I assume Chinese rules and 7.0 komi:
How did you know it was 7.0 komi?
Because that’s the only way for the result displayed (jigo) to be possible for this game. The komi should be displayed somewhere, probably in the game setup or game info screen, but we have to assume it since we only see the result displayed in the app.
It’s also how much the first-move advantage is worth on a 9x9 board under Chinese rules. So I would assume 7.0 komi even if I didn’t have to deduce it like @polar-bear said.
