You need to review and update your privacy policy regularly. At a minimum, you should review your privacy policy at least once a year to make sure it reflects your current data processing activities.
Privacy policy reviews are also important when you’re launching a new or updated product or service, using data in a new way, or sharing data with a new partner or vendor.
Some privacy laws require updates after a specific period of time. For example, the California Consumer Privacy Act (CCPA) contains an explicit requirement that businesses subject to the law must update the information in their privacy policy or policies at least once every 12 months.
