## Personal Data

You will find below an exhaustive list of all data being collected. In particular, **potential** Personal Data would be:

1. Into the **HTML content** that is sent for a small fraction of our visitors. Solutions to prevent this from happening:

   * Remove some sensitive content ([this chapter explains how](https://docs.contentsquare.com/en/web/personal-data-handling/#remove-contentpersonal-data-from-the-collected-html))

   * Totally deactivate this for all users (some features may then be unavailable like Session Replay or retroactive background; ask your Account Manager)

2. Into **Custom Variables** sent to our servers (to prevent this from happening, make sure that the values that you wish to collect could not be linked to one individual)

## What is not collected

* We don't collect the values of form fields
* We don’t collect what the user types in
* We remove every email-looking string in URL, Custom Vars, Dynamic Vars and Session Replay before they are sent to our servers

Warning

This does not apply to Voice of Customer capabilities designed to collect user feedback.\
See [Voice of Customer](https://docs.contentsquare.com/en/web/voice-of-customer/).
