D1 Journal

D1 is a simple yet highly secure platform where you can confidently detail thoughts, plans, or any sensitive information you want accessible exclusively only to you. D1 uses powerful AES256 encryption and industry standard cryptography techniques to block access to your data from potential attackers. Your passwords and PINs are immediately hashed after you enter them and are mathematically nearly impossible to reverse engineer. Simply put: without your password, your encrypted data may as well not exist. D1 synchronizes your encrypted journal entries with a remote server so you can access them across all your devices by simply changing your User ID in D1's settings. You can also choose to enable biometric authentication, which will take advantage of either Touch ID or Face ID sensors if available on your device to lock out local attackers as an added layer of security.
