Short version: the calculators run entirely in your browser. The numbers you type are never transmitted to us and never stored on a server.
What we do not collect
Your income, balances, debts, ages, and every other figure you enter into a tool stay on your device. There is no request that carries them anywhere.
What we do collect
When a calculation runs, we record an anonymized summary of its shape — for example that someone ran the runway tool, landed in the one-to-three-month band, and has variable income. These records contain bucketed ranges, never your actual figures, and never any label you typed. They tell us which questions people are asking so we can write about them.
If you give us an email address, we use it to send what you asked for and to tell you when something relevant changes. You can leave at any time from any email. We do not sell your address.
Affiliate relationships
Some links to financial products pay us a commission if you open an account. Those links are ordinary web links; following one tells the destination that you arrived from this site. It never changes the output of a calculator.
