If you have not enabled feature Flags yet, enable Feature Flags
To do this, go to the About screen, and tap on the “PathCheck GPS” heading 10 times.
Under More / Feature Flags enable “Import from Google”
(the import doesn’t really come from google, the naming is historical - I’d lie like to fix, but this is what it is for now)
Now on the More screen, press the “Import past locations” button
Scroll down and press “Import from URL”
Enter the URL of some JSON data (see below), for example
https://diarmidmackenzie.pythonanywhere.com/location-data?latitude=51.5&longitude=-0.144
Press the confirmation button on the keyboard (green check on Android, not sure on iOS), then press Add.
The locations will be added to your local location database.
Note that hashes (needed for Exposure Notification Detection) will only be included if the JSON data provided included hashes. The App does not generate these hashes itself.

There is no way to delete that data, other than explicitly deleting the app’s data (which will reset everything and require you to repeat onboarding), or a complet uninstall/reinstall of the app.
AFAIK there is no mechanism in the app to stop you overloading the database with far too many points, either from one upload with too many points, or from multiple uploads in sequence. If you put far more than 4000 data points in the app, it might start to behave oddly.
At the moment, Safe Places does not perform well with hundreds of location data points, and it is really really slow with 4,000 data points. This is reported as PLACES-492 - we understand the problem and are working on a fix, but until that fix is rolled out, you might want to keep data sets down to 1-2 days.
As per limitation above, the tool does not import hashes into the phone database. So it is not yet suitable for realistic testing of exposure notification performance with a full data set. (in the short t
