App name: WireSpan: Conduit Fill Calc (shown on your device as WireSpan)
Platform covered by this policy: iOS / iPadOS
This Privacy Policy explains how WireSpan (“the App”, “we”, “us”, or “our”) handles information when you use our mobile application on iOS or iPadOS.
WireSpan helps electricians and electrical professionals run reference calculations such as Ohm’s law, voltage drop, conductor sizing, conduit fill, box fill, and unit conversions. The App is a reference tool only. Always verify results against the applicable electrical code, local amendments, and the authority having jurisdiction.
We aim to collect only what is necessary to provide the App, keep your saved work available, verify purchases, and improve the product responsibly.
By using the App, you agree to this Privacy Policy. If you do not agree, please do not use the App.
| What | Examples | Stored where |
|---|---|---|
| Saved calculation history | Calculator type, custom name, input summary, result summary, formula/work text, favorite status, timestamps | On your device; may also sync to your private iCloud (CloudKit) container when iCloud is enabled |
| App preferences | Appearance (light/dark/system), preferred units (US/Metric), onboarding completion status | On your device only (not synced through our iCloud container) |
| PDF exports | PDF files you choose to generate from a calculation | Created temporarily on your device; shared only if you choose a destination through Apple’s share sheet (Mail, Files, AirDrop, etc.) |
| Purchase / entitlement status | Active subscription, lifetime unlock, trial eligibility, renewal status | Apple and RevenueCat; we do not receive your full payment card number |
The current version of WireSpan does not require you to create an account, and we do not ask for your name, email address, phone number, or password inside the App unless you voluntarily contact us for support by email.
| What | Purpose | Provider |
|---|---|---|
| Purchase history and entitlement status | Unlock Pro features and restore purchases | Apple App Store and RevenueCat |
| Anonymous user ID | Link purchase status to analytics and restore flows without a login | RevenueCat and PostHog |
| Device or installation ID | Distinguish app installs for analytics | PostHog |

The App Store release sends product analytics to PostHog. Development builds without a configured analytics key do not send PostHog events.
