Our applications do not collect any user information (personal or not).
All files and data you process using our applications are stored exclusively on your device(s) or in the cloud services you choose to use with your device(s) and no files or data are ever sent to our servers or to any third-party servers on our behalf.
If you are using any of our games with Game Center support and are logged in to your Game Center account on your device(s), information about game progress and high scores may be transferred between your device(s) and Apple’s servers. All personal information obtained from Game Center (your nickname and Game Center ID) is used exclusively for displaying and score-keeping and is never sent to our servers or to any third-party servers other than Apple’s.
If you have an iCloud account configured on your device(s), it may be used to keep progress synchronized between your different devices, but we’ll have no access to any other information stored there nor to any personal information or identifiers related to it.

You can access this site using a secure encrypted connection (HTTPS). However, in order to keep this site accessible to all users, non-secure (HTTP) connections are also accepted.
In accordance with standard security practices, the following information will be recorded when accessing this website: the date and time of your access, your IP address, what browser and operating system you where using and, when applicable, the referring web page (i.e., the address of the page containing the link you used to access the site). These records are normally stored for a period of up to 5 weeks unless otherwise required to investigate any issues.
If you contact us via e-mail, we will keep your e-mail and any information contained in it in order to allow us to communicate with you until any issues you reported are solved and, in some cases, for some time after that (usually no longer than two months) to allow for any follow-ups. Afterwards, your e-mail will either be deleted or stored in an anonymized format (i.e., removing with any information that might identify you or any persons mentioned in it) if it is considered relevant to solve any future issues.
In accordance with standard security practices, our servers will record the following information about your message: the date and time it was received, your e-mail address plus the name and IP address of the server delivering the email. These records are normally stored for a period of up to 5 weeks unless otherwise required to investigate any issues.
Our e-mail server accepts secured encrypted connections from most servers requiring them and will try to use secure encrypted connections when connecting to outside servers. However, to allow communication with users using non-secured servers, non-secure connections will be accepted and used as fallback.
Our servers are located in the European Union and are hosted by third-parties who use industry-standard best practices to prevent any unauthorized access to the servers’ contents. All our connections to these servers make use of secure encrypted channels.
We take privacy very seriously and do not collect any of your data except when absolutely necessary for our applications and services to work properly and give you the best possible experience.
