Double runs as a local demo in your browser. When you drop a file, we read it on your device and generate the doubled list right there — nothing is uploaded, stored, or sent to a server.

If you sign up, we collect your email address so we can send you one setup message. We don't sell it. We don't share it. We don't spam it.

If the real product launches with paid plans, billing will be handled by a standard payment provider (Stripe) and governed by that provider's policies. No card details touch our systems.
