Privacy
Your account
When you create an account, Stemosphere stores your email address, display name, and account identifier. Signing in with Google may also provide your profile picture. Stemosphere does not receive your Google password.
Your learning records
Your selected subjects, completed lessons, submitted answers, practice results, and saved questions are stored with your account so you can return to them later. These records are private to your account. Authorized administrators may access account records to operate the platform.
Cookies and visitor counts
Authentication cookies keep you signed in. Where visitor counting is active, a first-party random identifier is used with first-seen and last-seen timestamps and a visit count. Stemosphere does not use this identifier to fingerprint your device.
Services that operate the site
Supabase provides account authentication and database storage. Vercel hosts the website. Google processes sign-in requests when you choose Google login.
Optional features
AI tutoring and website contact submission are currently unavailable. The website does not send your learning answers to an AI provider.
