Update Description:
v2r13 (2003-01-23):
- Security Fix: Secure It erases the clipboard before exiting so that anything stored in the clipboard when Secure It executes is not compromised when Secure It exits.
- Thanks to Mario Chisari for spotting that one!

v2r12 (2003-10-16):
- BugFix: log out when pressing the power key also works on visors.

v2r11 (2003-05-27):
- If you are in a edit view and switches to another application your data in the fields are now saved - the next time you open Secure It you will open up in the edit mode of the saved data (Zdenek Buk).
- Secure It only logs out if the system is powered down when pressing the power key - pressing and holding the power key toggles backlight as it should (Zdenek Buk).
- Hires icons created by Jeroen Witteman.

v2r10 (2003-03-08):
- Fixed a memory bug.
- German version of Secure It (Christian Bolz).
- Moved the Webpage from www.schau.com/palm/sit to www.schau.com/sit.

Powerful, very flexible and reliable it's definitely a great application to store all your sensible data. It only lacks a desktop companion to compete with "best of breed" commercial software in this category. Anyway, thanks for this very nice piece of work, including translation.

This is the program for everyone that wants a really secure storage vault. Settings include an "erase all" data function, if your palm is lost and someone tries to hack your passcode.

A lot of programs out that do what this program does but SecureIt does it better, more intuitively and with the smallest learning curve. Especially like the templates; almost like customizing your fields.
