Cookie Policy
Last reviewed 12 August 2026. There are no tracking cookies here — only a few local entries that keep the arena usable.
What we actually use
Strictly speaking, Boss Rush Perk Matrix does not set traditional cookies at all. It uses your browser's local storage, which stays on your device and is never sent with page requests. We describe it as a cookie policy because that is the language most people expect.
The entries in full
| Entry | Purpose | Lifetime |
|---|---|---|
| brpm.age | Remembers your 18+ confirmation | Until cleared |
| brpm.cookie | Remembers your choice on this banner | Until cleared |
| brpm.roster | Stores handles created on this device | Until cleared |
| brpm.active | Keeps you signed in between pages | Until cleared |
Essential versus optional
Every entry above is essential to how the site functions. Choosing "Essential only" on the banner changes nothing about what is stored, because there is no optional analytics or advertising layer to switch off. We keep the choice visible so the difference is explicit rather than assumed.
Third-party requests
Google Fonts serves the typefaces used on the site, and the embedded games load their own assets from this domain. Neither is used to build a profile of you.
