Privacy Policy — ThePrisonList Chrome Extension
Last updated: June 17, 2026
Overview
The ThePrisonList Chrome Extension ("the Extension") is a leaderboard viewer for ThePrisonList.com. This policy explains what data the Extension accesses, how it is used, and what is never collected.
Data We Do Not Collect
The Extension does not collect, store, transmit, or share any personal information. Specifically:
We do not collect your name, email address, or any account information
We do not track your browsing history or activity on other websites
We do not use cookies
We do not run analytics or advertising scripts
We do not sell or share any data with third parties
Data Fetched From ThePrisonList.com
The Extension connects to the ThePrisonList.com database to retrieve the public leaderboard. This includes:
Entry names and descriptions submitted by the community
Vote counts for each entry
Usernames of people who submitted entries
This is the same public information visible to anyone who visits ThePrisonList.com without an account. The Extension only reads this data — it does not write, modify, or delete anything.
Local Cache
To reduce server load and improve performance, the Extension temporarily stores leaderboard data in your browser's local storage (chrome.storage.local). This cache:
Contains only the public leaderboard data described above
Expires automatically after 5 minutes
Never leaves your device
Can be cleared at any time by removing the Extension
External Service
The Extension communicates with Supabase (supabase.com), the database service used by ThePrisonList.com, solely to fetch public leaderboard content. No personal data is sent to Supabase through the Extension. Supabase's own privacy policy is available at supabase.com/privacy.
Links to ThePrisonList.com
Clicking vote buttons, the "Sign up & vote" button, or the "Submit a name" button opens ThePrisonList.com in your browser. Once on the website, ThePrisonList.com's own privacy policy applies.
Changes to This Policy
If this policy changes, the updated version will be posted at theprisonlist.com/privacy with a new effective date.
