Your data is absolutely private
Trilobite Solutions understands that the privacy of your data is paramount. Australian Geology Travel Maps writes trails and locations data to your phone/tablet only. None of your data is copied behind the scenes to the internet. None of your data is visible to Trilobite Solutions. The only way for anyone (including Trilobite Solutions) to access your marked locations and trails is to have your device in their hands, or for you to share your data (as KML, CSV or GeoJSON) and send it to them.
Back up your data
As mentioned above, your locations and trails are only stored in one place – on your phone/tablet. This is not a safe long-term storage area. You may lose or damage your phone, it might malfunction, or you may unwittingly uninstall Australian Geology Travel Maps, and consequently lose all of your marked locations and trails. Regularly share your locations and trails as CSV and put them into an email sent to yourself. If you do not trust your email provider, then you can instead share the CSV with DropBox or some other internet-based storage system, and save the .csv file there.
On Android devices you can backup your data without involving the internet. Install a file manager, such as https://play.google.com/store/apps/details?id=com.alphainventor.filemanager&hl=en_AU , share locations or trails as CSV, open with the file manager, and save to your device. Then copy the .csv file to your computer via your USB charging cable.
Restore your data
At any time in the future that you lose your phone or lose your data for some other reason, you can install Australian Geology Travel Maps on a phone or tablet, and import your .csv files.
