Privacy Policy

What we do not collect

• No name, email address, telephone number or postal address.
• No account — there is nothing to register for.
• No cookies, and no advertising or cross-site tracking of any kind.
• No advertising code, no web fonts and no social media buttons.
• No fingerprinting, no session recording, no heat maps.

What happens to the values you enter

Every calculation runs inside your own browser using JavaScript that was delivered with the page. The component values you type are never transmitted to us or to anyone else, because no server is involved in the calculation at all.

You can verify this yourself: open your browser's developer tools, watch the network panel, and enter a value. No request is sent.

What is stored on your device

Small preferences are saved in your browser's local storage so the site behaves the way you left it:

• Your light or dark theme choice.
• The network you were last working on in each calculator, so switching between series, parallel and mixed does not lose your values.

More about local storage

Local storage is not a cookie. It is never sent to a server, it is not readable by other websites, and it contains no personal information. Clearing your browser data removes it, and the site continues to work normally without it.

Visitor statistics

We use Cloudflare Web Analytics to count page views. It sets no cookies and does not build a profile of you or follow you between sites.

Our web host keeps standard server logs, which include IP addresses, for security and abuse prevention. Those logs are not used to identify individuals and are not combined with any other data.

Email you send us

If you email us, we hold that message in our mailbox in order to reply, in the same way any correspondence is held. We do not add you to a mailing list and we do not share your address.

Sharing and selling

We do not sell, rent, trade or share data with anyone. There is nothing to sell.

Your rights

Data protection law in Bangladesh, and the GDPR if you are in the European Union, gives you rights to access, correct and erase personal data held about you, and to object to its processing.

Because we hold no personal data about you, there is nothing for us to produce, correct or erase. If you believe we hold something about you, write to contact@neocircuitslab.com and we will investigate and respond.

Children

This site is intended for engineers, technicians and students. It collects no data from any visitor, including children.

Changes to this policy

If we ever add a feature that collects data — a contact form that stores messages, saved projects, or accounts — this page will be rewritten before that feature goes live, not afterwards.
