Terms of Service

1. Acceptance of These Terms

These Terms of Service form an agreement between you and AMBERSOFT LABS - FZCO, the company behind Klee. If you do not agree to them, do not use the service. If you use Klee for an organization, you confirm that you have authority to accept these Terms for that organization.

2. Eligibility and Accounts

Klee's AI features, trial credits and purchases are for adults: you must be at least 18 years old to use them, in every country. Eligibility is decided from the age range you tell us; we do not ask for your date of birth. You may skip the age question when you sign up, but AI features, trial credits and purchases are available only after you confirm that you are 18 or older. If you tell us you are 13 to 17, you may keep using your collections and the exercises, and those three stay unavailable, as do live lessons with other people. Klee accounts are not for children under 13: if you tell us you are under 13, we cannot keep your account, so the app offers to delete it together with all of its data, and offers again each time you open Klee for as long as the account exists. We ask for your country of residence when you make a purchase, because it determines the plans and currency offered to you.

Only adults aged 18 or over can purchase Klee Premium. You are responsible for providing accurate account information, keeping your login credentials secure, and for activity under your account. Tell us promptly if you believe your account has been compromised.

3. The Klee Service

Klee helps you build your own vocabulary in a language you are learning. You create word cards, and Klee schedules reviews, offers practice exercises, tracks progress, and can use artificial intelligence to fill in translations, transcriptions, examples, and pronunciation.

Klee is a learning tool. It is not a substitute for a teacher, a course, or a certification, and we do not promise a particular level of language ability, exam result, or speed of progress.

4. Your Content

The words, translations, notes, examples, images, and recordings you add remain yours. You give us permission to store, process, and display that content only so that we can operate Klee for you, including sending the necessary parts to the service providers listed in our Privacy Policy. You confirm that you have the right to use the content you upload and that it does not break the law or infringe anyone else's rights.

5. AI and Automated Features

Klee can generate translations, transcriptions, examples, and high-quality pronunciation, and can recognize your speech in the Speak exercise. These features run through third-party providers described in our Privacy Policy. AI output can be wrong or incomplete, so please check anything important before relying on it.

Speech recognition is off by default and starts only after you turn it on and grant microphone permission. You can turn it off again at any time in Settings.

6. Devices

A Premium subscription may be used on up to five active devices or browsers at a time. If you reach that limit, you can release one of them yourself and continue on the new device. We do not identify your physical device by hidden fingerprinting and we do not merge accounts by IP address. To keep you signed in and to work offline, Klee stores your session, your settings, an offline copy of your words and cached audio on your own device, and our website sets a short-lived cookie only while you sign in with Google. We use no advertising cookies and no analytics or tracking services; section 4 of our Privacy Policy explains this in full.

7. Subscriptions and Billing

Where you can buy. Klee Premium is sold in three places: on our website, where payments are processed by Stripe; in the Klee app for iPhone, where the purchase goes through Apple's App Store; and in the Klee app for Android, where it goes through Google Play. Wherever you buy, Premium is unlocked on your Klee account and works on up to five devices at a time (see section 6). Premium is available in supported countries, which are shown at checkout. If Premium is not available where you are, you can keep using the free tier.

Where you buy is where you are billed. Billing, renewal, cancellation, and refunds are handled by the place you bought from: Stripe for the website, Apple for the App Store, Google for Google Play. We cannot change or refund a purchase made through Apple or Google, and Apple and Google cannot change one made on our website. If you are not sure where you bought, write to us and we will point you to the right place.

Automatic renewal. Premium is sold as a monthly or an annual subscription and is billed in advance. Your subscription renews automatically at the end of each billing period until you cancel it. A subscription bought in the app renews unless you cancel it at least 24 hours before the end of the current period, and the store charges you for the next period within the 24 hours before it starts. The price, currency, billing period, and the date of your first charge are shown before you confirm the purchase.

Free trial. A new account, once its owner has confirmed an age of 18 or over, gets a free trial of 50 AI credits, once per person. The free trial is not a subscription: it costs nothing, it never turns into a paid plan by itself, and nothing is charged when it ends. Buying a subscription is a separate step that you confirm yourself, and the price and the date of the first charge are shown before you do. If you buy during the free trial, your paid subscription starts right away.

AI credits. High-quality pronunciation, Statistics and the other AI features are unlocked by having AI credits on your account, not by your subscription status on its own - Smart Learning and exercises stay available to everyone regardless of credits. Library words above level A2 (B1 to C2) come with a subscription. Each confirmed monthly billing period adds 350 AI credits; each confirmed annual period adds 4,000 AI credits for that paid year. Credits do not expire and carry over for as long as your account is active. AI credits are a usage allowance inside Klee: they are not money, have no cash value, and cannot be exchanged, transferred, or withdrawn. Credits may also be granted outside a subscription - for example, through a promotional code - and work the same way.

Price changes. If we change the price of a subscription, the new price applies from your next billing period, and we will tell you in advance so that you can cancel if you do not agree. For a subscription bought through the App Store or Google Play, the store tells you as well and, where its rules require it, asks for your agreement before the new price applies.

8. Cancellation and Refunds

Cancelling. You can cancel at any time. Cancellation stops the next renewal, and you keep Premium until the end of the period you have already paid for. Where you cancel depends on where you bought:

• Bought on our website: open the Premium screen in Klee and tap Manage subscription, or write to us.
• Bought on iPhone (App Store): open Settings on your iPhone → your name (Apple ID) → Subscriptions → Klee → Cancel subscription.
• Bought on Android (Google Play): open the Play Store → your profile picture → Payments and subscriptions → Subscriptions → Klee → Cancel subscription.

