sent to us. You can delete them at any time by clearing the profile or your browser data.

3. Optional account

If you choose to sign in, we process: your e-mail address (to send you a one-time sign-in link and identify your account), your profile (instrument, stage, what you are looking for) and your saved schools and competitions. Purpose: to keep these settings in sync across your devices. Legal basis: Art. 6 (1) (b) GDPR (providing the account you asked for). If you set a password, Supabase stores a password hash for authentication. Sign-in links work once and expire. When you sign in, our processor also records technical data such as your IP address and the time of sign-in, to keep accounts secure (Art. 6 (1) (f) GDPR).

Data is stored with our processor Supabase (database and authentication) in a data centre in the EU (Frankfurt, Germany). Sign-in e-mails are sent through our processor Resend (Resend, Inc., USA) from its EU region (Ireland); for this, Resend receives your e-mail address and the sign-in e-mail. Transfers to the USA are covered by standard contractual clauses. We do not sell data and do not use it for advertising. We send you e-mail only for signing in.

Retention and deletion: your data is kept until you delete your account. You can delete the account yourself at any time under “My profile” → “Delete account”; your profile and saved items are then removed together with it.

4. Your rights

You have the right of access, rectification, erasure, restriction, data portability and objection (Art. 15–21 GDPR), and the right to withdraw consent given. Contact us at the e-mail address above. You also have the right to lodge a complaint with a data protection supervisory authority.

5. External links

We link to the websites of schools and competitions. Once you follow a link, the privacy policy of that website applies.

6. Teachers and prize winners named on this site

School pages list teachers with their name, position, subjects and a link to their official profile, and competition pages list past prize winners. We do not publish the names of prize winners in under-18 (youth) categories, nor of winners whose category the source does not state when a competition also has under-18 categories; for these we show only category, age range and prize. Ensembles are listed by ensemble name only. We take this information only from the official websites of the schools and competitions, where it is already published. We do not publish e-mail addresses or phone numbers. Purpose: to help applicants find out who teaches a subject and what a competition has achieved. Legal basis: Art. 6 (1) (f) GDPR (legitimate interest in providing this public information). If you are named and want an entry corrected or removed, write to the e-mail address above and we will do so promptly; you also have the right to object (Art. 21 GDPR).
