Legal
There are two notices, because there are two different things going on.
The store
Buying a vploq from the online shop involves your name, a delivery address and a payment. That is covered by the store privacy policy.
The service
Using the app, the device and the vploq network is a different set of data for a different reason. That is covered by the service privacy policy.
It is in force. The current version and its effective date are stated at the top of the page itself.
The two notices do not overlap: the store one covers your order, the service one covers your account, your devices and the network. Neither replaces the other.
Reporting a security problem
If you have found a security vulnerability in the app, the device or anything we run, the vulnerability disclosure policy says how to tell us and what happens next. The same contact is published in machine-readable form at /.well-known/security.txt.
Terms of service
A separate document, not yet written. Terms and a privacy policy answer different questions and are deliberately not merged.
