Highlights (informational summary, not a substitute)

We collect uploaded files and conversion results, usage logs, and — for the paid plan — your email address and subscription status. Credit card numbers are handled by Stripe and never touch our servers.
Your drawings are never sold or provided to third parties.
Processing is delegated to Cloudflare (hosting/storage), Google Cloud (conversion, Tokyo region), Neon (database), Stripe (payments), and Resend (login emails).
No external analytics tools or advertising cookies are in use. We measure usage in-house without cookies (pages viewed, action types, and referring site domain, tied to an anonymous session ID that disappears when you close your browser — nothing personally identifiable). Login sessions use browser local storage.
