Privacy Policy

1. Our Architectural Foundation: Pure Client-Side Processing

TelecomCalculators (accessible at https://telecomcalculators.com) was designed from its initial inception with a foundational engineering constraint: absolute computational privacy through client-side mathematical execution.

When you interact with any computational module across our catalog—whether computing optical attenuation budgets, dimensioning telecommunications trunk groups via Erlang recurrence algorithms, calculating 5G NR physical resource block (PRB) allocations, or determining data center electrical circuit loads—all numerical equations execute strictly within your local web browser environment (e.g., Google Chrome V8 engine, Mozilla SpiderMonkey, Apple WebKit JavaScriptCore).

This architectural choice guarantees that telecommunications architects, defense contractors, carrier engineers, and enterprise security professionals can evaluate sensitive or proprietary infrastructure scenarios—such as internal IP address spaces, microwave transmission hops between classified coordinates, or private trunk capacity models—with complete certainty that their proprietary topologies remain confined to their local endpoint RAM.

2. Information We Do Not Collect

Because TelecomCalculators provides open-access engineering utilities, our operational philosophy is strictly anti-surveillance. We purposefully do not implement mechanisms to collect, harvest, or aggregate sensitive personal data. Specifically:

• No User Account Credentials: We do not operate user registration databases. We do not solicit, collect, or store your legal name, username, email address, password, physical address, employer, job title, or phone number.
• No Financial or Payment Information: TelecomCalculators is 100% free to access. We do not collect credit card numbers, debit card details, bank account identifiers, billing addresses, or cryptocurrency wallet keys.
• No Calculation Persistence Databases: We do not log, catalog, or archive calculation histories, inputted values, output reports, or scenario parameters on our server disks or backend data warehouses.
• No Special Category / Sensitive Data: We do not collect any data revealing racial or ethnic origin, political opinions, religious or philosophical beliefs, trade union membership, genetic or biometric data, health metrics, or sexual orientation.

3. Information Automatically Collected by Web Hosting & Infrastructure

Like virtually all web properties connected to the global Internet, our edge hosting infrastructure, Content Delivery Networks (CDNs), and reverse proxy services (such as Cloudflare, Google Cloud, or AWS CloudFront) automatically capture standard, transient web server request logs when your browser requests an HTML, CSS, JavaScript, SVG, or icon asset.

These automated server transaction logs typically contain the following technical parameters:

• Internet Protocol (IP) Address: The numeric address assigned to your network gateway by your Internet Service Provider (used solely for packet routing, geo-distributed CDN caching, and DDoS defense).
• User-Agent String: The browser version, rendering engine, and operating system family reported by your client (used to serve compatible web standards).
• Uniform Resource Locator (URL) & Referrer Header: The specific page requested (e.g., /reference/) and the preceding URL from which a hyperlink was followed.
• Timestamp & Protocol Status: Date and time of the asset request, HTTP response status code (e.g., 200 OK, 404 Not Found), and byte volume transferred.

Purpose and Retention: These logs are maintained strictly for legitimate operational purposes under GDPR Article 6(1)(f): preserving web infrastructure availability, detecting malicious automated scrapers or volumetric denial-of-service (DDoS) attacks, resolving network routing anomalies, and ensuring TLS encryption integrity. These technical logs are rotated, aggregated, and permanently purged on a standard ephemeral schedule (typically within 14 to 30 days) and are never cross-referenced with individual user identities.

4. Third-Party Advertising Networks & Cookie Disclosures (Google AdSense Policy)

To finance the continuous hosting, mathematical verification, standards updates, and technical maintenance of TelecomCalculators as a freely accessible resource, we partner with reputable third-party advertising networks, including Google AdSense (operated by Google LLC, 1600 Amphitheatre Parkway, Mountain View, CA 94043, USA).

In accordance with Google Publisher Policies, the Google EU User Consent Policy, and applicable statutory privacy mandates, we provide the following explicit disclosures regarding advertising technologies:

How Google and Third-Party Vendors Use Cookies

• Third-party vendors, including Google, use cookies and web beacons to serve advertisements based on a user's prior visits to this website or other websites on the Internet.
• Google's use of advertising cookies enables it and its partners to serve ads to users based on their visit to TelecomCalculators and/or other sites on the Internet.
• Google uses the DoubleClick DART cookie to serve interest-based advertisements across the Google Display Network and Google Ad Manager partner sites. The DART cookie tracks user browsing patterns across disparate domains to infer consumer preferences without capturing personal names, email addresses, or physical locations.

Personalized vs. Non-Personalized Advertisements

Depending on your geographic location and your selections within our Consent Management Platform (CMP), ads served to you may be either:

• Personalized Advertisements: Ads selected based on your inferred interests, demographics, previous web browsing history, and mobile app usage. In regions subject to GDPR or CCPA/CPRA, personalized advertising is only deployed where legally valid consent has been affirmatively recorded or where opt-out rights have not been exercised.
• Non-Personalized Advertisements (NPA): Ads selected based strictly on contextual indicators relevant to the current page (e.g., telecommunications engineering, optical networking equipment, RF test sets) and broad geographic indicators (such as city or regional level derived from truncated IP addresses). Although non-personalized ads do not use cookies for user profile targeting, they do utilize cookies for technical frequency capping, aggregated ad reporting, and combating fraud and abuse.

5. Cookies, Web Beacons & Local Storage Technologies

TelecomCalculators uses standard browser technologies including cookies, web beacons, and HTML5 Web Storage (comprising localStorage and sessionStorage) to ensure site functionality and support advertising infrastructure.

How to Manage and Disable Cookies in Your Browser
