Terms of Use - Grammar TOP

Effective Date: October 3, 2026
Last Updated: October 3, 2026

1. Acceptance of Terms

These Terms of Use constitute a binding agreement between you and Avantis, s.r.o. (“Grammar TOP,” “we,” “us,” or “our”). The following terms and conditions govern your access to and use of the Grammar TOP app for learning English grammar on iOS, iPadOS, macOS and Android, the website at https://www.supergrammar.info, and all related services, features, and content (collectively, the “Services”).

Please read these Terms of Use carefully before using the Services. By downloading, accessing, or using the Services, you acknowledge that you have read, understood, and agree to be bound by these Terms of Use and our Privacy Policy available at https://www.supergrammar.info/?page_id=475, which is incorporated into these Terms by reference.

If you do not agree to these Terms of Use or the Privacy Policy, you must not access or use the Services.

2. App Store and Google Play

If you downloaded the app from Apple’s App Store (including on a Mac), your license to use the app is governed by Apple’s Licensed Application End User License Agreement (the “Standard EULA”). These Terms supplement the Standard EULA. If these Terms conflict with the Standard EULA, the Standard EULA prevails for apps downloaded from the App Store.

If you downloaded the app from Google Play, these Terms are the license terms for the app, and Google Play’s terms of service also apply to your download and purchases.

3. Eligibility

The Services are intended for individuals who are at least 13 years of age. If you are under the age of legal majority in your country, you may use the Services only with the involvement of a parent or legal guardian, who must agree to these Terms on your behalf and make or approve any purchase.

4. Changes to Terms

We reserve the right to modify these Terms of Use at any time. When we make changes, we will update the “Last Updated” date at the top of this document and post the new version on this page. For material changes, we will also notify you through an in-app notification.

Changes become effective 30 days after notification. Your continued use of the Services after this period constitutes your acceptance of the modified Terms. A change does not reduce what you receive for a subscription period you have already paid for. We encourage you to review these Terms periodically to stay informed of any updates.

5. No Account; Your Progress

You do not need an account, name, email address or password to use the app. The course content is built into the app and works offline.

Your progress, mistakes, settings and reminder time are stored only on your device. We do not keep a copy of them. If you delete the app, use “Delete all data” in the settings, or move to a new device, your progress cannot be restored.

Earlier versions of Grammar TOP (3.x and earlier) used accounts. The current version does not use those accounts, and progress saved in them is not transferred to it.

6. Free Content, Subscriptions and Payment

6.1 Free Content and Premium

Part of the course is free with no time limit: the first topics of every level, the first lesson of every other topic, and the reference tables. Access to the rest of the course and to some practice features (“Premium”) requires a subscription or a one-time purchase. We may change which parts of the course are free; such a change does not reduce what you receive while you have Premium.

Premium is offered as:

An annual subscription, with a 7-day free trial for new subscribers where offered
A monthly subscription
A lifetime purchase, a one-time payment that is not renewed

Prices are shown in the app before you buy and may differ between countries.

6.2 Free Trial

When you start a free trial:

You will have access to all Premium features for 7 days at no charge
Your subscription will automatically convert to a paid annual subscription at the end of the trial period unless you cancel at least 24 hours before the trial ends
The app shows the date of the first charge before you start the trial
A free trial is available once per store account, as determined by the store’s rules

6.3 Payment Processing

All purchases are made through Apple’s App Store or Google Play and are processed by Apple or Google. By purchasing Premium, you agree to the terms and conditions of the store you buy from. We do not receive or store your card or bank details.

6.4 Subscription Fees and Billing

Subscription fees are charged to your App Store or Google Play account in advance on a recurring basis (monthly or annually, depending on your selected plan)
Your subscription will automatically renew at the end of each billing period at the then-current price unless you cancel at least 24 hours before the end of the current period
Taxes are applied by the store according to its rules and the law of your country
Prices are subject to change; the store will notify you of a price increase for your subscription in advance and, where its rules or the law require, ask for your consent

6.5 Right of Withdrawal and Refund Policy

Under European Union consumer protection law, you may have the right to withdraw from a contract for digital content within 14 days. Because you buy Premium from Apple or Google, this right, and any refund, is handled by the store under its own policies. When you buy, the store may ask you to confirm that you request immediate access to Premium and that you therefore lose your right of withdrawal.

