Data Protection & Privacy

Privacy Policy & Client-Side Calculation Guarantee

We respect your privacy and design our tools to operate with minimal data collection. This policy outlines how technical information is handled when you visit PSI to GPM.

1. Client-side calculation processing (Zero Input Storage)

All pressure-to-flow calculations and engineering inputs entered on this website are processed locally in your web browser using client-side JavaScript. Input values, numerical dimensions, and calculation results are never transmitted to our servers, logged in server access files, or stored in any database.

2. Analytics and usage metrics

We use Google Analytics 4 (Measurement ID G-2KDW1RVCZ2) to measure aggregated website traffic, monitor page performance, and detect technical calculation errors. Google Analytics collects anonymized technical data such as browser type, operating system, approximate geographic region (city/country level), and page interaction paths. IP addresses are anonymized automatically by default.

We do not use tracking pixels for cross-site behavioral profiling, nor do we sell, trade, or transfer visitor data to commercial data brokers.

3. Cookie notice & consent mechanism

Under European (GDPR/ePrivacy), UK GDPR, and international privacy frameworks, we operate a conditional consent mechanism for non-essential cookies and analytics:

• Consent Management Platform: Upon your first visit, a consent preferences banner requests your affirmative permission before loading analytics or advertising scripts.
• Pre-Consent Protection: Non-essential tracking scripts (including gtag.js) and analytics cookies do not execute or load until you grant consent.
• Declining Cookies: If you decline or select "Essential Only", non-essential tracking scripts remain blocked.
• Managing & Revoking Choices: You can modify or withdraw your cookie consent preferences at any time by clearing your browser cookies/storage to re-prompt the banner, or by using the Google Analytics Opt-out Browser Add-on.

4. Third-party advertising & Google AdSense disclosures

This website may display advertisements served by third-party advertising vendors, including Google AdSense. In connection with these advertising services, please note the following:

• Third-Party Cookies: Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to this website or other websites across the Internet.
• Advertising Cookies: Google's use of advertising cookies enables it and its partners to serve ads to users based on their visits to this site and/or other sites on the Internet.
• Personalized Advertising Opt-Out: Users may opt out of personalized advertising by visiting Google Ads Settings. Alternatively, users can opt out of a third-party vendor's use of cookies for personalized advertising by visiting AboutAds.info Choices or the Network Advertising Initiative at NetworkAdvertising.org.
• EEA / UK / Swiss Visitors: In compliance with Google's EU User Consent Policy and the IAB Europe Transparency and Consent Framework (TCF v2.2), visitors from the European Economic Area, the United Kingdom, and Switzerland are presented with a Google-certified consent management interface to choose whether personalized or non-personalized advertising is served.

5. Contact form submissions

If you contact us through our contact form, your name, email address, and message content are transmitted securely to our form-processing provider (Web3Forms) solely to respond to your inquiry or review suggested formula corrections. Do not submit sensitive personal identifiers, confidential engineering plans, or proprietary intellectual property.
