It has options to hide or obscure the location, which I use whenever I'm anywhere near my house, but it should be a little better about prompting users to use that.
replyStrava (a running tracking app) provides two helpful controls you can set as your default:
reply1. “Hide the start and end points of activities that start at SPECIFIC addresses.” 2. “Hide start and end no matter where they happen.”
Then it can be useful to add your home/work/routine locations.
If iNaturalist doesn’t have a setting like that, it’s a nice approach — especially if it’s included as part of initial onboarding flow — so it helps people without needing to remember to make visibility choices each time.
