Privacy Policy
Last updated: 5 September 2026
The short version
Your calculations never leave your browser. All calculator maths runs client-side on your device — we never see your investment amounts, loan details, or projections. We collect only what you explicitly give us (a newsletter email or contact message) plus standard, anonymised usage analytics.
What we collect
- Newsletter subscriptions: your email address, used only to send the newsletter you asked for.
- Contact form messages: name, email and message, used only to respond to you.
- Analytics: anonymised page views and calculator-usage events (no input values) via Google Analytics 4 and Microsoft Clarity, to improve the product.
- Advertising cookies: Google AdSense may set cookies to serve and measure ads. See our Cookie Policy for details and controls.
What we never do
- We never sell, rent or share your personal data with third parties for their marketing.
- We never store your calculator inputs or results on our servers.
- We never require an account to use any tool.
Your rights
You may request access to, correction of, or deletion of any personal data we hold (typically just an email address) by writing to us via the contact page. Newsletter emails include a one-click unsubscribe. Analytics and ads cookies can be blocked via your browser settings without affecting any calculator.
Data security & retention
Form submissions are stored in an access-controlled database over HTTPS. Newsletter emails are retained until you unsubscribe; contact messages are deleted within 12 months of resolution. We apply rate limiting and input sanitisation on all form endpoints.
