Safe Notes - Encrypted Notepad vs Tella
Side-by-side comparison of two open source alternatives
Safe Notes - Encrypted Notepad
★ Safe Notes is an open-source project that aims to provide an encrypted, private note manager. ★ Employs rigorously tested AES-256 encryption standards to encrypt your notes. ★ Incognito Keyboard ★ Brute-force protection ★ Protection against data snooping via adb ★ Android background snapshot protection ★ Inactivity guard ★ Automated encrypted backup ★ Arctic Nord style dark and light theme ★ Customization for colorful notes ★ Seamless migration to new device. Use the backup to move your data from one device to another device. ★ Safe Notes provides ultimate security - you don't have to trust us, or any other third party because everything is done locally on your phone. ★ Contrary to the ongoing frenzy of "move everything to cloud" we believe in "localization of user data" giving you the control of your data and not some third-party cloud service provider. ★ Completely anonymous, no inbound and outbound requests. --- How it works --- ★ Safe Notes encrypt each note with a unique AES-256 symmetric key derived from your passphrase and randomly generated salt. ★ If an attacker tries to brute-force your encrypted notes it will take "Trillions Upon Trillions years" in contrast, the universe has only existed for 15 billion years. (You must use strong and long passphrase). ★ AES-256 is symmetric key encryption that is quantum-resistant, i.e. it isn't vulnerable to quantum computers. ★ Everything is stored locally on the user's device. ★ Your passphrase is never stored on the device, it gets purged as soon as you exit the app. ★ We can't decrypt your notes even if we wanted to. That gives you the ultimate security, but it also means that a lost passphrase can never be recovered. ★ Safe Notes is an open-source, not-for-profit project.
Tella
In challenging environments with limited or no internet connectivity or in the face of repression Tella makes it easier and safer to document events, whether that’s violence, human rights violations, corruption, or electoral fraud. ENCRYPTION: All of the content and data stored in Tella are encrypted. This means that unless the app is unlocked, all the data within Tella will remain inaccessible. FILE MANAGEMENT: Take photos, videos, or audio recordings directly in Tella, or import documents from your phone, and easily organize your files in folders. CAMOUFLAGE: Change the app icon and name to a seemingly harmless one, such as a calculator or a camera. QUICK DELETE: In just a few seconds, delete all the sensitive data and files stored in Tella. DATA-COLLECTION: Groups and organizations can collect data through forms and surveys, and received the data directly on their server.
