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

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.

I recently started using this app, and it has been incredibly useful and well-designed! :) However, I’d love to see support for Markdown and the ability to import/export notes from external sources like .md or .json files. I have a lot of notes that I want to migrate, but manually typing them isn’t practical. Adding this feature would make the app even more powerful! Also, I was wondering if the development has been paused, as there haven’t been updates for around 1–2 years (I might be wrong)
