We handle them. Every user — partner, model, or member — has the right to delete their account, request the personal data we hold about them, and opt out of marketing and personalization. When a request comes in, we act on it under GDPR and EU regulation.
We are the data controller for this, so nothing is required from white-label owners.
The exception is data you collect yourself. If you gather personal information through your own channels, you're the controller for that data and responsible for handling those requests.
