> We just all seem to assume that we can trust those entities to not misuse the data I don't need to trust that entities will not misuse my data; I have legal documents on my websites that set out how entities may use the data that they download from my sites. The terms apply to my users and to any intermediary technology providers. For the Silk browser, I don't need a data sharing agreement with Amazon because my terms say that service providers like Amazon may not copy and store data from my website for their own purposes. Amazon Silk can access my site only for the purpose of helping the end user visit my site. I expressly exclude data sharing from my relationship with service providers and users. This is a standard part of website terms and conditions; here's an example from Facebook's terms of service: > You may not access or collect data from our Products using automated means (without our prior permission) or attempt to access data you do not have permission to access. And from their platform policy: > Data Collection and Use: If you are a Tech Provider for an entity, comply with the following: > a. Only use an entity's data on behalf of the entity (i.e., only to provide services to that entity and not for your own business purposes or another entity's purposes). Data sharing agreements are only necessary when another entity (i.e. Amazon the company) wants to store and use data separate from, and in addition to, the service they provide to end users. The existence of a "data sharing agreement" is proof that device manufacturers were collecting and storing user data, not just facilitating user access to Facebook. That's what "data sharing agreement" means. Further proof is that Facebook explicitly said that some companies collected and stored FB user data.
