<div>AntiFreeze is a free mobile app that lets communities report and receive real-time alerts about ICE activity nearby, anonymously and without collecting the personal data that puts vulnerable families at risk.

</div>

<div><br />

</div>

<div>Since launching in March 2026, AntiFreeze has grown to over 4,200 users. Version 2.0 just shipped with self-hosted push notifications (no reliance on third-party services like OneSignal that can be subpoenaed or sold), GPS opt-out for people who don't want location tracked at all, and automatic 48-hour visibility limits on sighting reports. After 48 hours, reports disappear from the public feed so the data can't be used to build a live picture of anyone's movements. Historical reports remain accessible to admins and vetted watchdog partners for pattern verification and accountability, but they're never public-facing after that window.

</div>

<div><br />

</div>

<div><br />

</div>

<div>AntiFreeze also runs a Trusted Watchdog Panel so vetted community organizations; like IceWatchSoCal  can verify and coordinate reports in their area, adding a layer of accountability without compromising anonymity.

</div>

<div><br />

</div>

<div>The project is protected under Cloudflare's Project Galileo (free protection for at-risk civil society groups), has been reviewed by the EFF, and is backed by Vanderbilt Law School's First Amendment Clinic for legal support.

</div>

<div><br />

</div>

<div><strong>Why I need help:</strong>

</div>

<div>I'm a solo developer building and maintaining this in my off-hours. As usage grows, so do my real costs:

</div>

<div><br />

</div>

<div><strong>Server infrastructure</strong> — scaling database, push notification, and API capacity to handle thousands of concurrent users during raid events (when traffic spikes hardest)

</div>

<div><br />

</div>

<div><strong>SMS/push notification costs</strong> — reaching users who need alerts fastest

</div>

<div>Legal and compliance support — working with Vanderbilt's clinic to make sure the app stays on solid First Amendment ground as it grows

</div>

<div><br />

</div>

<div><strong>Legal defense reserve</strong> — the Trump administration has publicly threatened apps that track ICE activity. If AntiFreeze faces a legal challenge, a subpoena, or targeted action, I need to be able to hire outside counsel on short notice. This isn't hypothetical, it's a real risk of running this project

</div>

<div><br />

</div>

<div><strong>Security audits</strong> — this app protects vulnerable people; it needs to be bulletproof against both bugs and bad actors

</div>

<div><br />

</div>

<div><strong>Continued development</strong> — new features like SEO/discoverability so people in danger can actually find the app when they need it

</div>

<div><br />

</div>

<div><strong>Where the money goes:</strong>

</div>

<div><br />

</div>

<div>I'm not a nonprofit — this is an independent civic tech project. Every dollar goes directly to hosting, infrastructure, and the tools needed to keep AntiFreeze free, ad-free, and privacy-first for the people who depend on it.

</div>

<div><br />

</div>

<div>If you can't donate, sharing this with someone who needs it or with a local immigrant rights organization — helps just as much.
