Terms of Service

What the site provides

UTELVANI offers household electricity and water calculators, educational guides, worked examples and a browser-local tracker. The site does not supply utilities, access provider accounts, issue official bills or provide engineering, plumbing, financial or legal services.

Using the tools

Choose the model that fits the question and review the formula and units shown with your result. You are responsible for entering and checking your usage, currency, rates and billing dates. Sample inputs illustrate how a tool works. Check important figures against your provider’s statement and tariff.

Electricity and water estimates

Rated power describes equipment under particular conditions. Actual power can vary with the operating mode, thermostat, load and standby draw. Use measured or representative inputs where possible. Match water volume to the unit priced by your provider and check whether sewer charges apply to that same volume.

Tariffs differ by location, provider and billing period. Check tier boundaries, the tax base, fixed charges, time-of-use prices, minimum charges and credits. A result reflects the charges included in the selected calculation and may differ from the amount billed.

Savings scenarios

Energy and water comparisons depend on the power, flow, runtime, frequency and rates you assume. Actual costs can change with weather, behavior and tariff rules. Use the comparisons to understand how an input changes the estimate and verify results with actual usage and bills.

Local records and backups

The tracker stores the amounts you enter in your browser. Export a JSON backup and keep a copy of important records. Clearing browser data, deleting records, device failure or browser storage limits can make saved records unavailable. Check the file you import before accepting a merge that replaces matching records. See the Privacy Policy for details.

Acceptable use

Use the site lawfully. Respect other people’s rights and avoid actions that disrupt access, compromise security or place unreasonable load on the service.

Intellectual property

You may use the tools and results for your own purposes. Original site text, design and graphics remain subject to applicable intellectual property rights. Third-party photography remains subject to its applicable licenses and rights. Your entries and exported records remain yours.

External links

External sites set their own terms and privacy practices. Check the provider’s current information before relying on an external tariff, specification or service.

Availability and responsibility

Tools or pages may change or be unavailable, and estimates may differ from real charges. Verify material decisions with an appropriate source. To the extent permitted by applicable law, UTELVANI is not responsible for records lost solely because of events outside its control, such as a device failure or the user clearing browser data. This limitation does not apply to loss caused by a defect in the site or by actions within UTELVANI’s control. You retain all rights and remedies that cannot be limited under applicable law.

Changes to these terms

When the site or its terms change, the current terms will be published on this page.
