My Private Note

A simple, secure way to share notes.

Frequently Asked Questions

My Private Note is a secure web application that allows you to create and share notes with optional password protection, expiration dates, and one-time view functionality. It also includes a password generator for creating secure passwords.

To create a note:
  1. Type your note in the text area.
  2. Choose an expiration date (optional).
  3. Set a password (optional).
  4. Click "Save Note" to generate a shareable link.

No, once a note is saved, it cannot be edited. You can create a new note with the updated content.

If you set a password, anyone who accesses the note must enter the correct password to view it. The note is encrypted on the client side, ensuring that only someone with the password can decrypt and read it. For more details, see How does encryption work for notes with passwords?.

If you enable the "Read Once" option, the note will be automatically deleted from the server after it is viewed once. Make sure to save the note if you want to keep a copy.

Notes are stored based on the expiration date you choose (1 day, 3 days, 1 week, or 4 weeks). If no expiration date is set, the note will remain 4 weeks until deleted.

Yes, your data is secure. Notes with passwords are encrypted on the client side using a strong algorithm (AES-GCM), and only the encrypted data is stored on the server. Passwords are also hashed before being stored. However, always use strong passwords and share them securely.

Yes, My Private Note does not require an account. Simply create and share notes anonymously.

For notes with passwords, My Private Note uses client-side encryption to ensure maximum security:
  • Encryption on the Client Side: When you create a note with a password, the note is encrypted in your browser before it is sent to the server. This means the server never sees the unencrypted content of your note.
  • Secure Storage: Only the encrypted version of the note is stored on the server. The encryption process uses a strong algorithm (AES-GCM) and a unique key derived from your password.
  • Decryption on the Client Side: When someone accesses the note, the encrypted data is sent back to their browser, where it is decrypted using the password you provided. The server never has access to the decrypted content.
This ensures that your note remains secure and private, even if the server is compromised.

Your data is automatically deleted based on the expiration date you choose (1 day, 3 days, 1 week, or 4 weeks). If you enable the "Read Once" option, the note is deleted immediately after being viewed. Once deleted, the data is permanently removed from our servers and cannot be recovered.

The password generator allows you to create secure passwords with customizable settings:
  • Length: Choose the length of the password (default is 12 characters).
  • Character Types: Include uppercase letters, lowercase letters, numbers, and special characters.
  • Shareable Link: Optionally generate a shareable link that creates a self-deleting webpage to share the password securely.
The generated password is displayed on the page, and if you choose to share it, the password is stored securely and automatically deleted after one hour or once viewed.

When you generate a password and choose to share it, a unique link is created that leads to a self-deleting webpage:
  • One-Time Access: The password can only be viewed once. After it is accessed, the webpage is deleted.
  • Automatic Deletion: If the password is not accessed within one hour, it is automatically deleted from the server.
  • Security: The password is stored securely and encrypted during transmission.
This ensures that your shared passwords are only accessible for a limited time and cannot be reused.
