What Are Cookies?

Cookies can be used to remember preferences, maintain website functionality, measure performance, support security, and deliver or measure advertising.
Some cookies remain only for the duration of a browser session. Others may remain on your device for a specified period or until you delete them.

- Local storage
- Session storage
- Pixels
- Tags
- Scripts

They may be used to remember preferences, record consent choices, measure usage, or support advertising functions.
