Trisven Networks

About this app

★ 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.

Ratings and reviews

There's no reason why this Note application doesn't have a 4.5 or higher Google score. I've checked it out and the UI, Settings, backups, restore, color scheme, and special functions, etc. are great. Ty developers and staff. I'll come back and re-rate if there's any objections, but I suspect I will not find any.

App will not allow me to create a backup either automatically or manually. The issue does not appear related to battery, power saving, or data settings. I believe it is because Android 11 (or possibly it's Oxygen 11) only allows me to grant access to media storage. There is no option to grant full storage access to this app. UPDATE: 12/25 Manual update working but I cannot designate the destinaion fokder and have to manually move it from Downloads. Auto updates does not seem to be working..

If you want a simple notes app with encryption and local (encrypted) backup without any "online sync" bullsh!t then this app is for you. Personally I like it a lot as it is free, still I won't mind paying for additional features like text formatting in notes. For brevity, features include both password and biometric login, auto logout, dark-light-dim modes, import encrypted backup files from storage (if moving to another device, for example), note card colors and sorting and notes search.
