Privacy
The short version: we store what is needed to keep your place in a course and to run a subscription. Nothing else.
What we collect
Coursium stores your course progress, your language and appearance preferences, and — if you sign in — the email address tied to your account. Analytics events record which screens you open and which lessons you finish, so we can tell which courses work.
What we do not collect
We do not collect your contacts, your location, your photos, or the contents of anything you write outside the app. We do not sell personal data.
Who processes it
Supabase stores your account and progress. RevenueCat handles subscriptions; Apple and Google process the payment itself and we never see your card. Mixpanel and PostHog process usage analytics.
This website
This site sets no advertising or tracking cookies and runs no third-party analytics. Your light or dark mode preference is stored in your own browser and never leaves it. Our host records standard server request logs.
Your choices
You can turn analytics off in the app, and you can ask us to delete your account and everything attached to it. Deletion is permanent.
Children
Coursium is intended for adults and is not directed at children under 13. We do not knowingly collect personal data from them.
