Arroyo

Privacy

Last updated: 2026-09-11

This page describes, in plain language, everything Arroyo collects about people who visit it — and everything it deliberately does not.

What Arroyo never collects

• No accounts, no sign-in, no user profiles.
• No precise location. The site never requests device GPS/location permission.
• No names, email addresses, or other personal identifiers, ever.
• No photos, reports, or messages — the site has no submission mechanism at all.

Analytics: what's actually running

Arroyo uses Google Analytics 4 (GA4) to understand, in aggregate, how many people use the tool and which parts of it get used — nothing more. This is used to improve the tool and to report usage to the people and organizations who support it.

What GA4 measures on this site:

• Page views and session counts.
• Approximate country/region and device type, derived by Google from IP address — Arroyo does not receive or store your IP address or exact location.
• Which language you use the site in, which basin you view, and which links you click (for example, an official-source link to Alert LA County or the National Weather Service).

What it does not do:

• Google Signals and ad personalization are switched off — this data is never used for advertising, on this site or anywhere else.
• No cross-site or cross-device tracking.
• Analytics data is not sold or shared, beyond Google's role as the processor running the analytics service itself.

Cookies

GA4 sets a small number of first-party cookies (typically named _ga and _ga_<container-id>) to distinguish one visit from another. Arroyo does not set any other cookies, and does not use cookies for advertising or cross-site tracking.

Data retention

Analytics event data is retained for 2 months, the shortest option GA4 offers — chosen deliberately, because this is a community safety-information project, not a project that needs a long behavioral history of its visitors.

Your choices

The site is fully usable with analytics blocked. Browser tracking-protection features, ad blockers, or Google's own Analytics opt-out browser add-on will all prevent analytics from running without breaking anything else on the page.

What Google does with this data

Google processes this analytics data under its own privacy policy. Arroyo's role is limited to configuring GA4 as described above — it does not build its own separate database of visitor behavior outside of Google's platform.

Contact

Arroyo does not currently publish a dedicated contact channel. This section will be updated once one exists.
