- If you suspect unauthorized access to your account, please contact us right away.
3. Content & Intellectual Property
- All rights in the platform design, code, pet artwork, and FSRS memory engine belong to Kernel Tech.
- Under Taiwan’s Copyright Act Article 9, Paragraph 1, Item 5, exam questions and substitute questions for law-regulated examinations such as the University Entrance Exam, Subject Achievement Test, and Joint Entrance Exam are not protected by copyright and may be freely used or reproduced. Kernel’s use of past exam questions follows that rule. However, official explanatory answers may still be protected if they contain original expression.
- You keep ownership of your social posts and profile data and grant Kernel permission to display those materials to your selected friends within the app.
4. Disclaimers
- Learning outcomes disclaimer: Kernel is a vocabulary study support tool. While we strive to provide the best learning algorithm, we do not guarantee that using Kernel will guarantee specific exam scores or outcomes.
- The service is provided on an "as is" basis. We do not warrant that the service will be uninterrupted or free from errors. We are not liable for indirect, incidental, or consequential damages.
Part 2: Privacy Policy
This section explains what data we collect while you use our website and iOS app, and how we use that data.
1. Information We Collect
Information collected via our website:
- Waitlist information: Email address provided when joining the waitlist.
- Site analytics: Page performance metrics (Core Web Vitals), page views, referrers, and browser/OS information collected through Vercel Analytics. (No cookies and no personal identification.)
- Local preference: Language preference stored in browser Local Storage (data never leaves your device).
- Font loading: Standard HTTP requests sent to Google when loading web fonts.
Information collected in the iOS app:
- Account information: Display name, avatar URL, and email obtained via Google Sign-In (OAuth 2.0). Sign-in is optional, and you may use Kernel without an account.
- Learning data: Practice logs, correct/incorrect answers, time per question, spaced repetition status (FSRS parameters), review history, and daily activity.
- Pet and game data: XP, study streak, coin balance, pet happiness/hunger levels, pet type, color theme, pet name, unlocked outfits, and coin transaction history.
- Social data: Friend links, friend codes, online/learning/offline status, and social feed activity.
- Preferences: Exam type, target exam date, daily vocabulary target, grade level, difficulty settings, and daily review limit.
- Device data: APNs token and platform details used only for push notifications.
- Analytics events: Login and app-open events collected through PostHog and tied to an anonymous ID.
- On-device storage: Pet status, learning progress, vocabulary cache, quiz state, and activity dates are stored in your phone’s UserDefaults for offline use and widget reading.
Information we do not collect:
We do not access your camera, microphone, GPS location, contacts, health data, or photos.
2. How We Use Your Information
- Operate and improve core Kernel features.
- Schedule vocabulary reviews based on your memory state (FSRS parameters).
- Support social features so you can add friends and check learning status.
- Send study reminders and social activity push notifications.
- Process the waitlist and send launch notifications.
- Analyze app usage patterns to continuously optimize the experience.
- Prevent abuse and unauthorized access.
3. Third Parties
We use trusted service providers to operate Kernel:
- Supabase: Our database, storing account data, learning progress, friends, and pets.
- Google Sign-In: Handles authentication flow with OAuth tokens.
- PostHog: Product analytics for anonymous events such as login and app opens.
- Apple Push Notification Service (APNS): Sends push notifications to your device.
- Vercel Analytics (website only): Tracks site performance metrics with no cookies and no personal IDs.
- Web3Forms (website only): Handles email submissions for the waitlist.
- Google Fonts (website only): Provides web font files.
4. Storage & Security
Your data is stored in Supabase, where each table uses Row Level Security (RLS) so you can only access your own data. XP, coins, and streaks are also validated on the server side and cannot be tampered with from the app client. All data transfer is encrypted over HTTPS.
5. Retention & Deletion
- Retention period: Account and learning records are retained while your account exists, as the spaced repetition engine requires complete history to function correctly. Waitlist emails are kept until launch or until you request removal.
- Deleting your data: You can delete your account any time from Settings inside the app or contact us via Section 10. Once an account is deleted, your personal data is permanently removed from our servers.
6. Children's Privacy
Kernel is designed primarily for high school students (approximately 15–18 years old). We do not knowingly collect personal data from children under 13, or under 16 in the European Economic Area. If you are below these thresholds, you must use Kernel with parental or guardian consent. If we discover data from underage users was collected, we will remove it promptly. Please let us know if this applies to you.

Depending on your location (including Taiwan's Personal Data Protection Act and the EU GDPR), you have the following rights:
- Request access to personal data we hold about you.
- Request correction of inaccurate or incomplete data.
- Request deletion of your data.
- Restrict or object to our data processing.

To exercise these rights, contact us using the details in Section 10.
8. International Transfers

9. Policy Changes
