Phone Cleaner & Booster

"With business partners: We may share Your information with Our business partners to offer You certain products, services or promotions. With Affiliates: We may share Your information with Our affiliates, in which case we will require those affiliates to honor this Privacy Policy. Affiliates include Our parent company and any other subsidiaries, joint venture partners or other companies that We control or that are under common control with Us."

The policy grants broad permission to share user data with undefined "business partners" and a wide network of affiliates, joint ventures, and subsidiaries without specifying who they are or limiting the scope of sharing.

"The Company will retain Your Personal Data only for as long as is necessary for the purposes set out in this Privacy Policy. We will retain and use Your Personal Data to the extent necessary to comply with our legal obligations, resolve disputes, and enforce our legal agreements and policies. The Company will also retain Usage Data for internal analysis purposes. Usage Data is generally retained for a shorter period of time, except when this data is used to strengthen the security or to improve the functionality of Our Service, or We are legally obligated to retain this data for longer periods."

No specific retention timelines are given. Multiple broad exceptions (legal obligations, dispute resolution, security, functionality improvement) allow indefinite retention of both personal and usage data.

"We may update Our Privacy Policy from time to time. We will notify You of any changes by posting the new Privacy Policy on this page. You are advised to review this Privacy Policy periodically for any changes. Changes to this Privacy Policy are effective when they are posted on this page."

Changes take effect immediately when posted. While they mention email/notice, continued use constitutes acceptance and there is no mechanism for users to reject changes other than stopping use of the service.

"When You access the Service by or through a mobile device, We may collect certain information automatically, including, but not limited to, the type of mobile device You use, Your mobile device's unique ID, the IP address of Your mobile device, Your mobile operating system, the type of mobile Internet browser You use, unique device identifiers and other diagnostic data."

For a phone cleaner/booster app, collecting unique device IDs, IP addresses, and open-ended 'other diagnostic data' goes beyond what's needed for core functionality. The 'not limited to' language leaves the door open for additional undisclosed data collection.

"Usage Data may include information such as Your Device's Internet Protocol address (e.g. IP address), browser type, browser version, the pages of our Service that You visit, the time and date of Your visit, the time spent on those pages, unique device identifiers and other diagnostic data."

Collection of unique device identifiers and IP addresses, combined with sharing data with business partners and affiliates, enables tracking users across different services and building cross-service profiles.

"You have the right to delete or request that We assist in deleting the Personal Data that We have collected about You. Our Service may give You the ability to delete certain information about You from within the Service. You may also contact Us to request access to, correct, or delete any personal information that You have provided to Us. Please note, however, that We may need to retain certain information when we have a legal obligation or lawful basis to do so."

Deletion is not guaranteed — the policy says the service 'may' give you the ability to delete only 'certain' information, and broadly reserves the right to retain data under vague 'lawful basis' exceptions.
