Privacy Policy — Skirmish

Last updated: August 12, 2026

Skirmish ("the Extension", "we", "us") is a Chrome extension that provides a local client for a 2D multiplayer shooter game. This policy explains what data the Extension and its associated game server collect, why, and how it is used.

1. Summary

We collect only what is needed to run your account and multiplayer matches: a username, email address, a hashed password, and gameplay statistics. We do not sell your data, do not use it for advertising, and do not include any analytics or third-party trackers in the Extension.

2. Data we collect

Data	Purpose	Stored where
Username & email address	Create and identify your account, sign-in	Game server database
Password	Sign-in authentication	Game server database, stored only as a salted hash — the plain password is never saved
Gameplay statistics (rating, wins, losses, kills, deaths)	Leaderboard, matchmaking	Game server database
Live match data (position, actions, chat/invites during a match)	Real-time multiplayer gameplay, sent over a WebSocket (wss://) connection	Processed in memory on the game server while a match is in progress; not permanently stored beyond the match summary
Game server address, selected language, sound/"do not disturb" preferences	Remember your settings between sessions	`chrome.storage.local` — stays on your device, never transmitted anywhere except to apply your chosen server address
IP address	Standard connection handling (WebSocket/TCP requires it); basic abuse prevention	Transient server connection logs

We do not collect your browsing history, the contents of other tabs, or any data from websites you visit. The Extension only activates its own local page (game.html) when you click its toolbar icon.

3. How data is used

To create and authenticate your account.
To run multiplayer matches (matchmaking, real-time gameplay, invites).
To maintain the leaderboard and your personal statistics.
To remember your local preferences (language, sound, server address).

We do not use your data for advertising, profiling, or any purpose unrelated to the game.

4. Data sharing

We do not sell, rent, or trade your personal data. Data is not shared with third parties, except:

With the hosting/infrastructure provider that runs the game server and database, solely to operate the service.
Where required to comply with a legal obligation.

5. Data retention & deletion

Account and statistics data is retained for as long as your account exists. You can request deletion of your account and associated data at any time by contacting us at the address below; we will delete it within a reasonable timeframe, except where retention is required by law.

6. Security

Passwords are never stored in plain text — only a salted hash. We recommend connecting to a game server that uses wss:// (encrypted WebSocket) rather than an unencrypted ws:// connection whenever possible.

7. Children's privacy

Skirmish is not directed at children under 13, and we do not knowingly collect personal data from children under 13. If you believe a child has provided us with personal data, please contact us and we will remove it.

8. Permissions used by the Extension

Permission	Why it's needed
`storage`	Save your game server address, language, and preferences locally on your device via `chrome.storage.local`.

The Extension does not request access to your browsing data, tabs, cookies, or any other site content.

9. Changes to this policy

We may update this policy from time to time. Material changes will be reflected by updating the "Last updated" date above.
