No, not all websites need a privacy policy. A privacy policy is a document that explains how  websites collect, use, and share personally identifiable information (PII). Only websites that collect PII and are subject to certain privacy laws need a privacy policy.

PII is information that can be used by itself, or in conjunction with other data, to identify a person. If your website collects PII like any of the following, you may need a privacy policy:

  • Names
  • Social Security numbers
  • Physical addresses
  • Email addresses
  • Birthdays
  • Biometric information

If you collect PII, you should have a privacy policy to comply with different privacy laws of the world.
