Flashcards and Decks

Questions, answers, decks, review progress, and deck language settings are stored on your device. If iCloud is enabled for the app, this data may sync through your Apple iCloud account.

Account and Sign in with Apple

You can use SmartCards Study without connecting a personal sign-in. The app creates a technical Supabase user identifier to provide credits and server features. If you connect Sign in with Apple, Supabase processes the Apple identity token and the email address Apple provides, which may be an Apple private relay address. We use this information only for authentication, account recovery, synchronization, purchases, and community features.

Profile and Community

If you use the community features, we process your account identifier, chosen display name, public alias, biography, profile image, visibility setting, shared learning statistics, learning-partner relationships, invitations, shared study sessions, and presence status. Depending on the visibility you choose, profile information may be visible to you only, to confirmed learning partners, or to signed-in community members.

Profile images are stored in a protected Supabase storage bucket. Access is limited according to your profile visibility. Community members can block other users and confidentially report inappropriate profiles, harassment, impersonation, or spam. Reports are retained while they are reviewed and for as long as reasonably necessary to prevent abuse and document moderation decisions.

Learning Progress

To synchronize progress and provide streaks, XP, Gems, milestones, daily goals, statistics, and shared study rewards, the app sends learning events and aggregated activity data to Supabase. This can include review outcomes, learning-area and deck names, study duration, timestamps, time zone, and reward progress. Your flashcard questions and answers remain on your device and in your private iCloud container unless you intentionally use an AI feature.

AI Features

AI features are optional. Before the app sends any study text to an AI service for the first time, the app asks for your permission in the app.

If you choose to use AI-generated cards, photo or document analysis, the app sends the topic, selected images or documents, extracted text, target deck name, language settings, requested card count, and App Store purchase proof to our Supabase backend. The content needed for the request is then sent to OpenAI to generate flashcards.

If you choose an AI answer helper, the app sends the selected question, answer, language setting, selected helper action, and App Store purchase proof to our Supabase backend. The study text is then sent to OpenAI to generate the requested explanation, example, memory aid, mini quiz, child-friendly explanation, or exam-style answer.

When Premium Audio is requested, the required study text and language are sent through our backend to OpenAI. Generated audio files and technical metadata may be stored in Supabase so that the same audio can be played again without generating and charging it a second time. Stored audio is subject to automated retention and cleanup rules.

Do not enter sensitive personal information into AI prompts, flashcards, questions, or answers.

Subscriptions and Purchase Verification

AI features require an optional monthly subscription. The app uses Apple StoreKit and sends purchase verification information to our backend so that subscriptions and consumable credit purchases can be checked with Apple. We store account-linked credit balances and a transaction identifier to prevent the same purchase from being credited more than once. Payment details such as card numbers are handled by Apple and are not available to us.

How We Use Data

We use app data only to provide app functionality: authentication, profile and community features, progress and reward synchronization, optional AI study content and Premium Audio, purchase verification and credits, abuse prevention, and support.

Support Requests

If you use the in-app feedback form or contact support by email, we receive the information you choose to provide, such as your email address, message, screenshots, app version, screen context, device model, and iOS version. This information is used only to answer the request and diagnose the reported issue.

Data Sharing

We use service providers only to operate the app: Apple for Sign in with Apple, App Store purchases, and iCloud sync; Supabase for authentication, database, storage, and backend processing; OpenAI for requested AI-generated study content and Premium Audio; and GitHub for internal processing of submitted support reports. These providers process data under their respective data-protection terms.

Retention and Deletion

Account, profile, community, progress, purchase-credit, and moderation data is retained while your account is active or as needed to provide the feature, prevent abuse, meet legal obligations, and resolve disputes. Temporary AI inputs are processed for the requested feature. Generated Premium Audio may be retained for reuse and cleaned up automatically when it is stale or no longer referenced.

You can delete your SmartCards Study account from Settings > Account & Sync. This permanently removes your Supabase account, profile image, community relationships, server-side learning progress, and AI credit balance. Local flashcards and data in your private iCloud container are separate and remain under your control; you can delete them in the app or through your Apple account. Deleting the SmartCards Study account does not automatically cancel an Apple subscription.

Your Choices and Rights

You can keep your profile private, disable sharing of statistics, remove or block learning partners, report community profiles, avoid optional AI and feedback features, and delete your account. For access, correction, deletion, restriction, or other privacy requests, contact support@loup-digital.com.

Tracking

The app does not use third-party advertising tracking and does not track you across apps or websites owned by other companies.
