This is software that can protect and restore files in its own unique format. You can both protect and restore with just this one tool. It was created as a harassment-themed toy project. However, the contents are quite serious. It creates a .spy file by simply adding a bit of information to the original file. Features (quoted from GitHub README) Multi-stage encryption: A robust process combining classical Vigenère cipher (byte-level XOR) and modern AES-256-GCM. Full-width shared key: Access key generation using 16 full-width characters. Intentionally reduces convenience to create tension during input. Self-destruct function: If the specified expiration date is exceeded by even 1 second, or if the key is entered incorrectly 3 times, the file is overwritten 3 times with random data and physically destroyed. Evidence destruction: Upon successful restoration, the original encrypted file (.spy) is automatically physically destroyed, leaving no trace.

This is a free schedule coordination service that works with LINE and Discord. Simply create candidate dates and share the URL, and participants can easily respond with ○ or △. It also supports anonymous participation, so you can start coordinating schedules right away without registering as a member. The organizer can manage everything in one place: creating candidate dates filtered by day of the week, setting deadlines, setting minimum and maximum number of participants, and sharing the meeting location. Reminders to non-respondents and confirmation notifications can be automated through LINE and Discord integration. Once enough participants are gathered, a proposed date is presented, and you can proceed directly to confirming the schedule. It's ideal for people who want to finish coordinating schedules for drinking parties, meetups, club activities, and plans with friends with as little hassle as possible.
