Terms of Use

Last updated 4 November 2026

These terms apply when you use this website (heatsigofficial.com), order SORVA, or use the HeatSig app, including the Pilot Trial. Please read them, especially “What SORVA is, and what it isn’t”.

HeatSig Pte Ltd (“HeatSig”, “we”, “us”) is a company registered in Singapore, at #03-02, 531 Upper Cross Street, Singapore 050531.

Nothing in these terms takes away the rights you have under the consumer laws of the country where you live.

What SORVA is, and what it isn’t

SORVA is a ceiling light with HeatSig thermal sensing. It can notice when someone stops moving (after a fall or a faint, for example) or a fire in the room, and alert the people you choose: first by a notification in the HeatSig app or on Telegram, and then by a call. It’s an extra pair of eyes for a family, not a replacement for care.

  • It is not a medical device. It doesn’t diagnose, treat or monitor any medical condition.
  • It is not an emergency service. It doesn’t call an ambulance, the fire service or the police. In an emergency, call your local emergency number.
  • It is not a smoke alarm. Keep the smoke alarms your home or local rules require.
  • It can miss events or alert when nothing is wrong. For example, when the power, Wi-Fi or internet is down, when notifications are turned off on your phone, when someone is outside the sensor’s view or blocked by furniture, when several people are in the room, or when there are other strong heat sources nearby.
  • Alerts only help if someone sees them. Make sure at least one person you share the light with can respond.
  • It doesn’t replace supervision or professional care where a person needs it.

Using this website

  • You may use the site for your own information and to contact us or order from us.
  • Don’t misuse it, for example by sending spam or harmful code, or by trying to get into parts of it you’re not meant to.
  • We try to keep product details, prices and dates accurate. Specifications, availability and shipping dates may change before you order.
  • The site’s text, photos, designs and logos belong to HeatSig or the people who licensed them to us. Please don’t copy them without permission.
  • Links to other websites are for convenience. We’re not responsible for their content.

Ordering

  • Payment: after you send the order form, you pay by card on a secure Stripe checkout page. The checkout page shows the amount before you pay. Each payment covers one SORVA; to order more, place another order or contact us.
  • Invoice: we email you an invoice with the amount paid and your delivery details.
  • When it becomes an order: your order is confirmed once your payment is received. Your SORVA is then reserved for an upcoming shipment.
  • Price: SGD 800 per light. Shipping, import duties and local taxes not included in the checkout amount are shown on your invoice or paid on delivery, as your invoice explains.
  • Shipping date: SORVA is expected to ship in Fall 2026, worldwide. This is an estimate. If the date moves, we’ll tell you, and you can cancel for a full refund of anything you’ve paid.
  • Cancelling: you can cancel at any time before your SORVA ships, for a full refund of anything you’ve paid.
  • Limited quantities: quantities are limited until public release.
  • When we may decline or cancel: we may decline or cancel an order, for example if we can’t deliver to your country or there was an obvious pricing error. If we do, we refund anything you’ve paid in full.

Delivery, duties and taxes

  • We ship to the address on your invoice. Check it carefully.
  • Unless your invoice says otherwise, import duties, customs fees and local taxes in your country are paid by you.
  • Before you order, check the specifications to make sure SORVA suits your home’s electricity supply and ceiling point. If you’re not sure, ask us on WhatsApp.
  • SORVA is your responsibility once it has been delivered.

Installation and safety

  • SORVA goes on a standard ceiling point and must be installed as the manual describes.
  • Install SORVA only where the manual says it is suitable. Don’t fit it in a bathroom or another wet area unless the manual says you can.
  • In many countries, connecting a light to the mains must be done by a qualified electrician. Follow your local rules.
  • Switch off the power before installing.
  • Don’t open, modify or repair the light yourself.
  • SORVA needs a working Wi-Fi connection and the HeatSig app to send alerts.

