Your numbers stay yours.

This initial version of Numbers First does not require an account and does not store the calculator inputs you enter. Your inputs are used in your browser to show your result.

When you copy a scenario link, its inputs are included in the URL so the recipient can recreate that scenario. Avoid sharing a link containing sensitive personal or financial information.

We may add privacy-respecting aggregate analytics to understand calculator usage. This policy will be updated before any material change to data handling.
