Privacy Policy

This policy explains what information Bible Duel (bibleduel.com) collects, why, and the choices you have. In short: we collect what's needed to run the game and save your progress, we only use analytics if you allow it, we never sell your data, and there are no ads.

Who is responsible

Bible Duel is run by Tentmaker Sweden, Sweden, who is the data controller. Contact: support@johntibell.com.

What we collect

If you play as a guest

Your progress (XP, streaks, statistics, settings) is stored only in your own browser (local storage). It is not sent to us. If you later create an account, it is moved into your account.

If you create an account

• Sign-in details: your email address and password (stored securely by Firebase Authentication — we never see your password), or your Google account's name and email if you sign in with Google.
• Profile: the display name and avatar you choose.
• Game data: scores, XP, level, rank, statistics, achievements, daily streak and a history of the games you play (which questions, your answers, the time taken).
• Duels: when you play another player, your display name, avatar and score are shown to them, and the match result is saved for both players.

Public information: your display name, avatar, rank, XP and game statistics appear on the leaderboard and can be seen by anyone. Your email address is never shown publicly.

Analytics (only with your permission)

If you click “Allow” in the cookie banner, we use Google Analytics for Firebase to understand how the game is used (for example which modes are played and where players get stuck). It collects usage events, device and browser information and approximate location, and uses cookies or similar identifiers. If you don't allow it, Google Analytics is not loaded at all. You can change your choice at any time with “Cookie settings” at the bottom of the page.

Technical data

Our hosting provider processes IP addresses and request logs to deliver the website and keep it secure.

Why we use it (legal basis)

• To provide the game, your account and your saved progress — necessary to perform our agreement with you (the Terms).
• To keep the service secure and prevent cheating and abuse — our legitimate interest.
• Analytics — your consent, which you can withdraw at any time.

Who processes the data

Bible Duel is built on Google Firebase (Firebase Authentication, Cloud Firestore, Firebase Hosting and, with consent, Google Analytics), provided by Google. Our game database is located in the United States. Google transfers data under the EU–US Data Privacy Framework and the EU Standard Contractual Clauses. We don't share your data with anyone else, and we never sell it.

How long we keep it

We keep your account and game data until you delete your account. Analytics data is kept for a limited period set in Google Analytics. Server logs are kept for a short time by our hosting provider.

Your rights

You can ask to access, correct, export or delete your personal data, and object to or restrict how we use it. You can delete your account yourself at any time under Profile → Delete account; this removes your profile, statistics and game history. Duel results may remain in your opponent's match history. For anything else, email support@johntibell.com. You also have the right to complain to your data protection authority (in Sweden: Integritetsskyddsmyndigheten, IMY).

Cookies and local storage

• Necessary: sign-in state (Firebase Authentication), your game progress as a guest, sound settings, recently seen questions and your cookie choice — stored in your browser so the game works.
• Analytics: Google Analytics cookies — only if you click “Allow”.

Children

Bible Duel is family-friendly and can be enjoyed by all ages. Children under 13 should only create an account with a parent's or guardian's permission. If you believe a child has given us personal data without permission, contact us and we will delete it.

Changes

If we change this policy, we will update the date at the top. Significant changes will be announced in the game.
