Private Cache was developed to help you protect important information from prying eyes. The password and important information are saved in a protected format. Note that encryption is not used but it is believed that the protected format is sufficient to protect information from the casual snoop.
Private Cache replaced Pocket Cache (trademark issue). If you are a Pocket Cache user, you can use the same password. Data is preserved.
It is a good idea to back up My Secret Info data in a separate file before upgrading to a new version.
