Privacy policy

Last updated January 26, 2023

1. Introduction

PageVitals ApS ("PageVitals", "we", "us") provides web performance monitoring services ("Software" or "Services"). We are a privacy-first company, committed to minimizing data collection and protecting the privacy of our customers, and their end users. This Privacy Policy describes our practices in gathering, securing, and using application and personal data.

By making web performance data or personal data available to us through our website, Services, or related communication, you agree to the terms of this Privacy Policy and you expressly consent to the processing of your data in accordance with this Privacy Policy.

Our privacy policy depends on which group you belong to:

  • Visitors on who haven't signed up for an account
  • Users of the PageVitals Admin UI (
  • End users visiting a website that uses PageVitals Field Testing script

We'll go through each group in the following sections

2. Visitors on who haven't signed up for an account

We use Field Testing on which is completely anonymous and does not track PII or behavior. You can read more about what data is collected in section 4.

If you give us consent, we will use the chat provider Crisp for providing support and customer success services. You can see the Crisp's privacy policy here

If you give us consent, we will use the session replay tool Mouseflow for improving our website, discovering UX issues and bugs. You can read Mouseflow's privacy policy here

2.3 Data you give us

PageVitals collects your email address if you voluntarily enter it when subscribing to our newsletter, or similar.

3. Users of the PageVitals Admin UI (

3.1 Data you give us

When you sign up for an account or accept an invitation into an existing account, we will collect the following data:

  • Your email address
  • Either an encrypted token from Google or Microsoft if you use them as login provider
  • Or, a cryptographically safe salted and hashed password (using bcrypt)
  • Your name
  • The country of your Internet Service Provider
  • Your profile picture, if provided via Google or Microsoft
  • An account name that you choose
  • Your website domain

4. End users visiting a website that uses PageVitals Field Testing script

When a browser visits to a website that has the PageVitals Field Testing script installed, the following data is collected:

  • The country of the Internet Service Provider
  • The operating system
  • The browser name
  • The device type (desktop, mobile or tablet)
  • Anonymous performance data typically available through the performance.getEntries() array.
  • Technical browser events such as largest-contentful-paint, layout-shift and interaction-to-next-paint, as used by the public web-vitals.js script
  • Note that we immediately discard both the IP address and the User-Agent string at the edge, so this information isn't stored by us (unfortunately it's not technically possible to avoid sending this at all).
  • No cookies are set (or any other similar browser persistence mechanism).
  • No user behavior is monitored, such as mouse or keyboard events.

According to our interpretation of the EU GDPR law, the EU ePrivacy Directive and CCPA, the above doesn't require consent. Even though we very temporarily get access to the end user's IP address before we discard it, this alone isn't enough to constitute PII since we have no lawful means of accessing personal data held by the end user's ISP, and we are not reasonably capable of linking this data to particular consumer or household.

Note that despite the above, it's the responsibility of the PageVitals client to make sure local law is followed.

5. How We Protect Your Information

PageVitals uses a variety of security measures to maintain the safety of your Personal Data. All transmitted data is using Transport Layer Security (TLS) version 1.2 or above. Passwords are salted and hashed using the recommended algorithms. Payment information is sent directly to Stripe and never stored on our platform.

PageVitals will never sell your personal data to anyone. Your personal data is only accessible to PageVitals employees, contractors, and our service providers that require the data in order for our Software to operate.

6. Cookies
