Unfortunately, this app cannot be operated from a computer.
However, you can export your data and use it with other services.
Data export is part of the paid Premium Service.
Open the app, tap "Settings" at the bottom right, tap "Premium (No Ad)", and purchase the Premium Service. Then "Export Data" near the bottom of the Settings screen becomes available for exporting your data.
When you tap "Export Data", your diary entries are saved in the file format you choose (HTML or TXT), together with their attached photos, and everything is exported as a single compressed Zip file.
HTML files display your photos together with the text, and they are easy to view and print in a computer browser.
You can send the Zip file by email, save it to the Dropbox app, transfer it to a PC via Bluetooth, and share it in many other ways.
The Premium Service is a paid upgrade, but we hope you will consider it.
