Controller: "Replace GbR", "replace@di-o.de".
Twitch (sign-in), Streamlabs and/or TipeeeStream (your events, at your instruction), Stripe (payment processing, including the card details this service never sees), and the hosting provider running this server. No advertising, no analytics that identify you, no sale of data.
Until you delete your account, which you can do at any moment from the panel: it removes your profiles, credentials, progress and event log immediately. Payment records are kept as long as tax law requires.
Access, rectification, erasure, restriction, portability and objection under the GDPR, and a right to complain to a supervisory authority. Write to "replace@di-o.de".
One cookie, holding your signed-in session. It is strictly necessary for the service to work and is not used for anything else.
