"We may ask you at login if you provide us with the access to your Contacts on your device so that we can find friends for you within Linky community... we may automatically collect information about your language, gender, clicks and actions... device data (e.g., IMEI and other device identifiers), country/region, device model, screen resolution, geographic location, anonymous user identifier, etc."
Linky requests access to device contacts and collects extensive device-level data including IMEI and other device identifiers, screen resolution, and operating system information, much of which goes beyond core app functionality.
