"We may use the information we collect across our services and across your devices for the purposes described above. Depending on your account settings, your activity on other sites and apps may be associated with your personal information in order to improve Google's services and the ads delivered by Google."

Google links user activity across all its services, third-party sites using Google services, and across multiple devices to build unified profiles for ad targeting and personalization.

"Depending on the products you're using and settings you choose, Google may use different types of location information to help make some services and products you use more helpful. These include: GPS and other sensor data from your device, IP address, Activity on Google services, such as from your searches or places you label like home or work, Information about things near your device, such as Wi-Fi access points, cell towers, and Bluetooth-enabled devices."

Google collects location data from multiple sources including GPS, IP address, WiFi access points, cell towers, and Bluetooth signals, enabling comprehensive and continuous location tracking.

"The information we collect includes unique identifiers, browser type and settings, device type and settings, operating system, mobile network information including carrier name and phone number, and application version number. If you're using an Android device with Google apps, your device periodically contacts Google servers to provide information about your device and connection to our services. This information includes things like your device type and carrier name, crash reports, which apps you've installed."

Google collects broad device data including unique identifiers, installed apps, carrier info, phone numbers, and call/message logs, much of which goes beyond core functionality of individual services.

"We provide personal information to our affiliates and other trusted businesses or persons to process it for us, based on our instructions and in compliance with our Privacy Policy and any other appropriate confidentiality and security measures. We also allow specific partners to collect information from your browser or device for advertising and measurement purposes using their own cookies or similar technologies."

Google shares personal information with affiliates and service providers, and allows advertising partners to collect data directly from user devices via cookies and similar tracking technologies.

"We keep some data until you delete your Google Account, such as information about how often you use our services. And some data we retain for longer periods of time when necessary for legitimate business or legal purposes, such as security, fraud and abuse prevention, or financial record-keeping. When you delete data, we follow a deletion process to make sure that your data is safely and completely removed from our servers or retained only in anonymized form. Because of this, there may be delays between when you delete something and when copies are deleted from our active and backup systems."

Some data is retained indefinitely until account deletion, other data is kept even longer for vague 'legitimate business purposes,' and actual deletion from backup systems is delayed with no specific timeline.

"We change this Privacy Policy from time to time. We will not reduce your rights under this Privacy Policy without your explicit consent. We always indicate the date the last changes were published and we offer access to archived versions for your review. If changes are significant, we'll provide a more prominent notice (including, for certain services, email notification of Privacy Policy changes)."

While Google promises not to reduce rights without consent, non-rights-reducing changes can be made unilaterally with only after-the-fact notice, and continued use constitutes acceptance.
