This is a plain-language summary of what happens to your data when you use this site. The short version: the calculators' math runs entirely in your browser (we never see or store your salary, rent, or mortgage figures), we don't ask you to create an account, and we don't sell or share personal data with advertisers — but the site does use analytics and advertising tools that involve cookies, covered below.
The actual calculations (salary, rent, mortgage figures, and so on) happen entirely client-side, in your own browser — they are never transmitted to, or stored on, any server we operate, and refreshing or closing the page clears them completely. Separately, if you've consented to analytics cookies (see below), our session-recording tool may capture on-screen interactions with the page, including clicks, scrolling, and potentially the values typed into input fields. This is a different thing from "sending your numbers to our server" — it's a third-party analytics tool observing how the page is used, not our calculators sending data anywhere.
This site is hosted as a static site (e.g. via GitHub Pages). Our hosting provider may automatically log standard technical data for security and performance purposes — things like IP address, browser type, and page requested — under its own privacy practices. We do not have access to, and do not separately collect, this data ourselves.
If you email us or use a contact form, we'll have whatever you choose to include in that message (e.g. your email address and message content). We use this only to respond to you, and don't add it to a mailing list without your separate consent.
This site uses Google AdSense to display advertising, Google Analytics to understand how the site is used, and Microsoft Clarity for session recording and heatmaps (seeing, in aggregate, where people click and scroll). All three may set cookies. If you're in the UK, EEA, or Switzerland, you'll be shown a consent prompt before any of these cookies are set for advertising or analytics purposes — until you respond, both Google's and Microsoft's tools are configured to run in a denied/no-cookie state by default. You can change your choice at any time via the "Manage cookie choices" link in this site's footer.
Because Microsoft Clarity can record on-screen interactions, it's technically possible for a session recording to show what was typed into a calculator's number fields (salary, income, property price, etc.) if you've consented to analytics cookies. We haven't independently audited every masking setting on the Clarity side — if this matters to you, the safest approach is to decline analytics cookies via the consent prompt, or use "Manage cookie choices" to opt out at any time.
You can review and adjust ad personalisation at adssettings.google.com, read how Google uses data from sites that use its services at policies.google.com/technologies/partner-sites, and read Microsoft's Clarity-specific privacy notes at clarity.microsoft.com/legal/privacy-notice.
We don't sell, rent, or share your data with advertisers or data brokers ourselves. The third parties involved in running this site are:
Because we don't collect or store the numbers you enter into a calculator, there's generally nothing tied to you for us to provide, correct, or delete on that front. For anything you've sent us directly (e.g. a contact email), or any analytics data Google/Microsoft hold about your visits, you can ask us to help with a deletion or access request at any time — see the Contact page.

Not a substitute for legal advice. This policy is a general-purpose template intended for a small, static, informational site running third-party ads. It has not been reviewed by a lawyer. If this project grows — more data collection, EU-specific offerings, or larger scale — have it properly reviewed against the GDPR/UK GDPR, the Australian Privacy Act 1988, and any other applicable law before relying on it.
