Privacy Policy

nnuer ("we") is a community and library for UI blocks made with AI, kept together with the prompt that builds them. This policy explains what we collect when you use nnuer.site and the nnuer connector for AI tools (MCP), why, and how long we keep it.

What we collect

• Account: email address, display name, profile handle and bio. With Google sign-in, the name, email and profile picture Google shares. Accounts issued by the operator have a password, stored only as a hash.
• Content you save: blocks (title, description, tags, category, build prompt, result code), images and videos you upload, reproductions, studio settings (cover, colours, links, featured blocks).
• Activity: bookmarks, follows and reports you make.
• Sign-in sessions: a session cookie, and the IP address and browser user agent recorded with each session.
• Connected AI tools: when you connect a tool such as Claude, we store its name, the permissions you allowed and the OAuth tokens issued to it.

What the AI connector receives

The connector only receives what an AI tool sends when it calls one of nnuer's tools: blocks you ask it to submit (prompt, code, images), search words and block ids. It does not read your conversations, chat history, memory or files in the AI tool. Submitted blocks wait in your review inbox and are saved only when you choose to save them. Search words are used to answer the request and are not stored.

How we use it

• To run the service: sign-in, saving and showing blocks, previews, search, following and bookmarks.
• To show public blocks and profiles to others, as you choose per block (private, link only, public).
• To keep the service safe: rate limits, handling reports and hiding content that breaks the rules.

We do not sell personal data, show ads, or use third-party analytics or tracking.

Who processes it

• Vercel: hosting and request logs.
• Neon: the database.
• Cloudflare: storage for uploaded files (R2), and screenshots of block previews for card thumbnails (Browser Rendering).
• Google: sign-in, only if you choose Google sign-in.

How long we keep it

• Account, blocks and activity: until you delete them or your account is deleted.
• Blocks sent by an AI tool: kept in the review inbox until you finish the review. Then the unsaved blocks and their uploaded images are deleted.
• Sessions expire after 7 days of inactivity. Connector access tokens last 1 hour and refresh tokens 30 days. Disconnecting a tool in Settings deletes its tokens immediately.

Your choices and rights

• Change your profile, block visibility or studio in Settings; delete any block or result you made.
• Disconnect AI tools any time in Settings > AI tool connections.
• To see, correct or delete your data, or to delete your account, contact us at nnuer.site@gmail.com. We respond within 30 days.

Children

nnuer is not meant for children under 14, and we do not knowingly collect their data.
