Effective Date: April 9, 2026
We believe that efficiency and productivity shouldn't come at the cost of your privacy. This policy explains how information is handled when you use the Cutting Plan Optimizer mobile application (the "Services"). Cutting Plan Optimizer is developed and managed by Gerhard Kienzler ("I", "we," "us," or "our").
Because this is a primarily offline application, we do not operate our own servers or databases to collect or store your personal data. However, the app integrates necessary third-party services to provide backups, analytics, advertising, and subscription management.
To provide a reliable and optimized experience, data collection is limited to local processing and essential third-party integrations:
Information Processed Locally or via Third Parties
User Content & Project Data: The cutting plans, dimensions, and projects you create are stored entirely locally on your device. We do not have access to this data.
Cloud Backups (Optional): If you choose to enable backups, your project data is synced directly to your personal Google Drive account. We do not intercept, store, or have access to these backups on any external servers.
Subscription Data: If you purchase premium features, our payment processor (RevenueCat) and the respective app stores (Apple/Google) collect purchase history to manage your access.
Information Collected Automatically (via Third-Party SDKs)
Analytics Data: We use Google Analytics to collect anonymous usage data (e.g., app launches, feature usage, crash reports) to help us understand how the app is used and improve its functionality.
Advertising Data: We use Google AdMob to display advertisements. AdMob may collect device identifiers (such as the Apple IDFA or Google Advertising ID), IP addresses, and usage data to serve personalized or non-personalized ads based on your device settings.
Since we do not store your data ourselves, the integrated services use your information for the following specific purposes:
Core Functionality: To process your cutting optimizations locally on your device.
Data Safety: To allow you to backup and restore your projects via your own Google Drive.
App Improvements: To monitor app stability, catch bugs, and analyze anonymous usage trends via Google Analytics.
Monetization: To display relevant advertisements through AdMob and process in-app purchases or subscriptions via RevenueCat.
We do not collect, hold, or sell your personal data. Your data only interacts with the following essential third-party services:
Google Drive: Used exclusively if you opt-in to cloud backups. Data is transmitted directly between your device and Google's servers.
Google AdMob: Used to serve advertisements within the app.
Google Analytics for Firebase: Used to collect crash reports and anonymous usage statistics.
RevenueCat: Used to process and manage your in-app purchases and subscriptions.
Apple / Google: Used for app store authentication and processing payments securely.
If you are located in the European Economic Area (EEA), you have rights regarding your personal data. Because we do not store your data on our servers, exercising these rights is mostly done directly on your device:
Access, Correction & Erasure: All your project data can be viewed, edited, or deleted directly within the app. Deleting the app clears all local data. You can delete your cloud backups directly within your Google Drive account.
Objection & Opt-Out (Ads/Analytics): You can opt-out of personalized advertising and analytics tracking using your device's system settings (e.g., "Limit Ad Tracking" on iOS or "Opt out of Ads Personalization" on Android). Consent for analytics and personalized ads can also be managed via the app's consent dialog (CMP) presented upon first launch.
Local Storage: Your projects and cutting plans reside securely on your own device.
Data in Transit: When the app communicates with third-party services (like saving a backup to Google Drive or verifying a purchase via RevenueCat), industry-standard encryption (HTTPS/TLS) is used.
No Developer Access: We have designed the app so that we physically cannot access your projects, backups, or personal identity.
Local Data: Kept on your device until you delete the app or clear the app's data.
Backups: Kept in your Google Drive until you manually delete them.
Third-Party Data: Data handled by AdMob, Google Analytics, and RevenueCat is retained according to their respective privacy policies.
We may update this policy as Cutting Plan Optimizer evolves or as we add new integrations. We will notify you of any significant changes via an update note in the App Store/Google Play or an in-app notification.
