Learn about third-party services, your privacy rights, and how to request data deletion. Noesis is built on the belief that your research, conversations, and ideas belong to you. Understanding what data we collect, how we use it, where it's stored, and what rights you have is a core part of that promise. This page explains our data practices in plain language — who handles your data, how it stays secure, and exactly how to exercise your privacy rights. For the complete legal text, see the full [Noesis Privacy Policy](https://thinknoesis.xyz/privacy). This page is a plain-language summary of our data practices. For the full legal text, including all applicable rights and obligations, please read the [Noesis Privacy Policy](https://thinknoesis.xyz/privacy). *** ## What Data Noesis Collects When you create a Noesis account, we collect the following information through **Clerk**, our authentication provider: * **Name** — your display name as provided during sign-up or synced from your OAuth provider. * **Email address** — used for account communication, billing receipts, and security alerts. * **Profile picture** — synced from your account with your authentication provider, or set during sign-up. This information is stored securely and used solely to identify you within the platform, personalize your experience, and enable collaboration features like shared Spaces. Everything you create inside Noesis — your conversations, branching structures, chat sessions, Spaces, and concept maps — is stored as **usage data** associated with your account. Specifically: * **Conversations and messages** are stored so you can return to them, branch from them, and view them on your concept map at any time. * **Branching structures** capture the full tree of your exploration paths, including alternate branches you created by forking at any message. * **Spaces and projects** organize your work across sessions and are preserved until you choose to delete them. Your conversation content is sent to third-party **AI model providers** (OpenAI, Anthropic, Google, xAI) in real time to generate responses. These providers process your messages according to their own data retention and usage policies. We encourage you to review their policies if you handle sensitive information. We also use aggregated, anonymized usage data to improve the performance and quality of the Noesis service. Noesis integrates with a carefully selected set of third-party services, each serving a specific role: | Service | Purpose | Data Shared | | ---------------------------------- | --------------------------------------- | -------------------------------------------------------------- | | **Clerk** | Authentication and user management | Name, email, profile picture | | **Convex** | Backend data storage and real-time sync | All workspace data (conversations, branches, spaces) | | **OpenAI, Anthropic, Google, xAI** | AI model inference | Your conversation messages | | **Stripe** | Payment processing and billing | Payment card details (Noesis never stores card data directly) | | **Vercel Analytics** | Anonymous usage analytics | Browser type, device info, IP address (aggregated, no cookies) | Each of these services maintains its own privacy policy. We recommend reviewing them — particularly those of the AI model providers if you work with sensitive research material. You can request full deletion of your account and all associated data at any time. **To delete your account from within Noesis:** 1. Click your **avatar** (top-right) and select **Settings**. 2. Navigate to **Data & Privacy**. 3. Scroll to the **Danger Zone** section and click **Delete My Account**. 4. Confirm by entering your account email address, then click **Permanently Delete Account**. Your account is immediately deactivated and your data is queued for permanent deletion from our systems, including all conversations, branches, spaces, and concept maps. **To request deletion by email:** Send a deletion request to [support@thinknoesis.xyz](mailto:support@thinknoesis.xyz) from the email address associated with your account. Include "Account Deletion Request" in the subject line. We will process your request and confirm deletion. **Important:** Deletion is permanent and irreversible. Export your data before proceeding — see [Export Your Data](/account/settings#data-management) for instructions. *** ## How Your Data Is Used Noesis uses the data we collect for the following purposes: * **To provide the service** — your account data, conversations, and workspace content are the foundation of everything Noesis does. * **To process AI responses** — your messages are sent to AI model providers in real time to generate the responses you see. * **To improve Noesis** — anonymized, aggregated usage patterns help us identify bugs, prioritize features, and improve performance. * **To communicate with you** — we use your email address to send billing receipts, security alerts, and (if you opt in) product announcements. * **To detect and prevent issues** — technical data like IP address and browser type helps us identify abuse, investigate errors, and maintain service security. Your conversation content is used only to generate responses through our AI model providers and to maintain your workspace. We use aggregated, anonymized usage data — not your personal conversation content — to improve the performance and quality of the service. *** ## Data Storage and Security Your workspace data is stored with **Convex**, a modern backend platform that provides: * **Encryption at rest** — all stored data is encrypted using industry-standard algorithms. * **Encryption in transit** — all data transferred between your browser and Noesis servers uses TLS (HTTPS). * **Real-time sync** — Convex enables live collaboration features while maintaining data integrity across devices and sessions. We implement industry-standard security measures throughout our infrastructure. However, no system connected to the internet can guarantee absolute security. If you believe your account has been compromised, contact [support@thinknoesis.xyz](mailto:support@thinknoesis.xyz) immediately and revoke active sessions in **Settings → Security**. *** ## Cookies Noesis uses only **essential cookies** — the minimum required for authentication and session management. We do not use: * Advertising cookies * Cross-site tracking cookies * Third-party profiling cookies **Vercel Analytics** collects anonymous, aggregated usage data without using any cookies. This means your browsing behavior on Noesis is not tracked across other websites. *** ## Your Privacy Rights You have the following rights with respect to your personal data: Request a summary of the personal data Noesis holds about you by emailing [support@thinknoesis.xyz](mailto:support@thinknoesis.xyz). Download a full export of your conversations, branches, and spaces from **Settings → Data & Privacy → Export My Data**. Permanently delete your account and all associated data from **Settings → Data & Privacy**, or by emailing support. Contact [support@thinknoesis.xyz](mailto:support@thinknoesis.xyz) to opt out of non-essential data collection. Note that essential session data cannot be disabled. *** ## Exercising Your Rights To exercise any of your privacy rights — including data access, correction, export, deletion, or opting out of non-essential data collection — contact us at: **[support@thinknoesis.xyz](mailto:support@thinknoesis.xyz)** Please include your account email address and a description of your request. We aim to respond to all privacy requests within 5 business days.
