BJJ RollCall (“we”, “our”, or “us”) respects your privacy and is committed to protecting your personal information. This Privacy Policy explains how we collect, use, store, and disclose information when you use the BJJ RollCall mobile application and related services (the “App”).
1. Your BJJ RollCall Account
A BJJ RollCall account lets you keep a persistent training notebook, sync notes across the mobile app and web, and unlock profile-driven features like gym management, timetable editing, and sharing highlights with teammates.
BJJ RollCall is built on Django, so the same authentication stack trusted by thousands of production sites (like Youtube, Spotify, NextDoor, EventBrite) protects your data. If you have questions about account security or would like a copy of your data, please reach out to out Contact Us email address and we’ll provide the requested details.
2. Your BJJ RollCall Account Password security
Passwords are never stored in plain text. Django’s built-in auth framework hashes every password using PBKDF2 with SHA-256 and a per-user salt before it ever reaches the database. That means even if someone obtained a copy of the database, they would still need to crack the hashed values to view a password.
Any time you update profile data or request a password reset, those actions travel over HTTPS to our Django application servers where the same encryption and hashing pipeline applies.
