Cara McGoogan, writing for The Telegraph:

A British keyboard app that uses artificial intelligence to predict the next word you want to write has suspended part of its service after users reported receiving predictions meant for other people, including email addresses and phone numbers.

After installing SwiftKey on a new device, one user was shocked when the app suggest she use a stranger’s email address. Another reported getting predictions in a language they’d never spoken.

Thankfully, the ability to sync the app on new devices has been temporarily disabled. But this certainly leaves me questioning whether it’s worth the risk to use third-party keyboards at all.
