Privacy in AI Chat Analysis: What to Ask Before You Upload

A checklist for vetting any tool that reads your private messages — retention, training, and subpoena posture.

The trust ask is enormous

Handing a year of personal messages to a piece of software is one of the largest trust asks in consumer software. Before uploading anywhere — including here — ask the same four questions of every tool.

1. Retention

Does the service store the transcript after the report is generated? For how long? Chat Recap AI holds the parsed data in memory only, discards it when the report is rendered, and does not persist the raw transcript.

2. Training

Is your data used to train the underlying model? This is the single most important question. 'We may use your data to improve our service' usually means yes. The only safe answer is an explicit no, written into the privacy policy.

3. Third parties

Does the transcript get shipped to a third-party LLM API? If so, what is the retention policy of that third party? A tool can have a strict no-retention policy itself but leak data to an upstream API that retains it for 30 days.

4. Legal posture

Would the service hand over your data to law enforcement on request? Most would, legally, if they have it. The defense here is not policy — it's not retaining the data in the first place.

Default to tools that keep nothing

The strongest privacy guarantee is one that doesn't require you to trust the provider. Tools that process in-memory and store nothing can't leak what they don't have. That's the standard worth holding out for.
