Cookie Policy
Last updated: September 29, 2026
1. Cookies and browser storage
Tensor Wave Inc., incorporated in Ontario, Canada, operates buster.games. Cookies are small values saved by your browser and sent with website requests. Local storage and IndexedDB store preferences, saves, or cached game files on your device. This policy describes their use alongside our Privacy Policy.
2. Storage used by the portal
| Storage | Purpose | Duration |
|---|---|---|
| Better Auth session and sign-in cookies | Authenticate you and protect sign-in. Names can include a secure prefix and better-auth.session_token. | Session token: 7 days, with renewal during use. Other sign-in cookies have their own expiry. Signing out ends the session. |
| buster_vid | Assign a guest browser identifier for portal play features. | 400 days, unless cleared earlier. |
| buster_played | Remember recently played games for rating eligibility. | 24 hours; refreshed when play is recorded. |
| theme in local storage | Remember your light or dark theme. | Until changed or cleared. |
| Google Analytics cookies, such as _ga and _ga_* | Measure website sessions and activity using GA4 identifiers. | Determined by Google and our configuration; may be refreshed on later visits. |
| Advertising cookies and identifiers | AdSense and its partners may serve, personalize, and measure ads. | Varies by provider and settings. |
Sign-in cookies support account features. Guest play and rating records also use identifiers and an IP-derived value on our servers; clearing cookies does not delete those server records. Analytics and advertising are additional uses, not requirements for signing in or saving progress.
3. Storage used by games
Embedded games can save settings and progress in local storage or IndexedDB and may contact their own servers. Storage varies by game and origin. Tensor Wave games are covered by our Game Privacy Policy; other games have their developer’s notices. Clearing storage may erase guest progress.
4. Google measurement and ads
The current portal loads Google Analytics 4 on its pages and Google AdSense code on eligible pages. Google or advertising partners may use cookies and identifiers to recognize visits and serve or measure ads based on previous visits to this and other sites. For details, see how Google uses information from partner sites and Google’s cookie information.
5. Your controls
Your browser can block or delete cookies, third-party storage, and other site data. You can sign out to end an account session and clear site data to remove local saves. Blocking sign-in storage may prevent account features from working.
You can manage Google ad personalization in My Ad Center, use the Google Analytics opt-out browser tool, and use browser tracking protections. These controls have their own scope and may not remove information already collected.
The portal does not currently have a separate cookie preference panel or an automatic Global Privacy Control integration. This policy does not treat a visit as consent where explicit consent is required. Contact hey@tensorwave.co to exercise applicable privacy rights or ask about storage.
6. Changes and contact
We will update this page when storage or controls change. For questions, contact Tensor Wave Inc. at hey@tensorwave.co.
