Terms & conditions
Last updated: 14 October 2026
These terms apply to every purchase you make on this website (airtime.diy). By placing an order you agree to them. They sit alongside your rights under South African law, including the Consumer Protection Act 68 of 2008 (CPA) and the Electronic Communications and Transactions Act 25 of 2002 (ECTA), which these terms do not limit.
1. Who we are
AirTime is a South African seller of open-source time-signal transmitter hardware for radio-controlled watches and clocks. We dispatch from Menlo Park, Pretoria, 0081, South Africa. To reach us, use the contact form. Please quote your order reference in any message about an order.
2. Products
We sell the AirTime transmitter board and related accessories. The board is a hobbyist and educational device designed to be attached to a Raspberry Pi and used with the open-source AirTime software. Product descriptions, specifications and photographs are as accurate as we can make them, but colours and minor details may differ slightly. Stock is limited and shown on the product page.
You are responsible for using the product lawfully. Low-power time-signal transmission is regulated in some countries. Check the rules that apply where you will use it before buying.
3. Prices and currency
All prices are in South African rand (ZAR) and include any VAT that applies. If you browse from outside South Africa we may show an approximate amount in your own currency for convenience, but you are always charged in rand, and your bank or card issuer may apply its own exchange rate and fees. Shipping is added at checkout based on the FedEx rate for your address, and is shown before you pay. We may correct pricing errors and will tell you before dispatch if an order is affected, in which case you may cancel for a full refund.
4. Ordering and payment
Your order is placed when you complete payment and accepted when we confirm it by email. Payments are processed by our payment provider, Stitch, who accept cards, instant EFT and other methods they offer. Your card or bank details are entered on the provider's secure page and are never seen or stored by us. We may cancel and refund an order if we cannot fulfil it, for example because stock has run out or we suspect fraud.
5. Delivery
Orders ship from South Africa by FedEx to the address you enter at checkout. The delivery options and cost are shown before you pay. We aim to dispatch within a few business days of payment, and transit time depends on the FedEx service you choose and your destination. Delivery dates are estimates, not guarantees. We email you FedEx tracking details once your order ships.
Please make sure your delivery address and phone number are correct. If a parcel is returned to us because of an incorrect address or because it was not collected, we may charge the shipping costs to send it again.
International orders. Customs duties, import VAT and local taxes may be payable on delivery and are your responsibility unless we have shown them at checkout. We have no control over customs clearance delays.
Risk in the goods passes to you when they are delivered to the address you gave. Ownership passes to you when we have received full payment.
6. Returns, cancellations and refunds
Our Refund and Cancellation Policy forms part of these terms.
7. Warranty and faulty goods
Goods must be of good quality and fit for their purpose. If an item arrives faulty or damaged, or is not what you ordered, you are entitled to the remedies in the CPA, including repair, replacement or refund. See the Refund and Cancellation Policy for how to claim. This does not cover damage caused by misuse, modification, incorrect wiring or power, or normal wear.
8. Limitation of liability
To the extent the law allows, we are not liable for indirect or consequential loss, or for loss arising from your use of the product in breach of local radio regulations. Nothing in these terms excludes liability that cannot lawfully be excluded, including liability for our gross negligence or for goods that do not meet the standards of the CPA. Our total liability for any order is limited to the amount you paid for it.
9. Privacy
We collect your name, email address, phone number and delivery address to process and ship your order. We share them only with the providers who need them to complete it: our payment provider and FedEx, and our hosting and email providers. We keep order records as long as the law requires, and we do not sell your personal information. You may ask to see, correct or delete your information through the contact form. We handle personal information in line with the Protection of Personal Information Act 4 of 2013 (POPIA).
10. Open-source software
The AirTime software is open source under the AGPL-3.0 licence, available on GitHub. These terms cover the sale of hardware, not the licence of the software, which is provided as described in its own licence.
11. Changes to these terms
We may update these terms from time to time. The terms in force when you place an order apply to that order.
12. Governing law and disputes
These terms are governed by the laws of the Republic of South Africa. If you have a complaint, please contact us first so we can try to resolve it. You may also approach the National Consumer Commission or the consumer court in your province.
