KM12 Collective ("we", "us"), Korfmakersstraat 12, 3026 XH Rotterdam, is the data controller for the personal data described below, collected through km12.nl.
Newsletter emails are processed with your consent, given when you sign up. Contact form and artist account data are processed to respond to you and to run the site, which are our legitimate interests as a small collective.
We use third-party service providers to run this site: Supabase (database, file storage, and account logins), Vercel (hosting), MailerLite (newsletter), and Resend (contact form emails). These providers process data on our behalf under their own data processing agreements.
Under the GDPR, you can ask to access, correct, or delete your personal data, or object to how we use it. To exercise any of these rights, email us at info@km12.nl. You can also lodge a complaint with the Dutch Data Protection Authority (Autoriteit Persoonsgegevens).
We keep contact form messages only as long as needed to handle your enquiry. Newsletter addresses are kept until you unsubscribe. Artist account data is kept for as long as the account is active with KM12 Collective.
