Privacy policy

The tools calculate in your browser. This site does not include its own analytics, tracking pixels, external fonts or external application scripts. It does not ask for personal names, contact information or account numbers.

Browser storage

Worksheet entries and checklist progress are saved in localStorage on your device when your browser allows it. The same browser can restore those entries later. Use the clear entries button on the relevant tool to remove its saved worksheet. You can also remove site storage through your browser settings. Each tool has its own stored worksheet.

If storage is blocked or unavailable, calculations still work and the tool displays a message. Avoid entering sensitive information in row references or period labels. Generic references are enough to connect a downloaded schedule with records that you keep separately.

Exports and print views

CSV export creates a file locally and asks your browser to download it. Printing uses your browser's print dialog. Downloads and printed copies remain under your control, and this page cannot remove them when you clear entries. Clearing the tool removes its browser-saved state.

Hosting and official links

Hosting infrastructure may process ordinary technical requests needed to deliver the site. This static site does not include a tool that transmits worksheet entries. Clicking an official source link takes you to that source, which has its own privacy practices.

Third-party advertising

Empty ad containers reserve space on these pages. Third-party ads from Adsterra may be added later and may set cookies or use similar technologies. No advertising script is included in this staged version. Browser cookie controls can affect third-party storage if ads are introduced.
