Web
Publishes to 5 app stores
- OPPO
- vivo
- Honor
- Xiaomi

Yunci Release is a web release tool for Android developers. Upload an APK and it encrypts the code, re-signs it with your own certificate and submits it to OPPO, vivo, Honor, Xiaomi and Meizu with your own store keys. There is nothing to install and no need to log in to each store’s console, and every account gets one free hardening and one free distribution a month. The interface is in Chinese only.
Who it’s for
Developers publishing Android apps to app stores in mainland China.
Features
- One-click hardening: all dex files are encrypted with AES-256-GCM and decrypted in memory at runtime
- Anti-repackaging: the decryption key is bound to your signing certificate, so a re-signed copy won’t start
- Runtime self-checks: on launch it looks for debuggers and traces of Frida or Xposed, and exits if it finds them
- Re-signs with your certificate: v1 + v2 + v3 with a fingerprint check, so published apps can still update normally
- Five stores in one submission: choose any of OPPO, vivo, Honor, Xiaomi and Meizu, and it still counts as one use
- If a store fails, resubmit to that store only at no extra count; failed hardening runs are refunded automatically
- You use your own store keys and certificate, stored encrypted and never shown again; finished packages are kept for 7 days

FAQ
How much can I use for free?
Each account gets one free hardening and one free distribution per calendar month (Beijing time), with no membership and no rollover. One distribution can cover all 5 stores.
Which packages can be hardened?
Release APKs with minSdk 29 (Android 10) or higher that no other tool has hardened. Packages that don’t qualify can still be distributed without hardening.
What counts as one use?
Hardening one APK and distributing it to any number of stores counts as one use. Hardening only or distributing only also counts as one.
Does hardening guarantee my code can’t be cracked?
No. Any hardening only raises the cost of cracking.
Can I use it for Google Play or Huawei AppGallery?
Hardening isn’t recommended for Google Play packages, as the service is aimed at Android stores in mainland China. Huawei AppGallery isn’t supported yet.
