Session replay lawsuits, explained for site owners

Thousands of websites have received wiretapping lawsuits or demand letters for running session replay and tracking pixels — under a California law written in 1967.

The analytics layer that watches what visitors do on the page - heatmaps, replays, funnels, frustration signals - rather than counting how many arrived. What it covers, and what the security industry means by the same phrase.

How to analyze a heatmap

The colors are the easy part. Reading a heatmap well means checking the sample, knowing the scanning patterns behind the hot spots, splitting by device before concluding anything - and knowing when the map has told you all it can.

How to analyze session recordings

A replay tool piles up hundreds of recordings a week, and watching them in order teaches you nothing. The workflow that extracts answers: filter to the sessions that matter, watch a handful with one question, stop when patterns repeat.
