• Applicable law: If negotiation fails, disputes shall, to the maximum extent permitted by law, be handled preferentially with reference to generally accepted international commercial practice and open-source community conventions, avoiding unnecessary cross-border litigation costs.

BG7BAG reserves the right to amend these terms at any time. Amended terms take effect upon publication; continued use of the Service constitutes acceptance of the amended terms.

This website follows the principle of data minimization and avoids collecting users’ personally identifiable information (PII) wherever possible:

• Access logs and de-identification: Hosting providers (e.g., Hostinger, Cloudflare) automatically record basic network logs (such as IP addresses, browser types, and request times) during operations. Such logs are used solely for DDoS mitigation, abuse prevention, and system stability. To the extent technically feasible and operationally necessary, this site applies strict security isolation and de-identification safeguards to log data, and will never associate access logs with users’ personal identities or subject them to secondary data mining.
• Voluntarily submitted data: If you email contact@bg7bag.com or contact the editor via Ko-fi, such interactions are initiated voluntarily by you and used solely to respond to your inquiries.
• Radio contact data: Callsigns, QSO logs, QSL card notes, and similar content on this website constitute public technical exchange information within the amateur radio community.

• Embedded content: Pages on this site may embed content from third-party platforms (e.g., videos, code snippets, maps). When accessing such embedded content, third-party providers may process your data in accordance with their own privacy policies.
• Sponsorship and payments: All donations are processed directly by redirecting to third-party platforms (e.g., Ko-fi). This website does not touch or store any of your credit card information or sensitive payment credentials.

• Europe / EU and UK (GDPR / UK GDPR):
  The lawful basis for processing basic access logs is “Legitimate Interest”, namely maintaining network and information security. EU/UK residents enjoy the rights of access, rectification, erasure (“right to be forgotten”), and restriction of processing.
• Mainland China (PIPL):
  This site does not proactively collect sensitive personal information in mainland China. The collection and processing of basic system access logs (including IP addresses) are based on the lawful and necessary purposes of safeguarding network security and normal system operation, handled solely by hosting providers’ automated security systems, and are not used to identify specific natural persons.
• Japan (APPI):
  Under Japan’s Act on the Protection of Personal Information, logs and voluntarily submitted contact data collected by this site are used solely for the stated operational and response purposes and are never provided to third parties without consent.
• Hong Kong, China (PDPO) and Malaysia (PDPA 2010):
  This site strictly follows local data protection principles and pledges not to use user interaction data for unauthorized commercial marketing.
• United States (CCPA/CPRA):
  This site does not “Sell” or “Share” any user’s personal information (as defined by the CCPA/CPRA).

• No sale of data: This website will never sell, rent, or trade any user information to third parties.
• Encrypted transmission: The entire site uses HTTPS/TLS encrypted communication to safeguard data in transit.

If you have any questions about this site’s privacy practices, wish to exercise data subject rights (e.g., requesting access, rectification, or erasure), or have DMCA takedown/counter-notice matters, please contact the editor through the official channels above.
