Your plan stays in the page.
Reading Days Planner performs its calculations in your current browser page. It does not send your dates or page counts to a calculation service.
What happens to your inputs?
Inputs remain in current page memory only. Refreshing or closing the page loses them. We do not use accounts, cookies, analytics, advertising, localStorage, session storage, uploads, or third-party scripts.
CSV downloads are created locally by your browser. Printing uses your browser’s print dialog. The host may process ordinary HTTP access data needed to serve a static website, such as an IP address, request time, and user agent, according to its infrastructure provider’s practices.
What this tool does not do
It does not read book content, infer reading ability, promise learning outcomes, or automatically add US holidays. It is a math-only one-book planning aid.
