Data Deletion
You can request deletion of your account and associated personal data by emailing hello@quickmark.co. We may retain limited records where required for security, legal, or fraud-prevention reasons.
Children's Privacy
QuickMark is intended for learners using it with appropriate permission and supervision. Email hello@quickmark.co if you believe a child has provided personal information that should be removed.
Data Security
We use access controls, secure connections, and reasonable operational safeguards. No internet service can promise absolute security, so protect your account credentials and tell us about suspected misuse.
