Introduction
This Privacy Policy explains what LeitnerPlus collects and how that information is used for an MVP learning-card app. It should be reviewed and finalized before a public or paid launch.
Information we collect
We collect information needed to operate the app, including account information, learning content, uploaded files, review activity, settings, and basic technical information.
Account information
Authentication may use email/password or Google OAuth through Supabase Auth. We may receive your email address and basic provider metadata needed to sign you in.
Learning content and uploaded images
Cards, questions, answers, categories, tags, learning spaces, colors, and uploaded question images are stored so you can create, browse, edit, and review your material. Card images are stored in private Supabase Storage buckets and displayed with signed URLs.
Review history and usage data
LeitnerPlus stores review logs, ratings, due dates, FSRS state, difficulty, stability, repetitions, and lapses so the review system can schedule future study sessions.
Authentication providers
If Google sign-in is enabled, Google handles the OAuth sign-in step. LeitnerPlus does not require Google client secrets in frontend code.
How we use data
Data is used to provide authentication, save cards and images, organize spaces and tags, run review scheduling, show dashboard stats, maintain settings, and improve the learning workflow.
Storage and security
LeitnerPlus uses Supabase PostgreSQL, Supabase Auth, Supabase Storage, and Vercel hosting. Row Level Security is used for app tables. We do not claim end-to-end encryption or specific compliance certifications unless separately documented.
Third-party services
The app currently relies on Supabase for auth, database, and storage; Vercel for hosting; and Google OAuth if sign-in with Google is enabled.
Cookies/local storage
Auth sessions use cookies managed through Supabase SSR helpers. Theme preferences may use local storage through next-themes. Some profile preferences may also be stored in the profile settings table if installed.
Data retention
Data is generally retained while your account exists or while needed to provide the app. Deletion and export workflows should be finalized before broad public launch.
User choices and deletion requests
You can edit or delete cards and images inside the app. For account-level deletion requests or privacy questions, contact the placeholder support address below until a final process is defined.
International users
The services used by LeitnerPlus may process data in different regions. Do not use the app if your local laws or organization rules prohibit this processing.
Changes to this policy
When this Privacy Policy materially changes, LeitnerPlus may require acceptance of a new legal version before continued use of protected app features.
