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.
