Privacy Policy for Sentinel
Overview
Sentinel is designed with a simple principle: your conversations and personal context stay on your device. We built Sentinel to be private by default, with no hidden data collection.
Data We Collect
We do not collect any personal data. Sentinel does not collect, store, transmit, or sell user information to Sentinal Prime Inc. or any third party.
There is no account system, no sign-in, and no user profile on our servers because we do not run a user data backend for the app.
How Your AI Works
Sentinel's AI model runs locally on your phone. Your messages and AI conversations are processed on-device and do not leave your device as part of the core assistant experience.
Memory System
Sentinel's memory features (including saved facts and behavioral portrait data) are stored exclusively on your device using local SQLite and AsyncStorage. This memory is never synced to Sentinal Prime Inc. servers and is never transmitted to third parties.
Web Search
If you use real-time web search features, Sentinel may send query text to third-party endpoints only to retrieve current information. These services may include wttr.in, Yahoo Finance, DuckDuckGo, ESPN, and CoinGecko.
Requests are sent without user account identity from Sentinal Prime Inc. because no account exists. Sentinel does not attach profile-level identifiers for tracking users across services.
Third Party Services
Sentinel does not use third-party analytics SDKs, advertising SDKs, tracking pixels, or cookies. We do not run analytics for user behavior in the app.
Children's Privacy
Sentinel is not designed to collect personal information from anyone, including children under 13, because the app does not collect personal data at all.
Changes to This Policy
If this policy changes, we will update this page and revise the effective date above. Any future changes will continue to reflect our privacy-first approach in plain language.
This policy is governed by the laws of the United States.

Because we collect no user data, there is no retained user dataset to access, export, or delete. You can remove all local app data at any time by deleting the Sentinel app from your device.
