# Privacy and security

## Your account's privacy in the chat

Support (including Jake, our AI agent) will never confirm or deny to
anyone whether an email address has a 1Lookup account. Before any
account details are shared in chat, we verify you with the email on the
account **plus the last 4 digits of the card on file**. That is the
most we will ever ask for: never a password, never a full card number,
never a full API key.

If you paste a secret (an API key, a password) into any chat by
accident, treat it as exposed: rotate the API key on the API Keys page
or change the password.

## Your data

- We store your account details and your lookup history (inputs and
  results) so you can re-download results. Data is stored encrypted on
  AWS.
- Want your data deleted? Write to us in the chat or at
  support@1lookup.io; deletion requests are honored, except records we
  must keep for legal and billing reasons.
- We do not name the individual upstream sources behind products; data
  comes from licensed commercial sources and live network checks.

## Acceptable use

1Lookup is for legitimate business contact and verification purposes.
Using it to stalk, harass, or defraud people is against the terms and
gets an account closed.
