FAQ
HELP
Do I need an account? tap

No. You can use calculators anonymously. Sign-in is only needed for saving history and team workflows.

What does “3 included seats” mean? tap

The Team plan is designed to include 3 active members by default. Seat enforcement should be server-side when Team features ship.

Are results saved or shared automatically? tap

Not automatically. The pages provide a “Copy summary” feature so you can paste into job notes without storing customer PII. Saved history is planned for signed-in users.

Are subscriptions live right now? tap

They may not be enabled yet in the current build. This page documents the intended tier model and what will be available as rollout progresses.
