TimeShift keeps the minimum it needs to plan your trips. Here is all of it.
What we keep
Your email address, used only to send one-time sign-in links. The trips and itineraries you enter. Questions you ask the Jetlag Coach. Nothing else — no ad trackers, no analytics profiles, and nothing is sold or shared for marketing.
Where it lives
Trip data is stored in a Postgres database hosted by Supabase. Sign-in emails are delivered by Resend. The site runs on Vercel. When you ask the Jetlag Coach a question, that question and the trip it concerns are sent to Google’s Gemini API to compose the answer — coach requests are the only data that goes anywhere else. Sign-in links are single-use and expire in 15 minutes.
Your data, your call
