de:volt is operated by the de:volt team. Until dedicated department inboxes are introduced, all legal, privacy, accessibility, billing, education, support, and security enquiries should be sent to dev@kapadia.biz.

If you use de:volt for an organisation, school, company, or other entity, you represent that you have authority to bind that entity to these terms.

By accessing or using de:volt, you agree to these terms and to the Privacy Policy. If you do not agree, do not use the service.

de:volt is evolving quickly. We may update these terms, add or remove features, alter limits, or discontinue beta features. If a change is material, we will take reasonable steps to notify affected users, such as by updating this page, showing in-product notice, or contacting the account email.

You must provide accurate account information and keep your sign-in methods secure. Magic-link and OAuth sign-in links are personal to you. You are responsible for activity under your account unless the activity resulted from de:volt failing to use reasonable security practices.

You may not use de:volt if you are prohibited from doing so by applicable law, sanctions, school rules, employer rules, or these terms.

de:volt Learn supports teachers, schools, classes, student accounts, assignments, progress tracking, and live classroom sessions. A school, teacher, or other education administrator who invites students or uses de:volt with students is responsible for having all authority, notices, permissions, and consents required by applicable law and school policy.

Children under 13, or under the local age requiring parent, guardian, or school authorisation, may use de:volt only through a school, parent, guardian, or other authorised adult. de:volt Learn must not be used to collect unnecessary personal information from students or to send students unlawful, harmful, or inappropriate content.

Your projects, circuit files, lessons, assignments, comments, prompts, labels, names, and other content remain yours or your organisation's. You grant de:volt a worldwide, non-exclusive, royalty-free licence to host, copy, process, transmit, display, back up, and otherwise use that content only as needed to provide, secure, debug, improve, and support the service.

You are responsible for ensuring that your content is lawful, does not infringe anyone else's rights, and is appropriate for the audience that can access it. We may remove content or restrict access where we reasonably believe it violates these terms, exposes others to risk, or could create legal or operational harm.

You must not use de:volt to:

• break the law or violate another person's rights;
• upload or share unlawful, infringing, deceptive, abusive, hateful, sexual, exploitative, or otherwise harmful content;
• harass, monitor, profile, or discriminate against students or other users;
• attempt to bypass authentication, row-level security, subscriptions, usage limits, or technical controls;
• probe, scrape, overload, reverse engineer, or interfere with de:volt beyond what applicable law expressly permits;
• submit secrets, regulated data, or sensitive personal information unless de:volt has expressly agreed to handle it; or
• use the simulator, AI assistant, or generated outputs for safety-critical, regulated, hazardous, or production engineering without independent professional verification.

de:volt is an educational and prototyping tool. Simulation results, voltage and current readings, oscilloscope views, Arduino behaviour, component models, and AI-generated designs are approximations. They are not certification, compliance testing, professional engineering advice, or a substitute for datasheets, lab instruments, design reviews, or qualified professional judgement.

Do not rely on de:volt for mains voltage, high-current systems, batteries outside safe hobby ranges, medical devices, vehicles, aviation, emergency systems, industrial control, life-safety systems, regulated products, or any system where an error could cause injury, property damage, legal non-compliance, or financial loss. You are responsible for what you build, purchase, connect, test, and share.

The Pro AI assistant can review, explain, generate, and propose edits to circuits. AI outputs can be incomplete, incorrect, unsafe, or unsuitable for your use. You must review and test all AI outputs before accepting them or using them in any real-world build.

AI requests may send your prompt and a compact circuit snapshot to third-party AI providers. Do not include confidential, export controlled, regulated, student-sensitive, or otherwise sensitive information in prompts unless you have authority to do so and accept that processing. The Privacy Policy explains current AI processing.

Free and guest use may be limited by feature, project, component, storage, AI, rate, or availability caps. Pro subscriptions are billed through Stripe and currently shown in AUD. Checkout may collect billing address information and may apply taxes through Stripe automatic tax.

Unless stated otherwise at checkout, subscriptions renew monthly until cancelled. You can manage or cancel a subscription through the Stripe customer portal linked in Billing settings. Cancelling stops future renewals but does not automatically refund past charges. Refunds are provided only where required by law or where de:volt agrees in writing. Nothing in these terms excludes non-excludable consumer guarantees, refund rights, or other statutory rights.

We may change prices or plan inclusions with reasonable notice. If a school, university, or organisation buys an annual or managed plan, any order form, quote, invoice, data-processing terms, or written agreement signed by de:volt controls where it conflicts with these self-serve terms.

de:volt uses third-party providers for hosting, authentication, database services, billing, analytics, error monitoring, email, and AI. These services may process data as described in the Privacy Policy and may have their own terms when you interact with them directly, such as Stripe Checkout or a Google sign-in flow.

de:volt, its software, branding, interface, documentation, component catalog, simulation engine, and related materials are owned by de:volt or its licensors and are protected by intellectual property laws. These terms do not transfer ownership of de:volt intellectual property to you.

If you send feedback, ideas, bug reports, feature requests, or suggestions, you grant de:volt permission to use them without restriction or compensation, while you keep ownership of any rights you already have in that feedback.

Our handling of personal information is described in the Privacy Policy and Cookie Notice. Schools and teachers should also read the Education Data Notice. You must not use de:volt to collect or process personal information unless you have a lawful basis and all required notices, permissions, and agreements.

We may suspend, restrict, or terminate access if we reasonably believe you violated these terms, created risk for de:volt or others, failed to pay, attempted to abuse the service, or if we must do so to comply with law or a provider requirement. You may stop using de:volt at any time and may delete your account from account settings where available.

To the maximum extent allowed by law, de:volt is provided "as is" and "as available". We do not promise that the service will be uninterrupted, error-free, secure, compatible with every browser or device, or that simulation, AI, learning, billing, or analytics features will meet your requirements.

Some laws, including Australian Consumer Law and other consumer protection laws, may provide guarantees or rights that cannot be excluded. Nothing in these terms limits those rights.

To the maximum extent allowed by law, de:volt is not liable for indirect, incidental, special, consequential, exemplary, or punitive damages; loss of profit, revenue, goodwill, data, opportunity, or business interruption; or losses arising from real-world builds, purchases, hardware failures, unsafe circuits, AI outputs, third-party services, or unauthorised use of your account.

Where liability cannot be excluded but can be limited, our liability is limited, at our option and where legally permitted, to resupplying the affected service or refunding the amount you paid for the affected service during the period giving rise to the claim.

To the extent allowed by law, you agree to indemnify de:volt against claims, losses, liabilities, damages, costs, and expenses arising from your content, your real-world use of circuits or AI outputs, your violation of these terms, your misuse of the service, or your failure to obtain required permissions for organisational, classroom, or student use.

These terms are governed by the laws of New South Wales, Australia, except where mandatory local law gives you non-excludable rights. Before starting formal proceedings, please contact dev@kapadia.biz and give us a reasonable opportunity to resolve the issue informally.
