1. Summary: Our Core Privacy Commitment

At Adapter Guru (adapterguru.com), your privacy is fundamental. All compatibility checks, electrical calculations (voltage, amperage, wattage, polarity, wire drop, USB-PD negotiation), and preset comparisons are executed 100% locally inside your web browser (client-side).

We do not require user accounts, we do not track your IP address, and we do not store, log, or transmit any values you input into our calculators to any server.

2. Information We Do NOT Collect

No Personal Identifiable Information (PII): We do not collect your name, email, physical address, or phone number.
No Calculator Input Logging: Voltage, current, polarity, or device selections you enter remain entirely in your browser memory and URL hash.
No Payment Data: Adapter Guru is completely free to use. We do not collect credit cards or financial data.

3. Cookies and Local Storage

Adapter Guru uses localStorage solely to remember your UI display preference (Light Mode vs. Dark Mode). This preference is stored locally on your device and is never transmitted to us. We do not use persistent tracking cookies or third-party marketing cookies.

4. Web Hosting & Infrastructure

Adapter Guru is statically generated and hosted via global Content Delivery Network (CDN) edge servers. Standard ephemeral web server logs (such as request timestamps and HTTP status codes) may be collected automatically by hosting providers for security and DDoS mitigation. These logs do not contain personal user data.

5. Third-Party Links

Our website may contain reference links to manufacturer documentation, external specification sheets, or electrical standards. We are not responsible for the privacy practices or content of third-party websites.

6. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. Any changes will be posted directly on this page with an updated revision date.
