Terms of use

Version 2026-11-01. Last updated 1 November 2026.

These terms are an agreement between you and RizMade Ltd, a company registered in England and Wales (company number 17529077, registered office 128 City Road, London, EC1V 2NX) ("RizMade", "we", "us"). They cover IonVolt, the app for your home battery, solar and EV charger; IonVolt Bridge; our servers; and this website (together, "IonVolt"). You accept them when you create an account, and again in the app whenever we change them. If you don't accept them, please don't use IonVolt.

The short version

• IonVolt is an independent app. It isn't made, endorsed or supported by Duracell, FoxESS, Hypervolt or any other maker or supplier.
• Changes you make in IonVolt, and automations you set up, are sent to your real equipment. You choose them, and you're responsible for them. Follow your installer's and the maker's guidance.
• Readings, forecasts, savings and prices are estimates. IonVolt is provided as it is and may not always be available.
• IonVolt isn't a safety device. Don't rely on it where health or safety depends on power, such as medical equipment in a power cut.
• You must be 18 or over and allowed to control the equipment you connect.

The short version doesn't replace the full terms below.

1. Who can use IonVolt

You must be 18 or over and live in the United Kingdom. You may only connect an inverter, battery, EV charger or energy supplier account that you own or have the owner's permission to use and control. If you add someone else's account, or use IonVolt for a business, you confirm you have their permission. You're responsible for the information you give being accurate, including your tariff, battery size and whether a backup circuit is fitted.

2. The app's licence

We give you a personal, non-transferable, non-exclusive licence to use the IonVolt app on devices you own or control, for your own home. If you get IonVolt from Apple's App Store, Apple's Licensed Application End User License Agreement also applies. If you get it from Google Play, Google Play's terms of service also apply. These terms add to the store's terms. Where they disagree, the store's terms win. Apple and Google aren't responsible for IonVolt or for supporting it.

IonVolt, its design, code, text and graphics, and the IonVolt and RizMade names and marks belong to RizMade. Except where the law allows it, you may not copy, change, reverse engineer, decompile or disassemble the app, or build a product from it.

3. IonVolt Bridge

IonVolt Bridge (the software for a Raspberry Pi or other computer at home, its installer and the ready-made SD card) belongs to us and isn't open source. It comes with its own licence, summarised here. The full text is in the file LICENSE installed with it.

• You may download, install and run it only through the IonVolt app or our server, only on computers you own or control, and only to connect your own home energy system to IonVolt. You may only do this while you have an IonVolt account. Each download is linked to the account that asked for it (see the privacy policy).
• You may not copy it except to install and run it as allowed, plus one backup. You may not distribute, publish, share, sell, rent or lend it, or a link that downloads it. You may not modify it or make works based on it. You may not reverse engineer, decompile or disassemble it, except where the law allows you to whatever these terms say.
• You're responsible for the computer it runs on, your home network and its security.
• The licence ends if you break it or close your IonVolt account. You must then stop using it and delete your copies.

4. Your account

Keep your sign-in details to yourself. You're responsible for anything done with your account, including changes it sends to your equipment. Tell us straight away at hello@ionvolt.app if you think someone else has used it. You can delete your account at any time in the app, and we delete what we hold for it as the privacy policy describes. See how to delete your account.

5. Your inverter, battery, charger and supplier

IonVolt connects to your inverter, battery, EV charger and energy supplier by signing in to your own accounts with them, by using their published services, or through IonVolt Bridge on your home network. Those companies' own terms still apply to your accounts and equipment. We don't control their services. IonVolt can only do what their services allow, and features can change or stop working, without notice, if those services change, limit access or stop.

IonVolt isn't made, endorsed, approved or supported by any of those companies. Their names are used only to say what IonVolt works with. Using IonVolt may not be covered by your equipment's warranty or your installer's support, and it could affect them. Check with them if this matters to you.

