Bulwarden is a small co-op browser game. This policy explains what data the game handles and why. By playing, you agree to this policy.
You can play without signing in. In that case the game stores a random, anonymous ID in your browser's local storage to remember your progress (scores, cosmetics, in-game currency) on that device. This ID is not linked to any personal identity. No account, email, or personal information is required to play.
Signing in is optional and is used only to save your progress across devices. If you sign in, we receive from Google your account identifier, email address, and display name. We store these on our own server solely to identify your account and sync your game progress. We never use your email for marketing and never sell or share it.
Signing in is optional and is used only to save your progress across devices. If you sign in, we receive from CrazyGames your account identifier and username. We store these on our own server solely to identify your account and sync your game progress. We do not receive your email address.
Your chosen in-game name, best scores and waves, cosmetic unlocks, and in-game currency ("Salvage"). If you are signed in, this data is tied to your account; otherwise it is tied to your anonymous device ID.
Your chosen in-game name and your score may be displayed on public leaderboards inside the game.
If you send feedback through the in-game button, we store your message and the name you entered, and forward it to our private Discord channel so we can read it. Please don't include sensitive personal information in feedback.
When you connect, your IP address is processed temporarily in memory to prevent abuse (rate limiting and connection limits). It is not stored in our database.
Bulwarden shows no advertisements, uses no advertising or analytics trackers, and does not sell your data.
This version of the game is hosted on CrazyGames and shows advertisements served by them. We do not run our own advertising or analytics trackers and do not sell your data. See CrazyGames' Privacy Policy for how their advertising works.
Guest data lives in your browser — clearing your browser's site data removes it. If you are signed in, open the Account screen in the game and use Request data deletion to ask us to permanently delete your account and all stored progress. Requests are processed manually.
Bulwarden is not directed at children under 13 and does not knowingly collect personal information from them.
For data deletion, use Request data deletion on the Account screen (when signed in). For any other questions, use the Feedback button in the game.
We may update this policy. The "Last updated" date above reflects the current version.
