As answered by people managing DevFinanceTools and SchoolRelay.
SchoolRelay's answer:
SchoolRelay uses a mobile first progressive web app to provide school updates without requiring parents to download software from an app store. The system includes automated privacy features that anonymize volunteer contact information 30 days after an event. It also synchronizes volunteer management with event scheduling, which ensures that volunteer slots are automatically removed if an event is cancelled.
SchoolRelay's answer:
SchoolRelay consolidates school communication into a single public hub, replacing fragmented channels like social media groups and email chains. It uses magic links for authentication to remove the need for password management. The platform also provides push notifications for urgent updates and includes a free tier that supports basic volunteer coordination and content publishing.
SchoolRelay's answer:
The primary audience includes school parent organizers and volunteers who need to manage campus communication. It also serves school families who use the public pages to find announcements, events, and sign up for volunteer shifts.
SchoolRelay's answer:
SchoolRelay was developed to solve the communication sprawl common in parent teacher organizations. It is designed to mirror the actual routines of school volunteers and parents, prioritizing clarity and scanability for users who are often checking updates on mobile devices in time sensitive situations.
SchoolRelay's answer:
SchoolRelay is built with React and Vite for the frontend experience. It uses Supabase for its backend infrastructure, which provides a PostgreSQL database, authentication services, and edge functions. The system runs on Node.js and uses Tailwind CSS for its interface design.
