Is ActivityWatch trustworthy?

judging by my routine, I think I desperately need a habit correction application. But we all know this granular level of telemetry could be the most privacy invaisive thing we can think of. On researching about ActivityWatch on popular Linux youtubers/ privacy, and linux subreddits, I didn’t find any direct assault on this service. Would love your advice. If there are alternative service providers for the same with better image/ more data on them do let me know.
