Privacy policy

We store account names, email addresses, authentication sessions, private collections and support messages. Viewing progress is no longer collected. Historical progress records, if any, remain available in account exports until account deletion. Cloudflare operates the application, database and private temporary storage.

Video playback and cover images come from the original platforms. Loading an embed may transmit your IP address and browser information to that platform. Its privacy rules apply.

AI analysis is disabled at launch. When enabled, Qwen receives short-lived video segments for transcription and learning summaries. Media is temporary, excluded from backups and deleted after processing; expired objects have a storage lifecycle fallback. Published text materials and source metadata remain in the catalog.

When configured, Google Analytics starts automatically without a consent prompt. We disable advertising signals, respect DNT/GPC and exclude email addresses, search terms, transcripts and collection names from analytics.

You can export or delete your account from Account. Deletion removes private collections and progress. Operational review and security records may remain where needed for abuse prevention. Contact support@math-video.com
