Cryogenics Pro Privacy Policy

Last Updated: [2026-1-1]

Introduction
Cryogenics Pro ("the App") is a simple reference tool for cryogenics-related calculations and scientific data. We do not collect, store, or transmit any personal information from users. This policy explains our commitment to user privacy.
Data We Do NOT Collect
The App does not collect or share any of the following:

User names, email addresses, or phone numbers
Location data (GPS, Wi-Fi, cellular)
Device identifiers (e.g., UDID, IMEI, MAC address)
Photos, contacts, or calendar data
Usage analytics, crash reports, or behavioral data
Any data from third-party services (e.g., social media, ads, analytics SDKs)

Why This Policy Exists
Apple requires all apps to disclose data practices in the App Store. Since Cryogenics Pro does not collect any user data, this policy confirms compliance with Apple’s guidelines.
Open Source Libraries
The App uses open-source libraries (e.g., Swift, Foundation, UIKit) for core functionality. These libraries:

Do not collect user data
Are used strictly for app functionality (no tracking, ads, or analytics)
Are audited for privacy compliance (see Apple’s Privacy Manifesto)
