What Houdini collects
Nothing. It has no server, no account, no analytics, and no tracking.
What it stores
The name, email, phone and city you type into the popup, kept in your browser's session memory (storage.session) only. It is erased when you close the browser. Nothing is written to disk by Houdini.
What it sends
Nothing. Houdini makes no network requests. It only types your own details into a form on the page you're viewing, when you click Fill. You decide whether to submit that form to the website.
Permissions and why
activeTabTo fill the page you're on, only when you click the extension, and only that tab.scriptingTo type your details into that page's form fields.storageTo remember your details until you close the browser.
Houdini never clicks, submits, or logs in for you.
