Privacy Policy
Last updated: February 2026
1. Introduction
Nervia ("we," "our," or "us") operates the Nervia platform and related services, including the website and application (the "Service"). This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our Visual Intelligence Universe - including our 3D knowledge graph, neurons, clusters, and AI-powered features.
By using the Service, you agree to the collection and use of information in accordance with this policy. If you do not agree, please do not use the Service.
2. Information We Collect
Account and authentication
When you sign in via Google, GitHub, or Magic Link (email), we receive and store identifiers (e.g., email, name, profile picture) provided by the authentication provider. We use Supabase for authentication; their processing is subject to their privacy policy.
Content you create
We store the content you create in Nervia: neurons (notes, sources, ideas), connections, clusters, tags, and any text or metadata you add. This data is stored to provide the Service and to power features such as the Neural Core (AI) and auto-clustering. We do not use your content to train third-party AI models for purposes unrelated to your use of the Service.
Usage and technical data
We may collect usage data (e.g., feature usage, session duration) and technical data (e.g., browser type, IP address, device information) to operate, secure, and improve the Service. If you use the Nervia browser extension, we may process data necessary to sync bookmarks or saved items to your graph.
3. How We Use Your Information
We use the information we collect to:
- Provide, maintain, and improve the Service
- Authenticate you and manage your account
- Power the 3D graph, AI (RAG), and clustering features
- Send you service-related communications (e.g., magic link emails)
- Respond to support requests and enforce our terms
- Comply with legal obligations and protect our rights
4. Sharing and Disclosure
We do not sell your personal information. We may share data with:
- Service providers (e.g., Supabase, hosting) who process data on our behalf under strict agreements
- Legal authorities when required by law or to protect our rights and safety
- Other users only when you explicitly share content (e.g., publishing a cluster as a shared 3D world)
5. Data Retention and Security
We retain your account and content for as long as your account is active or as needed to provide the Service. You may request deletion of your account and associated data; we will process such requests in accordance with applicable law.
We implement appropriate technical and organizational measures to protect your data. No method of transmission or storage is 100% secure; we cannot guarantee absolute security.
6. Your Rights
Depending on your jurisdiction, you may have the right to access, correct, delete, or port your personal data, or to object to or restrict certain processing. To exercise these rights, contact us using the details below. You may also have the right to lodge a complaint with a supervisory authority.
7. Children
The Service is not directed at children under 13 (or the applicable age in your region). We do not knowingly collect personal information from children.
8. Changes
We may update this Privacy Policy from time to time. We will post the updated version on this page and update the "Last updated" date. Continued use of the Service after changes constitutes acceptance of the revised policy.
