What we store

Nucel stores the content you deliberately save (links, extracted text, media references), the AI-generated summaries, tags, and embeddings derived from it, your collections and chat history, your email address and profile name, and — if you enable notifications — device push tokens. Nothing is collected passively from your browsing.

How your data is processed

Saved content is sent to third-party AI providers (Google Gemini, Anthropic, or OpenAI, depending on configuration) to generate summaries, tags, and search embeddings. Data is stored in Supabase (PostgreSQL) and queued through Upstash Redis. Weekly digest emails are delivered through Resend. If analytics or error monitoring are enabled, product events go to PostHog and errors to Sentry.

Your rights

Your knowledge base is yours. From Settings you can export everything as JSON or CSV at any time, and delete your account — deletion is immediate and removes every item, collection, chat, digest, and device record permanently.
