Terms of Service

Tennsa (Pty) Ltd | Registration 2025/913829/07 | Last updated 30 September 2026

These terms govern your use of Tennsa OS. By creating an account you agree to them. If you are signing up on behalf of a business, you confirm you are authorised to bind that business, and "you" in these terms means the business.

We have written these in plain language. Where a term has legal weight, we have tried to say so.

1. What Tennsa is

Tennsa OS connects the business systems you already use - accounting, inventory, payments, commerce, CRM, email and team chat - reads them together, and tells you what needs attention. It delivers a daily briefing by email, answers questions about your business from your own records, and produces reports.

Tennsa is read-only. It never writes to, changes, or deletes anything in a system you connect. This is enforced in our code and, where the connected system supports it, by the permissions of the account you connect.

Tennsa reports what your data shows. It does not give advice. The findings, figures and answers Tennsa produces are computed from your connected records and presented for your information. They are not financial, legal, tax or accounting advice, and you should not treat them as a substitute for professional judgement.

2. Your account

You need an account to use Tennsa. You are responsible for keeping your password confidential and for everything done under your account.

You may give other people in your business a seat on your account. Your plan includes one seat, and you can add more. You are responsible for the people you add, and you can remove them at any time.

You must be eighteen or older to create an account.

3. Connecting your systems

When you connect a system to Tennsa, you authorise us to read from it on your behalf. You confirm that:

• You are entitled to grant that access.
• You have the right to share the information in that system with us, including any personal information about your customers, suppliers and staff that it contains.
• You will tell the people whose information you share with us as your own obligations under POPIA require.

You can disconnect any system at any time. When you do, we delete what we hold from that source, and where the provider supports it we revoke our access at the provider. Some systems are connected with a key you issued to us, which only you can cancel at that system - we delete our copy, and you should cancel the key.

Some systems require a licence from their vendor before a third party can read from them. For example, IQ Retail charges a monthly fee per branch for API access, and Sage Evolution requires a connector licence. Where a vendor fee applies, it is payable by you to the vendor, and Tennsa will tell you clearly before you connect.

4. Files you upload

You may upload files to your Tennsa workspace. You confirm you are entitled to share what they contain. We store them for the life of your account; nothing removes an uploaded file on a timer. Where the page you uploaded from offers a delete you can remove the file yourself, and deleting your account removes every file. We use them only to answer your questions and build your briefing.

5. Connecting an AI assistant

Tennsa can connect to AI assistants you already use, such as Claude, ChatGPT or Gemini. If you choose to do this:

• You are instructing us to share your Tennsa data with that provider when their assistant asks for it on your behalf.
• That provider handles the data under their own terms, not ours.
• You can revoke the connection at any time.
• Information derived from your email is never shared through this channel.

6. Data protection

How we handle personal information is set out in our Privacy Policy, which forms part of these terms.

Under POPIA, you are the responsible party for the personal information in the systems you connect, and Tennsa is your operator. We process that information only as you instruct, we keep it secure, and we tell you if anything goes wrong. Our Data Processing Agreement, available on request and forming part of these terms for business customers, sets out the operator terms that section 21 of POPIA requires.

7. Subscription and payment

Trial. New accounts receive a fourteen-day free trial with full access. No card is required to start.

Subscription. After the trial, Tennsa OS is R2,750 per month excluding VAT, or R28,050 per year, for the plan as you configured it. Extra seats are R450 each per month. Connections to ERP systems (IQ Retail, Sage 200 Evolution, SYSPRO) are priced per branch with a one-time setup fee per system, as set out on tennsa.com/pricing. Prices are shown on tennsa.com/pricing and may change with thirty days' notice; changes do not affect a period you have already paid for.

Larger organisations. If your business needs terms we do not publish, contact us and we will discuss them with you.

Payment is by card through our payment provider, Paystack. All prices are quoted and all payments are taken in South African rand (ZAR). Subscriptions renew automatically until cancelled. If a payment fails, we will tell you and give you a reasonable period to fix it before restricting access.

Cancellation. You can cancel at any time from your account settings. Cancellation takes effect at the end of the current billing period. We do not refund partial periods.

Founding customers. We may agree different terms with early customers in writing. Where we have, those terms apply.

8. What you may not do

You may not:

• Use Tennsa for anything unlawful.
• Connect a system you are not entitled to connect, or upload information you are not entitled to share.
• Attempt to access another customer's account or data.
• Reverse engineer, copy or resell the service.
• Use Tennsa to build a competing product.
• Interfere with the service or attempt to circumvent its security.

If you do, we may suspend or terminate your account.

9. What we promise, and what we do not

We will:

• Keep the service running with reasonable care and skill.
• Keep your data secure as described in our Privacy Policy.
• Tell you before we change these terms or our prices.
• Be honest about what the service can and cannot see. When Tennsa cannot reach one of your systems, it says so rather than guessing.

We do not promise:

• That the service will be uninterrupted or error-free. It depends on the systems you connect, and those systems are outside our control.
• That any finding is complete or correct. Tennsa reads what your systems provide; if a system provides wrong information, Tennsa will report it faithfully.
• Any particular business outcome.

10. Liability

To the extent the law allows:

• Tennsa is not liable for any loss arising from decisions you make based on what the service shows you. The service provides information; the decisions are yours.
• Tennsa is not liable for indirect, consequential or special losses, including loss of profit or business.
• Tennsa's total liability to you in any twelve-month period is limited to the amount you paid us in that period.

Nothing in these terms limits liability that cannot be limited by law, including under the Consumer Protection Act where it applies.

11. Termination

By you: cancel from your account settings at any time. You can also delete your account entirely, which removes all your data as described in the Privacy Policy.

By us: we may suspend or terminate your account if you breach these terms, if required by law, or if we discontinue the service. We will give reasonable notice except where the breach is serious or the law requires otherwise.

On termination: your access ends, and your data is deleted as described in the Privacy Policy unless you ask us to keep it for a reasonable period to export it.

12. Intellectual property

Tennsa OS, its software, design and content belong to Tennsa (Pty) Ltd. Your data belongs to you. By using the service you grant us only the licence we need to provide it to you.

13. Changes

We may update these terms. We will tell you by email at least thirty days before a material change takes effect. If you do not agree, you can cancel before the change applies.

14. General

These terms are governed by the laws of South Africa. Disputes will be heard in the courts of the Western Cape.

If any part of these terms is found unenforceable, the rest continue to apply.

These terms, together with the Privacy Policy (which includes our Cookie Policy) and any Data Processing Agreement, are the whole agreement between us.
