For iPad and iPhone, signing-out of iCloud does not clear all locally stored data - and unless you are very careful when signing-out from iCloud, you stand a very real risk of having your personal and/or sensitive data (such as your Calendar, Contacts and Keychain/Passwords) being merged with the AppleID account that is next used to sign-in.
Before giving away any device that you have used to someone else, you must completely sanitise an iPad or iPhone of all data. The process that you should follow is documented here:

If your data been merged with your Daughter’s AppleID account, there is no easy way to undo the data merge. You must manually remove the data. Each unwanted contact, diary entry, password etc. must be individually deleted.
