Privacy Policy

Last updated: June 6, 2026

HotelXray ("the extension") is a Chrome and Firefox browser extension that overlays award and cash availability data on Hyatt hotel pages. This policy explains what data we collect and how we use it.

What we collect

HotelXray collects limited, anonymous usage data to improve the service:

• Feature usage events — when you toggle a metric (Points, Cash, CPP, SUA), switch room types, or change currency. No identifying information is attached.
• Booking signals — when the extension detects that a Hyatt booking has been confirmed on your browser, it records the hotel property, check-in/check-out dates, number of rooms, whether the booking was paid with cash or points, and the booking amount. We use this only in aggregate, to measure how many bookings and what total booking value the extension helps generate and to surface popular hotels and dates to users. No personal details (name, confirmation number, payment-card or account information) leave your browser.

We do not collect your name, email address, Hyatt account details, payment information, or any other personally identifiable information.

Local storage

Your preferences — such as selected room type, visible metrics, currency, and tax toggle — are saved locally in your browser using chrome.storage. This data never leaves your device.

The extension also generates a random identifier (UUID) per installation to associate events from the same device. This ID is not linked to your identity and cannot be used to identify you personally.

Session recovery

Hyatt's website has a long-standing bug where its pages sometimes render blank in Chrome. When HotelXray detects this, it can fix the page by clearing Hyatt's session cookies and reloading — but only with your consent. The first time it happens, HotelXray asks you, and you can either fix it once or opt in to do it automatically from now on. No other cookies are touched, and nothing about your cookies is sent off your device.

How we use the data

Anonymous usage events and booking signals are sent to HotelXray's servers (api.hotelxray.app) solely to understand how the extension is used and to improve the product. We do not sell, share, or monetize this data with third parties.

Data retention

Anonymous event data is retained for up to 24 months and then deleted.

Third parties

HotelXray does not use third-party analytics services, advertising networks, or trackers. All data is sent only to api.hotelxray.app, which we operate.

Limited use

The use of information received from Google APIs will adhere to the Chrome Web Store User Data Policy, including the Limited Use requirements.

Affiliation

HotelXray is an independent tool and is not affiliated with, endorsed by, or sponsored by Hyatt Hotels Corporation. "Hyatt" and all related marks are trademarks of their respective owners.

Children's privacy

HotelXray is not directed at children under 13 and does not knowingly collect data from them.

Changes to this policy

We may update this policy as the extension evolves. The "Last updated" date at the top will reflect any changes. Continued use of the extension after changes constitutes acceptance of the updated policy.
