Terms of Use
Updated: 30 October 2026
The short version: learn as much as you like, be fair to the Service and to other learners, and remember that Karo helps you learn a language but does not promise a particular result.
These Terms of Use (the "Terms") are an agreement between you and "Karo". They cover the Karo apps, the karo-learn.com website and the related services (together, the "Service"). By creating an account or using the Service, you agree to these Terms. If you do not agree, please do not use the Service. Our Privacy Policy explains how we process personal data and is part of how the Service works.
Who can use Karo
You must be at least 13 years old, or older if the law of your country requires it. Minors may use the Service only with the consent and supervision of a parent or guardian who accepts these Terms on their behalf. A subscription can be bought only by someone who may enter into that contract under the law of their country.
Your account
You sign in with Google or with your email address and give accurate information. Keep your access safe and do not pass it on. You are responsible for what happens in your account, so tell us straight away if you believe someone else has signed in. Your password is checked by a third-party sign-in provider; we never see or store it. You can delete your account at any time in the app (Profile, Settings, Delete account) or by writing to us.
The free plan and Karo Pro
You can learn for free: every course is open, a daily limit on new lessons applies, the number of lives is limited and ads are shown. Karo Pro is an optional paid subscription that lifts the daily limit, removes ads, and gives you unlimited lives and offline mode.
The price, the length of the period and any free trial are shown in the store before you subscribe. If you start a free trial, it turns into a paid subscription at the end of the trial unless you cancel in your store settings at least 24 hours before it ends. A subscription renews automatically for the period you chose until you cancel. You cancel in the Google Play or Apple App Store subscription settings; cancellation takes effect at the end of the period you have paid for.
The purchase is a contract between you and the store as seller of the subscription and between you and us for the Service. Payment, invoices and refunds are handled by the store under its rules, and your statutory rights as a consumer stay untouched. If you are a consumer in the European Union, you normally have a right to withdraw from a distance contract within 14 days; this right ends early for digital content or services once, at your request, we begin to provide them. Ask the store for how this works for your purchase. We may change prices and what a plan includes for the future and will tell you about important changes in advance; you can cancel before a change takes effect.
Lives, XP and achievements
Lives, experience (XP), streaks, achievements and other game elements exist only inside Karo. They have no monetary value, they cannot be exchanged for money or transferred to another user, and we may change the rules by which they are awarded.
Ads and third-party services
Ads from third-party ad networks are shown on the free plan, and the Service uses third-party services such as the stores, Google Firebase and Google AdMob. We do not control the content of other people's ads or of the sites they lead to, and those services have their own terms and privacy practices.
Rules of use
Use Karo fairly. You may not interfere with the Service or its security, gain access to it by unlawful means, build a copy or a competing product from it, reverse engineer it beyond what the law permits, resell access, inflate your results automatically, or use the Service to break the law or other people's rights. We may restrict or block accounts that abuse the Service.
Content and intellectual property
The Service, including its lessons, texts, illustrations, the carrot mascot, source code and design, belongs to us or our licensors and is protected by intellectual property law. The voices that read words aloud, the pronunciation dictionary and the open-source components we use are provided under their own licences, listed in the app (Settings, Licenses).
We grant you a personal, non-exclusive, non-transferable and revocable licence to use the Service for your own learning. You may not copy, distribute or create derivative works from our content, except where these Terms or the law allow it.
If you send us feedback or ideas, you allow us to use them to make Karo better, with no obligation to you and without naming you.
The Service is educational
Karo is a tool for learning, not a guarantee of results. We work hard to keep the lessons accurate and useful, but we do not promise any particular level of fluency, and Karo is not a replacement for lessons with a teacher where those are needed. The computer voices pronounce words as a machine does and can differ from a native speaker.
Availability and changes to the Service
We may update, change or discontinue features, and we may suspend the Service for maintenance. We aim for a Service that works as described and will keep it free of defects as the law requires for digital services. We will tell you in advance about changes that materially affect what you paid for, and if a change makes your use significantly worse you may cancel your subscription.
Warranty and liability
The free parts of the Service are provided as they are, without a warranty beyond what the law requires. For paid parts, your statutory rights when digital content or a digital service is defective stay untouched.
We are fully liable for intent and gross negligence, for injury to life, body or health, under mandatory product liability rules, and where we have given a guarantee. For slightly negligent breach of an obligation that is essential to the contract (one whose fulfilment makes proper performance possible and on which you can rely), our liability is limited to the damage that is typical and foreseeable for a contract of this kind. Otherwise we are not liable for slightly negligent breaches. This does not limit liability that the law does not allow us to limit, and it does not affect your statutory rights as a consumer.
We do not guarantee that the Service will run without interruption or error, or that your data will never be lost; keep your own notes of anything essential.
Ending your use
You can stop using Karo at any time and delete your account in the app. We may suspend or end your access if you materially breach these Terms or if the law requires it; if we do so for a paid subscription without a serious reason, we will refund the part of the period you paid for and did not use, where the store allows us to. Sections that by their nature should outlive the agreement, such as those on intellectual property and liability, continue to apply.
Changes to these Terms
We may update these Terms, for example when the Service or the law changes. We will announce important changes in the app or by email in good time and update the date at the top. If you do not agree with a change that affects your rights, you can stop using the Service and delete your account; if you keep using it after the change takes effect, you accept the updated Terms.
Governing law and disputes
These Terms are governed by the law of the country where we are established, excluding the UN Convention on Contracts for the International Sale of Goods. If you are a consumer, this choice does not take away the mandatory consumer protection rules of the country where you live, and you may bring a claim before the courts of that country. We are not obliged to take part in dispute resolution before a consumer arbitration board and have not agreed to do so, but we will always try to settle a complaint with you first: write to us.
General
If a provision of these Terms is invalid, the rest stays in effect and the invalid part is replaced by what comes closest to its purpose in a valid way. These Terms and the Privacy Policy are the entire agreement between you and us about the Service. You consent to receiving notices from us electronically, by email or in the app. We may transfer our rights and duties under these Terms to a successor of the business.
