You can ask to access your personal data, correct it, erase it, restrict processing or object to certain processing. You can request portable data or withdraw consent when those rights apply. Open a support ticket and clearly say that it concerns your data rights. We may verify your identity when necessary. We aim to respond within one month; the law may allow an extension for complex or numerous requests, and we will tell you if that applies.
For an independent complaint, contact ANSPDCP. Read the official GDPR text on EUR-Lex.
