Concrete Apps Privacy Policy
Last Updated: January 6, 2026

Concrete Apps (including Concrete Buddy and Concrete Calculator, “the Apps”) is committed to protecting your privacy. This Privacy Policy explains how we collect, use, share, and protect information when you use our Apps on Android (Google Play Store) or iOS (Apple App Store). By using the Apps, you agree to the terms outlined in this policy.

No Personal Data Collected by Us
We do not collect or store personal information such as names, email addresses, or other personally identifiable information, except for data you voluntarily input into the Apps (e.g., project measurements, notes, company/client details if a feature asks for them).
This data is stored locally on your device and is not transmitted to us.

In-App Purchases


Some Apps offer optional in-app purchases (for example, a one-time “Ad-Free / Pro” purchase in Concrete Calculator to remove ads permanently).
All transactions are processed securely through Google Play or the Apple App Store.
We do not receive or store any payment information. All billing details are handled by Google and Apple according to their respective privacy and security policies.
We may store a simple purchase status (for example, “Ad-Free enabled”) locally on your device so the App can unlock features and disable ads.
You may be able to restore purchases through the store (especially on iOS). If you uninstall the App, locally stored app data may be removed from your device.

Image Picker / PDF Images (Concrete Buddy or any App feature that generates PDFs)
If an App includes a PDF or document feature, you may select images from your device.
These images remain on your device unless you choose to share/export them. They are not collected, transmitted, or stored by us.

Third-Party Advertising (Google AdMob and Unity Ads)


Some Apps may use Google AdMob and/or Unity Ads to display banner, interstitial, and rewarded ads.
These services may collect information such as:
Device identifiers (e.g., Android Advertising ID or Apple’s Identifier for Advertisers [IDFA], if permitted)
Ad interaction data (e.g., ad clicks, impressions, reward events)
Approximate location (inferred from IP address, if enabled by your device settings)
Analytics and device/app data to help deliver and measure ads

Unity’s Privacy Policy: https://unity.com/legal/privacy-policy

App Tracking Transparency (iOS)
On iOS, you can allow or deny tracking when prompted. If you deny tracking, ads may be less personalized.

Game Feature & Firebase Leaderboard (if enabled in an App)
Some Apps may include an optional game/leaderboard feature that uses Firebase to store and manage leaderboard data. When you use a leaderboard feature, the following information may be collected:
The score you achieve
The username or nickname you choose to enter
This information is used only for displaying rankings on the leaderboard and maintaining game functionality. No sensitive personal data is required. The username you enter is optional and does not need to be your real name.
Firebase may process this data in accordance with its privacy practices. For more details, see:
Google’s Privacy Policy: https://policies.google.com/privacy

YouTube Help Content
The Apps may link to or embed YouTube videos for educational purposes.
YouTube/Google may collect viewing data when you access this content. For details, see:
YouTube / Google Privacy Policy: https://policies.google.com/privacy

Future Cloud Features (not currently active)
At this time, we do not operate a user account system for these Apps and we do not store your project data on our servers. If we add optional cloud saving (for example, saving invoices) or backend services in the future, we will update this Privacy Policy before or at the time those features are released.
