Google location timeline data is now device local - know issue with device export to JSON

[hossain-khan]

Due to recent changes, location data is now moved to device.

User can enable cloud sync for the location data, but at the moment sync is full backup and they are encrypted.

Export from device does not seem to follow the Google Take out format either.

I have posted about these issues at https://support.google.com/maps/thread/293710908/export-device-local-location-timeline-data-fails?hl=en

No action is required, this is just FYI post. Issue can be closed.

Since Google move timeline data to device and export now has new JSON structure. But there is no document/reference about this anywhere.

It seems like they have fixed the issue. Now the timeline data can be exported from the device.

Here is JSON structure of the export.

{
    "semanticSegments": [
        {
            "startTime": "YYYY-MM-DDTHH:MM:SS.000-04:00",
            "endTime": "YYYY-MM-DDTHH:MM:SS.000-04:00",
            "timelinePath": []
        }
    ],
    "rawSignals": [
        {
            "activityRecord": {}
        },
        {
            "position": {}
        },
        {
            "wifiScan": {}
        }
    ],
    "userLocationProfile": {
        "frequentPlaces": [
            {
                "placeId": "abcdefghi",
                "placeLocation": "123.123°, -456.456°",
                "label": "HOME"
            }
        ]
    }
}

I've created mini PHP web app for view these timeline data ( https://github.com/Rundiz/personal-maps-timeline ), I hope you like it.

I exported my timeline data (with data points starting from 2013) and wrote this TypeScript interface based on it. I'm assuming SemanticType/ActivityType/TravelMode can have other values, but these are the ones I saw in my data. Perhaps a JSON schema can be generated from this interface and added to the schemas in this repo?
