Files are never uploaded — by design
FormatDrop performs all conversions entirely inside your browser using WebAssembly. Our server has no file upload endpoint — it physically cannot receive your files. Open DevTools → Network tab and convert anything. You will see zero upload requests. This is an architectural guarantee, not a policy claim.
What we collect
- Email address: Only if you purchase a Pro subscription via Stripe. Used solely to send your magic login link and manage your subscription.
- Anonymous page analytics: Privacy-preserving analytics (page views only — no tracking cookies, no fingerprinting, no personally identifiable data).
- Stripe payment data: Payment processing is handled entirely by Stripe. We never see or store your card details.
Cookies
If you purchase Pro, we set a single HttpOnly cookie (fd_token) containing a JWT that identifies you as a Pro user. This cookie expires in 30 days and is renewed automatically when you use your magic link.
We do not use tracking cookies, advertising cookies, or third-party analytics cookies.
Data retention
Pro subscription status is stored in Redis with a 400-day TTL. If you cancel, it is deleted. Email addresses associated with expired subscriptions are automatically purged.
