What Kachi does with your messages
Read from its published policy on 2026-09-06, and quoted rather than paraphrased. It says it trains on your conversations. It does not say which company actually carries your messages, which puts it with the majority: only 9 of 41 do.
What the document says
| Trains on your conversations | States it does |
|---|---|
| Data of people who never signed up | Addressed |
| If you cancel | Account data deleted within 30 days |
| Model providers named | None named |
| Who carries the messages | Not disclosed |
| Where to report a hole | No route published |
| Jurisdiction | Not stated |
In its own words
“training and improving our own models on conversations and outcomes”
“You may mention people who don't use Kachi. We store what you tell us about them in order to serve your relationships”
What it does not answer
The policy is silent on model providers named, who carries the messages, where to report a hole and jurisdiction. Silence is not a denial, and it is not a promise either: a document that does not address the people in your group thread has not agreed to anything about them.
Back to the Kachi listing, or see every policy in this directory read the same way, where 9 of 41 name who holds your messages and the rest do not.
