Just detected a call made by my iPhone seemingly sending my iOS keyboard data to an iCloud server. The domain name icloud-content[.]com is owned by Apple but not the one normally used for syncing iCloud data. The 316 KB of keyboard data is marked as "UserWords"
The data is encrypted and I couldn't get a clue of its content. The only keyboard data that is synced via iCloud is the text replacement dictionary.....
...But there's only one entry on the iPhone that sent this data, it can't make 316 KB.
Apple promises that the processing of keyboard suggestions takes place on-device. So what's the content of this data? Regardless of whether the data is end-to-end encrypted or server-side encrypted, is there a way to turn this off?
iCloud syncs QuickType Keyboard learned vocabulary across devices. The data is end-to-end encrypted. There doesn't seem to be an option to disable it. If you find a way to disable it, share it with us.
It is worth noting that the Text Replacement dictionary is synced without end-to-end encryption. Because when you request a copy of your data, you'll find the dictionary.
