S&T Exchanger Terms of Use

Effective August 29, 2026.

Engineering use

S&T Exchanger provides engineering calculation and documentation tools. Results depend on the entered process, fluid, geometry, method, and unit data. A qualified engineer must review the design basis, warnings, applicability limits, materials, mechanical design, fabrication requirements, and operating risks before results are used for procurement, fabrication, installation, or operation.

Subscription

S&T Exchanger Pro is an automatically renewing monthly subscription. The applicable store displays the localized price before purchase. Payment is charged to the store account at confirmation. The subscription renews unless canceled at least 24 hours before the current period ends. Manage or cancel the subscription in Google Play or App Store subscription settings.

Accounts and local files

Keep account credentials secure. Engineering projects, custom fluids, customer details, and generated files are currently stored locally. Maintain independent backups of engineering records that must be retained.

Platform terms

On Apple platforms, use is also governed by Apple’s Standard End User License Agreement. Store billing, refunds, and purchase records are governed by the applicable store.
