1. Operator, acceptance and eligibility

The Kawn Ad-Din project (kawnaddin.com) is run by a group of scholars located in different countries (“we”).

These Terms govern the use of the site and the purchase of paid services. You accept them by ticking the box when you sign up, by continuing to use the site after the Terms are updated, and by confirming them before a payment. If you do not agree, please do not use the site.

You must be an adult to register and to buy. Minors may use the free content without registering.

2. Accounts and security

One person — one account. Give a real e-mail address that you control and keep your password secret; you can also switch on two-factor authentication. You are responsible for what is done under your account. If you suspect unauthorised access, write to support@kawnaddin.com at once. A paid plan is personal: you may not share it with other people or resell access to it.

3. Rights holder and copyrighted works

The content of the site includes intellectual property created through the considerable work of the project’s compilers, including:

• translations into other languages;
• the scholarly apparatus: takhrij, footnotes, commentary, references;
• continuous numbering and classification of masa’il, the structure and arrangement of the collections;
• digitisation, proofreading and textual reconstruction of the sources;
• design, program code, layout and the organisation of the database.

These materials are protected by copyright and by the database maker’s right. The exclusive rights belong to the rights holder of the Kawn Ad-Din project.

4. Classical primary sources

Primary sources in Arabic (the Quran, hadith, classical texts of fiqh) are in the public domain, and we claim no rights to these texts themselves. However, the editorial layer built on them — translations, apparatus, numbering, the verified electronic edition and structure — is the result of our work and is protected.

5. What is permitted

• reading and studying the materials for personal, educational and religious purposes;
• manually copying and saving individual passages for personal use;
• sharing individual materials through the built-in buttons (WhatsApp, Telegram, e-mail) and links;
• quoting passages of reasonable length with mandatory attribution of the source (kawnaddin.com).

6. What is prohibited

Without the prior written permission of the rights holder, the following is prohibited:

• automated data collection (scraping, crawling, by bots, scripts or API enumeration);
• bulk or systematic downloading of materials, exporting the database or a substantial part of it;
• creating mirrors, copies of the site or derivative databases based on our content;
• commercial use, resale or distribution of the materials;
• removing or distorting statements of authorship and source;
• circumventing technical measures that restrict access or the volume of downloads;
• sharing a paid plan with other people or reselling access to it.

7. Religious content, AI search and the cycle tracker

The materials are provided for reference and education. For practical religious decisions, please consult qualified scholars. The project strives for accuracy in conveying the texts, but does not guarantee the absence of digitisation or translation errors. If you notice an error in a text or a translation, please write to us at info@kawnaddin.com — we will check and correct it.

AI search. AI search is powered by a third-party large language model. AI answers are built only from quotations from our library and may contain errors; they are not fatwas. Always rely on the quoted texts and, for practical decisions, on qualified scholars.

Cycle (hayd) tracker. The tracker keeps your records and calculates a status by the rules of fiqh set in it. It is a reference tool: not a fatwa and not medical advice, and it does not replace a mufti or a doctor. Health data is processed only with your separate explicit consent (see the Privacy Policy).

8. Paid services

The content of the site — books, fatwas, hadith, the Quran, the dictionary and translations — is free and stays free. We sell access to services: smart and AI search, the cycle tracker with mufti guidance, the halal product scanner, unlimited calculators and notifications. What each plan includes is listed on the Pricing page and applies from activation.

Plans. Basic, Standard, Research and Research+ are sold for one year (12 months) from payment.

• Cryptocurrency: a one-time payment. There is no automatic renewal, and we never charge you again without your action. Renewing the same plan before it expires adds a new year after the end of the current term; moving to a higher plan starts its year on the day of payment.
• Bank card (where offered): an annual subscription that renews automatically for another year, at the price shown at the time of renewal, until you cancel it. You can cancel at any time in your account (“Subscription” tab) or by writing to support@kawnaddin.com: cancellation stops future charges and the plan stays active until the end of the paid year. We remind you by e-mail before each renewal charge. Moving to a higher plan starts its year on the day of payment.

AI budget. AI search is paid from an AI budget included in plans and available in separate top-up packs. It is shown as a percentage because the number of questions is approximate: requests of different depth cost different amounts. A top-up lasts until the end of your subscription and at least 6 months from purchase. When the budget is spent, your plan and its other features continue; AI search resumes after a top-up. An unused budget expires at the end of its term and is neither refunded nor paid out.

