TREMR

Tremr is a free, real-time earthquake monitoring tool. We take privacy seriously and keep things simple — we don't sell your data, we don't track you, and we store as little as possible.

Information We Collect

Tremr itself does not collect or store any personal data. The app runs entirely in your browser. The only information we may collect is:

• Email address — if you voluntarily join the Tremr Alerts waitlist. This is stored securely and used only to notify you when Tremr Alerts launches.

Third-Party Services

Tremr uses the following third-party services, each with their own privacy policies:

• USGS Earthquake Hazards Program — provides all earthquake data. No personal data is sent to USGS.
• Google Fonts — loads fonts from Google's CDN. Google may log font requests.
• Google Analytics (GA4) — measures site traffic and usage. Collects anonymised data such as pages visited, session duration, and approximate location. See Google's privacy policy.
• Leaflet.js / OpenStreetMap / ESRI — powers the interactive map. Map tile requests are made to ESRI's servers.
• Google AdSense — displays advertisements. See the advertising section below for full details.

Advertising

Tremr uses Google AdSense to display advertisements. Google AdSense is operated by Google LLC. As a third-party vendor, Google uses cookies — including the DoubleClick cookie — to serve ads based on your prior visits to this site and other sites on the internet.

Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to Tremr and/or other sites on the internet. You may opt out of personalised advertising at any time by visiting adssettings.google.com.

Cookies

Tremr itself stores one value in your browser's localStorage: your theme preference (light or dark mode). We do not set tracking cookies. Google Analytics (GA4) uses cookies to measure site traffic and user behaviour — this data is anonymised and used solely to understand how Tremr is used. Google AdSense may set its own cookies — including the DoubleClick cookie — for ad personalisation and frequency capping. You can manage or block these cookies through your browser settings or the opt-out links listed in the Advertising section above.

Location Data

If you use the "Near Me" feature, your browser will ask for permission to access your location. This is processed entirely on your device and is never sent to our servers.

Children's Privacy

Tremr is not directed at children under 13. We do not knowingly collect personal information from children.

Changes to This Policy

We may update this policy from time to time. The date at the top of this page reflects the most recent revision.
