  • Files you choose to encrypt or decrypt
  • File metadata (e.g., filename, size, format) required for encryption/decryption operations
  • Encryption/decryption keys (passwords) provided by you
  • Temporary processing data required for encryption/decryption operations

Data Processing

Local Processing:

  • All file encryption and decryption operations are performed locally on your system without external data transmission
  • No files are uploaded to external servers during any encryption or decryption operation
  • Temporary files are created and deleted securely during processing
  • No API keys or external services are required for any operations

Data Storage

No Data Retention:

  • We do not store or retain copies of your files after encryption or decryption

Security Measures

Data Protection:

  • All file encryption and decryption is performed in a secure local environment
  • No network connections are made for file operations
  • Temporary files are handled with appropriate security measures
  • No external API calls or service dependencies
  • Encryption keys are processed locally and never transmitted

Supported Operations

The plugin supports the following file encryption and decryption operations, all performed locally:

  1. Simple Encryption (Manual Key): Encrypt PDF, ZIP, or 7Z files with a manually provided key
  2. Simple Encryption (Auto-generated Key): Encrypt PDF, ZIP, or 7Z files with an automatically generated key
  3. Pro Encryption (Manual Key): Encrypt any file type with a manually provided key and custom suffix (locked, enc, secret)
  4. Pro Encryption (Auto-generated Key): Encrypt any file type with an automatically generated key and custom suffix (locked, enc, secret)
  5. Normal Encryption (Manual Key): Encrypt any file type with a manually provided key and custom suffix (locked, enc, secret)
  6. Normal Encryption (Auto-generated Key): Encrypt any file type with an automatically generated key and custom suffix (locked, enc, secret)
  7. Simple Decryption: Decrypt PDF, ZIP, or 7Z files that were encrypted with the simple encryption method
  8. Pro Decryption: Decrypt files with suffixes locked, enc, or secret into their original formats
  9. Normal Decryption: Decrypt files with suffixes like .pdf.locked, .mp4.enc, .xlsx.secret into their original formats

All operations are executed entirely on your local machine without any external dependencies.
