However, Apple did provide a safety mechanism, in the form of an "Allow Full Access" setting for each individual third-party keyboard you install. If you do not explicitly enable "Full Access" for a keyboard, it will be limited in certain ways to prevent malicious behavior. In particular:
- It cannot access the network.
- It cannot access the clipboard (cut/copied text).
- It cannot play key clicks.
Our interests are in providing the best possible typing experience available on your iPad, and nothing else. But no need to trust us -- just leave "Full Access" off if you are concerned.
For further information, please refer to Apple's documentation on the matter:
