Privacy Policy
Effective Date: September 2026 // Our commitment to client-side confidentiality, zero-storage IP calculation, and transparent advertiser disclosure.
At ipvsubnetcalculator.com, the privacy of our visitors is paramount. This Privacy Policy outlines the types of information received, recorded, and handled by ipvsubnetcalculator.com and governs your use of our networking tools.
01 // Client-Side Computation & Zero IP Retention
All subnetting computations, bitwise operations, binary conversions, and network divisions execute 100% locally within your client browser's JavaScript runtime.
02 // Web Server Log Files
Like most standard web servers, ipvsubnetcalculator.com may temporarily log standard diagnostic HTTP request metadata (such as browser user-agent, referer headers, timestamp, and coarse ISP network ASN) solely for DDoS mitigation, infrastructure health monitoring, and security firewalls. These generic metrics are not linked to your calculator inputs.
03 // Cookies & Google AdSense
We use cookies and third-party advertising services (including Google AdSense) to keep our computational tools free for global network engineers. Google may use cookies (such as the DoubleClick DART cookie) to serve relevant advertisements based on visits to this and other websites across the Internet. You can opt out of personalized advertising by visiting Google Ad Settings.
04 // GDPR & CCPA Rights
Under the General Data Protection Regulation (GDPR) and California Consumer Privacy Act (CCPA), users have rights to request data transparency, deletion, and non-discrimination. Since our tools process network inputs locally without recording personal identities or database profiles, we do not sell or monetize personal consumer records.
