How on-device processing works
BuildBrief Quick for Android
The Android Quick app uses Gemini Nano through Android AICore and the ML Kit Prompt API.
BuildBrief Quick for iPhone and iPad
The Apple Quick app uses Apple's Foundation Models framework and the system language model supplied with Apple Intelligence.
BuildBrief: Idea Teardown for Android
Idea Teardown uses Gemma 4 E2B through Google AI Edge LiteRT-LM. The model is delivered through Google Play Asset Delivery and runs locally after it is available on the device.
The BuildBrief apps do not request the Android Internet permission or contain a developer-operated network service for brief generation.
Storage, sharing, and export
Ideas and generated briefs are held in app memory while you use the apps. They are not saved to a developer account, database, analytics service, or cloud service.
If you choose a Share or Export action, the app opens a system interface and acts only after your selection. A file or message you create is stored or transmitted by the destination you choose and is then governed by that destination's privacy practices.
Data collection and tracking
The BuildBrief apps do not collect contact information, identifiers, usage data, diagnostics, location, purchases, or user content. They include no advertising, analytics, tracking, or telemetry SDKs. Marbatis Systems LLC does not sell or share app data because it does not receive app data.
Apple and Google platform services
Apple, Android, or Google Play may download, prepare, or update an on-device AI model independently of the BuildBrief apps. Marbatis Systems LLC does not receive personal information from those operating-system or store processes. Their handling of platform services and device diagnostics is governed by your settings and their policies.
Children
The BuildBrief apps are general-audience productivity tools and are not directed to children. Because the apps collect no data, they collect no personal information from children.
Changes and contact
If an app's data practices change, this policy and the relevant app-store disclosures will be updated before the changed version is distributed.
