Last updated: 13 November 2026
These terms are an agreement between you and Techful Limited, trading as Tankful ("Tankful", "we", "us"). They cover your use of the Tankful website, web app and tank level monitors (together, the "service"). By creating an account or using the service, you agree to them.
If you use the service for a business or other organisation, you agree to these terms on its behalf and confirm you have the authority to do so.
1. About us
Tankful is operated by Techful Limited, a New Zealand company (NZBN 9429048987356), of 12 Kagan Ave, Mangawhai 0505.
You can contact us at support@tankful.nz.
2. The pilot
Tankful is in a testing phase. During the pilot:
- the service is provided free of charge;
- features may change, break or be removed, and the service may be unavailable from time to time;
- we may ask you for feedback, which we can use freely to improve Tankful; and
- either of us may end your participation at any time (see section 11).
3. Your account
- You must be at least 18 years old to create an account.
- Give us accurate information and keep it up to date, including an email address you can receive alerts at.
- Keep your password secret. You are responsible for what happens under your account.
- Tell us straight away if you think someone else has accessed your account.
4. Sites and members
A site is a property with one or more tanks. A site's owner can invite other people to it.
- If you invite someone to a site, they will be able to see that site's details, including its address, location and tank levels. Only invite people you are happy to share these with.
- Site owners are responsible for who has access to their site and for removing members who should no longer have access.
- You must have the right to install a monitor on, and share information about, any tank and property you add.
5. Tankful devices
During the pilot we lend you the Tankful device.
- The device stays the property of Techful Limited. You must not sell it, give it away or use it as security.
- Install and use it as we instruct, and take reasonable care of it.
- Do not open, modify or reverse engineer the device or its firmware, or use it with any service other than Tankful.
- We may update the device's firmware remotely.
- If we ask for the device back, or your participation in the pilot ends, return it to us within 30 days. We will tell you how, and we will cover reasonable postage.
- Tell us if the device is lost, stolen or damaged. We will not charge you for fair wear and tear or for faults that are not your doing.
You are responsible for working safely when installing or checking the device, including when working at height or around an open tank. Installing a device does not make us responsible for your tank, your water supply or your water quality.
6. Tankful is a monitoring aid
Tankful helps you keep an eye on your tank. It is not a guarantee, and it does not replace checking your tank yourself.
- Readings, volumes and usage estimates are approximate. They depend on the sensor, how the device is installed, and the tank dimensions you enter.
- The device relies on its battery and on your Wi-Fi and internet connection. If any of these fail, readings will be delayed or missing.
- Alerts are sent by email and push notification, which rely on other companies' services and on your own devices and settings. Alerts may be late or may not arrive.
- Do not rely on Tankful as your only way of knowing how much water you have, particularly where running out could cause harm or loss, such as for stock water, firefighting supply or medical needs.
7. Water suppliers and articles
- Our water supplier directory lists independent businesses. We do not endorse them, and we are not responsible for their prices, availability, water quality or service. Any arrangement you make with a supplier is between you and them.
- If you ask us to pass a refill request to a supplier, we will share the details needed to arrange the delivery, as described in our Privacy Policy.
- Our articles are general information only, not professional advice.
8. Acceptable use
You must not:
- use the service in a way that breaks the law or anyone else's rights;
- try to gain access to accounts, sites, devices or data that are not yours;
- interfere with or overload the service, or try to get around its security or rate limits;
- copy, scrape or resell the service or its content; or
- send data to the service from anything other than a Tankful device we have provided.
9. Fees
The service is free during the pilot. If we introduce fees, we will give you at least 30 days' notice by email, and you will not be charged unless you choose to keep using the service on the new terms.
10. Intellectual property and your data
- We own the service, including the software, firmware, device designs, website content and the Tankful name and logo. These terms do not give you any rights in them other than the right to use the service.
- You own the information you enter about yourself and your sites. You give us permission to use it, and the readings from your devices, to provide and improve the service.
- We may create and use data that has been de-identified and aggregated so that it cannot identify you or your property, including after your account is closed. Our Privacy Policy explains this.
11. Ending these terms
- You can stop using the service and ask us to close your account at any time by emailing support@tankful.nz.
- We may suspend or close your account if you break these terms, if we need to for security or legal reasons, or if we end the pilot or the service. Where we reasonably can, we will give you notice first.
- When your account is closed you must return any device we have lent you (see section 5). Sections 5, 10, 12 and 14 continue to apply.
12. Our liability to you
If you are a consumer, you have rights under the Consumer Guarantees Act 1993 and the Fair Trading Act 1986 that cannot be taken away. Nothing in these terms limits those rights.
If you use the service for the purposes of a business, you agree that the Consumer Guarantees Act 1993 does not apply, and that sections 9, 12A and 13 of the Fair Trading Act 1986 do not apply, to the extent the law allows. You agree this is fair and reasonable.
Subject to the paragraphs above, and to the extent the law allows:
- the service is provided "as is", and we exclude all warranties that are not set out in these terms;
- we are not liable for loss or damage caused by a wrong, late or missing reading or alert, including a tank running dry or overflowing, the cost of emergency water, or damage to pumps, appliances, stock, crops or property;
- we are not liable for any indirect or consequential loss, or for loss of profit, revenue, data or goodwill; and
- our total liability to you for all claims connected with the service is limited to the greater of the fees you paid us in the 12 months before the claim arose and NZ$100.
13. Changes to these terms
We may update these terms from time to time. If a change is significant, we will email you at least 30 days before it takes effect. If you keep using the service after that date, you accept the updated terms. If you do not agree, you can close your account.
The date at the top of this page shows when the terms were last updated.
14. General
- These terms are governed by New Zealand law, and the New Zealand courts have exclusive jurisdiction.
- If part of these terms cannot be enforced, the rest still applies.
- If we do not enforce a right straight away, we can still enforce it later.
- You may not transfer your rights under these terms to anyone else without our written agreement. We may transfer ours to a business that takes over the service.
- These terms and our Privacy Policy are the whole agreement between us about the service.
