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.
