Privacy Policy

Concento ("the Service", https://concento.io) respects your privacy. This policy explains what data we collect, how we use it, and the rights you have.

1. Data we collect

• Account data: the email address and display name you provide at sign-up; if you sign in with Google, the name and avatar provided by Google.
• Reading data: books you add, reading status and progress, ratings, reviews, book-club comments, and follow relationships.
• Preferences: interface language and privacy switches, stored in your browser (localStorage) and your account.

We do not collect your real name, address, phone number, or any payment information.

2. Where your data lives

• Account and reading data are stored in Google Firebase (Authentication and Cloud Firestore).
• The site is served as static pages by GitHub Pages.
• Book covers and descriptions come from public sources (Google Books, Open Library); some cover images load through an image proxy (images.weserv.nl).

3. How we use your data

• To provide core features: shelf management, community ratings and reviews, reading-compatibility scores, and the activity feed.
• We never sell or rent your personal data, and we do not use it for advertising.

4. Public vs. private

• Your library is private by default; other users can browse it only after you explicitly enable "public library".
• Your ratings, reviews, and book-club comments are public content visible to all users; you can delete them at any time.

5. Cookies and local storage

The Service uses browser localStorage for language preference and sign-in state (managed by Firebase). We do not use third-party tracking cookies.

6. Your rights

• You can view, edit, or delete your books, reviews, and profile inside the Service at any time.
• To delete your entire account and all associated data, email contact@concento.io and we will process the request within a reasonable time.

7. Children's privacy

The Service is not directed at children under 13. If we learn we have collected a child's data by mistake, we will delete it promptly.

8. Changes to this policy

If we make material changes, we will announce them on the site. Continued use of the Service constitutes acceptance of the updated policy.
