Can Wi-Fi Routers Track Your Browsing? Here's What I Learned After Reading 30,000 Words of Privacy Policies
Briefly

Privacy policies for routers can be extensive and complicated, often lacking clarity about data collection practices. A thorough examination of such policies reveals a tendency towards vague language, leaving users uncertain about what data is collected and how it is used. Experts, such as Bennett Cyphers from the Electronic Frontier Foundation, emphasize that while privacy policies may assure users that negative outcomes are unlikely, they offer little insight into actual data handling. This complex landscape makes informed choices about router privacy challenging for the average user.
All a privacy policy can really do is tell you with some confidence that something bad is not going to happen, but it won't tell you if something bad is going to happen.
Often, what you'll see is language that says, 'we collect X, Y and Z data, and we might share it with our business partners, and we may share it for any of these seven different reasons', and all of them are very vague.
