Terms of Use

Effective: Last updated:

Contents

1. Agreement

These Terms of Use (“Terms”) govern your use of Just R (“the App”), a flashcard app for iPhone, iPad, Mac with Apple silicon and Apple Vision Pro, listed on the App Store as “Memorize Flash Card Maker” and under localized names. The App is developed and published by an independent software developer based in Ukraine, the seller shown on the App Store listing of the App (“we”, “us”, “the Developer”).

By downloading, installing or using the App, you agree to these Terms and to Apple’s Standard Licensed Application End User License Agreement described in section 18. If you do not agree, do not use the App. Our Privacy Policy explains how we handle personal data.

2. Licence

Subject to these Terms, we grant you a personal, limited, non-exclusive, non-transferable, revocable licence to install and use the App on Apple-branded devices that you own or control, for your own personal, non-commercial learning. The licence is subject to the Usage Rules in Apple’s Media Services Terms and Conditions, and the App may be used by other accounts associated with you through Family Sharing where Apple makes it available.

You may not copy, modify, distribute, sell, rent or sublicense the App, or reverse-engineer it except where the law allows this despite this restriction.

3. Your Account

You can use many features without an account. To sync your decks between devices you can sign in with Apple, an email address or a phone number. You are responsible for keeping your sign-in details secure and for activity under your account. Tell us at support@just-r.app if you think someone else has accessed it. You can delete your account at any time in the App’s settings.

4. Your Content

The decks, cards, notes and images you create (“Your Content”) belong to you. You give us a limited licence to store, copy and display Your Content only as needed to provide the App, for example to sync it to your other devices or to send card text to an AI service you asked to use. We do not publish Your Content.

You are responsible for Your Content and confirm that you have the right to use it. Do not add content that is illegal, infringes someone else’s rights, or contains other people’s personal data without permission. Keep your own copies of important content: you can export it to CSV at any time.

5. AI Features

The App offers optional features that use artificial intelligence provided by OpenAI to generate images, read text aloud and show the context of words and phrases. They run only after you allow them.

  • Output can be wrong. Generated translations, context, pronunciation and images may be inaccurate, incomplete or unsuitable. Check them before you rely on them.
  • Your requests. Do not use AI features to create content that is illegal, harmful, hateful, sexual involving minors, or that infringes others’ rights. Your requests must also follow OpenAI’s usage policies.
  • Rights in output. As between you and us, you may use the output generated for your cards for your personal learning. Similar output may be generated for other users.
  • Availability. AI features depend on a third-party service and may change, be limited or stop working.

6. A Learning Tool, Not a Guarantee

Just R helps you organize and review what you learn, including reminders based on the Ebbinghaus forgetting curve. How well and how fast you learn depends on you. We do not guarantee any learning result, level, exam score or certificate. Reminders are delivered by your device’s notifications or Calendar and may be delayed or blocked by your settings.

7. Premium, Prices and Auto-Renewal

The App is free to download. The free version has limits on the number of decks, cards and categories and shows ads. Just R Premium removes these limits and adds features such as ready-made decks, decks with video, AI voice and the context of words and phrases.

Premium is offered as:

  • Auto-renewable subscriptions: 1 week (USD 0.99), 1 month (USD 2.99), 3 months (USD 7.99), 6 months (USD 16.99) and 1 year (USD 29.99);
  • Premium for life: a one-time purchase (USD 39.99) that unlocks Premium on your Apple Account without renewal.

Separate in-app purchases are also offered: a single ready-made deck (USD 0.99) and AI image generation (USD 0.29).

The prices above are US App Store prices. Your local price and currency are shown by the App Store before you buy and may differ. There is no free trial.

  • Payment is charged to your Apple Account when you confirm the purchase.
  • A subscription renews automatically for the same period and price unless you turn off auto-renewal at least 24 hours before the end of the current period. Your account is charged for renewal within the 24 hours before the current period ends.
  • Manage or cancel subscriptions in your Apple Account settings (Settings → your name → Subscriptions). Deleting the App does not cancel a subscription. After you cancel, Premium stays active until the end of the period you paid for.
  • To use Premium on another device, restore purchases in the App with the same Apple Account.
  • We may change prices or what Premium includes for future periods. Price changes for subscriptions take effect only with the notice and consent Apple requires.

We do not process payments and cannot issue refunds. Refunds are requested from Apple at reportaproblem.apple.com and decided by Apple under its policies. Nothing in these Terms limits rights to withdraw from or cancel a purchase that you have under mandatory consumer law.

8. Coins and Other Virtual Items

The App may let you earn coins or other virtual items, for example to unlock ready-made decks. Virtual items have no cash value, cannot be exchanged for money, transferred or sold, and are not your property; you have a limited licence to use them in the App. We may change how they are earned or used. They may be lost if you delete your account or the App is discontinued, except where the law requires otherwise.

9. Advertising

The free version shows ads provided by third parties, mainly Google AdMob. We are not responsible for the content of ads or for third-party products and websites they lead to. How ads use data, and your choices, are described in the Privacy Policy.

10. Ready-Made Decks

Ready-made decks, including decks with video, are provided for personal study. You may save and use them in the App, but you may not copy, extract, publish or sell their contents outside the App. We try to keep them accurate but do not guarantee that every translation or example is correct, and we may update or remove decks.