6. Changing settings and automations

IonVolt changes your equipment only after you turn on Allow changes. It then changes it only when you ask, or when an automation, Smart charging, Free Hours or another feature that you've set up acts for you. By turning these on, you authorise IonVolt to send those changes to your equipment on your behalf, including while you're away from the app. You can turn them off at any time.

You're responsible for choosing settings that are right and safe for your equipment, your home, your tariff and the people in it. If you're not sure, ask your installer before changing anything. Never use IonVolt to change settings that only a qualified installer should change. Don't use it in place of electrical work, inspection or maintenance by a qualified person.

IonVolt reads each change back where the maker's service allows and tells you if a value didn't stick. Changes can still be delayed, fail or be undone by the maker's service, your equipment or another app. Check that important settings are as you want them, especially before a power cut, a long absence or a cold spell.

7. Safety, alerts and backup power

IonVolt is not a safety device and is not a monitoring or alarm service. Your equipment's own protections stay in charge. Alerts, including power cut, backup circuit, low battery, connection and car-charging alerts, depend on your phone, your internet connection, push services and other companies' services. They may arrive late or not at all. Don't rely on IonVolt, its alerts or a backup circuit for anything where health, safety or serious loss depends on power, such as medical or life-support equipment, refrigerated medicines or sump pumps. Make other arrangements for these.

Not every installation has a backup circuit (Duracell calls it Backup Output). Whether yours has one, and what it powers, depends on how it was installed. Telling IonVolt whether one is fitted only changes what the app shows. It doesn't change your installation.

8. Readings, forecasts and savings

Readings come from your equipment and other companies' services and may be delayed, missing or wrong. Smart charging, Free Hours, forecasts, carbon figures and the savings, prices and earnings IonVolt shows are estimates. They're worked out from your tariff, weather and solar forecasts and your past use. Real prices, weather and use differ, so your bills and earnings may differ too. Your supplier's bill is always the correct record. Don't make financial decisions based on IonVolt alone.

9. Subscriptions and the free trial

Live data, history, the 3D house and safety alerts are free. Pro, Pro Plus and Smart charging are subscriptions. You buy them in the app and they're charged to your Apple Account or Google account. They renew automatically unless you cancel at least 24 hours before the end of the current period. You can manage or cancel them in your account settings. New subscribers are offered 2 weeks free. If you don't cancel during it, the subscription starts when it ends. Apple or Google handle refunds under their own rules. Current prices are on our pricing page and in the app. We may change prices or what each plan includes. A price change applies from your next renewal after we've told you and you've had the chance to cancel, as Apple's and Google's rules require.

Refer a friend

Every IonVolt account has a referral code and link in Settings › Refer a friend. "Give a month, get a month":

• Your friend gets one month of IonVolt Pro free when they use your code or link in the app. It's for new accounts only: within 30 days of making the account, before they've ever paid for IonVolt, and one code per account. They can still start the store's free trial afterwards.
• You get one free month of your own plan once your friend has paid for 3 months. Free trials, free months and refunded payments don't count, and if your friend leaves before they've paid for 3 months, there's no free month for either of you after theirs. A yearly payment counts one month when it's paid and one more for each month that passes.
• How you get it. On Google Play we move your next payment back a month. On the App Store you claim it in the app as a free month offer. Without a store subscription, we add a month of your plan to your account. You can earn up to 12 free months in any 12 months.
• Fair play. You can't use your own code, a code from someone on the same phone, or more than one code. There's no cash value and free months can't be exchanged. We may cancel a referral or a free month that breaks these rules, and we may change or end the scheme for new referrals at any time.

Installers, creators and group admins who recommend IonVolt for commission do so under the separate partner terms.

10. Fair use

Don't misuse IonVolt. In particular, you must not:

• try to reach other people's accounts or equipment;
• interfere with our servers or the services we connect to, or put too much load on them;
• scrape our servers or use automated access other than the app and IonVolt Bridge;
• share your IonVolt Bridge download links or commands;
• use IonVolt to break the law or anyone else's terms.

