Terms of Use

LogicBench is a free, browser-based digital logic design and circuit simulator provided for educational and hobbyist use. By using the site, you agree to these terms.

LogicBench is operated by Muhammad Ibrahim, its founder. You can contact him about these terms at logicbench.support@gmail.com or through the contact page.

LogicBench models component behavior — including electrical, timing, and burn-out physics — as accurately as reasonably possible, but it is a simulation. We don’t guarantee that every circuit that behaves correctly in the simulator will behave identically on real hardware, and LogicBench should not be relied on as the sole verification step for safety-critical or production circuits.

LogicBench’s software, simulation engine, design, branding, and site content are owned by Muhammad Ibrahim, who operates LogicBench, and protected by copyright and other applicable intellectual property laws. You may use the site for personal, educational, and hobbyist purposes; you may not copy, redistribute, reverse-engineer, or create derivative products from LogicBench’s underlying code or content without prior written permission.

You agree not to:

• Use the site in any way that violates applicable laws or regulations.
• Attempt to disrupt, reverse-engineer, or gain unauthorized access to the site’s infrastructure.
• Use automated tools to scrape or overload the site beyond normal personal use.

LogicBench is provided “as is” without warranties of any kind, express or implied. We don’t guarantee the site will be uninterrupted, error-free, or fit for any particular purpose.

To the extent permitted by law, LogicBench and its operator are not liable for any indirect, incidental, or consequential damages arising from your use of the site, including any real-world circuit or project built based on simulation results.

Classroom is optional and separate from the free public simulator, which never requires an account. Classroom is currently in beta, so features may change.

• Give accurate details when you register and keep your password confidential. You are responsible for activity under your account.
• Teachers can see the circuits students save or submit in their own classrooms, with timestamps, as described in the Privacy Policy.
• A student can leave a classroom at any time; leaving permanently deletes their membership and saved work in that classroom. You can also ask for your account and its data to be deleted by contacting us.
• Classroom accounts are not intended for children under 13, consistent with the Privacy Policy.

When you create an account you are asked to accept these terms, and we record which version you accepted and when.

The site uses third-party services (including Google Analytics, Microsoft Clarity, and Google AdSense) as described in our Privacy Policy. Ads shown on the site are served by Google and its partners; we don’t control the content of individual ads.

Payments, including voluntary support, are processed by independent payment providers (currently Polar and Stripe) under their own terms and privacy policies. We don’t receive or store your card details. We aren’t responsible for the services, security or privacy practices of third-party providers, but if a payment goes wrong, contact us and we’ll help where we can.

Contributions made through the “Support Development” page are voluntary and don’t unlock paid features — LogicBench’s simulator remains free to use regardless of whether you contribute.

We may update these terms from time to time. Continued use of the site after changes are posted means you accept the updated terms.
