You represent that you have all necessary rights to submit any content and that your content does not violate any third-party rights or applicable laws.

7. Subscriptions and Payments

Some features of InfinLume are offered as paid, auto-renewing subscriptions purchased through Apple App Store or Google Play Store billing. The current paid subscription tier offered in the submitted mobile app is InfinLume Plus.

InfinLume Plus may unlock features such as Knowledge Hive access for every CEFR level, unlimited daily practice quizzes, full audio for supported library books, and other Plus features described in the app before purchase. Feature availability may vary by platform, region, app version, language, content catalog, or technical availability.

• Plus may be offered in monthly or annual subscription periods. The displayed subscription title, price, billing period, and any trial or introductory terms are shown before purchase confirmation.
• Payment is charged to your Apple ID or Google Play account at confirmation of purchase.
• Subscriptions automatically renew unless canceled at least 24 hours before the end of the current billing period.
• Your account may be charged for renewal within 24 hours before the current period ends.
• You can manage or cancel your subscription in your device store settings:
  • iOS: Settings > Apple ID > Subscriptions, or apps.apple.com/account/subscriptions
  • Android: Google Play > Payments & subscriptions > Subscriptions, or play.google.com/store/account/subscriptions
• Deleting your InfinLume account does not automatically cancel an active store subscription; cancellation must be completed in the store account where you subscribed.
• A Restore Purchases flow is available in the app to recover eligible entitlements tied to the same store account.
• We may use subscription infrastructure providers such as RevenueCat to validate purchases, restore purchases, and keep your Plus entitlement in sync with your InfinLume account.
• We do not receive or store your full payment card number; payment details are handled by the applicable app store and its payment processors.
• Prices may vary by region and currency, and may include taxes where applicable.
• If a price changes, the applicable app store will notify you and, where required, obtain your consent before new pricing takes effect.
• Refunds and billing disputes are handled by Apple App Store or Google Play according to their policies.
• Nothing in these Terms limits any non-waivable consumer rights available under applicable law.

8. Free Trial and Introductory Offers

We may offer free trials or introductory pricing for eligible subscriptions. Eligibility is determined by Apple App Store or Google Play and may vary by account, region, and prior usage.

If a trial or introductory offer is provided and not canceled at least 24 hours before the offer period ends, the subscription converts to a paid subscription and renews automatically under Section 7.

Where permitted, offer access may be limited to one trial/introductory offer per account or per subscription offer.
