Buyer questions
Questions buyers actually ask
Does my Timeline file leave the device?
No. The browser reads, parses, animates, and records the file without sending the JSON to our server. By default, real-map tiles are requested from CARTO, which receives map-tile areas and ordinary network data, not your file. Turn on Privacy mode for a locally drawn map with no tile requests.
Which Google Timeline formats work?
The parser recognizes Records.json, timelineObjects, semanticSegments, Location History arrays, and generic latitude and longitude records with timestamps.
Is Timeline Visualizer free?
Yes. The visualizer is free, runs entirely in your browser, and needs no account, app install, or upload.
Is this an official Google product?
No. Timeline Visualizer is an independent tool and is not affiliated with Google.
