CONFIDENTIALITY & COMPLIANCE

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.

1. 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.

Confidentiality Guarantee: We do not transmit, log, record, harvest, or store any IP addresses, subnet masks, CIDR prefix selections, or network topologies you input into our calculators. Your corporate IP allocations and private VPC designs remain strictly on your device.

2. Web Server Log Files

Like virtually all standard web server infrastructures, ipvsubnetcalculator.com makes use of basic edge server log files for operational reliability, DDoS defense, and infrastructure diagnostics. Information inside log files may include your public internet protocol (IP) address, browser user-agent, operating system, Internet Service Provider (ISP), date/time stamp, referring/exit pages, and basic request paths. This diagnostic telemetry is unlinked to any personally identifiable information and is automatically recycled periodically.

3. Cookies & Browser LocalStorage

Our application utilizes browser localStorage solely to remember your UI preference between visits:

Theme Preference: Stores whether you selected light mode or dark mode (key: theme).

We do not use tracking cookies for first-party analytical profiling, nor do we require user registration, logins, or authentication cookies.

4. Google AdSense & Advertising Partners

We may display advertisements served by Google AdSense and accredited third-party advertising networks to support the maintenance and free operation of this platform.

Google, as a third-party vendor, uses cookies (such as the DoubleClick DART cookie) to serve ads based on prior visits to our site or other websites across the web.
You can opt out of personalized advertising by visiting the Google Ads Settings page.
Alternatively, you can opt out of third-party behavioral advertising cookies by visiting www.aboutads.info or Your Online Choices (EU).

5. European GDPR & California CCPA Rights

Under the General Data Protection Regulation (GDPR) and California Consumer Privacy Act (CCPA), individuals hold specific statutory rights regarding their personal data (including rights of access, rectification, erasure, and opt-out of personal data sales). Because ipvsubnetcalculator.com operates as an anonymous, registration-free utility and does not store personal profiles, we do not monetize or sell consumer personal information.
