Last updated: 7 November 2026
Provider and rights holder: Begali Khudaiberdiev (Худайбердиев Бегали), an individual based in Bishkek, Kyrgyz Republic ("we", "us"). Contact: khudaiberdievbegali71@gmail.com.
By installing or using the "Kaita" browser extension (Russian: «Кайта», Chinese: 凯塔), including beta versions (the "Extension"), you accept these Terms. If you do not agree, do not install the Extension, or remove it.
1. What the Extension is
The Extension is a learning tool for shadowing, phrase-by-phrase translation and simultaneous interpreting practice on YouTube videos. Speech recognition runs on your device (Whisper engine) or, in Chrome with the "Auto" or "Browser" setting, through the browser's built-in recognition service (Google). Data handling is described in the Privacy Policy.
2. Licence
- We grant you a non-exclusive, non-transferable, revocable licence to use the Extension for personal learning (or, for organisations, internal training) on your devices.
- You may not: sell, rent or distribute the Extension or copies of it; pass it or its parts off as your own; remove copyright notices; circumvent restrictions on paid features; or use the Extension to violate the law or third-party rights.
- The Extension includes open-source components (including transformers.js — Apache-2.0, onnxruntime-web — MIT, pinyin-pro — MIT, the Whisper model — MIT). They are governed by their own licences (see
THIRD_PARTY_LICENSES.txtin the Extension), and nothing in these Terms limits those licences.
3. Intellectual property
- The Extension's code, design, interface, texts, logo, name and other materials are owned by us or used under licence and are protected by law. The name "Kaita / Кайта / 凯塔" and the logo are our marks and may not be used for other products.
- Your data (saved phrases, attempts, notes) belongs to you and stays with you.
- If you send us ideas or feedback, we may use them without obligation to you.
4. YouTube and third-party content
- The Extension is not affiliated with, endorsed or sponsored by Google LLC or YouTube. YouTube is a trademark of Google LLC.
- When using YouTube you must comply with the YouTube Terms of Service. The Extension does not download video or audio and does not block ads. Do not use it to copy or redistribute others' content.
- Rights in videos and captions belong to their owners. Phrases you save are for your personal study only.
- We are not responsible for YouTube's availability, content or changes. If YouTube changes its website, some features may temporarily stop working.
5. Acceptable use
You may not: interfere with the Extension, websites or services; use the Extension for automated bulk data collection; or decompile or modify the Extension to bypass paid features or build a competing product, except where expressly permitted by law or by open-source licences.
6. Paid subscription (applies once a paid version is launched)
- Price and term. The price, billing period (monthly or yearly) and paid features are shown on the checkout page before payment (indicatively USD 5 per month). Prices may include taxes, or taxes are added at checkout depending on your country.
- Seller. Our order process is conducted by our online reseller and Merchant of Record (named on the checkout page), which is the seller of record, handles payments, taxes and billing enquiries. Its buyer terms also apply.
- Auto-renewal. Subscriptions renew automatically at the end of each period until cancelled. You can cancel at any time via the link in your receipt email or in the provider's customer portal. After cancellation, access continues until the end of the paid period.
- Free trial (if offered): unless you cancel before the trial ends, the first period will be charged.
- Refunds. If the subscription isn't right for you, contact khudaiberdievbegali71@gmail.com or the provider's support within 14 days of the first payment (or a renewal) and we will refund that period. This does not limit mandatory consumer rights in your country (e.g. the right of withdrawal in the EU/UK).
- Price changes. We announce price increases at least 30 days in advance. The new price applies from the next period. If you disagree, cancel your subscription.
- Free tier. Core features may remain free. We may change which features are free or paid, without reducing what you already paid for in the current period.
7. Future AI features
Optional AI analysis (if introduced) is enabled only with your separate consent and may be processed by a third-party AI provider as described in the Privacy Policy. AI output may contain errors. It is learning guidance, not a professional assessment or certification.
8. Disclaimer of warranties
The Extension is provided "as is". Speech recognition and pronunciation or translation scores are approximate and may be wrong (noise, accent, microphone quality, model limitations). To the extent permitted by law, we do not guarantee uninterrupted operation, compatibility with every browser or YouTube version, or any particular learning outcome.
9. Limitation of liability
To the maximum extent permitted by law, we are not liable for indirect damages, lost profits or loss of data (data is stored on your device, so use Export for backups). Our total liability is limited to the amount you paid us in the last 12 months, or USD 10 for the free version. Nothing in these Terms limits liability that cannot be limited by law (e.g. for wilful misconduct, or mandatory consumer rights).
10. Termination
You may stop using the Extension at any time by removing it. We may discontinue the Extension or its features and, if you breach these Terms, your access to paid features. If we discontinue the paid service entirely through no fault of yours, we will refund the unused part of the paid period.
11. Age
You must be at least 13 (or the age set by your local law, e.g. 16 in some EU countries) to use the Extension. Younger users need consent from a parent or guardian. Subscriptions must be purchased by an adult.
12. Changes to the Terms
We may update these Terms. The new version is published on this page with its date. We announce material changes in the Extension in advance. Continuing to use the Extension after changes take effect means you accept them.
13. Governing law and disputes
These Terms are governed by the laws of the Kyrgyz Republic, without prejudice to mandatory consumer protection rules of your country of residence. We first try to resolve disputes amicably: write to khudaiberdievbegali71@gmail.com and we will reply within 30 days. Failing that, disputes go to the courts at the rights holder's location (Bishkek), unless your local law entitles you to sue in your country of residence.
