+Backing up your Haveno data is crucial to ensure you can retain control over trades, disputes, payment accounts, and funds in case of issues with your machine (e.g. drive failure) or Haveno itself (e.g. critical bugs).
 All Haveno data is stored right on your computer—it's never stored (or even sent) to a central server, so backing it up is your job. We will see data restoration after the backup.

 #### 1.2 While Haveno is closed
 
 When Haveno is closed, you can simply copy the entire data directory and paste it somewhere safe. Find the location of your data directory by clicking on the `Open Directory` button (see screenshot above) or see data directory locations here:

 Use the output to copy and paste the details into new payment accounts in Haveno, paying special attention to make sure each field is copied over with 100% accuracy (including the salt): even a 1 character difference in any field will cause the hash of the payment account to be different, which means aging and signing status will not be restored in the following step.
