## What is TangCipher?

TangCipher is a private text encryption tool designed for personal conversations, confidential business communication, and secure information sharing.

Encrypt and decrypt messages directly on your device, then share the encrypted text through the communication channels you already trust. TangCipher helps protect the encryption step without requiring a TangCipher cloud account, online messaging service, or server-based storage.

FOR PERSONAL COMMUNICATION

Use TangCipher for private notes, personal conversations, family plans, travel details, and messages shared with a partner, family member, or friend. Create your own encryption workflow for information you prefer to keep private before sharing.

FOR BUSINESS COMMUNICATION

Prepare confidential project details, contracts, pricing information, meeting notes, client information, internal instructions, and other professional text before sharing it with a colleague, partner, or client. TangCipher helps you add an extra layer of privacy to business communication without changing the tools you already use.

CORE FEATURES

• Text Encryption and Decryption

Convert readable text into encrypted text and decrypt it using the corresponding protection method.

• Password Books

Create and manage password books for repeatable encryption and decryption. Password books remain stored locally on your device.

• Image-Based Password Books

Create a password book from a selected image. Use visual content as part of your encryption workflow without maintaining long character lists.

• QR Backup and Sharing

Create password-book backups as QR images and share them with trusted people. Recipients can import the backup into TangCipher using the transfer content provided.

• Local-First Processing

Encryption and decryption happen on your device. Your text does not need to be uploaded to a TangCipher server.

• Focused and Flexible

TangCipher does not replace your messaging apps. It helps you prepare encrypted text before sharing it through the communication methods you already use.

NO ACCOUNT REQUIRED

TangCipher can be used without creating a cloud account. Your password books and encryption tools remain under your control on your device.

FOR PEOPLE YOU TRUST

Whether you are sharing a personal message with someone close to you or confidential business information with a colleague, TangCipher helps you keep control of the encryption process and decide how information is shared.
