MapleStory : Idle RPG

"We collect information when you use our Services, including your Internet protocol ("IP") address and other identifiers that are assigned to your device... MAC address and other device identifiers, information from your device (including information from and about your hard drive and other storage devices, central processing unit, random access memory, video card, and peripheral hardware, software and applications installed on your device)."

Nexon collects granular hardware specs (CPU, RAM, video card, hard drive info) and a list of all software installed on your device, which goes well beyond what is needed for basic game functionality.

"Consistent with your device permissions, we may collect or derive location information from your device's GPS signal, Bluetooth connections, nearby WiFi networks, and similar device information. We also may derive location from your IP address."

Nexon collects precise location data from multiple sources including GPS, Bluetooth, and nearby WiFi networks, which enables continuous and granular location tracking beyond simple IP-based geolocation.

"We disclose information to third-party partners and service providers, including payment processing and gateway companies, platform services, API services, game developers, game publishers, game console providers, customer support services providers, cloud storage and hosting providers, social media companies (who may collect information when you use the Services or when you connect the Services to your social media accounts) and analytics and advertising companies, to help us provide and improve the Services."

Nexon shares user data with a broad range of third parties including advertising companies and social media companies that may independently collect data when you use Nexon's services.

"Link the different devices that you might use to analyze your use of the Services, customize advertising, and otherwise provide and improve the Services... we and our analytics providers, advertising networks, advertising service providers, and other business partners may collect and store information about your use of our Services and emails using cookies, pixel tags, local storage, and similar technologies across websites, applications, and your different devices."

Nexon and its ad partners track users across multiple devices, websites, and applications to build unified profiles and deliver targeted advertising.

"We may make changes to this Privacy Policy, in which case we will notify you before such changes take effect by posting the updated policy through the Services or otherwise in accordance with applicable law. Any changes to this Privacy Policy will take effect after a reasonable time period as specified in the notice of such changes."

Nexon can change the privacy policy unilaterally with only a posted notice and a vaguely defined 'reasonable time period,' requiring no affirmative user consent.

"Data we collect will be retained only for so long as reasonably necessary for the purposes set out above, unless applicable law requires otherwise. Please note that information collected by third parties may not have the same security protections as information you submit to us, and we are not responsible for protecting the security of such information."

The main policy provides no specific retention periods, using only the vague standard of 'reasonably necessary,' giving Nexon effectively unlimited discretion over how long data is kept.

"The laws in your country may provide you rights to request access to, correct, restrict, port, copy, or delete your information, request that we delete your account... To exercise your rights consistent with applicable law, please contact us at the contact details provided in Section XI. (Contact Us)."

There is no self-service account or data deletion option; users must contact support via email to request deletion, and a deletion request 'may result in your inability to access the Services.'
