<title>JS Safe - the leading localStorage based safe solution with advanced obfuscation technology</title>
<!--
Advertisement:
Looking for a hand-crafted, browser based virtual safe to store your most
interesting secrets? Look no further, you have found it. You can order your own
by sending a mail to [email protected]. When ordering, please specify the
password you'd like to use to open and close the safe and the content you'd
like to store. We'll hand craft a unique safe just for you, that only works
with your password of choice and contains your secret. (We promise we won't
peek when handling your data.)