Returns and refunds

  • European Union and United Kingdom: you can cancel within 14 days after delivery without giving a reason. Tell us by email within that time and send SORVA back within 14 days after that. We refund what you paid, including standard delivery, within 14 days of getting it back. You pay the return postage unless SORVA is faulty or we sent the wrong item. You may have to pay for any loss in value caused by handling SORVA more than needed to try it.
  • Everywhere else: if you want to return an unused SORVA in its box, contact us within 14 days after delivery. We’ll explain how to send it back and refund the price once we receive it.
  • Faulty light: if SORVA is faulty, see “Warranty”. Your rights under local consumer law always apply.

Warranty

  • We guarantee SORVA against defects in materials and workmanship for the period shown on the warranty card in the box, counted from delivery.
  • During that period we repair or replace a faulty light. If we can’t, we refund it.
  • It doesn’t cover damage from installation that doesn’t follow the manual, misuse, accidents, power surges, or repairs by anyone else.
  • To claim, email us with your order number and a description of the problem.
  • This warranty is in addition to your rights under consumer law. In the EU and UK, for example, you have a legal guarantee of at least 2 years for goods that don’t match their description or are faulty.

The HeatSig app and your account

  • You must be 18 or older to create an account.
  • Give accurate details and keep your login to yourself. You’re responsible for activity on your account.
  • Share a light only with people you trust to receive its alerts.
  • Keep the app’s notifications switched on and the app up to date. If you choose Telegram or calls, keep those working too.
  • We may update the app and SORVA’s software to improve security and features. Some updates install automatically.
  • The service depends on the internet and on services run by others, such as app stores, Telegram and phone networks. We work to keep it running, but can’t promise it will never be interrupted.
  • You can close your account at any time.
  • We may suspend an account that breaks these terms or puts others at risk. Unless there’s a safety or legal reason not to, we’ll tell you first.

Watching over someone else

If you install SORVA where someone else lives:

  • Tell them what it does and who receives its alerts, and get their agreement before you switch it on.
  • If they can’t agree for themselves, get the agreement of the person legally able to decide for them.
  • Follow the laws on monitoring and privacy where the light is installed.
  • Don’t use SORVA to watch anyone without their knowledge, for example a tenant or a guest.

Things you must not do

  • Use SORVA or the app for anything unlawful.
  • Tamper with SORVA or the app, copy, or reverse-engineer them, except where the law allows it.
  • Try to get into our systems, or another person’s account or home.
  • Interfere with how the service works for others.

Intellectual property

  • HeatSig™, SORVA and their logos are our trademarks. SORVA’s technology is protected by 6 patents, including US Patent No. 11,246,205 B1.
  • We give you a personal, non-transferable right to use the app with your SORVA lights.
  • The photos, films, text and design of this website and the app are ours or used under licence. Please don’t copy or reuse them without our written permission.
  • Everything else stays ours or our licensors’.

Our responsibility to you

  • What we never limit: nothing in these terms limits our liability for death or personal injury caused by our negligence, for fraud, or for anything else the law doesn’t allow us to limit.
  • Indirect losses: apart from that, and as far as the law allows, we’re not liable for loss of profit or business, or for losses we couldn’t reasonably have foreseen.
  • Missed and false alerts: because SORVA can miss events or alert by mistake (see “What SORVA is, and what it isn’t”), we’re not liable for harm that a missed or false alert didn’t cause and couldn’t have prevented.
  • Our maximum liability: our total liability for any claim is limited to the amount you paid for the SORVA lights concerned.
  • Buildings: projects for buildings (Light Revolution) are covered by a separate written agreement.

Privacy

How we handle personal data is explained in our privacy policy.

Changes to these terms

We may update these terms, for example when we add features or the law changes. The date at the top shows the latest version. The terms that applied when you placed an order apply to that order. If a change affects how you use the app, we’ll tell you in advance.

Law and disputes

  • Talk to us first: if something goes wrong, please contact us. Most problems can be sorted out quickly.
  • Governing law: these terms are governed by the laws of Singapore, and the courts of Singapore can hear disputes.
  • Consumers abroad: if you’re a consumer living elsewhere, you keep the protection of your own country’s mandatory laws, and you can bring a claim in the courts where you live.
