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. We may share Your information with Our business partners to offer You certain products, services or promotions."

The policy grants broad permission to share personal data with service providers, affiliates, joint venture partners, and business partners, with vague purposes like offering 'certain products, services or promotions.'

"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."

"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. Changes to this Privacy Policy are effective when they are posted on this page."

While they mention email notification, changes take effect immediately upon posting regardless of whether users have seen or agreed to them.
