Privacy
What we collect, what we don't.
This site is built to collect as little information about you as possible. Nothing you type into the calculator ever leaves your browser.
The calculator
All calculation happens client-side. The numbers you slide or type into the spending categories are never transmitted to a server, never written to disk, and never associated with any identifier. Refreshing the page resets them.
Analytics
The site uses Google Analytics 4 to count visits in aggregate — page views, referrers, country, device type. IP addresses are anonymised by Google before storage. No personal identifier is sent. We do not use Google Analytics Signals or any cross-site advertising features.
Cookies
Google Analytics sets first-party cookies for visit counting (`_ga`, `_ga_*`). We set no other cookies. The calculator itself does not use cookies, localStorage, or any other client-side storage.
Third parties
The site loads three third-party resources:
- Google Fonts — Plus Jakarta Sans and DM Sans. May log IP addresses per Google's font-serving policy.
- Google Analytics — described above.
- Cloudflare — sits in front of our origin for HTTPS and caching. Cloudflare may log IP addresses for abuse prevention per its own policy.
We do not run advertising networks, retargeting pixels, or social tracking buttons.
What we never have
- Your name, email, address, phone, or any contact details.
- Your income, credit score, or financial accounts.
- Any record of which cards you looked at or which sliders you moved.
Children
This site is not directed to children under 13. We do not knowingly collect data from them.
Changes
If this policy changes substantively, the "Last updated" date at the top of this page will move and the change will be summarised here.
