Privacy & cookies
Updated 4 November 2026 · Educational content
Last updated: 4 November 2026. This page describes the website code supplied with this version of Coffee or Stocks.
Calculator inputs
Calculations run in your browser. The calculator code does not send the purchase name, amount, frequency, years or return assumption to a server. It does not create an account or save these inputs in cookies or local storage. Reloading the page resets the form to its defaults.
Hosting and ordinary requests
When you visit a website, its hosting provider receives technical request information such as your IP address and browser details to deliver the pages. Hosting log retention and processing depend on the provider operating the live site.
Google advertising
This version includes Google AdSense code. If advertising services operate on the live website, Google and its partners may use cookies or similar technologies and process information for ad delivery, measurement and, where permitted, personalisation. Learn how Google uses information from sites that use its services and read Google's privacy policy.
Where an advertising consent message is displayed, use its controls to make or change your choices. You can also review Google's My Ad Center. Browser settings allow you to delete or block cookies; this may affect third-party features. This page itself does not provide a consent-management system.
Fonts and external links
The site loads fonts from Google Fonts, creating requests to Google's font services. External resource links take you to websites with their own privacy practices. The calculator does not need you to open these links to work.
Scope of this notice
This version adds no analytics, newsletter signup, payment form or contact form. If the live operator adds services or changes the hosting or advertising configuration, this notice must be updated to describe those changes accurately.
