Lucrum Pro does not request invasive storage permissions (READ_EXTERNAL_STORAGE or MANAGE_EXTERNAL_STORAGE).

3. Third-Party Services & Advertising (Google AdMob / UMP)
Non-Personalized Ads (npa=1)
All ad requests sent by Lucrum Pro enforce the npa=1 parameter. This instructs Google AdMob to serve only contextual ads and prohibits tracking across third-party apps or building personal behavioral profiles.

We integrate Google’s User Messaging Platform (UMP) compliant with the IAB TCF v2.2 framework (GDPR, LGPD).
Ad-Free Sanctuary for Pro Users
Subscribers and lifetime license holders enjoy an ad-free workspace with zero advertising SDK requests.

All financial transactions for subscriptions (Monthly, Annual) and one-time purchases (Lifetime) are handled and encrypted directly by the official Google Play Billing API.
Nowmadd Dev Studio never receives, views, or stores your credit card, banking, or billing credentials.
5. Diagnostics & Telemetry

7. User Data Control, Sovereignty & Deletion
Data Sovereignty
You have total control over your information. You can edit, export, or delete any client, quotation, or expense directly within the app at any time.

Complete Erasure upon Uninstall
Uninstalling Lucrum Pro or clearing app data in Android Settings immediately and permanently erases all local databases and cached documents from your device.
