By downloading, installing, or using VocaUp, you acknowledge that you have read, understood, and agree to be bound by these Terms of Service and Privacy Policy. If you are using the app on behalf of an organization, you represent that you have the authority to bind that organization to these terms.

3. User-Generated Content & AI Processing

3.1 Content You Upload

• You grant VocaUp a limited, non-exclusive license to process your content solely for game generation
• Your uploaded content is temporarily stored for processing and deleted after game generation
• You are solely responsible for ensuring you have rights to upload and process any content

3.2 AI-Generated Content

IMPORTANT DISCLAIMER: All game content (questions, answers, definitions, etc.) is generated by artificial intelligence. While we strive for accuracy, AI-generated content may contain errors, inaccuracies, or inappropriate material. VocaUp makes NO WARRANTY regarding the accuracy, completeness, or suitability of AI-generated content for any educational purpose.

• AI-generated games are provided "AS IS" without any guarantees
• You should verify all content before using it for educational purposes
• VocaUp is not liable for any educational or academic consequences resulting from inaccurate content

4. Credit System & Payments

4.1 Understanding Credits

4.2 Subscription Tiers

VocaUp offers multiple subscription plans:

VocaUp offers multiple subscription tiers (Free, Basic, Pro, Premium, Ultimate) with different monthly credit allowances. Current prices and credit details are shown in the app and in the Google Play / Apple App Store listings. Prices may differ by region and platform.

4.3 Credit Usage Examples

• Generating a 10-question quiz = 10 credits
• Generating a matching game with 6 pairs = 6 credits
• Generating a sorting game with 8 items = 8 credits
• If you have 5 credits but want to generate 8 questions, you'll need to watch an ad

4.4 Billing & Renewals

• Subscriptions auto-renew monthly from your subscription date (not calendar month)
• When changing subscription tiers, your remaining credits are preserved and added to your new tier's monthly allocation
• All payments are processed through Google Play Billing
• 14-day withdrawal right: EU/EEA consumers have a 14-day right of withdrawal — see Terms of Service.
• You may cancel your subscription at any time through Google Play, but no partial refunds will be issued for unused time

4.5 Device-Based Subscription Sharing

• Owner Access: The Google account that purchased the subscription can use it on any device (up to 3 devices)
• Shared Access: Any user who signs into the app on the original purchase device automatically gets access to the subscription
• Shared Credits: All users sharing the subscription use the same credit pool
• Example: User A buys Basic on Device 1. User A can use it on Device 1, 2, and 3. User B signs into Device 1 and also gets Basic access with shared credits.
• No Sharing on Other Devices: User B cannot use the subscription on Device 2 or 3 - only the owner (User A) can

Why This Model?

Google Play subscriptions are tied to a single Google account per app. This device-sharing model allows families or multiple users on a shared device (tablet, school device) to benefit from one subscription while maintaining per-user game history and statistics.

4.6 Free Tier & Advertisements

• Free tier users can watch rewarded video ads to generate games without spending credits
• Premium users with available credits can generate games without ads
• If premium users run out of credits, they can watch ads to continue generating
• Ad availability is not guaranteed - VocaUp is not responsible if ads fail to load

4.7 How Payment Processing Works

VocaUp uses Google Play Billing exclusively for all payments. We do NOT process, store, or have access to your payment card details.

Step-by-Step Payment Flow:

1. Choose Subscription: You select a subscription tier (Basic, Pro, Premium, or Ultimate) in the app
2. Google Play Dialog: The Google Play payment dialog opens within the app
3. Payment Confirmation: You confirm payment using your Google account payment method (card, PayPal, gift card, etc.)
4. Secure Processing: Google processes the payment on their secure servers - we NEVER see your payment details
5. Purchase Token: Google sends us an encrypted "purchase token" (proof of purchase)
6. Token Verification: Our backend verifies this token with Google Play servers to confirm authenticity
7. Subscription Activation: Upon successful verification, your subscription and credits are activated in our database (Supabase)
8. Sync to Device: The app syncs with our backend and updates your available credits and tier

Upgrade/Downgrade Behavior:

VocaUp offers multiple subscription tiers (Free, Basic, Pro, Premium, Ultimate) with different monthly credit allowances. Current prices and credit details are shown in the app and in the Google Play / Apple App Store listings. Prices may differ by region and platform.

Cancellation & Reactivation:

• Cancel: Your subscription remains active until the end of the current billing period
• Reactivate: You can reactivate anytime before expiry through Google Play or the app
• After Expiry: You revert to Free tier. Unused credits are lost.
