I was just trying to charge my phone from someone's Mac and just hit 'trust this computer' without thinking. I am scared that it would've synced immediately so they have access to my photos, notes, etc. I didn't open the MacBook just trying to charge my phone nothing else. Does it sync right away as soon as I hit trust this computer so they have access to all my data? If so, how do I delete or untrust it?
Trusting a computer will only allow for sync and will not sync through iTunes unless you click on sync or sync over WiFi enabled. See the pic below.
However, don't plug in your device in Airports and Public places through third-party cables and trust the device. Beware of Juice Jacking. (Especially in India)
If you don't want to trust a computer or other device anymore, reset the Location & Privacy settings on your iPhone, iPad, or iPod touch. Go to Settings, then tap General. Tap Transfer or Reset [Device]. Tap Reset, then tap Reset Location & Privacy.
