Privacy (beta)

Last updated: 2026-10-02. This is a translation of the Japanese policy; if they differ, the Japanese version prevails.

Where your submission goes

To score it, the work you send (images, PDF, text) is sent to the API of the AI (Claude) provided by Anthropic, PBC. It is sent only when you press the score button after ticking the consent boxes.

What we do not store

The Service does not store the work you send or the text of the result on its servers. They are discarded once scoring is finished.

What a share link contains

If you share a result, the link URL contains only the kind of work, the heat level, the total score, the title, the one-liner and the language. It never contains the work itself, the per-criterion feedback or the rewrite examples.

Abuse prevention

To prevent abuse, we count requests per IP address over short periods (Vercel’s firewall and an in-memory counter on the server). These records expire after a short time.

Analytics

To improve the Service we use Google Analytics (Google LLC), which uses cookies to measure pages viewed, features used (kind, heat level, score, use of share buttons, etc.), approximate region and device type. The content of your work and the feedback are never sent. See Google’s policy; you can opt out with your browser settings or the opt-out add-on.

We also use Microsoft Clarity (Microsoft Corporation), which uses cookies to record interactions on the page (clicks, scroll position). All text on the screen is masked in the recording, and the work and feedback you see are never sent. Clarity is not loaded on share pages (pages starting with /s/). See the Microsoft Privacy Statement.
