Zyper is a lightweight utility for Xiaomi, POCO, and Redmi devices that prevents custom themes and fonts from automatically reverting to the system default.

By default, MIUI and HyperOS reset third-party .mtz themes and custom fonts after 30 to 60 seconds. Zyper solves this by running a reliable background service to bypass this restriction, locking your applied customizations permanently.

Features:
- Prevents third-party .mtz themes and fonts from resetting.
- Fully supports MIUI and HyperOS.
- Minimal battery consumption via an optimized background service.
- Clean, straightforward, and easy to use.
