How to mask elements

When you record a session or sample a heatmap Extellio may record user-sensitive data with is displayed on your website. To avoid recording personal data you can mask elements from being recorded by adding the data-matomo-mask attribute around the element in the website’s code.

You can mask individual elements like this: 

<span data-matomo-mask>Firstname lastname</span>

or you can mask a set of elements

<div data-matomo-mask><p> <span>Firstname</span><span>Lastname</span> </p> </div>

Before sending the data to Extellio, any masked content will have each character replaced by an asterisk (*). Additionally, content displayed in the title, alt, label, or placeholder attributes will also be masked.

The following fields are always masked in session recordings: 

• Any input field with the type password, tel, or email.

• No value is recorded for hidden form elements.

• When a user enters between 7 and 21 digits in sequence, Extellio assume it is a credit card number or similar and mask it.

• When a user enters an @ symbol, Extellio assume it is an email address and don't record it.

• Form fields within iframes won't be recorded at all.

• Extellio ignores any form field when it has an id, name, or autocomplete with one of these values (any dashes, underscores, or whitespace in the name are ignored):
