Concrete Calculator & Bags — Privacy Policy

Last updated: July 31, 2026

The short version

Concrete Calculator & Bags runs entirely on your iPhone. It has no accounts, no analytics, no advertising SDKs and no trackers. We collect no personal data.

What the app accesses

Nothing sensitive. Concrete Calculator & Bags needs no access to your photos, contacts, microphone or location. Every calculation runs on your device and works fully offline.

What we collect

Only what purchases require. The app itself sends us nothing — no analytics, no ads, no content uploads. Our App Store privacy label lists Purchase History only: when you buy Pro, our purchase partner RevenueCat processes the App Store receipt under a random anonymous identifier to unlock your features. It is not linked to your identity and is never used for tracking.

Purchases

Purchases are processed by Apple through the App Store — we never see your payment details. To validate purchases the app uses RevenueCat, which receives only a random anonymous identifier and the purchase receipt; no personal data, no tracking. Manage or cancel anytime in Settings → Apple Account → Subscriptions.
