This page explains how "Katana — Japan Stock Screener" (the "Service") handles user information.
The Service is fully usable without creating an account. We do not ask for personal information such as your name or email address. (If a future feature requires registering an email address, this will be disclosed explicitly on that feature's page.)
Filter settings, favorites, and language/theme preferences are stored only in your browser's localStorage. This information is never sent to or stored on the operator's servers. Clearing your browser data will erase these settings.
The Service uses the following analytics services to understand usage. Both are cookie-free or do not identify individual visitors.
The Service does not sell or provide users' personal information to third parties. Aside from the analytics services above, there is currently no mechanism that sends user data to external services.
This Policy may be revised as new features are added to the Service (e.g., email registration for a notification feature). Revised content takes effect from the time it is posted on this page.
For inquiries regarding this Policy, please contact us via the address listed on the About / Operator page.
