QuizLok LLC ("we", "our", or "us") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, and safeguard your information when you use the QuizLok mobile application.
1. Information We Collect
Account Information: When you create an account, we collect your email address and authentication credentials, and your date of birth — collected once at sign-up to verify you meet our minimum age requirement and to record your agreement to our Terms. If you sign in with Apple or Google, we receive limited profile information from those services.
Usage Data: We collect quiz completion data, scores, topic selections, and study progress to provide personalized learning experiences and track performance.
Device Information: We collect device push notification tokens to send you reminders and notifications. We do not collect device identifiers for advertising purposes.
Subscription Information: Payment processing is handled entirely by Apple through the App Store. We do not collect or store credit card numbers or payment details. We receive subscription status information through RevenueCat to manage your access.
2. How We Use Your Information
To provide and maintain the QuizLok service
To generate personalized AI-powered quizzes based on your selected topics
To track your learning progress and display performance statistics
To manage your subscription and free trial status
To send push notifications (streak reminders, quiz completion alerts) if you opt in
To manage app restrictions through the Screen Time API when configured by a parent or user
3. Third-Party Services
QuizLok uses the following third-party services. For all AI providers below, we send only topic names and (where needed) prior question texts to avoid repeats — we do not send your email, account ID, or any other personal information to any AI provider.
Supabase: Cloud database and authentication. Your account data and quiz history are stored securely on Supabase servers. Supabase Privacy Policy
RevenueCat: Subscription management. Processes subscription status and entitlements. RevenueCat Privacy Policy
Google Gemini: AI quiz generation (recall-tier topics). Topic names and prior question texts are sent to Google's Gemini API to generate new quiz questions. Per Google's Gemini API terms for paid tiers, content sent to QuizLok's API endpoint is not used to train Google's models. Gemini API Terms
DeepSeek: AI quiz generation (reasoning-tier topics). Topic names and prior question texts are sent to DeepSeek's API to generate new quiz questions for subjects that benefit from chain-of-thought reasoning. DeepSeek's data handling is governed by their published API terms. DeepSeek Privacy Policy
OpenAI: Question deduplication via text embeddings. Question texts (without any user identifier) are sent to OpenAI's text-embedding-3-small endpoint to detect near-duplicate questions across our cache. Per OpenAI's API data usage policy, content sent to the API is not used to train OpenAI's models. OpenAI Privacy Policy
Apple Sign In / Google Sign In: Authentication providers. We receive only the information you authorize during sign-in.
Expo Push Notifications: Notification delivery service. Your device push token is used solely for delivering notifications you have opted into.
4. Children's Privacy
QuizLok may be used by children under 13 when set up and supervised by a parent or guardian using Parent mode. In Parent mode:
The parent or guardian creates and controls the account
Child profiles are created by the parent locally on the device and do not require a separate email or login
We do not knowingly collect personal information directly from children under 13
All data associated with child profiles is managed through the parent's account
Parents can review, modify, or delete their child's data at any time through the app
If you believe we have inadvertently collected personal information from a child under 13 without parental consent, please contact us immediately at support@quizlok.com and we will promptly delete the information.
5. Screen Time and Device Activity Data
When the app restriction feature is enabled, QuizLok uses Apple's Screen Time API (FamilyControls, ManagedSettings, and DeviceActivity frameworks) to manage app restrictions on the device. This data:
Is processed entirely on-device by Apple's frameworks
Is never transmitted to our servers or any third party
Is never used for advertising, analytics, or any purpose other than enforcing the restrictions you configure
Cannot be accessed by QuizLok beyond the restriction and timer functionality
6. Data Retention
We retain your account data and quiz history for as long as your account is active. If you delete your account, all associated data will be permanently removed within 30 days.
7. Data Security
We implement industry-standard security measures to protect your data, including encrypted data transmission (HTTPS/TLS), secure authentication, and row-level security policies on our database. However, no method of electronic storage is 100% secure.
8. Your Rights
You have the right to:
Access the personal data we hold about you
Request correction of inaccurate data
Request deletion of your account and associated data
Opt out of push notifications at any time through your device settings
9. Changes to This Policy
We may update this Privacy Policy from time to time. We will notify you of any material changes by posting the new policy in the app and updating the "Last updated" date.
