Privacy Policy
Last updated: 9 June 2026
The short version
This is a free, static calculator. Everything you type stays in your browser. We have no accounts, no login, and no server that receives your figures. We do not sell or share personal data because we do not collect any.
What we do not collect
- We do not collect your name, email, bond numbers, or holdings.
- The amount you enter is used only by JavaScript on your device to show results. It is never sent to us.
Analytics & cookies
The current version sets no tracking cookies. We may use privacy-friendly, aggregate analytics from Umami and Cloudflare Web Analytics to understand page views, referrers, device/browser types, approximate geography, and basic page performance. These analytics must not receive the bond amount or any other calculator values you type.
Third-party links
We link to official sources such as NS&I for reference. Those sites have their own privacy policies, which we do not control.
