TimelineSnap Turns Google Timeline Exports Into a Private Day-by-Day Map

Field notes

The page frames the product around a single Google Timeline JSON export rather than an account integration. Its visible intake checks the file type, MIME type, empty-file status, and a 50MB limit; the described output is organized by date, with movement and place records shown in sequence and replayed over a map. The site says source data remains in the browser, while separately acknowledging that external map tiles can receive viewport requests. Full format parsing is presented as a later development step.
