Save to use after poweroff, or save for actual runtime?

Then you need solve 3 steps in your code.

learn and implement EEPROM emulation techniques and software for STM32 Microcontrollers - Application note
before poweroff store text to eeprom space
after poweron load back in screen or main setup stage

Maybe you dont need emulation , when your MCU have internal EEPROM or you use an external...
