Slab — Privacy Policy

Last updated: October 25, 2026.

Slab (“the app”) is a fully offline concrete & masonry material estimator. We do not collect, store, transmit, sell, or share any personal data.

What we collect: nothing

• No account and no sign-up are required.
• No analytics, no tracking, no advertising identifiers, no third-party SDKs.
• The app makes no network requests and works entirely offline.
• All content you create (projects, dimensions, costs, settings) is stored only on your device and can be deleted by you at any time.

Because the app performs no data collection, its App Store privacy label is “Data Not Collected.”

Purchase

Slab is a paid app bought through Apple's App Store; it has no in-app purchases. Apple processes the payment, and we never see or receive your payment information.
