 Secretive is an app for storing and managing SSH keys in the Secure Enclave. It is inspired by the [sekey project](https://github.com/sekey/sekey), but rewritten in Swift with no external dependencies and with a handy native management app.

 # Security Policy
 
+## Security Principles
+
+Secretive is designed with a few general tenets in mind:
+
+### It's Hard to Leak a Key Secretive Can't Read The Key Material
+
+Secretive only operates on hardware-backed keys. In general terms, this means that it should be _very_ hard for Secretive to have any sort of bug that causes a key to be shared, because Secretive can't access private key data even if it wants to.
+
+### Simplicity and Auditability
+
+Secretive won't expand to have every feature it could possibly have. Part of the goal of the app is that it is possible for consumers to reasonably audit the code, and that often means not implementing features that might be cool, but which would significantly inflate the size of the codebase.
+
+### Dependencies
+
+Both in support of the previous principle and to rule out supply chain attacks, Secretive does not rely on any third party dependencies. 
+
+There are limited exceptions to this, particularly in the build process, but the app itself does not depend on any third party code.
+
 ## Supported Versions
 
 The latest version on the [Releases page](https://github.com/maxgoedjen/secretive/releases) is the only currently supported version.
