Privacy Policy for chiristo.dev
Effective Date: June 27, 2026
At chiristo.dev, your privacy is important to us. This policy explains how we collect, use, and protect your information.
1. Information We Collect
- Name
- Profile picture
- Email address (for signup and newsletter subscription)
- Anonymous session identifiers (Firebase anonymous UID) for users who comment as a guest without signing in
- Comment content — the text of comments and replies you post on blog posts
- Comment interactions — likes you place on comments, associated with your user identifier to prevent duplicate interactions
2. How We Use Your Information
- To send you blog updates, newsletters, or other site-related emails
- To improve our content and user experience
- To display your comments and replies on blog posts
- To track comment likes and prevent duplicate likes per user or guest session
- To associate guest sessions with comment activity during your visit
3. Data Storage and Security
- Authenticated users (Google or GitHub sign-in): your name, profile picture, email address, and comment history are stored in Firestore.
- Guest users: an anonymous session identifier and any comments or replies you post are stored in Firestore. No name, email address, or profile image is collected for guest users.
- Comment likes are stored against your user identifier (authenticated or anonymous) to prevent duplicate interactions.
- We do not sell or share your personal information with third parties.
4. Guest Users and Anonymous Comments
- Users who choose to comment without signing in are assigned a temporary anonymous identifier by Firebase Authentication. No personal information is required or collected.
- This identifier is used only to associate comments and likes with your session.
- Anonymous sessions may persist across page refreshes within the same browser but are not linked to any personal identity.
- If you later sign in with Google or GitHub, your anonymous session may be linked to your account so your existing comments are preserved.
- You can request deletion of guest-session data by contacting us at chris@chiristo.dev.
5. Newsletter and Unsubscribe
- You may unsubscribe from our newsletter at any time using the link in each email or by contacting us directly.
6. Your Rights
- Authenticated users can request deletion of their account and all associated comments by contacting us at chris@chiristo.dev.
- Guest users can request deletion of comments made during an anonymous session by contacting us with the approximate date and content of the comments.
- You may also request access to or correction of any data we hold about you.
7. Contact
