Is Rellenator safe?

Clean risk

Rellenator sends saved profile text and detected form-field labels to OpenAI when filling forms.

When you click the extension to fill a form, Rellenator scans visible form fields and accessible iframes for each field's type, name, and label. It combines that field context with the selected saved profile or typed user information and sends one request per field to OpenAI to generate the values it fills into the page.

Where it sends data

Destinations our analysis observed Rellenator contacting. Sending data somewhere is not a finding on its own - an extension that syncs your settings has to talk to its own server - but it is where your data can go, and who else it goes to.