11. Acceptable Use

You agree not to:

  • use the App for anything unlawful or to harm others;
  • try to gain unauthorized access to the App, our services, other users’ accounts or our providers’ systems;
  • interfere with the App’s security, overload it, or use bots or scripts to access it;
  • bypass purchases, limits or technical protections;
  • use the App to store or spread content that is illegal, infringing, abusive or malicious.

12. Intellectual Property

The App, its design, code, texts, ready-made decks, graphics and the name and logo “Just R” belong to the Developer or its licensors and are protected by law. Apart from the licence in section 2, these Terms give you no rights to them. If you send us feedback or ideas, we may use them without obligation to you.

13. Third-Party Services

The App relies on third-party services, including Apple, Google Firebase, Google AdMob, Mixpanel, Meta and OpenAI. Their terms and privacy policies apply to their services, and we are not responsible for them. Links to third-party websites are provided for convenience only.

14. Updates and Availability

We may update the App to fix problems, add or change features, or comply with the law. Some updates may be needed to keep using the App or its online features. We may also stop offering the App or a feature. If we discontinue Premium features you paid for, we will give reasonable notice where we can. Features that need the internet, such as sync, ready-made decks and AI, may be unavailable at times.

15. Disclaimer of Warranties

To the maximum extent permitted by law, the App is provided “as is” and “as available”, without warranties of any kind, express or implied, including merchantability, fitness for a particular purpose, accuracy and non-infringement. We do not warrant that the App will be uninterrupted, error-free or free of data loss. Some jurisdictions do not allow these exclusions, so some may not apply to you.

16. Limitation of Liability

To the maximum extent permitted by law, the Developer is not liable for any indirect, incidental, special, consequential or punitive damages, or for loss of data, profits or goodwill, arising from your use of or inability to use the App. Our total liability for any claim relating to the App is limited to the amount you paid for the App and in-app purchases in the 12 months before the claim, or USD 50 if that is greater. Nothing in these Terms limits liability that cannot be limited by law, such as for death or personal injury caused by negligence, fraud, or your statutory rights as a consumer.

17. Indemnity

To the extent permitted by law, you agree to indemnify the Developer against claims, losses and expenses (including reasonable legal fees) arising from Your Content or your breach of these Terms.

18. Apple’s Standard EULA and Apple-Specific Terms

Your use of the App is also governed by Apple’s Standard Licensed Application End User License Agreement (“Apple’s Standard EULA”), available at https://www.apple.com/legal/internet-services/itunes/dev/stdeula/, which is incorporated into these Terms by reference. If these Terms and Apple’s Standard EULA conflict, Apple’s Standard EULA applies to the extent of the conflict, except where these Terms give you more rights.

You acknowledge that:

  • these Terms are concluded between you and the Developer only, not with Apple, and the Developer, not Apple, is solely responsible for the App and its content;
  • your licence to use the App is non-transferable, is limited to Apple-branded products that you own or control, and is subject to the Usage Rules in Apple’s Media Services Terms and Conditions;
  • Apple has no obligation to furnish any maintenance or support services for the App. The Developer is solely responsible for maintenance and support; contact support@just-r.app;
  • if the App fails to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price (if any) for the App; to the maximum extent permitted by law, Apple has no other warranty obligation with respect to the App, and any other claims, losses, liabilities, damages, costs or expenses attributable to a failure to conform to a warranty are the Developer’s responsibility;
  • the Developer, not Apple, is responsible for addressing any claims by you or a third party relating to the App or your possession and use of it, including product liability claims, claims that the App fails to conform to legal or regulatory requirements, and claims under consumer protection, privacy or similar laws;
  • if a third party claims that the App or your possession and use of it infringes that third party’s intellectual property rights, the Developer, not Apple, is solely responsible for the investigation, defence, settlement and discharge of that claim;
  • you represent that you are not located in a country subject to a U.S. Government embargo or designated by the U.S. Government as a “terrorist supporting” country, and that you are not listed on any U.S. Government list of prohibited or restricted parties;
  • you must comply with applicable third-party terms of agreement when using the App, such as the terms of your mobile carrier or internet provider;
  • Apple and Apple’s subsidiaries are third-party beneficiaries of these Terms, and upon your acceptance of these Terms, Apple will have the right (and will be deemed to have accepted the right) to enforce them against you as a third-party beneficiary.

Developer and contact for questions, complaints or claims about the App: the Developer named as the seller on the App’s App Store listing, Ukraine, support@just-r.app.

19. Termination

You may stop using the App and delete your account at any time. We may suspend or end your access to online features if you seriously or repeatedly breach these Terms, or if required by law. Sections that by their nature should survive termination (including 4, 12 and 15–22) continue to apply.

20. Governing Law and Disputes

These Terms are governed by the laws of Ukraine, without regard to conflict-of-law rules. If you are a consumer living in another country, you also keep the protection of the mandatory laws of your country, and you may bring a claim in the courts where you live. Before filing any claim, please contact us at support@just-r.app so we can try to resolve the issue informally.

21. Changes to These Terms

We may update these Terms. The “Last updated” date at the top shows the latest version. If a change is material, we will tell you in the App or on this website before it takes effect. If you keep using the App after a change takes effect, you accept the updated Terms; if you do not agree, stop using the App and cancel any subscription.

22. Severability and Entire Agreement

If any part of these Terms is found unenforceable, the rest remains in effect. These Terms, the Privacy Policy and Apple’s Standard EULA are the entire agreement between you and us about the App. Our failure to enforce a provision is not a waiver of it.
