Privacy policy

B Curious processes the information needed for your account, such as your email address, display name, avatar, language and preferences.

The app also records learning progress: completed lessons, answers, review cards, XP, streaks, rewards and goals. If you use social features, it also processes friend requests, messages, clubs, duels and writing you publish.

Some preferences, such as theme choice or saved highlights, may remain only in local storage on your device.

This data is used to save progress, schedule reviews, personalise your learning path, provide requested social features and protect the service.

B Curious does not sell personal data.

The free plan is paid for by ads, served by Google AdSense. Google and its partners may use cookies or similar identifiers to show ads, measure them and, if you agree, personalise them to your interests.

In the European Economic Area, the UK and Switzerland, you are asked for consent before any personalised advertising, and you can change your choice at any time from the cookie settings link. You can also manage ad personalisation at adssettings.google.com.

Advertisers never receive your progress, answers or messages. Thinker and Scholar members see no ads.

Authentication and application data are hosted using Supabase and Lovable deployment infrastructure. If you choose Google sign-in, Google participates in authentication under its own terms.

Account data is retained while the account is active or while needed for service operation and security. Direct account export and deletion controls must be added before commercial launch.

Do not publish sensitive information in messages, clubs or community writing.