Trial and researcher mode. A registered user with a confirmed e-mail receives a one-time AI trial budget. Researcher mode for holders of Research+ is enabled on request, free of charge, at our discretion; it widens the volume of AI output and does not add budget.

We may change prices, plans and limits for future purchases; this does not affect services you have already paid for.

9. Prices, payment and taxes

Prices are in US dollars (USD) and shown on the Pricing page; the price you see before you pay is the price you pay. Payment methods: cryptocurrency (the stablecoins USDT and USDC — see how to pay) and, where offered, bank card through a third-party payment provider. Card details are entered on the provider’s page and never reach us.

A cryptocurrency payment is credited when the transfer is confirmed on the blockchain. Send exactly the amount shown in your account: the cents identify your payment. Network and exchange fees are paid by the sender. An amount received above the price is credited to your AI budget; an amount below the price is not credited automatically — write to support and we will sort it out by hand.

The price shown is the total you pay to us. Taxes, duties and bank or exchange fees charged by your bank, your exchange or the authorities of your country are your responsibility. After payment you receive a confirmation by e-mail with the plan, the amount and the payment reference.

If something is wrong with a payment, please write to support@kawnaddin.com first — we resolve such cases quickly. A dispute opened with a bank for a payment that was delivered in full may lead to suspension of the account.

10. Delivery of the service

The services are digital; nothing is shipped. After a payment is confirmed the plan and the AI budget are activated automatically, usually within minutes (for cryptocurrency — after the network confirms the transfer). If the service is not active within 24 hours of the confirmation, write to support@kawnaddin.com with the payment reference: we will fix it or refund the payment.

11. Refunds and cancellation

Before buying, every registered user can see all features of the site and receives a free AI trial budget, so all payments are final and non-refundable once the service has been delivered (the plan is activated and the AI budget allocated). An unused balance is not refunded.

Exceptions: (a) a duplicate charge; (b) a service not delivered through our fault; (c) cases where a refund is expressly required by the law of your country. To claim, write to support@kawnaddin.com from your account e-mail within 30 days of the payment, with the payment reference. A refund is made to the original payment method; a cryptocurrency payment is returned in the same stablecoin, in the amount received less the network fee.

Cancellation. A plan paid in cryptocurrency simply ends at the end of its term and is never renewed automatically: there is nothing to cancel. A card subscription can be cancelled at any time in your account (“Subscription” tab) or by writing to support: this stops future renewals, the plan works until the end of the paid year and the paid year is not refunded. The full policy is on the Refund policy page.

12. Suspension and termination

We may suspend or close an account for breach of these Terms — automated data collection, sharing a paid plan, abuse of AI search, fraud or an unfounded payment dispute. If the account is closed because of such a breach, the unused term is not refunded. You can stop using the site at any time and ask us to delete your account (see the Privacy Policy); deleting an account ends access to the paid services, and the unused term is not refunded.

13. Disclaimers and limitation of liability

The site and the services are provided “as is”. We do not guarantee uninterrupted operation, the absence of errors, or that the answers of AI search or the calculations of the tracker are complete or correct. Nothing on the site is a fatwa or personal religious, medical or legal advice.

To the extent permitted by law, our total liability to you for any claim is limited to the amount you paid for the service in the 12 months before the claim, and we are not liable for indirect or consequential loss. Nothing in these Terms excludes liability that cannot be excluded by law or limits the rights you have as a consumer under the law of your country.

14. Disputes

If something goes wrong, please write to us first: we will try to resolve the matter within 30 days. This does not limit the rights you have under the mandatory consumer-protection law of your country.

15. Infringement notices and feedback

If you find a copy of our content published in breach of these Terms, or wish to obtain permission to use the materials, please contact us at legal@kawnaddin.com. The rights holder reserves the right to demand the removal of unlawfully used materials and to protect its rights by all lawful means.

Questions about payment, subscriptions and refunds: support@kawnaddin.com. All contact addresses are listed on the About & Contact page.

16. Changes to these Terms

These Terms may be updated. The current version is always available at kawnaddin.com/terms.html. The date of the latest change is shown in the heading. Material changes affect future purchases only; after a material change we will ask you to accept the new version the next time you sign in.
