Truecaller: Spam Call Blocker

"This information may include e.g.: geo-location; Your IP address; device ID or unique identifier; device manufacturer and type; device and hardware settings; SIM card usage; applications installed on your device; ID for advertising; ad data, operating system; web browser; operator; IMSI; connection information; screen resolution; usage statistics; default communication applications; access to device address book; device log and event information; battery levels of the device; logs, keywords and meta data of incoming and outgoing calls and messages to / from your device."

Truecaller collects an extraordinarily broad range of device data including installed apps, SIM card usage, IMSI, call/message metadata, battery levels, and address book access — far beyond what caller ID functionality requires.

"This information may include e.g.: geo-location; Your IP address; ... depending on your app settings and features used, limited real time activity data (such as driving and walking while using Family Protection)... We may use any of the information collected, as set out above, to provide You with location and interest based advertising, marketing messaging, information and services."

Truecaller collects geo-location data and real-time activity data (driving, walking), and uses location data for targeted advertising purposes.

"We transfer information to trusted vendors, service providers, and other partners who support our business and Services, such as providing technical infrastructure services, bug testing, analyzing how our Services are used, measuring the effectiveness of ads and services and facilitating payments as well as potential partners who may wish to work with us to provide other services. Truecaller may also share personal information with third party clients, agencies and networks."

Truecaller shares data with a wide range of third parties including vendors, partners, potential partners, ad networks, and agencies, with broad and loosely defined purposes.

"Truecaller may at any time with or without a separate notice change this Privacy Policy, and You are encouraged to review this Policy from time to time. In case of substantial changes, Truecaller will notify the Users by push notice or via notice in the Services. Your continued use of the Services after a notice of changes has been communicated to You or published on our Services shall constitute consent to the changed policy."

Truecaller can change the privacy policy at any time, even without separate notice, and treats continued use as consent to the new terms.

"we use cookies, web beacons, flash cookies, HTML 5 cookies, pixel tags and other web application software methods, including mobile application identifiers, to help us recognize you across the Services, learn about your interests both on and off the Services, improve your experience, increase security, measure use and effectiveness of the Services, and serve advertising."

Truecaller uses multiple tracking technologies including advertising IDs and cookies to track users across services and learn about their interests both on and off Truecaller's platform.

"You acknowledge and agree that Truecaller may keep and process personal information related to such request in order to be able to honor the request. Truecaller may on its own initiative, or at Your request, replenish, rectify or erase any incomplete, inaccurate or outdated personal information retained by Truecaller in connection with the operation of the Services."

The policy provides no specific data retention periods or deletion timelines, and even states it may keep personal information after an opt-out request to 'honor' the request.
