Denken Box

Denken Box is a personal-knowledge client for Supabase. Capture what matters, organize it your way, and keep it in a database you control. WHY DENKEN BOX Most knowledge apps lock your notes inside their servers. Denken Box flips the model: you bring your own Supabase project, and the app becomes a fast, native iOS client over the database you already own. Your notes, decisions, projects, conversations, and references live on your infrastructure — not ours. WHAT YOU CAN CAPTURE • Memories — quick notes, ideas, and observations • Decisions — what you decided, why, and the context behind it • Projects — active work threads with status and notes • Conversations — meeting takeaways and important threads • Reference items — articles, links, snippets worth keeping FEATURES • Native SwiftUI iOS app — fast, fluid, made for iPhone and iPad • Bring your own Supabase project (URL + anon key) — full control • Face ID / Touch ID lock for sensitive entries • Offline-first — capture without a connection, sync when you're back • Per-project switching — keep work and personal knowledge separate • Try with Demo — explore the app with sample data before connecting WHO IT'S FOR Knowledge workers, founders, researchers, students, and anyone who already uses Supabase (or wants an excuse to). If you've ever wished your notes lived in a real database instead of a proprietary app, Denken Box is built for you. PRIVACY Denken Box doesn't operate servers that store your data. Your notes go directly from your device to your Supabase project. No analytics, no telemetry, no tracking, no advertising SDKs. The only third-party service Denken Box communicates with is the Supabase project you configure. See the full privacy policy at the URL above. REQUIRES A Supabase project (free tier works) with the Denken Box schema. The in-app Setup Guide walks you through every step, or paste the bootstrap prompt into ChatGPT/Claude to have it generated for you. "Denken" is German for "to think." Denken Box is your thinking box.
