Privacy Policy vs Terms of Service — What's the Difference?

Most website owners know they need "legal pages" but aren't sure what those actually are or how they differ. Privacy policies and terms of service are two completely separate documents that protect you and your users in different ways — and most websites need both.

Here's the clearest explanation you'll find.

The One-Line Summary

Privacy Policy: Tells users what data you collect about them and how you use it.

Terms of Service: Tells users what rules they must follow when using your website or app.

🔒 Privacy Policy covers...

  • What personal data you collect
  • Why you collect it
  • Who you share it with
  • How long you keep it
  • Users' rights over their data
  • Cookie usage
  • How to contact you about data

📋 Terms of Service covers...

  • Rules for using your site
  • What's prohibited
  • Who owns the content
  • Disclaimer of liability
  • How disputes are resolved
  • Account termination rules
  • Governing law

Which One Is Legally Required?

This is where it gets important:

Privacy Policy — legally required in most cases

A privacy policy is mandatory by law if you collect any personal data from users. This includes:

Additionally, Google Analytics, Google AdSense, Apple App Store, and Google Play Store all require a privacy policy in their own terms.

Terms of Service — legally optional, but strongly recommended

There's no law requiring you to have terms of service. However, without one you have no legal agreement with your users, which means:

💡 Simple rule: Every website should have a Privacy Policy. Any website with user accounts, user content, or transactions should also have Terms of Service.

Real Examples — What Does Each Document Actually Say?

Privacy Policy example

"We collect your email address when you sign up for our newsletter. We use this to send you updates about our products. We share your data with Mailchimp, our email provider. You can unsubscribe at any time by clicking the unsubscribe link in any email."

Terms of Service example

"You may not use this website to send spam, harass other users, or post illegal content. We reserve the right to terminate accounts that violate these rules. All content you submit remains your property, but you grant us a license to display it on our platform."

See the difference? The privacy policy is about your data practices. The terms of service is about the rules of using your service.

Other Documents You Might Need

Cookie Policy

A separate document (or section of your privacy policy) that specifically explains your use of cookies. Required by GDPR if you use non-essential cookies like analytics or advertising trackers.

Refund Policy

Required for e-commerce stores in many jurisdictions. Often included as a section within Terms of Service or as a standalone page.

GDPR Data Processing Agreement (DPA)

Required if you process data on behalf of EU clients as a B2B service provider. Not needed for most consumer-facing websites.

Frequently Asked Questions

Can I combine my Privacy Policy and Terms of Service into one document?

Technically yes, but it's not recommended. Keeping them separate makes both documents clearer and easier for users to find what they're looking for. It's also easier to update one without touching the other.

Where should I put these documents on my website?

Both should be linked in your website footer so they're accessible from every page. Terms of Service should also be linked at checkout or account signup. Privacy Policy must be linked anywhere you collect personal data.

Do my Privacy Policy and Terms of Service need to be written by a lawyer?

No. For most websites, a well-written AI-generated or template-based document is legally sufficient. The content matters, not who wrote it. For complex businesses (healthcare, finance, enterprise SaaS), professional legal review is advisable.

How often should I update them?

Review both documents whenever you add new features, start using new third-party services, change how you use user data, or expand to new countries. At minimum, review annually.
