Privacy policy.

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.

Browser extension

The Nucel Saver browser extension sends the address and title of a page to your Nucel account only when you ask it to: by clicking the toolbar icon, pressing the save shortcut, or clicking the Save to Nucel button it adds to posts and videos on X, Reddit, YouTube, Instagram, and Hacker News. On those five sites it reads only the link of the post or video next to the button, and nothing is sent until you click. It does not record your browsing history, read other pages, or run on other sites.

You sign in to the extension with your Nucel email and password. Your session token is kept in your browser's extension storage on your device, and it is removed when you sign out. What you save through the extension is then handled like any other save, as described in this policy.

Payments

Paid plans are processed by Dodo Payments, our merchant of record. We receive your email, name, payment status, and whatever the processor shares with us, such as the last four digits of your card. We never receive or store full card numbers. We keep billing records (plan, status, and payment history) for as long as needed to run your subscription and meet our accounting and legal obligations.

AI providers by plan

Depending on your plan, AI processing may use different providers or models.

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.
