What we know about your conversations.

Everything ChatVault captures — conversations, messages, tags, prompts, attachments — stays in the browser on the device where the extension is installed. Nothing is uploaded. Nothing is mirrored anywhere remote.

You can wipe all of it from the extension settings, or by clearing site data for the extension in your browser. There is no "deletion request" form because there is nothing for us to delete on our end.

No accounts. No emails. No telemetry. No analytics SDKs. No 'anonymous usage data'. No crash reporters that phone home. We don't operate any backend of our own for the extension to send data to — everything stays between your browser and the AI platforms you were already using.

Two paths get conversations into the local store. The first is passive reading — when you open a chat on a supported platform, the extension parses the response your browser was already going to receive and writes it locally. That's still where most captures come from.

The second is active sync. To catch older threads and messages that land while a tab is in the background, ChatVault periodically calls the same APIs the platform's own UI calls — reusing the cookies and tokens from your already-logged-in session. It only talks to the platforms you're already signed into (OpenAI, Anthropic, Google, DeepSeek) and the content-delivery hosts those platforms use to serve their own images and files. It does not synthesize credentials, and it does not talk to any backend we operate (we don't operate one).

It doesn't run on unsupported sites and doesn't read input you haven't sent. The extension does not bundle analytics, telemetry, crash reporting, license checks, or any update server of its own. The complete list of domains it is allowed to contact is the host_permissions block in the extension's manifest — you can audit it there before installing.

The AI platforms themselves (OpenAI, Anthropic, Google, DeepSeek) handle your conversations on their own terms — those terms are between you and them, and they're responsible for that data on their side. ChatVault does not change those terms; the local copies the extension keeps are independent of whatever the platforms store. The same applies to the content-delivery hosts those platforms use to serve images and files.

ChatVault is an independent project. It is not affiliated with, endorsed by, sponsored by, or otherwise connected to OpenAI, Anthropic, Google, DeepSeek, or any of the AI platforms it interoperates with. The names, marks, and logos of those platforms belong to their respective owners; they are referenced here only to identify which platforms ChatVault can capture from.

ChatVault runs in your browser and makes its requests under your already-logged-in session, from your device. Whether to use it on a given AI platform — and whether that platform's terms of service permit this kind of automated access — is your decision as the account holder.

We can't evaluate that trade-off for you, and we can't help if a platform restricts, downgrades, or suspends your account. If you're unsure, read the platform's terms before relying on the extension, and only enable ChatVault where you've decided the trade-off is acceptable for your own use.

The extension is distributed "as is", without warranty of any kind, express or implied, including but not limited to warranties of merchantability, fitness for a particular purpose, or non-infringement. To the maximum extent permitted by applicable law, the maintainers are not liable for any data loss, account issues, lost profits, or other consequences arising from installing, configuring, or using ChatVault. If the extension fails to capture something or stops working after a platform changes its API, the most we can do is try to address it in a later version.

This page describes the product as it exists in the current version. If the product changes — especially in ways that would broaden what data is processed (for example, server-side sync, a paid tier, or any new external service) — we will update this page and the 'Last updated' date at the top. For material changes we will also surface a note in the extension or on this site. Continued use after such updates means you accept the revised policy.
