Cookies may be "session cookies" (which expire when you close your browser) or "persistent cookies" (which remain on your device until they expire or are deleted).
Similar technologies include web beacons, pixels, local storage, and SDKs that serve analogous purposes. References to "cookies" in this policy include these technologies where applicable.

2.3 Analytics Cookies
These cookies help us understand how visitors interact with our website and Service by collecting and reporting information about usage patterns. We use this data to improve our platform, optimize performance, and develop new features. We use privacy-preserving analytics tools that do not track users across third-party sites.
