To clarify: it's not included with PalmOS; it's 3rd-party software.

The "private" flag in PalmOS is advisory only. As has been noted in previous
discussions (most notably L0pht/@stake's PalmOS password recovery discovery),
the Palm platform is not designed to be secure. Physical access means access
to all its data.[0] So there's not much new about Tiny Sheet apparently not
following the guidelines. It's just another example of the limitations in PalmOS.

If you want to protect data stored on a PalmOS device, encrypt it. Hmm, I'd
be interested to see some work on PalmOS memory attacks, e.g. after you've
run a crypto app, can you run another app that scours the device's memory
for information left behind, e.g., passphrases or decrypted keys?
