I'm currently using the pstorage functions to be able to store permenant data when turning off the power, it works good with me while writing or reading but when I turn off the power, the data is erased from the memory, I think it may be it's a volatile memory, but on its documentation it's said that it write data to flash memory and the flash memory is a non-volatile memory.
thanks in advance

//APP_ERROR_CHECK(err_code);
