Who you are agreeing with

These terms cover this website, the Madar OS application and the Madar POS application, all operated by Ahmed Yahya Al Kindi Enterprise, a sole proprietor establishment registered in Muscat, Oman (commercial registration 1399884), trading as TSB Labs. Contact: hello@madar-os.com. Help with the product: support@madar-os.com. Payments and refunds: billing@madar-os.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.
• Madar POS is sold as a subscription: Grocery and Supermarket, each with one branch included and more branches added by number, billed monthly or yearly at the prices on our Madar POS page, in US dollars. Hypermarket is sold by written quote. In these terms, a plan includes a Madar POS package.
• 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. We email you two days before the first charge.
• During the trial, AI use is capped at USD 20, about 2,000 credits. Your plan's full monthly allowance starts with the first payment, less what the trial used.
• 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 a monthly allowance of AI use, in credits. It renews each month, and what is left of it does not carry over. 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. Credits you buy do not expire at the end of the month: they are spent only after the month's included ones, and stay with your workspace while it is kept. Once a subscription ends, Madar's assistant stops answering, so they can be spent again only after you renew, and they end with the workspace when it is deleted.
• 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 with Manage or cancel your subscription on Plans and usage in the app, from the link in your Paddle receipt or in the reminder we send before your trial ends, or by emailing billing@madar-os.com. 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
• follow Anthropic's Usage Policy, because Madar's answers are written by Anthropic's Claude models
• 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.

Answers are written by AI, and AI can be wrong. Madar can misread a document, get a number wrong or state something with more confidence than it deserves. Check anything that matters, such as figures, legal points, prices and dates, before you rely on it or approve 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. The owner can download it at any time in Settings, with Download my data, and ask for its deletion there with Delete my workspace. We delete the workspace within 30 days of your request, and its backup copies expire 30 days after that. You can also write to privacy@madar-os.com for either, and we do it within 30 days.

Your customers' data

For the people in your records, such as your customers, suppliers and staff, you decide what is kept and why. We process that data only to run Madar for you, on your instructions, and never for our own purposes. We keep it confidential, and within our business only the people who run our servers can reach it. We look inside your workspace only to keep it running, to restore it, when you ask us to, or when an authority requires it by a written order, and we tell you unless the order forbids it. The companies that handle data for us are listed in our privacy policy; we tell you by email at least 14 days before we add one, so you can object or leave. We tell you within 24 hours of learning of a breach that touches your data, and we help you answer requests from the people in your records. When you leave, you can first download everything in Settings. After your package ends, your workspace is deleted at least 60 days later, as our privacy policy sets out, after we email you 14 days and 3 days before and a person at Madar confirms it. If you ask us to delete it, we do so within 30 days of your request. Either way, its backup copies expire 30 days after the deletion, unless the law requires us to keep it.

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 and Madar POS available and improving, and features may change. Anything our plans page marks as rolling out, or the Madar POS page lists as on the way, is not part of the service until it is live. Where the service depends on a third party, such as Anthropic, Oracle, Paddle or an email provider, an outage there is outside our control; when Madar cannot reach its AI model, it says so and takes no action until it can.

Liability

To the extent Omani law allows, our total liability arising from the site or the applications 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 remove any tool you connected from Tools and mail. Your package ends when a subscription paid through Paddle ends, or, for a package paid by invoice, at the end of the last day it was paid for; when both are known, the days that follow count from the later end, so a period paid for is never cut short. When a subscription paid through Paddle ends, Madar's assistant stops answering. For 30 days after the end Madar POS keeps selling. Then Madar POS is read only for 30 days: nothing new can be sold or changed, though a tax invoice can still be given for a past sale and a sale Madar refused can still be settled, and a sale made without the internet before that day is still recorded within the three days Madar takes any offline sale for. Then your workspace, Madar OS or Madar POS, is deleted, at least 60 days after the end: we email you 14 days and 3 days before, and a person at Madar confirms it. Until then you can see and download everything in it, and if you renew before then, everything is kept. If you ever gave Madar access to a Google account, you can revoke it 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.
