RayCrest Lab Calculator stores saved recipes, compounds, and preferences locally on your device. The app does not include analytics, advertising SDKs, or tracking frameworks.
Optional online compound lookup may send the search term you enter to third-party public chemistry services such as PubChem to retrieve compound information. RayCrest does not use this lookup to identify you, track you, or build a profile. You can use the app's calculators manually without online lookup.

If you contact RayCrest for support, we may receive your email address and the information you include in your message, such as screenshots, calculation details, device model, iOS or iPadOS version, and app version. We use support information to respond to your request, troubleshoot issues, and improve the product.
Please avoid sending confidential lab, patient, clinical, or regulated information in support messages unless it is necessary for the support request and you are comfortable sharing it with RayCrest Software.
You can delete saved items inside the app where available. Removing the app from your device removes the app's local container data from that device.
