Short version: LinkFill stores your profile data (LinkedIn URL, portfolio, etc.) locally on your device using Chrome's sync storage. We do not collect, transmit, or sell any of your data. Ever.
LinkFill stores only the information you manually enter in the Settings page: your LinkedIn URL, portfolio URL, GitHub URL, phone number, and email address. This data is stored in Chrome's built-in sync storage (chrome.storage.sync), which means it may sync across your own Chrome browsers if you are signed into Chrome.
We do not collect any data. We do not send any data to external servers. We do not track your browsing activity. We do not use analytics or third-party SDKs. We do not sell, share, or transfer your information to anyone.
storage — to save your profile data locally on your device.
activeTab / scripting — to detect and fill form fields on the page you are currently viewing. LinkFill only activates when you click the "Fill this page" button.
host_permissions (all URLs) — required to run on job application sites like Greenhouse, Workday, and Lever, which are hosted on many different domains.
You can delete all your stored data at any time by opening LinkFill Settings and clearing the fields. You can also uninstall the extension at any time, which removes all stored data.