We cannot issue refunds for purchases made through the App Store or Google Play ourselves. To request a refund, use reportaproblem.apple.com for App Store purchases or your Google Play order history for Google Play purchases.

Cancellation During Free Trial:
You may cancel your subscription at any time during the 7-day free trial period without being charged, as long as you cancel at least 24 hours before the trial ends.

Cancellation After Trial:
Once your paid subscription begins, you may cancel it at any time. Except where the store’s refund policy or applicable law provides otherwise, you will not receive a refund for fees already paid, and your subscription will remain active until the end of the current billing period.

6.6 Subscription Cancellation

You cancel your subscription through the store, not in the app:

On iPhone, iPad and Mac: Settings > your name > Subscriptions
On Android: Google Play > Payments & subscriptions

The app links to these pages from its Profile tab.

Deleting the app does not cancel your subscription.

Upon cancellation:

Your access to Premium will continue until the end of your current billing period
You will not be charged for subsequent billing periods

6.7 Failed Payments

If a renewal payment fails, the store may try to process it again and may give you a grace period under its rules. If payment is not successfully processed, your access to Premium may end until it is.

6.8 Restoring Purchases and Earlier Purchases

Premium is linked to your App Store or Google Play account, not to your device. To get Premium on a new device or after reinstalling the app, sign in to the same store account and tap “Restore purchases” in the app. A purchase made on the App Store unlocks Premium on iPhone, iPad and Mac but not on Android, and a purchase made on Google Play does not unlock Premium on Apple devices.

Subscriptions and lifetime purchases bought in earlier versions of Grammar TOP continue to give Premium in the current version for as long as they are active (a lifetime purchase, for as long as we offer the app). If we stop selling a plan, an active subscription to it continues until it is cancelled or ended by the store, and a lifetime purchase remains valid.

“Lifetime” means for as long as we offer the app, not for your lifetime.

7. Use of Services and Acceptable Use

7.1 License Grant

Subject to your compliance with these Terms (and, for apps downloaded from the App Store, the Standard EULA), we grant you a limited, non-exclusive, non-transferable, revocable license to access and use the Services for your personal, non-commercial use, on devices you own or control as permitted by the store you downloaded the app from.

The Services do not award certificates or qualifications and are not affiliated with or endorsed by any examination or exam board. We do not guarantee any particular result, such as reaching a level, passing an exam, or a grade or score.

Example sentences are read aloud by the speech engine built into your device, which is provided by the device’s operating system.

10. Third-Party Services and Links

10.1 Third-Party Services

The Services rely on third-party services, including Apple’s App Store and Google Play for downloads and payments, and service providers for subscription management and usage analytics described in the Privacy Policy. Your use of the App Store and Google Play is subject to their respective terms and privacy policies.

10.2 Third-Party Links

The Services may contain links to third-party websites or resources. We do not endorse and are not responsible for:

The availability, accuracy, or content of third-party websites
Any products, services, or content available through third-party sites
The privacy practices of third-party sites

Your interactions with third-party websites are solely between you and the third party, and you access them at your own risk.

While you have Premium, you have access to the full course as it is at that time. If we decide to stop offering the app, we will tell you in the app or on our website in advance where possible. The course content built into the app will keep working on devices where it is installed, but we cannot promise that it will work with future operating systems.

If you are a consumer residing in the European Union, nothing in these Terms affects your statutory rights as a consumer under applicable EU law, including your right to bring proceedings in the courts of your country of residence.

The remaining provisions shall continue in full force and effect.

18.3 Waiver

Our failure to enforce any right or provision of these Terms shall not constitute a waiver of such right or provision. Any waiver must be in writing and signed by an authorized representative of Avantis, s.r.o.
