What Lindy does with your messages
Read from its published policy on 2026-09-08, and quoted rather than paraphrased. It says it does not train 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 not |
|---|---|
| Data of people who never signed up | Not addressed |
| If you cancel | Not addressed |
| Model providers named | None named |
| Who carries the messages | Not disclosed |
| Where to report a hole | Published |
| Jurisdiction | Not stated |
In its own words
“Your data is never sold and never used for training.”
What it does not answer
The policy is silent on data of people who never signed up, if you cancel, model providers named, who carries the messages 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.
