留信app

Write an important letter in advance, encrypt it locally, and keep it ready for the people who matter.

Liuxin helps you prepare important personal notes in advance.

You can write a letter for family, friends, or trusted contacts, add recipient emails, and set a decryption password. Letter content is encrypted on the device before being saved to the server. The decryption password is not uploaded or stored on the server. When your configured trigger conditions are met in the future, Liuxin can enter a confirmation and delivery flow so important information has a better chance of reaching the right people.

Useful for:

• Important instructions for family
• Account or document clues
• Words you want to prepare for special situations
• Personal arrangements you want to organize ahead of time

Liuxin is not a will, legal document, medical service, emergency rescue service, financial service, or estate execution service. It is a secure preparation and reminder tool, not a replacement for professional legal documents or offline arrangements.
