I've wanted a smartwatch, but times I'd looked into smart watches, especially for activity/sleep tracking, I couldn't find a single one with a reasonable privacy policy. In the US, unless the data are self-hosted or covered by HIPAA, there's nothing binding about a privacy policy. Even if the privacy policy currently prevents the data from being sold, the policy can be changed, the company could be bought, or the company could go bankrupt with the databases sold at auction. Because HIPAA covers medical companies rather than medical data, it does nothing to prevent this. Until this loophole is closed (or a miracle happens and the US passes something akin to the GDPR), the lack of privacy prevents me from getting one. And every time I hear about the Pebble and self-hosting, I get disappointed that it no longer exists.
