Can a website record your screen?
A website can use a replay tool to show your clicks and scrolling on its pages. To share your whole screen through the browser, you must choose a screen, window or tab in a permission prompt.
Example: a shopping page
You scroll through shoes, open a size guide and click “Add to cart”. A tool such as Microsoft Clarity can turn those steps into a replay that looks like a video of your visit.
Replay tools can hide sensitive details such as form entries. This is called masking. What stays hidden depends on the tool and the website’s settings.
What could someone learn?
A replay may show which products or health pages you viewed. Ask the company which pages use replay, what it saves, who can see it and when it deletes it.
How to check a website
Start with the privacy policy. Look for “session replay” or the names Clarity, Hotjar and FullStory. If you use browser Developer Tools, its Network tab can show whether the page contacts one of these services.
Ask what the company saved and which details it hid. You can also use the website’s privacy controls and your browser’s tracking protection. Save the page address and date if you report a concern.
