A streak you faked is a counter measuring your pretending.

A number you keep for your own benefit only works while it reflects something real. Log a day you did not do and the counter stops describing the habit and starts describing your relationship with the app, which is not worth tracking. The odd part is that the small satisfaction still arrives, and that is how the whole system quietly becomes decoration.

Break it honestly and start again from one. Better still, decide what the smallest genuine version of the day looks like and count only that. A short true record beats a long invented one.
