For example, if you’re browsing with your mobile device, you can enable Booking.com to see your current location or grant access to your contact details – this helps us provide you with the best possible service. You can also open a user account, which allows you to save your personal settings, upload photos, review previous bookings or plan and manage future reservations (all pretty handy stuff). You may participate in referral programs or sweepstakes, and doing this will also mean providing us with personal information.
