Privacy Policy

Last updated: 2026-07-20

Who we are

Vessel Maker is operated by Marco Siino (“we”, “us”). You can reach us at siino.marco@gmail.com for any privacy question or request.

You can use Vessel Maker without an account

The editor, 3D preview, and export of designs that use only free features all work without signing in and without any data leaving your browser. We only collect data once you choose to sign in to unlock a paid subscription or to use the admin dashboard.

What we store

  • Account data — when you sign in with Google, we store your email address, display name, and profile picture URL as provided by Google. We never see or store your Google password.
  • Entitlement records — your subscription tier (Pro/Commercial), how it was granted (a redeemed code or a manual grant), and its expiry date (or that it's a lifetime grant), so we know what your account is entitled to.
  • Redemption codes — if you redeem a code, we record which account redeemed it and when.
  • Session cookie — a strictly-necessary cookie that keeps you signed in. It is not used for tracking or advertising.

Your Gemini API key (used for AI rendering) is stored only in your browser's local storage and is never sent to or stored on our servers — requests are relayed through our server to Google's API without being logged or persisted.

Your vase project files are stored locally on your device as JSON files and are not uploaded to our servers by this feature.

Processors we use

  • Google — identity provider for sign-in (Google OAuth). See Google's Privacy Policy.
  • Our hosting and database providers — used to run the application and store the account/entitlement data described above.
  • If we add a payment provider in the future (for self-serve checkout), it will be a merchant of record responsible for handling payment details and applicable tax directly — we do not store card details ourselves.

Cookies

We only use a strictly-necessary session cookie to keep you signed in. We do not use analytics or marketing cookies, so no cookie-consent banner is shown.

Your rights

You can delete your account and all associated data (profile, entitlements, redeemed-code history) at any time from Settings. You can also contact us at the email above to request access to, correction of, or deletion of your data.

Changes to this policy

If this policy changes materially (for example, if we add a new processor such as a payment provider), we will update this page and the “Last updated” date above.
