Privacy Policy
Effective Date: January 1, 2026 • Last Revised: September 11, 2026
At Plumbing Tools Hub (accessible at https://plumbingtoolshub.com), your privacy is our foundational priority. We operate under a strict Zero-Data-Storage Client-Side Model—meaning your calculation inputs, pipe dimensions, fixture counts, and takeoff parameters never leave your local web browser.
100% Client-Side Math
Calculations, slope math, and sizing algorithms execute locally via JavaScript. Zero project data is transmitted to servers.
No Personal Profiling
We do not sell, rent, monetize, or harvest user data or trade takeoff measurements to third-party data brokers.
Local Preferences Only
Unit settings (Imperial vs. Metric) and dark/light mode states are stored solely in your local browser storage.
1. Introduction & Scope
This Privacy Policy applies to all services, web tools, sizing charts, schematic generators, and technical documentation hosted on Plumbing Tools Hub ("we", "us", "our", or "the Platform"). By accessing or using any part of our website, you consent to the data practices and transparency guidelines set forth in this policy.
Our website is built primarily as a suite of engineering utilities for plumbers, mechanical piping designers, hydronic contractors, estimators, and building engineers. We believe professional engineering calculations should be frictionless, instantaneous, and private.
2. Technical Architecture: Zero Server-Side Calculation Storage
Unlike traditional SaaS cloud applications that require user accounts and store estimation sheets on remote databases:
- In-Browser Execution: All pipe volume calculations, fluid weight analyses, Hazen-Williams flow equations, drain grade pitches, water heater BTU requirements, and CAD canvas drawings execute entirely within your browser runtime engine using client-side JavaScript.
- No Calculation Logging: We do not log, inspect, transmit, or retain your proprietary job site dimensions, fixture schedules, line lengths, or pricing takeoff metrics.
- No Mandatory Account Registration: You can access 100% of our calculators, conversion tables, and sizing tools without creating an account, registering an email, or providing personal credentials.
3. Information Collected Automatically
When you browse our platform, standard non-personally identifiable diagnostic information may be recorded by our web servers or content delivery network (CDN) for operational stability:
| Data Point | Purpose | Retention & Storage |
|---|---|---|
| Server Log Files | IP address, browser type, referral URLs, operating system, and HTTP response codes to monitor site uptime and prevent malicious DDoS attacks. | Aggregated, non-identifying server logs purged automatically on rolling cycles. |
| Aggregated Analytics | Anonymized page views, session duration, and device screen resolutions to identify broken links and optimize mobile usability. | Anonymized aggregate telemetry without PII mapping. |
| Local Storage / Cookies | Remembering user preferences (e.g. Dark Mode vs. Light Mode, default Unit System [Imperial / Metric]). | Persists only in your client browser; can be cleared at any time. |
4. Cookies & Browser Storage Policy
Cookies are tiny data files stored on your local device. We utilize essential functional cookies and local storage tokens to deliver an intuitive experience:
- Functional Preferences: Saving your active UI theme (Dark/Light) and preset calculator unit configurations so you don't have to re-select Imperial or Metric on every page visit.
- Session State: Maintaining canvas state in our interactive CAD drawing tools while you are working in your active browser tab.
- Managing Cookies: You can manage, reject, or delete cookies at any time via your browser settings (Chrome, Firefox, Safari, Edge). Disabling cookies will not break calculator functionality, though your theme preferences may reset upon page refresh.
5. Third-Party Services & Advertising
To maintain free access to our calculators for apprentices and contractors worldwide, we may partner with reputable third-party technology providers:
- Content Delivery Networks (CDNs): Fast, secure asset delivery through trusted edge caching providers.
- Analytics Providers: We may utilize privacy-respecting analytics tools to evaluate traffic density and optimize computation speed.
- External Links: Our educational guides link to engineering code bodies (e.g. International Code Council [ICC], IAPMO, ASME, ASTM, NFPA). We are not responsible for the privacy policies or practices of external third-party sites.
6. Global Privacy Rights (GDPR, CCPA / CPRA & UK GDPR)
We respect data privacy laws across the United States, European Economic Area (EEA), United Kingdom, Canada, and Australia. Under applicable privacy regulations, you are entitled to:
Right to Access & Know
Request verification of whether any personal information is maintained or processed.
Right to Erasure / Deletion
Request the complete deletion of any identifiable communications or inquiry logs.
Right to Non-Discrimination
Equal access and pricing to all tools regardless of whether privacy rights are exercised.
Opt-Out of Data Sale
We do not sell, barter, or monetize personal information to third parties.
Because we do not store customer profiles or linked accounts, most users maintain zero persistent data on our servers. If you have submitted an inquiry via our contact form and wish to request record deletion, email [email protected].
7. Children's Privacy (COPPA Compliance)
Our website is designed for trade professionals, engineering students, contractors, and adults. We do not knowingly collect or solicit personal information from children under the age of 13. If you believe a minor has submitted personal information through our contact form, please notify us immediately for prompt removal.
8. Data Security & Integrity
We implement industry-standard security safeguards to protect our digital infrastructure, including SSL/TLS 256-bit encryption for all web traffic, secure HTTPS endpoints, strict Content Security Policies (CSP), and automated intrusion prevention systems.
9. Policy Updates & Modifications
We reserve the right to revise this Privacy Policy periodically to reflect technological advancements, new tool additions, or statutory regulatory requirements. Any modifications will be posted directly to this page with an updated "Last Revised" date.
