Who we are

Closed Roles is a free Chrome extension made by MapleGate Systems, a sole proprietorship in Calgary, Alberta, Canada. Questions or deletion requests: support@mafiavoice.com

What the extension does

On YouTube watch pages of supported league videos, Closed Roles covers role cards and night actions so you can guess every seat yourself, then shows your score. It runs only on youtube.com.

What stays in your browser

Your marks (your guesses) for each game.
Your progress per video: the game you are on, the games you finished and their scores.
Cached marker data for videos you opened.
The list of supported videos, and whether sending feedback is allowed for this install.
The videos you asked us to analyse, with the time of each request.
A random install id, made once in your browser. It is not linked to your name, email or Google account.

This stays on your device (Chrome extension storage) until you remove the extension.

What is sent, and when

Markers download. When you open a supported video, the extension asks our Cloudflare-hosted server for that video's markers. This is a plain GET request that contains the video id. The extension also refreshes a public list of supported videos in the background. Nothing else is attached.
Feedback, only when you press Send. The text you typed, the video id, the second in the video, the game number, the extension version, the interface language and the random install id. The server adds the time it received the message. The developer reads new messages in a daily email sent only to the developer.
Request page, only when you submit it. The video id you entered, and our server keeps a request count and the first and last time that id was requested. Cloudflare Turnstile checks that you are not a bot (Cloudflare Turnstile privacy).

Nothing is sent automatically about what you watch. Marks, guesses and scores are never sent.

What we never collect

Your name, email address or Google account.
Your browsing or watch history.
Analytics, cookies or advertising identifiers.
Your IP address: we do not store it and we keep no server logs. Like any website, our host Cloudflare sees your IP address to deliver content and to run the bot check.

We do not sell or share your data, and we do not use it for advertising or credit decisions.

Retention

Feedback messages are kept until the owner has reviewed them and chooses to delete them. There is no automatic deletion. Request counts are kept in the same way. To have your feedback deleted, write to the contact above and include your install id if you can; the extension does not show it, so we may not be able to find your messages without it. Removing the extension deletes everything stored in your browser.

Limits

To stop spam, each install can send 3 feedback messages per day and 10 in 30 days. The install id exists for these limits and to block an install that sends spam.

Children

Closed Roles is not directed at children under 13 and we do not knowingly collect data from them.

Changes

If this policy changes, we will update this page and its date.
