Privacy Policy

Effective Date: September 13, 2026· PharmaChemEng Engineering Platform

At PharmaChemEng (accessible from pharmachemeng.com), accessible worldwide for pharmaceutical chemical engineers, process designers, and validation professionals, protecting your privacy and engineering data integrity is our utmost priority.

This Privacy Policy document outlines the types of personal data, calculation session inputs, and technical metrics collected, recorded, and stored by PharmaChemEng, as well as how we safeguard that data.

1. Information We Collect

We collect information to provide better engineering calculations, personalized equipment sizing reports, and secure user account authentication:

Account Credentials: When you register for an account, we collect your full name, email address, password hash, and optional technical background info (e.g. Process Engineer, Validation Manager, Consultant).
Technical Calculation Session Inputs: Parameters submitted into our engineering calculators (e.g., vessel diameter, design pressure, heat transfer coefficients, flow rates) are processed client-side or stored temporarily in your local session to generate CAD schematics and datasheets.
Technical Newsletter Subscriptions: Email addresses provided via our technical digest signup form to receive cGMP guides, scale-up models, and software updates.
Log Data & Device Identifiers: IP addresses, browser type, operating system, standard web log information, and page performance analytics.

2. How We Use Your Information

The information we collect is strictly used for engineering and operational purposes:

To deliver, execute, and display live parametric CAD vector graphics and PDF datasheet reports.
To manage user authentication, session security, and account verification.
To maintain calculator usage statistics and optimize performance for high-traffic engineering tools.
To send technical engineering updates and newsletters (you may opt out at any time).
To protect against security threats, unauthorized access, and automated abuse.

3. Calculation Confidentiality & Data Protection

We recognize that process design parameters (reactor volumes, heat exchanger sizing, batch scale-up factors) are proprietary to your engineering projects:

Proprietary Engineering Data Guarantee:

PharmaChemEng does NOT sell, trade, rent, or commercialize your project calculation inputs or proprietary design parameters to any third-party advertisers or external organizations.

4. Cookies & Local Storage

PharmaChemEng uses standard cookies and browser local storage to maintain user preferences and active session states:

Authentication Cookies: Secure session tokens to keep you logged in across tools.
CAD Viewport Theme Preference: Remembers your choice between Dark Blueprint mode and Light CAD print mode.
Transient Calculator State: Caches active input variables locally so work is preserved across tab navigation.

5. User Data Rights (GDPR & Privacy Compliance)

Depending on your location, you hold the following rights regarding your personal data:

Right to Access: Request copies of the personal data held under your account.
Right to Rectification: Request correction of inaccurate account details.
