Privacy Policy
Last updated: August 2026
What we collect
Only an email address, and only if you choose to give us one. There is no account, no login and no tracking of you as an individual. Calculator inputs are worked out entirely in your browser and are never sent to us or to anyone else. If you use Save scenario, those numbers stay in your browser's own storage on your device.
The email list
If you sign up for HYSA Rate and Fed Watch we store your email address so we can send you those updates, and nothing else. We do not ask for your name. We never attach your calculator figures to your address, because those figures never reach us in the first place. We do not sell, rent or share the list. You can unsubscribe at any time by replying to any email we send you, and we will remove you. Sending is handled by Resend, our email provider, who processes the address on our behalf.
Analytics
We use Google Analytics 4, loaded through Google Tag Manager, to count page views and sessions and to see which pages people find useful. We do not ask for your name, email, or any other detail that identifies you, and we do not upload your calculator inputs. Google receives your IP address and device information as part of providing the service.
Cookies
Google Analytics sets its own cookies in your browser to tell one visit from another. We do not set advertising cookies and we do not sell data to advertisers. You can block cookies in your browser settings, or install the Google Analytics opt-out add-on, and the calculators will still work normally.
Your calculator inputs
Everything you type into a calculator is worked out inside your browser and never reaches our servers. If you press Save scenario, those numbers are kept in your browser's own localStorage on your device. Clearing your browser data removes them.

Third-party links
This site links to external financial institutions. We are not responsible for the privacy practices of those sites.
