Privacy Policy

1. Notebook Scope & Purpose

OpenRF Note (“we,” “us,” or “our”) is an open-source technical notebook documenting unlicensed radio frequency systems, FCC Part 15 rules, Wi-Fi environment detection, LoRa mesh networking, and RF diagnostic engineering.

This site is published for educational, hobbyist, and engineering reference. We do not provide commercial client IT services, customer ticketing, or managed infrastructure, and this policy applies to your visits and communications with openrfnote.com.

2. Information We Collect

We collect minimal information necessary to deliver site content, authenticate supporters, prevent abuse, and communicate with readers:

Information you provide directly: When you submit a message through our contact form, you may provide your name, email address, radio callsign or handle (optional), topic, and message text. Please do not submit sensitive personal, financial, or confidential information through website forms.

Members site sign-in: Reading this site needs no account. Supporters who sign in to the members site do so through Clerk, which handles the account and email address from its own pages at accounts.openrfnote.com. The members site receives from Clerk a user ID, whether the account is marked as a supporter, and the account’s email address, which is shown on the account page. Passwords, credit card numbers, billing addresses, and banking details are not received, processed, or stored by this site.

Information collected automatically: When you browse this site, our edge hosting infrastructure automatically records standard technical data, such as your IP address, browser user-agent, referring URL, pages visited, timestamps, and diagnostic security logs.

3. How We Use Information

Information collected through OpenRF Note is used exclusively for legitimate notebook operations:

• To read and respond to technical questions, feedback, and errata sent through our contact form.
• To sign supporters in to the members site and grant early access to draft field notes.
• To monitor, maintain, and optimize site reliability, rendering speed, and reader usability.
• To detect, prevent, and mitigate automated spam, bot abuse, security threats, or malicious traffic.
• To comply with applicable legal, regulatory, or technical obligations.

We do not sell personal data, do not rent email lists, and do not use your contact information for unsolicited commercial marketing blasts or advertising networks.

4. Cookies, Analytics & Cloudflare Turnstile

We use lightweight, privacy-respecting mechanisms to run the site:

Sign-in cookies: Signing in to the members site sets Clerk’s cookies on openrfnote.com and its subdomains (including members.openrfnote.com, accounts.openrfnote.com and Clerk’s sign-in service at clerk.openrfnote.com). Clerk manages them; they keep the sign-in active. The public site neither sets nor reads them. Public reference guides and published notes require no cookie and set no session state.

Cloudflare Turnstile: Our contact form uses Cloudflare Turnstile to verify human submissions without invasive visual puzzles or cross-site tracking cookies.

Edge Analytics: Cloudflare provides privacy-first, aggregate metrics (bandwidth, HTTP status codes, top paths) without persistent tracking cookies or fingerprinting.

5. Third-Party Links & Services

This site connects with trusted platforms for infrastructure and community support:

Clerk: Supporter sign-in on the members site (see the Support page) is provided by Clerk, which handles the account and email address as processor under Clerk’s own terms and privacy policy.

External Reference Resources: Links pointing to FCC rules (eCFR Part 15), hardware datasheets, Semtech/TI silicon errata, or open-source repositories navigate to third-party domains whose privacy practices we do not govern.

6. Data Retention, Security & Your Choices

Contact submissions are retained only as long as needed to address your feedback or keep records of corrections. Edge server logs are kept on standard rolling retention schedules and purged regularly.

All traffic is encrypted in transit over HTTPS (TLS). To request deletion of a prior message or inquiry, contact us through our contact form or by email at info@openrfnote.com.

7. Updates & Contact Information

We may update this Privacy Policy periodically. Modifications will appear here with an updated revision date.
