Ant Safety Notes

✅Local encrypted note-taking software that keeps sensitive records on your computer

Yi Security Notes is a Windows native encrypted note-taking software for IT O&M personnel, developers, freelancers, small team leaders, and users who value personal privacy.

It is suitable for saving technical documents, server configuration instructions, work records, account profiles, project notes, customer information and personal diaries that you don't want to upload to the cloud.

Different from note-taking software that relies on cloud synchronization, Yi Security Notes saves the text, attachments and pictures of notes on the machine, and does not actively upload the content of notes, helping users reduce the risk of sensitive information being exposed to third-party cloud platforms.

✅Local encryption, sensitive content is not saved in plaintext

Sensitive fields such as note title, label, account information, text and historical version are encrypted by AES-256, and key derivation and HMAC integrity verification are performed by PBKDF2-HMAC-SHA256.

Body pictures and attachments are also saved separately and encrypted. Even if the database or attachment file is copied directly, the contents of it cannot be read properly without the correct master password.

✅Two types of emergency data destruction

Data destruction protection can be enabled when a device may be lost, inspected, or brute-force:

-Set a separate destroy password and clear the local business data after entering it
-Customize the number of password errors, automatically destroy notes after reaching the upper limit
-Support silent destruction, no confirmation or completion prompt displayed
-You can choose whether to delete local backups at the same time when destroying
-Keep lock screen password, destruction password and security settings after destruction

The scope of destruction includes notes, historical versions, custom classifications, search records, attachments, and body images, and will clean up old data in database logs and application memory.

✅Not only safe, but also smooth recording

The software provides complete daily note-taking and data management functions:

-Rich text editing, table editing and Excel table pasting
-Text pictures, attachments and image sizing
-Classification of technical documents, handy notes, password safes, etc
-Customize categories, tags, searches, and recent views
-Recycle Bin, Historical Version and Version Recovery
-Password generator and secure clipboard
-Multilingual interface switching

Whether it's collating technical data, keeping project records, or writing a personal privacy diary, it can be done in a local encrypted environment.

✅Full local backup

Immediate backup and scheduled backup are supported. A backup package can contain:

-Notes database
-Historical version
-Text Picture
-Upload attachments
Segment and related business data

The backup files can be saved to a mobile hard disk, USB flash drive or a location chosen by the user, and it supports complete recovery to reduce the risk of data loss caused by accidental deletion or computer failure.

The software will not automatically upload the backup to the cloud, and the data storage location is determined by the user.

✅Further security protection

In addition to data encryption, it also provides:

-Idle automatic lock
-Password error limit
-Anti-screen capture/screen recording protection
-Timed clearing of the clipboard
-Separation of lock screen password and destruction password
-Offline Authorization Verification
-Memory cache cleanup after data destruction

✅Which users are suitable

Ant Safety Notes are especially suitable for:

-IT O&M personnel who keep server configuration and troubleshooting records
-Developers who organize code descriptions and technical documentation
-Freelancer who keeps project and client data
-Small team leader who manages internal work records
-Users who keep personal diaries, account profiles and private information
-People who are reluctant to hand over sensitive content to cloud note-taking platforms

If you need multiplayer online collaboration, mobile and computer automatic synchronization, it is currently not suitable; If you value more local control, offline use, content encryption and emergency destruction capabilities, Yi Security Notes will be more in line with your needs.

Windows 64-bit version is currently available. The software needs to be connected to the authorization server when it is activated, but the note body, attachments, or picture content will not be uploaded.
