Indie Developer
Building small software for a better digital life.
让数字生活，好用如诗，好看如画
01 — About
Hi, I’m Hongyu Guo — an indie developer. I design and build small software that makes digital life safer, calmer, and a little more beautiful: a password manager you can trust, wallpapers that make your Mac feel alive.
Right now I’m focused on SafeVault and MaiKer, both designed, built, and shipped by myself across five platforms.

Close the lid at night — your passwords rest in the cloud as ciphertext. Built on the AES-256-GCM standard with authenticated encryption and PBKDF2 key derivation, plaintext never leaves your device; sync transmits ciphertext only, so a breached server can recover not a single password. Now listed on the iOS App Store, Mac App Store, Google Play, and Microsoft Store — download it on iOS, macOS, Android, and Windows.
Recently added — koi pond, shallow shoals, and deep sea: three real-time 3D interactive wallpapers where fish follow your cursor and a click sends ripples across the water. Plus a curated set of live wallpapers, ten ambient effects like falling petals and drifting fireflies, stardust and butterflies that bloom under your mouse, and a clock pulsing to your music. Light on CPU, quiet while you work.
