Privacy

Your numbers stay yours.

Arthly is built to need as little of your data as possible.

Calculations run on your device

Every calculator runs entirely in your browser (web) or on your phone (app). The amounts you enter — salary, loan, investment — are not sent to or stored on our servers. No account or sign-up is required to use any calculator.

What we do collect

We use privacy-respecting, aggregate analytics to understand which calculators are popular and to fix problems. This does not include the specific figures you type. If you save plans in a future version, that feature and its data handling will be described here before it ships.

Partner links

When you tap a “Partner offer”, you leave Arthly for that partner’s site, which has its own privacy policy. We may receive a commission if you sign up — see how we make money.
