Only on your device, inside your browser. There's no account and no server copy. Nobody else can see your pay, including us.
That also means:
Clearing your browser's data or "site data" deletes your records.
Records don't sync between your phone and computer.
Another browser on the same device (Chrome vs Firefox) has its own separate records.
Back up and restore
Go to Settings › Backup & restore and tap Export backup. Keep it somewhere safe, like your Google Drive or email to yourself.
Kompyut reminds you when your last backup is more than a week or two old.
To restore, tap Import backup… in Settings, or Restore from a backup file on the welcome screen of a fresh install.
Good to know. Anyone with your backup file can read your pay records. Keep it private.
Moving to a new phone or computer
On the old device, tap Export backup in Settings.
Send the file to the new device.
Open kompyut.com on the new device and tap Restore from a backup file.
