Know what is saved, and where.

What stays in this browser

My bookshelf

Stores only identifiers of the articles you save. Japanese and English pages on the same site share the shelf. It is not synchronized to other devices.yorimichi:favorites:v1

First-arrival presentation

Remembers whether you have visited so the arrival presentation need not repeat. It does not record dates, visit counts or browsing history.yorimichi:arrival:v1

Home motion

Remembers whether you pause or resume motion. It does not store the room you choose or a browsing history. Your device’s reduced-motion preference takes priority.yorimichi:worlds-motion:v1

Article return paths

Stores up to 12 recent article return paths in this tab. A path from search includes its query and category. Records older than 30 minutes are ignored and removed when the feature next runs. Restoring a tab may restore its stored context.yorimichi:return-context:v1

These storage features do not transmit their saved records externally. If browser storage is unavailable, some settings may be lost when you leave a page.

Clearing saved data

Remove saved books with the clear-all control in My bookshelf. Deleting this site’s stored data in your browser also clears arrival and motion preferences. The button below clears only this tab’s article return paths.

Search URLs and external destinations

The search page URL contains the search term. Reloading, opening or sharing it may leave that term in browser history or hosting access logs. Do not include confidential information or personal contact details in a search. Search terms and identifying tokens are not added to article URLs.

Article sharing passes only the title and public URL to the destination you choose. The LINE button opens an external site when selected. Search terms and browsing history are not added to the shared text. Copying a link writes it to this device’s clipboard.

Following a source link takes you to another site with its own policies. Pages are delivered through Cloudflare, so browsing requires communication with that hosting service. Avoiding browser storage does not mean that no network communication occurs.

In this public edition, navigation within the site retains the previous page URL as the referrer. Requests to other sites are configured to omit the HTTP Referer header. Referrer information sent by analytics is separate from that header.

Information in contact messages

Contact us by email at [email protected]. When you send an email, your sender address, message and any information you attach pass through your email service and Cloudflare Email Routing to the operator’s receiving mailbox. They are used to review the message, handle it and reply where appropriate, and are not posted as public comments.

The link opens your email application. A form for entering and submitting messages on this site is not active. Email drafts and retention depend on the email services and the receiving mailbox’s handling practices. The site does not read the contents or drafts in your email application.

Do not include card details, passwords or identity documents in a message. For a correction, the article URL, the passage in question and any useful reference are enough.

About analytics

The public site uses Cloudflare Web Analytics to aggregate page views, referrers, device types and loading performance on reading pages, including the home page, articles, rooms, features and categories. Analytics is not used on search, My bookshelf, contact or this information page.

This analytics service does not use cookies or browser storage to identify visitors. Our integration does not read saved-book records or contact message contents for analytics. Page and performance information, including the measured page URL and the previous page URL, may be sent to Cloudflare. Search terms appear in the search page URL and can therefore occur in a previous page URL.

Visits are not a count of individual readers. These aggregates cannot identify a person’s return rate, reading completion or willingness to subscribe. Browser settings and network conditions can also leave some views unmeasured.
