Trajectory does not collect, store, or transmit any personally identifiable information. All trip and itinerary data entered by the user is stored locally in the browser via chrome.storage.sync and is never sent to our servers. The extension makes outbound requests to Unsplash (unsplash.com) for destination photography and logo.dev for airline logos solely for display purposes within the extension UI. No user data is included in these requests beyond the search query terms (destination names and airline domains) necessary to retrieve relevant images. We do not sell, share, or transfer user data to any third party.
