Privacy
Privacy policy
Short version: the calculator runs entirely in your browser and we don't need your data to give you a number.
Calculations
Every measurement you type into the stair runner calculator is processed locally in your browser. Nothing is sent to a server and nothing is stored unless you choose to save a project to an account.
Accounts
When Pro accounts launch, we will store only what is needed to run them: your email address, your business details, and the projects and client notes you create. You can delete your account and its data at any time.
Analytics and cookies
We use privacy-respecting aggregate analytics to understand which pages are useful. We do not sell data or run advertising trackers.
