Simple, practical, private and sync-able that is Sorting Thoughts - a note taking app for private notes. Sorting Thoughts is a personal information and knowledge management app. It is designed to manage your thoughts such as moments of sudden inspirations, tasks, events, projects and anything else you may think of. The main aim of Sorting Thoughts is on delivering a trustworthy tool for your daily life in the knowledge-based society through security and simplicity. Furthermore, the sync service of Sorting Thoughts lets you sync all entries between multiple iOS devices and the desktop version. Privacy is a high value and for an app which collects personal notes essential. Sorting Thoughts abstains on cloud storage. All entered data stay on your device. The optional sync service used encrypted communication and a full end-to-end encryption. Only the device owner with the private key can decrypt the synced data. Additionally, the sync service collects no personal data like email addresses and the synced data will be automatically removed after a successful sync. The ensuring of privacy is a big concern for me as developer of Sorting Thoughts, because I'm a user too and enter my notes every day in Sorting Thoughts. Security feature summary: - no cloud storage - usage of Apple Data Protection - password protection (available with the Min Pack) - the optional sync service used a full end-to-end encryption with standardized technologies like RSA, AES and SSL/TLS Sorting Thoughts provides the following feature packs which are available via in-app purchasements: == 1.
