This policy is a draft and may be revised before the official release.

1. About this policy

This policy explains information handled through the Rakugaki Beast official website, browser demo, and contact form.

2. Browser-demo information

When you choose “Turn into a Beast with AI” in the browser demo, your drawing (PNG), chosen nickname, language setting, and Turnstile token are sent to our evaluation service on Cloudflare Workers. The image is sent to the Anthropic API for evaluation.

The evaluation service does not cache or persist the image itself. Its hash is used when forming the response. To limit use, the service keeps a counter based on a hash of your IP address for up to 48 hours.

3. Contact form

The contact form receives an optional name and email address, topic, message, referring page, and browser information. This information is stored in Cloudflare KV only to handle your inquiry and is deleted automatically after 180 days.

IP addresses are used only for a submission rate-limit counter and are not stored with the message. That counter expires within one hour.

4. Abuse prevention and analytics

The browser demo uses Cloudflare Turnstile to prevent abuse. The current official site does not use Cloudflare Web Analytics, other behavioural tracking, or advertising cookies.

5. Use and sharing of information

We use this information only to evaluate the demo, respond to inquiries, prevent abuse, and operate the service safely. Image evaluation uses the Anthropic API.
