Privacy Policy

Last updated: September 2026.

What we collect

RoofCalcWorks calculators run entirely in your browser. The values you enter are not stored on our servers. We collect anonymous, aggregated usage analytics (which calculators are used and whether calculations are completed) to improve the product. We do not collect personal information through the calculators.

Saved projects (local storage)

If you use the Save Project feature, your saved calculations are stored in your own browser's local storage on this device. They are never uploaded to our servers. Clearing your browser data removes them. Up to 20 projects are kept at a time.

Analytics

We use privacy-respecting, aggregate analytics. Event data never includes your inputs, only that a calculation occurred and coarse usage patterns.

Contact form

If you contact us, we use your email address only to respond to your message.

Changes

We will update this policy as the product evolves and note the date of any change above.
