The data is already in Grindr’s systems, this means it is ALSO at Localytics (and others). This is not as safe as if it was only in Grindr’s own systems.
This is not really true. These companies entire model is handling data and they charge their partners for it. It is not a free product. As such, going off and selling the data is not really going to happen.
I said if any of these companies get acquired, the acquiring party can do whatever the hell they want with that data, previous privacy policy be-damned. This has already happened. A lot.
It really depends on how you as an entity who is supplying data to analytics firm have negotiated your contract with the analytics firm. Just saying an acquisition will completely negate all contracts before is incorrect.
Also, these agreements are between 2 companies (the company providing the data and the analytics firm which will show analytics on that data). There is no privacy policy per se in this case. It is all about contract negotiation on the rights you give to the analytics firm on how to share the data and what happens if they get acquired.
Fair point. My point is that Grindr's system are likely more vulnerable than Localytics and thus that is where the soft point exists if you are a hacker and are trying to get the data.