We may limit, suspend or close an account that breaks these terms or puts other people, equipment or our service at risk. Where it's reasonable to, we'll tell you first.

11. Changes to IonVolt and availability

We keep improving IonVolt and may add, change or remove features. If a change takes away something important that you pay for, you can cancel your subscription. IonVolt depends on our servers, your internet connection and other companies' services. We don't promise it will always be available, work without interruption or be free of errors. We may pause it for maintenance, security or reasons outside our control.

12. Our responsibility to you

If you're a consumer, you have legal rights that these terms don't affect. This includes your rights under the Consumer Rights Act 2015 that digital content is as described, fit for purpose and of satisfactory quality. Citizens Advice can tell you more.

Nothing in these terms limits or excludes our liability for death or personal injury caused by our negligence, for fraud or fraudulent misrepresentation, or for anything else that can't be limited or excluded by law.

Apart from that, and as far as the law allows:

• We're only responsible for loss or damage that was a foreseeable result of our breaking these terms or failing to use reasonable care and skill. We're not responsible for loss that wasn't foreseeable when you accepted these terms.
• We're not responsible for loss or damage caused by:
  • settings you choose or automations you set up;
  • information you give us that isn't accurate;
  • your equipment, its installation, maintenance or protections;
  • your installer, maker, supplier or their services;
  • your phone, computer, home network or internet connection;
  • power cuts, network outages, or events outside our reasonable control.
• IonVolt is for domestic and private use. We're not responsible to you for business losses, including lost profit, revenue, contracts or business opportunity.
• If digital content we supply damages your device or other digital content because we didn't use reasonable care and skill, we'll repair the damage or pay you fair compensation, as the law requires.
• Otherwise, our total liability to you for all claims connected with IonVolt is limited to the greater of £100 and what you paid us for IonVolt in the 12 months before the event that led to the claim.

Each of these limits applies separately. If a court finds one of them unenforceable, the others still apply.

13. Claims from other people

If you connect equipment or accounts that you don't own or aren't allowed to control, or you use IonVolt in breach of these terms or the law, you're responsible for the losses and reasonable costs this causes us. This includes claims made against us by the owner of that equipment or account. This doesn't apply to anything that is our fault.

14. Ending this agreement

You can stop using IonVolt and delete your account at any time. Deleting your account doesn't cancel a subscription, so cancel that with Apple or Google too. We may end this agreement or close your account if you seriously or repeatedly break these terms. We may also do so if we stop offering IonVolt, in which case we'll give you reasonable notice where we can. Sections 3 (as to deleting copies of IonVolt Bridge), 12, 13 and 16 continue after the agreement ends.

15. Changes to these terms

We may update these terms, for example when IonVolt, the law or the services we connect to change. Each version has a date-based version number, shown at the top. When we publish a new version, the app asks you to read and accept it before you carry on. We keep a record of which version your account accepted and when. If you don't accept a new version, you can delete your account. Any subscription stays yours to cancel with Apple or Google.

16. General

• These terms, the store terms in section 2, the IonVolt Bridge licence and our privacy policy are the whole agreement between you and us about IonVolt.
• If a court finds part of these terms unenforceable, the rest still applies.
• If we don't enforce a term straight away, we can still enforce it later.
• We may transfer this agreement to another company that takes over IonVolt. Your rights won't be reduced and we'll tell you if this happens. You may not transfer it without our agreement.
• Apart from Apple and Google as set out in their own terms, nobody else has rights under this agreement.
• We're not responsible for delays or failures caused by events outside our reasonable control.

17. Law and complaints

If you have a problem, please email us first at hello@ionvolt.app. We'll try to sort it out quickly. These terms are governed by the law of England and Wales, and the courts of England and Wales can hear disputes. If you live in Scotland or Northern Ireland, you can also bring a claim in your own country's courts.
