You can store your notes locally by pasting them in your Private Bins. Optionally, you can drop your notes in the Public Bin so the whole world can follow your bin and see your notes regularly.
1. From the menu, select, 'Public Bin'
2. Select 'Online' mode in the switcher
3. Now whatever you bin, gets saved in the cloud.
If you select 'Local Bin', whatever you type, gets stored in the phone.
