Terms of Use

Last updated: August 30, 2026

Please read these Terms of Use ("Terms", "Terms of Use") carefully before using the LinguoBook mobile application (the "Service" or "Application") operated by LinguoBook ("Company", "We", "Us", or "Our").

Your access to and use of the Service is conditioned upon Your acceptance of and compliance with these Terms. These Terms apply to all visitors, users, and others who access or use the Service.

By accessing or using the Service, You agree to be bound by these Terms. If You disagree with any part of the terms, then You may not access the Service.

1. User Accounts

When You create an account with Us, You must provide information that is accurate, complete, and current at all times. Failure to do so constitutes a breach of the Terms, which may result in immediate termination of Your account on Our Service.

You are responsible for safeguarding the credentials that You use to access the Service and for any activities or actions under Your password. You agree not to disclose Your password to any third party. You must notify Us immediately upon becoming aware of any breach of security or unauthorized use of Your account.

2. Subscriptions and In-App Purchases

Subscriptions and Billing

The Application offers subscription-based access ("Premium Subscription") that unlocks full functionality and an ad-free experience. Subscriptions are billed on a recurring and periodic basis (such as monthly or annually), depending on the subscription plan You select.

All payments and transactions are processed directly through the Google Play Store or Apple App Store. We do not directly collect or store Your financial credit card details. Subscription entitlements are validated and managed via third-party infrastructure (RevenueCat).

Auto-Renewal and Cancellation

  • Automatic Renewal: Your subscription will automatically renew at the end of each billing cycle unless You cancel it or auto-renew is turned off at least 24 hours before the end of the current period.
  • Cancellation: You may cancel Your subscription renewal at any time through Your mobile device's account settings (Google Play Store Subscriptions or Apple ID Subscriptions). Canceling a subscription stops future billing; You will retain access to Premium features until the end of Your current billing period.

Price Changes

The Company, in its sole discretion and at any time, may modify subscription fees. Any subscription fee change will become effective at the end of the then-current billing cycle. You will be provided with reasonable prior notice of any change in subscription fees to give You an opportunity to cancel Your subscription before such change becomes effective.

Refunds

Except when required by applicable law, paid subscription fees are non-refundable. Refund requests are handled directly by the store platform (Google Play Store or Apple App Store) in accordance with their respective refund policies.

3. Advertisements and Free Usage

The free version of the Application displays advertisements provided through third-party ad networks, primarily Google AdMob.

  • Ad Display: By using the free version of the Service, You agree to receive advertisements, including banner ads, interstitial ads, and rewarded video ads.
  • Ad-Free Option: You can permanently disable advertisements within the Application by maintaining an active Premium Subscription.
  • Third-Party Content: Advertisements may link to third-party websites or services that are not owned or controlled by the Company. We assume no responsibility for the content, privacy policies, or practices of any third-party ad providers or external sites.

10. Changes to These Terms

We reserve the right, at Our sole discretion, to modify or replace these Terms at any time. If a revision is material, We will make reasonable efforts to provide at least 30 days' notice prior to any new terms taking effect.
