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.
Riser accounts
If you create a Riser account we store only what is needed to run it: your email address, your business details, and the customers, projects, quotes and invoices you create. Account owners can download everything as a single file, set how long activity history is kept, and erase a customer's personal details on request. See security & data practices for the detail.
Analytics and cookies
We use privacy-respecting aggregate analytics to understand which pages are useful. We do not sell data or run advertising trackers.
