10. California Privacy Rights
If you are a California resident, the California Consumer Privacy Act (CCPA) and the California Privacy Rights Act (CPRA) grant you specific rights regarding your personal information. Under these laws, California residents have the right to:
- Know what categories of personal information we collect, use, disclose, and sell
- Request deletion of personal information collected from you

13. Do Not Track Signals
Some web browsers offer a Do Not Track (DNT) signal that indicates a user preference not to be tracked across websites. At this time, our website does not respond to DNT signals because there is no widely accepted industry standard for how to interpret and implement such signals. However, we do honor Global Privacy Control (GPC) signals as a valid opt-out request under California law, in compliance with the CPRA regulations.
We continue to monitor developments in browser privacy standards and may update our DNT practices as industry standards evolve. In the meantime, you may exercise control over tracking through your browser cookie settings or by contacting us directly.
