Privacy Policy
Last updated: May 2026
Overview
Welding Reference Pro ("the app") is developed by Zima Logistics. We believe the best privacy policy is a simple one: we collect as little data as possible and we never sell your information to anyone.
What We Collect
Data stored on your device
All calculator inputs and saved calculations are stored locally on your iPhone using SwiftData. This data never leaves your device and is not transmitted to any server.
Analytics
The app uses Apple's standard analytics framework (App Store Connect Analytics). This data is anonymized and aggregated by Apple before we see it. We receive no personally identifiable information.
Crash reports
If the app crashes, Apple may collect an anonymized crash report. We use this information solely to fix bugs. No personal information is included in these reports.
What We Do Not Collect
- Name, email address, or any contact information
- Location data
- Device identifiers beyond what Apple provides for App Store Analytics
- In-app usage details tied to your identity
- Payment information (handled entirely by Apple)
In-App Purchases
Welding Reference Pro offers a one-time Pro in-app purchase. All payment processing is handled by Apple through the App Store. We never see or store your payment information.
Third-Party Services
The app does not integrate with any third-party analytics, advertising, or tracking services. There are no third-party SDKs included in the app that collect personal data.
Children's Privacy
Welding Reference Pro is not directed at children under 13. We do not knowingly collect personal information from children.
Changes to This Policy
If we change this privacy policy, we will update the date at the top of this page. Material changes will be noted in the app's update release notes.
This website (welding-ref.zima-logistics.com)
This marketing website — separate from the app — uses Google Analytics 4 to understand aggregate traffic (page views, referrers, and which links are clicked, such as the App Store button). This helps us measure which content is effective. Google Analytics sets cookies and processes data per Google's privacy policy. The data is aggregated and not used to identify you personally. This applies only to the website; the Welding Reference Pro app itself still collects nothing and makes no network calls. You can opt out using Google's opt-out browser add-on or any content blocker.
