knowground extension — Privacy Policy

Last updated: July 15, 2026

This policy covers the knowground browser extension — a toolbar popup that looks up FEMA flood, USGS elevation, and FCC broadband figures for a US ZIP code, city, or county. It requests no browser permissions, so its install screen shows no "read/change your data" warnings; it can do only two things — search when you type, and show the figures for a place you pick.

What the extension does NOT do

• It does not read the pages you visit — no access to your tabs, browsing history, or any website's content, and it never reads, stores, or transmits the URL of a page you are viewing.
• It sets no cookies and keeps no account — no sign-in, nothing saved on your device between uses.
• It contains no advertising, analytics, or tracking. Data it handles is never used or transferred for advertising or to build an advertising profile.

What it sends, and to whom — the extension contacts one service, knowground's own public API at www.knowground.com, and only when you act:

• The place you type (a ZIP code, city, or county name) is sent to the API to return matching places. It identifies a geographic area, not a person or account.
• The place you pick is sent so the API can return that place's published civic figures.
• Standard request data: like any web request, these reach the server with your IP address, recorded in ordinary server logs (request, timestamp, IP) used only to operate and secure the service and kept for a limited period. No cookies are sent; it is not used to profile you.

That is the extension's entire data footprint. Nothing else leaves your device.

Your choices & contact — there is no account and no stored profile to delete; removing the extension from your browser's add-ons page ends all activity immediately. Questions or a data request: privacy@knowground.com.
