When you create an account, we collect your email address and password (handled securely by our authentication provider, Supabase — we never see or store your raw password). If you choose "Continue with Google" instead, we receive your email address from Google to create your account, and never your Google password. When you log a submission or tap, we store what you enter: the technique, the training partner's name, belt level, and the date. If you choose to use the optional Friends feature, we also store the display name you pick and which private groups you belong to. That's the entire set of data BJJ Tracker collects. We don't track your location, contacts, device identifiers, or browsing activity, and there are no ads or third-party analytics trackers in the app.
Your data is used only to show you your own dashboard, trends, and log — the core function of the app. We don't sell it, share it with advertisers, or use it for anything beyond running the app you signed up for.
Data is stored in a Supabase-hosted Postgres database with row-level security, so your submissions are only ever readable by your own account — not by other users, and not by us in the normal course of operating the app.
The Friends feature lets you join private groups by invite code and compare weekly submission counts and streaks. Only members of a group you join can see your display name and those summary numbers (counts and streak length). Your technique log, training partners, and email address are never shared with other users. You can change your display name or leave a group at any time from the Friends page.
You can edit or delete any submission or tap at any time from within the app. If you want your entire account and all associated data permanently deleted, email us at thedorpoise@gmail.com and we'll remove it.
BJJ Tracker is not directed at children under 13, and we do not knowingly collect data from anyone under 13.
If this policy changes, we'll update the date at the top of this page. Continued use of the app after a change means you accept the update.
