We measure which notes are read and which LINE links are clicked to improve the site. The site analytics database records the page path, event type and link placement, referring domain (or internal navigation), time, and a random ID for each event. It does not store names, emails, IP addresses, browser details, or URL query parameters. The ID is not a persistent visitor ID; this analytics feature does not use cookies or browser storage for ongoing visitor tracking. Do Not Track or Global Privacy Control stops collection.
Reading list and storage
Marked notes are stored in this browser only; they are not sent to our server or synced between devices. Untick them or clear site data to remove them. Analytics records are kept in a database available only to authenticated administration. There is currently no automatic fixed deletion period; records are reviewed and deleted when no longer needed. They are not sold.
External services
The delivery platform may process IP and connection details separately to serve and secure the site. YouTube's embedded player loads only when you click play. External images and visits to LINE, YouTube, X, note, and other services send connection details under those services’ own privacy policies. If you contact us on LINE, we use the details you send to respond and retain them as needed; we do not share personal information without consent except where required by law or service provision.
