Privacy Policy

Last updated: March 17, 2026

This Privacy Policy explains how GPTypo ("we," "us," or "our") collects, uses, and protects your information when you use gptypo.com (the "Service").

1. Text Submissions

When you paste text into GPTypo for scanning, your text is sent to our servers for analysis. For free-tier users, text is processed locally using our heuristic scoring engine. For Pro users, text is sent to our AI detection model hosted on Replicate for neural model verification.

We do not permanently store the content of your text submissions. Text is held in memory only for the duration of the scoring request and is discarded after the response is returned.

2. Rewrite Suggestions

When you request rewrite suggestions for flagged sentences, your sentence and surrounding context are sent to Anthropic's Claude API for processing. Anthropic's data retention and privacy policies apply to this processing. We do not store the suggestions after they are returned to you.

3. Account Information

If you create an account, we collect your name, email address, and profile image from your authentication provider (Google or email magic link). This information is stored in our database hosted on Supabase (Postgres) and is used to manage your account, subscription, and session.

We store the following account-related data: email, name, profile image URL, subscription tier, and Stripe customer and subscription IDs.

4. Billing

Payment processing is handled entirely by Stripe. We do not store your credit card number, expiration date, or CVC on our servers. We store only your Stripe customer ID and subscription status to manage your Pro tier access.

5. Cookies and Analytics

We use session cookies to maintain your authentication state. We use Vercel Analytics for anonymous, aggregated usage metrics. We do not use Google Analytics or any third-party advertising trackers.

6. Third-Party Services

We use the following third-party services to operate GPTypo:

  • Supabase — database hosting (account data)
  • Stripe — payment processing
  • Anthropic (Claude API) — rewrite suggestions
  • Replicate — AI detection model hosting
  • Vercel — application hosting and analytics
  • Google OAuth — authentication
  • Resend — magic link emails

7. Data Deletion

You can request deletion of your account and all associated data by emailing us. Upon deletion, we remove your account record from our database and cancel any active Stripe subscription.
