How u do that? I have TB...
"4. How to use the multi-user “data profiles” feature (Pro version, TB 4.0.0 or above):
Important note: This feature is able to overcome the single-user nature of Android to some extent, and is (of course) awesome, but it will not turn your Android OS into a fully fledged multi-user entity. The feature is meant for apps that don’t use background services and don’t sync their data with a server. Ideal candidates are games, note taking apps, prank apps and many others. Itmay also work with some apps/games that access online services, as long as you use a different online account on each profile. Don’t use this feature with system stuff such as SMS/MMS. If you’re unsure about an app, feel free to try it in multi-profile mode with unimportant data for a while.
Create the data profiles you want:
In the Overview screen hit “Switch profile” then “Create a new data profile”.
If your goal is to have separate “Angry Birds” high scores, repeat the previous step to create one profile per player.
Click on “Switch profile” and activate the profile that matches your current data. For example, if you played the game already, you’ll want to activate your own profile now, so that the current data gets assigned to that profile in the next step.
Switch to the apps list
Make the app(s) multi profile aware. For each app:
Long-click on the app
Click on “Enable multiple profiles for this app”. Your current data for that app will be moved into the profile you activated in the previous step.
Create a profile switching widget (optional):
Hit the “HOME” button
Long-click on the background
Click on “Widgets”
Choose “Titanium Backup (Data Profiles)”.
The widget is on your background now. Every time you want to switch the active profile, just click on the widget."
