We do not collect any data you create when using TaluCrypt. Why? Because we don’t even have a server to store and collect your data. It’s the primary goal of having a desktop base application: making you the owner of your data and preserving your anonymity. The data you generate are stored locally in a database file that you can access in the setting page of the app; you are the only responsible of this file and we cannot retrieve it.
The unique data we get are logs about app crashes, that’s all the data we collect, those data only contain information about crashes, and nothing related to your personal data.
