Postern

Postern acts as a secure, self-hosted gateway connecting your personal data to various external applications. Key features include: * Unified data access for financial, health, calendar, email, contact, and home system information * No direct credential sharing with external applications * Local caching for rapid data retrieval * Granular access controls per data sector and application * Comprehensive auditing and logging of all data access This platform eliminates the need for complex custom integrations or sharing sensitive login details. By centralizing data access on your own hardware, Postern ensures that external applications receive only the specific information you've explicitly allowed, without ever handling your core credentials. Data is primarily served from a local cache, allowing for quick responses, while also enabling live fetches when necessary. Postern is designed for individuals and privacy-conscious users who want to leverage external services with their personal data while maintaining strict control and transparency. It provides a robust framework for managing what information is shared, with whom, and when, all from a secure, auditable hub on your local machine.
