The plain version, in the order it matters.

Last updated 26 September 2026

Who you are agreeing with

These terms cover this website and the Madar OS application, both operated by Ahmed Yahya Al Kindi Enterprise, a sole proprietor establishment registered in Muscat, Oman (commercial registration 1399884), trading as TSB Labs. Contact: akenterprise.om@gmail.com.

Who takes your payment

Plans, trials and billing

• Madar OS is sold as a subscription: Launch OS, Founder OS and Business OS, billed monthly or yearly at the prices on our plans page, in US dollars. Enterprise is sold by written agreement.
• Self serve plans start with a 7 day free trial. A payment method is taken at the start; you are charged when the trial ends unless you cancel before then.
• After the trial, the plan renews automatically at the start of each billing period until you cancel. Prices are shown before tax; Paddle adds VAT or sales tax at checkout where the law requires it.
• Each plan includes an allowance of AI use. Use beyond it is sold as top ups at the price shown in the app before you buy; nothing extra is charged without your confirmation.
• If a price changes, we tell you by email at least 30 days before it applies to your next renewal, and you may cancel before then.

Cancelling and refunds

You can cancel at any time from your account or by emailing us. Cancelling stops the next renewal, and you keep access until the end of the period already paid for. Refunds follow our refund policy: any payment can be refunded in full on request within 14 days of the charge.

Using the application

You agree to:

• connect only accounts you own or are authorised to administer
• keep your credentials to yourself, and tell us promptly if they are exposed
• not use it to send unlawful, deceptive or unsolicited bulk messages
• not attempt to reverse engineer, resell or sublicense it without written permission

You remain responsible for what is sent from your accounts. Madar prepares the work and stops at anything irreversible, such as a message, a booking, a payment or a deletion, so a person is always the one who approves it.

What we own, and what you own

The software, its design and its documentation remain the property of Ahmed Yahya Al Kindi Enterprise. Your business data remains yours. We claim no ownership over your content and we do not use it to build a product for anyone else. You can export it at any time and ask us to delete it when you leave.

The demonstration pages

The walkthrough and the demo workspace on this site run a fictional company. Every company, person, client and number in them is invented; do not rely on any figure shown there as a statement of performance.

Availability

We work to keep Madar OS available and improving, and features may change. Where the service depends on a third party, such as an AI model provider, Google, Meta or an email provider, an outage there is outside our control; when Claude is at a usage limit, Madar says so and holds actions until it is back.

Liability

To the extent Omani law allows, our total liability arising from the site or the application is limited to the fees you paid in the three months before the claim. We are not liable for indirect or consequential loss, including lost profits or lost business opportunities.

Ending it

You may stop using the service at any time by cancelling your subscription, and revoke Madar's access to a Google account at myaccount.google.com/permissions. We may suspend access for a material breach of these terms, and will say why.

Governing law

These terms are governed by the laws of the Sultanate of Oman, and disputes fall to the courts of Muscat. Nothing here removes rights you have as a consumer where you live.

Changes

If these terms change materially, the date at the top changes with them, and subscribers are told by email before the change takes effect.
