My highest streak is around 48 days but on the statistics page (1 year) it states my highest streak is over 100 days.
Because you set filter ‘year ago’. Or you joined the app later than one year and it treats time before as time without relapses. Or you didn’t donate so it shows only last 10 relapses and time before is treated as time with no relapses.
Set ‘six month ago’ and it should be correct.
