Last updated: July 18, 2026
Information we process
- Your name, email address, and verification status when you create an account
- Your name, email address, and profile image shared by Google or GitHub when you sign in with those providers
- IP address, browser information, and session records for account security
- Effects you add to your library

Purposes of processing
We process information to provide account services, maintain security, resolve errors, remember preferences, measure service performance, and meet legal obligations. The service is free and we do not collect payment information.
Service providers
Limited information may be shared with providers for hosting, email, authentication, analytics, and advertising. When Google advertising products are enabled, Google may use cookies or similar technologies to serve and measure ads. Review the Google partner-sites explanation for more information.
Retention and security
Data is retained only as long as necessary to provide the service, maintain security, resolve disputes, and meet legal obligations. We use access controls, encryption, and session-security measures to reduce unauthorized access, though no internet transmission can be guaranteed completely secure.
Your rights
Send requests to access, correct, delete, or object to processing of your data to iletisim@librarycss.com. Identity verification may be required depending on the request.
Children's privacy
The service is not intended to knowingly collect personal information from people under 18. Contact us if you believe such data has been processed.
Changes
We may update this policy as the service or applicable law changes. The current version and revision date are published on this page.
