Your financial data never leaves your device
We know you are entering sensitive information. Here is exactly how we protect it — and why you can verify it yourself.
Calculated in your browser
Every calculation runs in JavaScript on your own device. Your salary, pension contributions, and family details are processed locally — not transmitted anywhere.
No server receives your data
There is no API endpoint that receives your financial inputs. When you type a number, it goes straight to the calculation engine inside your browser tab.
No database, no storage
We do not store anything you enter in any database. Your scenario data exists only in your browser's memory and disappears when you close the tab.
What we do collect
If you subscribe to our mailing list, we store your email address. We also receive anonymous Vercel page statistics such as view count. No financial data is ever collected.
