We don't care about your data. We just want to make games.
We don't actively collect any personal data apart from some minimal data to track bug crashes that are collected automatically through the respected stores Lost Echo is available. (which we never look at, since they're not really useful)
We do not want or need any data from you and in areas where we can avoid gathering (directly or indirectly) any data, we do so (it's much harder than you think, or impossible, when you have to rely on 3rd party stuff).
We do use some 3rd party services that may collect information used to identify you.
On Android devices we use Google Play Services (for achievements and cloud saves).
We use Unity, the game engine. We may not care about your data, but it seems like Unity does.
To the best of our knowledge, we have disabled all of the built-in Unity Analytics and Data Collection we are able to and we don't use any of their services, but we can't guarantee that no data collection happens at all from the Unity Engine.
Turns out, making a game and having it collect nothing is close to impossible these days.
On our website, we use disqus to allow people to comment on our blog posts.
Also on our website, through our host, anonymous data are collected every time someone visits the site. Data like, browser version, operating system used, referral URL, IP address. These are available to us in anonymous form, through software like Webalyzer and are stored on our web server of our web hosting provider. This data is not passed on to third parties. We look at those occasionally to see how much traffic our site is getting.
