Privacy and local data

About this project

ElectricalDyev is not a registered company or a professional engineering service. This page is a description of the site as it operates today, not a claim of certification or compliance with every country’s rules.

Browser-local projects

Projects and saved calculation details are stored in your browser using IndexedDB. They are not uploaded as part of normal project use. You can delete them in the workspace or clear browser storage.

An exported project file leaves the browser only when you choose to save or share it. Anyone you give that file to may be able to read its contents. Keep your own backups; clearing browser data or changing devices can remove local projects.

Calculator URLs and ordinary requests

A standalone calculator URL can include entered settings in its query string. When you open or share such a URL, the URL may be visible to the hosting provider, your browser history and the recipient. Do not enter client names, addresses, account numbers or other personal or confidential information into calculator fields or URLs.

The hosting provider receives ordinary request information needed to deliver the site, such as IP address, requested URL, country hint, user agent and time. Hosting logs are separate from Google Analytics and are not controlled by the Analytics choice below.

Optional Google Analytics

If configured, Google Analytics measures page and tool usage. It can use browser identifiers and process device and approximate-location information; it is not anonymous. Our explicit events contain only page paths without query strings, generic page/category identifiers and navigation destinations. We do not intentionally send calculator inputs, calculation results or browser-local project contents as Analytics events.

Visitors in the EEA, United Kingdom and Switzerland are asked before the Google tag loads. India has a no-banner default with an opt-out. Other and unknown locations are off by default, with an opt-in available through Privacy settings in the footer. This country-based behavior is a conservative product setting, not a determination of which laws apply to you.

You can change or withdraw your Analytics choice at any time through Privacy settings. Withdrawing stops new Analytics events from this browser and attempts to remove first-party Google Analytics cookies. It cannot undo data already sent. Your choice is stored in browser localStorage; a short-lived first-party scope cookie carries the country-based setting. Blocking browser storage prevents automatic Analytics activation.

Vendors and retention

The site uses Vercel to deliver pages and, when Analytics is enabled, Google Analytics to measure site usage. These services may process information outside your country under their own service arrangements.

There is no site-managed server copy of your projects. Browser-local projects remain until you delete them or your browser removes its storage. Analytics and hosting records follow the settings and retention arrangements of those services; this page does not promise a specific period for records held by them.

Your controls

You can delete local projects in the workspace, clear browser storage, and change or withdraw your Analytics choice through Privacy settings in the footer. Depending on where you live, additional privacy rights may apply. This page does not replace advice about the rules that apply in your location.
