HotelChrono — Renovation Score · last updated 24 June 2026
What the extension does
The HotelChrono extension detects the hotel name shown on a supported travel page (Booking.com, Google Hotels, Expedia, Hotels.com, TripAdvisor, Agoda, Kayak) — or the name you type into its popup — and looks it up in the public HotelChrono API to show that hotel's Chrono Score and renovation history.
Data we collect
None. The extension does not collect, store, sell or share any personal information. It has no accounts, no analytics, no advertising and no tracking cookies. It keeps no history of what you browse or search.
What is sent, and where
To return a score, the extension sends only the detected or typed hotel name to the HotelChrono API (hotelchrono.com/api/v1). No URLs you visit, no identifiers and no personal data are transmitted. The request is used solely to answer that one lookup and is not used to build any profile of you.
Permissions
The extension runs only on the supported travel sites listed above (to read the visible hotel name) and connects only to hotelchrono.com. It requests no access to your other tabs, files, location or accounts.
