This sounds like you want ideas to spin up a crypto pump & dump scheme tbh.

Don’t worry about girls, don’t worry about showing it to girls. Go have fun with your friend and make some good memories doing something goofy.

Like others have noted, for signal do a backup using the built-in feature. Then wipe the apps storage to clear messages.

For SMS/MMS I have usedSMS Import/Export before to transfer that data between devices easily without any issues so it should work as well.

I would also make sure to enable the feature to disable USB when the screen is locked. Just in case you get TSA stopped & they take your device for any reason.

Most cookies don’t store any data themselves. Instead it is a session/device token that tells googles servers what device is connecting and then they look up the data they have about you server side. Cookies can store more than that situationally but that is the most common use.

To get what data Google has on you check out Google takeout and you can get a “full” export of what data has been gathered.

It is amazing! A couple years ago I played through the Metroid series (not every game original/remake counted) and it was one of my top games. It did have one issue IMO, once you get the screw attack there is an expectation that you are familiar with how to use it, which as a new player, took me a very long time to get past. But other than that I loved my time with it & didn’t have any complaints!
