• Ranks progress from Rookie to Bronze, Silver, Gold, Platinum, and Diamond
• XP and rank data is stored on Supabase and displayed on the public leaderboard
• We reserve the right to adjust, reset, or remove XP and rank data if we detect fraudulent activity, manipulation, or violation of these Terms

If you create a social profile, the following information will be visible to other LensFit users:

• Your username and display name

Your workout details, personal measurements, and progress photos are never shared publicly and remain private at all times.

Friends System

You may send, accept, or decline friend requests from other users. You can remove friends or block users at any time from their profile page. Blocking a user prevents them from viewing your profile or sending you friend requests.
