The short version
Voting doesn't require an account and isn't tied to your identity. Your ZIP code, if you enter one, never leaves your browser. Roll Call doesn't ask for your name, email, or any other personal information anywhere on the site.
Voting
Casting a vote doesn't require a name, email, or account. The first time you vote, your browser generates a random identifier and stores it on your own device (in "local storage") — this is what prevents the same browser from voting twice on the same bill. It isn't linked to your name or any other identifying information.
When a vote is recorded, the server also stores a one-way cryptographic hash of the IP address it came from, alongside the vote. This can't be reversed back into your actual IP address — it exists only so that, if the tally is ever obviously abused (the same handful of IPs voting hundreds of times, say), that pattern is visible after the fact. It isn't used to identify individual voters and isn't shown anywhere on the site.
Contact your Senators (ZIP code)
The ZIP code you enter to find your Senators is matched against a fixed, built-in table, entirely in your browser — it is never sent to this site's server or database in any form. It's saved in your browser's local storage purely so you're not asked again on your next visit, and you can clear it at any time with the "Change it" link in that panel. Clicking through to a Senator's official website takes you to a government site outside Roll Call's control, with its own separate privacy practices.

Who else touches this data
Running any website on the public internet involves a small number of infrastructure providers who handle data as part of making the site work — not for their own purposes. For Roll Call, that's:
- Cloudflare — hosts the site and handles standard web traffic (including the usual server-level access logs and security/DDoS protection every host keeps).
- Supabase — the database that stores bills and vote tallies.
- Congress.gov — the U.S. government's own API, queried by the site's backend to fetch bill data. No visitor data is ever sent to it.
- Google Fonts — this page's typefaces are loaded directly from Google's font servers, which means your browser makes a request to Google to fetch them, similar to loading an image from a website. Google can see that request came from your IP address, the same as any server you connect to. No Roll Call data is shared with Google beyond that.
Cookies and local storage
Roll Call doesn't set tracking cookies. It does use your browser's local storage — a per-site storage feature separate from cookies — to remember a few things on your own device: your anonymous voter identifier, which bills you've already voted on, and your ZIP code (if entered). None of this is readable by other websites, and clearing your browser's site data removes all of it.
