Privacy

No advertising. Matomo measures site visits and link use; notes and personal schedules are never included. Optional first-party page and PDF counts require your permission.

Your data stays with you

Notes, exceptions and calculations are processed in your browser. Nothing is sent to a PDF generation service. “Remember on this device” uses local storage; switch it off to remove the saved copy. Exported files remain under your control.

Optional usage counts

Usage counts are available but remain off until you opt in using the checkbox below a calendar or PDF page. Permission applies to this tab and can be withdrawn using the same checkbox.

After permission: page type, language, region, year, month, output format and a broad referrer category. The usage log contains no visitor identifiers, IP addresses, user agents, full URLs or private text. The permission choice and referrer category use this tab’s session storage. PDF requests and errors do not prove printing or unique visitors.

Hosting and logs

The server receives the network requests needed to serve the site. The Docker configuration disables application access logs; your operator’s reverse proxy or network provider may retain connection metadata.

There are no accounts or shared storage. Closing a tab clears unsaved notes.
