Terms of service

These terms are the agreement between you and Tensflare for using Duct, Tensflare accounts and Duct’s paid plans. Please read them; if you don’t agree, don’t use the services.

Last updated: 8 October 2026

1. Who we are

The services are provided by Tensflare Ltd, a company registered in Nigeria, of Abuja, Federal Capital Territory, Nigeria (“Tensflare”, “we”, “us”). Legal notices to us: notices@tensflare.com.

If you use the services for an organisation, you confirm that you may accept these terms for it. “You” then means the organisation too. Organisations on Enterprise plans may have a separate written agreement, which takes priority over these terms where they differ.

2. The software and its licence

Duct’s source code is published under two licences: the app, library and CLI under the Apache License 2.0, and the team server features under the Elastic License 2.0 (see LICENSING.md in the repository). Those licences govern your use, copying and modification of the software itself; a team server’s features need a Team or Enterprise plan after a 30-day evaluation. These terms cover the services around it: the website, Tensflare accounts, paid plans, hosted features and support. The Duct name and logo are trademarks of Tensflare; the licence doesn’t grant rights to use them.

3. Accounts

• An account is optional. You need one only for paid features. You must be 18 or over to create one.
• Keep access to your email address and devices secure: whoever controls your email can sign in. Tell us at security@tensflare.com if you think your account has been misused.
• You can sign out from Duct’s Settings › Account. To sign out other devices or delete your account, write to privacy@tensflare.com.

4. Paid plans and billing

• What you get. Each plan includes the features described on the pricing page when you buy it. Plans marked “early access” are offered as they are, while we build them.
• Who you pay. Purchases may be processed by Dodo Payments as merchant of record: it sells you the plan as our reseller, collects payment and handles sales tax, and its buyer terms also apply. Local payment methods may be processed by Paystack or Kora.
• Renewal. Plans renew automatically at the end of each billing period (monthly or yearly) until you cancel. We will remind you before a yearly plan renews.
• Cancelling. You can cancel at any time; the plan then ends at the end of the period you paid for. Refunds are covered by our refund and cancellation policy, which includes a 14-day refund on your first purchase of a plan.
• Price changes. We will give you at least 30 days’ notice of a price increase, which applies from your next renewal. You can cancel before then.
• Taxes. Prices exclude taxes unless shown otherwise. Applicable taxes are added at checkout.
• Offline use. Paid features keep working offline for up to 30 days after Duct last confirmed your plan. After that they pause until Duct reconnects. Nothing is deleted.

5. Your documents and data

Your documents are yours. Duct processes them on your own computer or server, and we don’t receive or claim any rights in them. You are responsible for having the right to use the documents you add to Duct, and for keeping your own backups. How we handle personal data is set out in our privacy policy. For Team and Enterprise customers who need it, we offer a data processing agreement on request.

6. AI features

Ask (Labs) and similar features produce text with an AI model. That text can be wrong or incomplete. Duct shows the passages an answer was drawn from so you can check it. Check them before relying on an answer, especially for legal, financial, medical or other important decisions. AI output is not professional advice. If you use your own AI provider, your agreement with that provider governs what it does with the passages it receives.

7. Acceptable use

You must not use the services to:

• break the law or infringe anyone’s rights;
• try to get into accounts or systems you aren’t authorised to use, or interfere with the services, including by overloading them or getting around rate limits;
• resell or share account access or paid entitlements, except as your plan allows;
• misrepresent your plan, for example by tampering with entitlement tokens.

Security research done in good faith under our disclosure policy is welcome.

8. Developer API

When you run Duct’s developer API on your own infrastructure, you operate it and are responsible for your use of it and for your users’ data. Keep API keys secret, and use the scopes and collection limits to give each key only the access it needs.

9. Availability and changes

Duct’s local features don’t depend on our servers. For the online parts (accounts, entitlements, usage counts) we aim for high availability but can’t promise they will never be interrupted. We may change the services. If a change removes a significant part of a paid plan you are using, we will tell you in advance, and you may cancel and receive a pro-rata refund for the unused part of your billing period.

10. Warranties

We provide the services with reasonable skill and care. Apart from that, and from any rights you have by law that can’t be excluded, the services are provided “as is”, without other warranties. The open-source software itself comes with the warranty disclaimer in the Apache License 2.0.

If you are a consumer, nothing in these terms limits the rights you have under the consumer protection laws of the country where you live, for example the Federal Competition and Consumer Protection Act 2018 in Nigeria, the Consumer Protection Act 2012 in Kenya, the Consumer Protection Act 2008 and Electronic Communications and Transactions Act 2002 in South Africa, the consumer law of EU member states, and the Consumer Rights Act 2015 in the United Kingdom.

11. Liability

To the extent the law allows, Tensflare is not liable for indirect or consequential loss, or for loss of profits, revenue, data or goodwill. Our total liability for all claims arising from these terms in any 12-month period is limited to the greater of USD 100 and the amount you paid us in the 12 months before the claim.

Nothing in these terms limits liability that can’t be limited by law, such as liability for death or personal injury caused by negligence, or for fraud. For consumers in the EU and UK, we are also responsible for foreseeable loss caused by our breach of these terms.

12. Ending the agreement

You can stop using the services and cancel any plan at any time. We may suspend or close an account that seriously or repeatedly breaks these terms or creates a security risk. Where reasonable, we will warn you first and give you a chance to put things right. If we close your account without you being at fault, we will refund the unused part of any prepaid period. Ending the agreement doesn’t affect your use of the open-source software under its licence.

13. Disputes and governing law

If you have a problem, contact us first at notices@tensflare.com and we will try to resolve it within 60 days.

These terms are governed by the laws of the Federal Republic of Nigeria. Business customers agree that any dispute not resolved informally will be settled by arbitration under the Rules of the Lagos Court of Arbitration, with its seat in Lagos, Nigeria.

If you are a consumer, you also keep the protection of the mandatory laws of the country where you live, and you may bring proceedings in the courts there where your law gives you that right. Where your law allows it, disputes are resolved individually, not as part of a class action. Consumers in the EU can also use their national consumer dispute-resolution bodies.

14. General

• Changes to these terms. We will post changes here and update the date above. For material changes we will give account holders at least 30 days’ notice by email. If you don’t accept the change, you can cancel before it takes effect.
• If any part of these terms is found unenforceable, the rest still applies.
• We may transfer these terms to a company that takes over the services, if your rights are not reduced. You may not transfer them without our consent.
• These terms, the policies they link to and any order form are the whole agreement between us about the services.
