Privacy Policy

What we collect

When you sign in and take the 25/50 pledge, we collect:

• Account information — your name, email address, and profile photo from your sign-in provider (Google, GitHub, X, or Apple)
• Pledge details — the name, country, city, email, year of birth, and organization you provide on the pledge form
• Authentication data — a unique user ID and provider identifiers managed by Firebase Authentication

How we use it

• To create your account and issue your pledge badge
• To display your name and country on the public pledger list (if you take the pledge)
• To send you a sign-in link if you choose passwordless email authentication
• To prevent duplicate badge issuance across sign-in providers

What we don't do

• We don't sell or share your personal data with third parties
• We don't send marketing emails
• We don't use your data for advertising
• We don't track you across other websites

Where your data lives

Your data is stored in Google Cloud Firestore, managed through Firebase. Authentication is handled by Firebase Authentication. Both are governed by Google's privacy and security practices.

Your rights

You can request deletion of your account and all associated data by contacting us at privacy@2550.org. We will process deletion requests within 30 days.

Cookies and analytics

Changes to this policy

We may update this policy from time to time. Changes will be posted on this page with an updated date. Continued use of the site after changes constitutes acceptance.
