Data Collection and Processing
We are committed to protecting your privacy. This calculator
operates with a strict no-data-collection policy:
-
No Server Uploads: All PDF processing happens
entirely in your browser using client-side JavaScript
-
No Data Storage: Your academic data, PDFs, and
calculation results are never saved or stored anywhere
-
No Analytics: We do not use Google Analytics,
tracking pixels, or any user behavior monitoring tools
-
No Third-Party Services: Your data never leaves
your device or gets sent to external services
Local Storage & Technical Implementation
The only data we store locally on your device is:
-
Theme Preference: Whether you prefer light or
dark mode (stored in browser localStorage)
-
Session Data: Temporary PDF extraction results
during your session (automatically cleared when you close the
browser)
Our privacy-first approach is built into the application architecture:
-
Client-Side Processing: PDF.js library
processes documents entirely in your browser
-
No Network Requests: Apart from loading the
application itself, no data is transmitted over the internet
-
Static Hosting: The application is hosted as
static files with no server-side processing
-
Open Source: All code is transparent and can be
audited on GitHub
Data Security
Your academic information remains secure because:
-
No Data Transmission: Your PDFs and grades
never leave your device
-
Browser Security: Modern browser sandboxing
protects your data from external access
-
No Cookies: We don't use tracking cookies or
persistent identifiers
-
HTTPS Only: All connections are encrypted and
secure
Bottom Line: Your academic data is completely
private, secure, and never leaves your device. We have no access
to your PDFs, grades, or personal information.
