These terms apply when you download, install or use arcoco, the vocabulary-building app operated by Arcoco Ltd ("arcoco", "we", "us"), on iPhone or Android (the "app"). By using the app you agree to these terms. If you do not agree, do not use the app.

On the App Store, Apple's standard licence terms also apply to the copy of the app you download from Apple. On Google Play, Google's terms apply to the store transaction. Where those store terms and these terms both apply, these terms govern your use of the app itself.

1. Who we are

arcoco is operated by Arcoco Ltd, a company registered in England and Wales (company number 10951526), based in the United Kingdom. For questions about these terms, contact support@arcocoapp.com.

2. Your licence to use the app

We grant you a personal, non-exclusive, non-transferable, revocable licence to install and use the app on devices you own or control, for your own personal, non-commercial learning. You may not copy, modify, distribute, sell, rent, reverse-engineer or decompile the app, or extract its word catalogue, images or audio for use outside the app, except where the law allows this despite these terms.

3. Using arcoco

arcoco is a practice tool. It suggests words and explanations to help you communicate more clearly; it is not a substitute for professional language teaching, and we do not promise any particular learning outcome. You are responsible for how you use the words you practise.

You must be at least 13 years old to use the app. If you are under 18, you must have your parent's or guardian's permission.

You agree not to use the app in a way that is unlawful, that interferes with the app or other users, or that attempts to gain unauthorised access to our systems or those of our service providers.

4. Free use and arcoco Plus

You can play a limited number of games each day for free. arcoco Plus is an optional paid upgrade that unlocks unlimited games and automatic streak protection. It is sold as an auto-renewing monthly or yearly subscription and, where offered, as a one-time Lifetime purchase.

Where a feature is described in the app as not yet available on your platform, it is not part of what you are buying on that platform.

5. Your progress

Your practice progress is stored on your device. Where the app offers optional progress saving through Apple or Google sign-in, you can choose to save progress to our servers so it can be restored on another device. We take reasonable care of saved progress but do not guarantee it will never be lost; keep the app updated and use progress saving where it is offered if your progress matters to you.

6. Our content

The app, its word catalogue, explanations, illustrations, sounds, characters, design and code are owned by Arcoco Ltd or our licensors and are protected by copyright and other intellectual property laws. Nothing in these terms transfers any of those rights to you.

7. Changes to the app

We may update, change or withdraw features of the app, including the word catalogue, game modes and pricing of future purchases, at any time. If a change materially reduces what an active subscription provides, you may cancel and any refund will be handled under the relevant store's policy.

8. Availability

We aim to keep the app working but do not promise that it will always be available or free of errors. The app depends on your device, its operating system and, for some features, third-party services such as Apple, Google, RevenueCat and Firebase.

9. Our responsibility to you

If we fail to comply with these terms, we are responsible for loss or damage you suffer that is a foreseeable result of our breach or our failure to use reasonable care and skill. We are not responsible for loss that is not foreseeable, for business losses, or for loss caused by events outside our reasonable control.

Nothing in these terms excludes or limits our liability for death or personal injury caused by our negligence, for fraud, or for anything else that cannot be excluded or limited by law. Your statutory rights as a consumer are not affected.

10. Ending the agreement

You can stop using the app at any time by deleting it. We may suspend or end your access to the app if you seriously breach these terms. Ending the agreement does not affect any purchase already made through Apple or Google, which continues to be governed by that store's terms.

11. Privacy

How we handle your information is explained in our Privacy Policy, which forms part of these terms.

12. Changes to these terms

We may update these terms from time to time. We will update the "Last updated" date at the top of this page and, for material changes, tell you in the app before they take effect. If you keep using the app after a change takes effect, the updated terms apply.

13. Law and disputes

These terms are governed by the law of England and Wales. If you live in Scotland or Northern Ireland, you can also rely on the mandatory consumer laws of your country, and you may bring proceedings in the courts there. Otherwise, the courts of England and Wales have jurisdiction, and this does not affect your rights under the law of the country you live in.
