Privacy Policy

Introduction

This policy describes how UTELVANI handles information when you visit the website, use its tools or contact it by email.

Information we process

The calculators use the rates, readings, usage and other values you enter to compute results in your browser. The tools do not transmit these inputs to a server. Browsing the site sends ordinary requests to the web host. Email correspondence is a separate activity described below.

Browser storage and IndexedDB

When you save a monthly record, appliance configuration or rate preference, UTELVANI stores it in IndexedDB for this site in your browser profile. This may include billing months, utility types, usage, bill amounts, budgets, configuration names and rates. There is no UTELVANI account or cloud synchronization. Use the Monthly Utility Tracker to delete a bill or clear all UTELVANI records, configurations and preferences from that browser.

JSON import and export

Export creates an unencrypted JSON file on your device. Import reads and validates the selected file in the browser and asks for confirmation before merging it. Matching monthly records and appliance configurations are replaced, and matching preferences in the backup take precedence. Keep backups somewhere private. Clearing browser data does not delete copies you have already exported.

Cookies and similar technologies

The site code uses IndexedDB for local saves. It does not set cookies or use the browser’s localStorage or sessionStorage.

Server logs and hosting

When you load a page or image, the hosting infrastructure receives your IP address and the address of the requested resource. The host may log requests. Which details are recorded, if any, and how long any logs are kept have not been confirmed.

Contact emails

If you email UTELVANI, Gmail processes the message. The address, subject, message and any attachments you send may be used to understand and respond to your inquiry. A redacted description is usually enough for troubleshooting. See Contact Us for examples of what to include.

Third-party services

Site images, styles and scripts are served from the site. The pages do not embed third-party analytics, advertising or fonts. If you open an external website or send an email, the service you use handles that activity under its own policies.

Advertising and Google AdSense

UTELVANI currently uses no advertising or analytics services. It does not serve ads through Google AdSense or send ad requests to Google.

Before introducing Google AdSense or another advertising service, UTELVANI will update this policy to explain which providers are involved, what data and technologies they use, and what choices or consent apply to the service and your region.

Children’s privacy

UTELVANI is a general-audience site for people managing household utilities. It is not directed at children. The tools have no registration or date-of-birth fields. The Appliance Energy Cost Calculator has a free-text configuration name field for saved settings. Use a label such as “Kitchen fridge” and leave out personal information. If you believe a child has sent personal information by email, use the contact address below so the message can be reviewed.

Data security

Browser storage is accessible to people who can use your browser profile. Protect your device and keep exported files in a private location, especially when using a shared computer. Avoid including sensitive account details in configuration names or emails.

Data retention

Saved data remains in your browser until removed through the site or browser settings, or until the browser clears it. You control how long you keep downloaded backups. Email correspondence may be retained as needed to respond and handle related follow-up. Hosting log retention depends on the host’s settings described above.

Your privacy choices and rights

You can access, export, correct or delete your locally saved records through the tools. Depending on the law that applies, you may also have rights regarding personal information handled outside your browser, such as access, correction or deletion. Use the contact address below to describe your request and the information involved. UTELVANI cannot retrieve records stored only in your browser.

International visitors

UTELVANI can be used from different countries. Saved records stay in the browser you use. Website requests and email may be handled by infrastructure outside your country. The applicable locations depend on the hosting and email services involved.

Policy updates

Changes to how the site processes information will be reflected on this page. Review the current policy when you use a new feature or return to the site.
