What we collect

RoomieMath is designed to work without an account. The calculator runs in your browser. We do not ask for your name, address, or payment details.

If you use “Copy link to share”, your inputs are encoded in the URL so someone else can open the same scenario. That means whoever you send the link to can see those values. Do not put sensitive information in room labels if you are uncomfortable with that.

Local storage

We may store a small flag in your browser (for example to remember that you dismissed a tip). You can clear site data in your browser settings at any time.
