We operate the InboxCheck Chrome extension and the inboxcheck.io website. This privacy policy explains how we collect, use, and protect your data.

Data We Collect

Email Addresses Submitted for Verification

When you verify an email address, we hash it using SHA-256 before storing it in our database. We do NOT store raw email addresses. The email is processed by our proprietary verification engine to check deliverability.

Account Information

When you create an account, we store your email address and encrypted password (or OAuth identity). Authentication is managed by Supabase Auth.

Usage Data

We track the number of verifications you perform, timestamps, and verification results (Safe/Risky/Unsafe) for rate limiting and analytics.

Browser Extension Data

The extension stores your preferences (e.g., disabled sites, inline detection settings) in your browser's local storage. This data is never sent to our servers.
