They are essentially a keylogger when the 'cloud' service is turned on. It uploads everything you type but tries to detect password fields and avoid them. They insist their security and cryptography is quality, but we've heard that a lot recently.

Their lack of an obvious business model is a bit worrying.

They do send raw unprocessed texts? Thanks for warning.

From my understanding, unless some really tricky and CPU-savvy math's in works, it probably would be more efficient to update language model on-device then push the change. Not only it would somehow avoid (not really, but at least obscure a bit) revealing the exact typed texts, but also lower the necessary server-side processing.

The text prediction still works fine locally without the cloud feature. The data gathering is probably to refine their algorithms. Which I'd expect would include raw text input. Which in a surveillance sense is a bit scary, someone seeing your unfinished thoughts or pre-self-censorship messages.
