Location History Visualizer

Welcome to Location History Visualizer, a tool for visualizing your collected Google Location History data with heatmaps. Don't worry—all processing and visualization happens directly on your computer, so rest assured that nobody is able to access your Location History but you... and Google, of course.

To start off, you'll need to go to Google Takeout to download your Location History data: on that page, deselect everything except Location History by clicking "Select none" and then reselecting "Location History". Then hit "Next" and, finally, click "Create archive". Once the archive has been created, click "Download". Unzip the downloaded file, and open the "Location History" folder within. Then, drag and drop Records.json from inside that folder onto this page. Let the visualization begin!

Alternatively, select your Records.json file directly:

Processing data...

Waking up...

This may take a while... sit back, get a cup of tea or something.

Why does it take so long? Depending on how long Google's been tracking your location, you may have hundreds of thousands of [latitude, longitude] pairs, every one of which must be loaded, analyzed, and plotted. That's a lot of dots.