Deleting the Klee app from your phone does not cancel the subscription, and neither does deleting your Klee account. Outside the refund window below, we do not provide partial refunds for unused time except where the law requires it.

Refund window for purchases on our website. If you ask within 7 days of the first payment for a monthly subscription, or within 14 days of the first payment for an annual subscription, we refund the full amount and end the subscription. If more than half of the AI credits for that period have already been used, the refund is decided case by case. Renewal payments are not covered by this window. To ask for a refund, write to our support.

Refunds for purchases in the app. A purchase made through the App Store or Google Play is refunded by Apple or Google under their own rules, and we cannot issue that refund ourselves. Ask Apple at reportaproblem.apple.com, or Google from your order history in the Play Store. The 7-day and 14-day windows above apply to website purchases only. When Apple or Google refunds a purchase, the AI credits that purchase added are removed from your account.

If something goes wrong. If a payment does not look right, write to support@kleeapps.com and we will look into it. Beyond that, refunds are handled according to the mandatory consumer rights that apply to you and the rules of the payment provider. Nothing in these Terms limits rights you have under law that cannot be waived.

If you stop paying. Your words, collections, and learning history are not deleted when a subscription ends. You keep full access to the free tier and your progress is preserved. If you subscribe again, learning continues where it stopped.

Deleting your account does not cancel your subscription. Cancel the subscription first, in the place you bought it, or write to us and we will help.

9. Acceptable Use

Please use Klee for learning. You may not use it to:

• break the law, infringe intellectual property, or violate another person's rights;
• harass, threaten, exploit, or distribute harmful or deceptive content;
• probe, bypass, disrupt, or gain unauthorized access to the service or another user's data;
• bypass payment, entitlement, or usage limits, or attempt to obtain paid features without paying;
• introduce malware, automate abusive traffic, scrape the service at scale, or interfere with normal operation;
• resell or misrepresent Klee without our written permission.

10. Sharing and Live Lessons

Some features let you share collections, invite participants, or collaborate in live lessons. Creating, hosting and joining a live lesson does not require a subscription. You control what you share and are responsible for the content and people you invite. Content shared with others may be copied by them, so do not share information you want to keep private.

Words collected during a lesson become cards in your own collection only after you review and confirm them.

How to behave in a lesson. A live lesson is a shared space, so treat the people in it with respect. Bullying, threats, hate, sexual content, spam, and fishing for someone's personal details (phone number, address, passwords, payment information) are not allowed, whether in words you add, in what you say, or in what you show.

Report and block. Every participant, including the host, can report or block another person straight from the list of people in the lesson. Blocking takes effect immediately and works both ways: that person cannot join your lessons and you cannot join theirs. Only you can lift a block, in Settings → Blocked people. A report also blocks the person and goes to our support team with the lesson ID and your note. We review every report within 24 hours, and we may remove content, end the lesson, or restrict or close the account of someone who breaks these rules.

11. Our Intellectual Property

Klee, its name, its mascot, its interface, its ready-made word sets, and its software belong to us or to our licensors. These Terms let you use Klee but do not transfer ownership to you.

12. Third-Party Services

Klee relies on third-party services for authentication, hosting, payments on the website and in the app stores, AI, media, and audio. Their own terms and privacy policies may apply when you use those features. We are not responsible for third-party services outside our control.

13. Availability and Changes

We work to keep Klee available and reliable, but we do not promise uninterrupted or error-free access. We may add, change, suspend, or discontinue features, including for maintenance, security, legal, or product reasons. If a change materially reduces what a paid subscription gives you, we will tell you in advance and you may cancel.

Some parts of Klee work offline with the data already on your device. AI features and anything that needs our servers require a connection.

14. Ending Your Use

You may stop using Klee at any time and can delete your account in Profile → Delete account (step by step at kleeapps.com/delete-account). Deleting your account removes your personal content according to our Privacy Policy, and we keep the financial records we are legally required to keep.

We may restrict or terminate access if you materially violate these Terms, create risk for users or the service, or if required by law. When practical, we will provide notice. If we end your access without cause while you have paid for a period that has not finished, we will refund the unused part.

15. Disclaimers

To the extent permitted by law, Klee is provided “as is” and “as available.” We disclaim implied warranties, including merchantability, fitness for a particular purpose, and non-infringement. Nothing in these Terms excludes warranties or rights that cannot legally be excluded.

16. Limitation of Liability

To the extent permitted by law, Klee and its contributors will not be liable for indirect, incidental, special, consequential, or punitive damages, or for loss of data, profits, goodwill, or business opportunity arising from use of the service. Our total liability for claims relating to Klee will not exceed the amount you paid us for the service during the 12 months before the claim.

Nothing here excludes liability that cannot be excluded by law, including liability for death or personal injury caused by negligence, for fraud, or under mandatory consumer protection law.

17. Changes to These Terms

We may update these Terms as Klee changes. If a change is significant, we will provide notice in the app or by email when appropriate. Continuing to use Klee after updated Terms take effect means you accept them. The date at the top of this page always shows the current version.

18. Governing Law and Disputes

These Terms are governed by the laws of the United Arab Emirates as applied in the Emirate of Dubai, and the courts of Dubai have jurisdiction. If you are a consumer, this does not deprive you of the protection of the mandatory consumer laws of your country of residence, which continue to apply.

Before starting any formal proceedings, please write to legal@kleeapps.com so that we can try to resolve the matter directly.
