DisposableGuard

Privacy — DisposableGuard

Plain English. No tracking pixels. We don't store full email addresses.

What we collect

When you call the API:

  • Domain only (e.g. mailinator.com). We extract the domain from the email you send and drop the local part. The full email never hits disk.
  • • The verdict (is_disposable true/false).
  • • Your API key ID, so we can attribute usage for billing.
  • • IP address, for rate-limiting and country-level analytics (no precise geolocation).
  • • User-Agent and Referer (when present), for traffic analytics.

When you sign up:

  • • Email address, name, password (hashed via NextAuth).
  • • Stripe customer ID (for paid plans).

What we do NOT collect

  • • The full email addresses you check via the API.
  • • The content of any messages.
  • • Any per-user behavioral telemetry beyond the above.
  • • Third-party trackers or pixels (no Google Analytics, no Hotjar, no Facebook Pixel).

Where the data lives

  • • Application: self-contained Next.js deployment on Vercel.
  • • Database: Upstash Redis for rate limiting and API key storage.
  • • Payment processing: Stripe.
