Privacy Policy

Solder Hub ("Solder Hub," "we," "us," or "our") operates the website and services at solderhub.com (the "Service"). We are based in Bhubaneswar, Odisha, India.

For privacy-related questions or to exercise your rights, contact us at privacy@solderhub.com or through our Contact page.

This Privacy Policy applies to information we collect through the Service, including when you browse projects, create or administer an account, submit content, subscribe to our newsletter, or interact with embedded tools such as Wokwi simulations.

Third-party websites and services linked from Circuit Hub (for example, GitHub, Discord, or external documentation) have their own privacy practices. We encourage you to review their policies before sharing information with them.

Information you provide

• Account data — Name, email address, username, password (stored in hashed form), and profile details you choose to add.
• Submissions — Project titles, descriptions, schematics, code snippets, images, and metadata you upload through Submit Project or admin tools.
• Communications — Content of emails or messages you send to support, privacy, or partnership addresses.
• Newsletter — Email address when you subscribe to updates (you may unsubscribe at any time).

Information collected automatically

• Usage data — Pages viewed, links clicked, search queries, simulation interactions, and approximate session duration.
• Device & log data — IP address, browser type, operating system, referring URL, and timestamps stored in server logs for security and debugging.
• Cookies & similar technologies — See Section 8 below.

We do not intentionally collect sensitive categories of personal data (such as health, biometric, or government ID numbers) unless you voluntarily include them in a submission, which we discourage.

We use personal information to:

• Provide, operate, and maintain the Service
• Authenticate users and secure accounts
• Display, moderate, and improve community-submitted projects
• Respond to support requests and enforce our Terms of Service
• Send administrative notices, security alerts, and (with consent) newsletters
• Analyze aggregated usage to improve content, performance, and accessibility
• Comply with legal obligations and protect against fraud or abuse

We do not sell your personal information. We do not use your email for third-party advertising without your explicit consent.

If you are in a region that requires a legal basis for processing (such as the EEA, UK, or under India's Digital Personal Data Protection Act, 2023), we rely on:

• Contract — Processing necessary to provide the Service you requested
• Legitimate interests — Security, analytics, product improvement, and fraud prevention, balanced against your rights
• Consent — Newsletter emails and non-essential cookies where required
• Legal obligation — When law requires retention or disclosure

We may share information in these limited circumstances:

• Service providers — Hosting (e.g. Vercel), analytics, email delivery, and infrastructure partners who process data on our instructions and under confidentiality obligations.
• Embedded partners — When you open a Wokwi lab or similar embed, that provider may receive technical data according to their own policy.
• Public content — Projects you publish may display your chosen author name and materials to all visitors.
• Legal & safety — When required by law, court order, or to protect rights, safety, and integrity of the Service.
• Business transfers — In connection with a merger, acquisition, or asset sale, subject to continued protection of your data.

Our infrastructure providers may process data in countries other than India, including the United States and the European Union. Where required, we implement appropriate safeguards (such as standard contractual clauses) for cross-border transfers.

We use cookies and similar technologies for:

• Essential operation — Session management, authentication, and security
• Preferences — Theme (light/dark) and display settings
• Analytics — Aggregated visit metrics via Vercel Analytics to understand how the Service is used

You can control cookies through your browser settings. Disabling essential cookies may limit certain features. Where local law requires consent for non-essential cookies, we will request it before enabling those technologies.

We retain personal information only as long as needed for the purposes described in this policy, unless a longer period is required by law.

• Account data — Until you delete your account, plus a short backup window
• Server logs — Typically up to 90 days unless needed for security investigations
• Support emails — Up to 24 months unless you request earlier deletion
• Published projects — May remain after account deletion if licensed for community use; contact us to remove specific content

We implement reasonable technical and organizational measures — including encryption in transit (HTTPS), access controls, and hashed credentials — to protect your information. No method of transmission or storage is 100% secure; if you believe your account has been compromised, contact support@circuithub.com immediately.

Circuit Hub is not directed at children under 13 (or the minimum age in your jurisdiction). We do not knowingly collect personal information from children. If you believe a child has provided us data, contact privacy@circuithub.com and we will delete it promptly.

Depending on where you live, you may have the right to:

• Access a copy of personal data we hold about you
• Correct inaccurate information
• Delete your data (subject to legal exceptions)
• Restrict or object to certain processing
• Withdraw consent where processing is consent-based
• Port your data in a machine-readable format where technically feasible
• Lodge a complaint with a supervisory authority

To make a request, email privacy@circuithub.com from the address linked to your account. We may verify your identity before fulfilling the request. We aim to respond within 30 days.

We may update this Privacy Policy from time to time. We will post the revised version on this page with an updated effective date. Material changes may be communicated via email or a prominent site notice. Continued use after changes take effect constitutes acknowledgment of the updated policy.
