1. What we collect

When you sign in with Google, we store your email address and a unique user ID in our database (Supabase). We do not store passwords. URLs you submit for meta tag generation are sent to Anthropic's API for processing and are not stored permanently.

2. How we use your data

Your email is used to identify your account, manage your subscription, and send transactional emails related to billing. We do not send marketing emails. Your subscription status is stored to determine whether you have access to Pro features.

3. Third-party services

We use the following third-party services: Supabase (database and authentication), Anthropic (AI processing), Lemon Squeezy (payments), and Vercel (hosting). Each has their own privacy policy governing how they handle data.

4. Rate limiting

For free-tier users, we store your IP address in Redis (Upstash) with a daily counter to enforce usage limits. This data expires automatically at midnight UTC each day.
