Privacy Notice
Effective date: February 25, 2026
This Privacy Notice explains how CineMetrics ("we", "us", "our") collects, uses, stores, and deletes personal data when you use this Service.
Independent Service; No Letterboxd Affiliation
This Service is independent and is not affiliated with, endorsed by, or sponsored by Letterboxd.
We process only user-submitted data and user-authorized RSS refresh data under your consent choices.
Data We Collect
We may collect and store:
1. Account data: account username, linked Letterboxd username, password hash, role, and consent timestamps.
2. Film data: uploaded export content, normalized film logs, and derived analytics for community statistics.
3. Preferences: RSS refresh opt-in/opt-out status and update timestamps.
4. Security and operations data: rate-limit events, auth events, and basic request metadata used for abuse prevention and troubleshooting.
How We Collect Data
We collect data when you register, upload your export file, change account settings, and use account-related endpoints.
Weekly RSS refresh runs only for members who explicitly opt in.
No scraping fallback is used for account ingestion.
How We Use Data
We use your data to:
1. Operate your account and authentication session.
2. Build member-level and community-level film analytics.
3. Run optional weekly RSS refresh for opted-in members.
4. Maintain security, prevent abuse, and monitor service health.
Data Sharing
We do not sell personal data.
We may share limited data only with service infrastructure providers needed to run this site (for example hosting/monitoring), or when required by law.
Data Retention and Deletion
We retain account and analytics data while your account is active, unless deletion is requested.
You can delete your account data from the Account page. Deletion removes your uploaded logs and disables RSS refresh.
Your Choices and Rights
You can access and update your account information, disable RSS refresh, and request deletion of your account data.
Security
We apply technical and organizational safeguards including access controls, rate limiting, request validation, and security event monitoring.
Changes to This Notice
We may update this Privacy Notice. The latest version is posted here with an updated effective date.
