Privacy Policy
The short version: the dates you enter stay in your browser.
Last updated: 2026-11-08
Data you enter into the tools
The calculators run in your web browser. The dates and numbers you enter are processed on your device by JavaScript on the page. The tool code does not send them to us or to a third party, and we do not log them. They are not saved in your browser and disappear when you close or reload the page.
Hosting and server logs
The site is delivered as static files by a hosting provider and content delivery network (Cloudflare). Like any web server, they may keep standard technical logs, such as IP address, requested page, browser type and time, to deliver the site and keep it secure. These logs do not contain the dates you enter in the tools.
Advertising
At the moment the site shows no advertisements and sets no advertising cookies. If we enable Google AdSense in future, Google and its partners may use cookies to serve and measure ads. We would update this page first, show a consent choice before loading any ad script, and ask visitors in the European Economic Area, the United Kingdom and Switzerland for consent through a certified consent management platform. You can manage personalised advertising at Google Ads Settings.
Analytics
We do not currently run analytics. If we add aggregate page-view statistics we will update this page first.
Children
The site is a general-audience utility and is not directed at children under 13, and we do not knowingly collect their personal information.
Your rights
Because we do not collect personal data through the tools, there is generally nothing to access, correct or delete. If you emailed us and want that message deleted, contact us and we will respond in line with applicable law.
Changes
If this policy changes, the new version will be published here with an updated date.
