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.

I work in IT and I love this app and use it almost daily at work. It's a good little and secure note taking app. You either need to enter the passphrase or use biometrics to unlock access to your notes. Has a bunch of color schemes to choose from for what color your "notepaper" is. Supports protected backup and restore I back mine up to both Dropbox and Google drive.

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.

Is there any "undo"? You know, sometimes when you move your cursor to a certain position (e.g. to left most edge of the screen), it inadvertently selects a range of text below it & before you know it, you already pressed the paste button. An undo feature can help so much. Also, there is no search button inside notes!! Some search highlighting would have helped so much. Other than this, the functionality of this notes is just what I wanted. Simple & straight forward.
