A cross-platform for file, password, information manager and an encryption tool at the same time. It can be used offline or synced with your own cloud storage.

Powered by ChaCha20-Poly1305 (https://developer.apple.com/documentation/cryptokit/chachapoly), encryption chosen by Google, 1LimX MacOS app is now on Appstore:

MacOS version 3 major changes:

1. SYNC USING YOUR GOOGLE DRIVE - 100% privacy (ensure that in all devices, the SAME MASTER KEY, MASTER PASSWORD are being used)

MacOS version 2 major changes:

1. Rich Text has arrived for creating secure, captivating and Intuitive messages, notes:
2. Templates, Categories up to 100 each used in items in the FREE version.
3. Viewing files, images of all items in Settings is now available in the FREE version.
4. Import, export data with CSV, XLS, XLSX, JSON, ...

MacOS version 1 major changes:

1. Faster encryption (see app preview).
2. Scan QR code to get 2FA code from application screenshot (see app preview).
2. Free tier up to 125MB per file attachment.
3. Preview an encrypted file directly in the app. No need to save or use external apps.
4. In Settings, click on "See master key," you can authorize to view your master key and a QR code image of it. If you have new devices to install 1LimX, simply scan the QR code with their cameras to retrieve the master key.
5. New custom data encryption tool for text, rich text and files:

The current way to encrypt and decrypt a file or text is:
1. Create an item (like an internet account item).
2. Create a new text, rich text or file field containing your chosen data.
3. Press Save. The data will be encrypted automatically.
4. Create a backup of that item to obtain the final encrypted file usable on other devices with 1LimX installed.

Now with the custom data encryption tool, text can be encrypted and decrypted right on the screen. With files, just select the file to be encrypted or decrypted and select a folder to save that encrypted or decrypted file.

You'll still need the current approach to encrypt multiple files at once.

The Master Password, Master Key
The password, key only you know used to encrypt your data all offline.

100% Security & Privacy
Your data is encrypted with industry-standard 256-bit encryption, ChaCha20-Poly1305, chosen by Google. Everything from setting up your master password, master key to storing your data happens on your device, offline, and is accessible only by you.

Gigabytes of data encryption done in seconds because everything is happening offline on your device.

Multiple Data Types
Text, rich text, file, image, date, time, 2-factor authentication,... supported.

Not just a secure file manager, information, or password manager, 1LimX has tools that help you save time:
Auto backup.
Password generator.
Custom text, rich, files encryption.
Extracting text from your phone, camera-taken image, and filling in multiple item fields at once.
Back up all your data and files to a single, sharable encrypted file for easy access on other devices with 1LimX installed there.


How does this work?
The app will generate a unique master key, combined with your master password, to encrypt your data using strong encryption chosen by Google, ChaCha20-Poly1305.

What is an 1LimX backup file? Is it encrypted?
1LimX backup files are encrypted files generated by the 1LimX app that pack all your encrypted data into a single sharable file. You can share and access your data on other computers where 1LimX is also installed using the backup file. In short, the backup files are encrypted with the same ChaCha20Poly1305 algorithm as your data within 1LimX, ensuring secure data transfer.
