What we collect

• Account: your email address and a scrambled (hashed) form of your password.
• Your worlds: the descriptions you write, the worlds built from them, and what each build cost.
• Players: character names, a hashed character password, and the character's progress in a world.
• Technical: a sign-in cookie, and server logs with IP addresses, kept briefly to keep the service running and stop abuse.

How it is used

To build and host your worlds, to sign you in, to keep within spending limits, and to prevent abuse. We do not sell personal information and we do not show ads.

Who else sees it

• Anthropic: the description you write is sent to Anthropic's Claude API to build the world. Do not put personal information in a description.
• DigitalOcean: hosts our servers.
• Google Fonts: serves the site's typefaces, which means your browser contacts Google when a page loads.

Cookies

One cookie keeps you signed in. There are no advertising or tracking cookies.

Keeping and deleting

Your account and worlds are kept until you delete them or ask us to. A deleted world is removed from play immediately and erased from our servers within 60 days. To delete your account or get a copy of your information, write to hello@instantmmo.com.

Children

InstantMMO is not for children under 13, and we do not knowingly collect their information.
