Privacy Policy
Last Updated: November 26, 2025
Welcome to nosystem.chat, a service provided by November LLC ("we," "our," or "us"). We are committed to protecting your privacy and ensuring transparency about how we handle your data.
By using nosystem.chat, you agree to the collection and use of information in accordance with this policy.
1. Information We Collect
A. Personal Information
When you create an account, we collect:
- Identity Data: Name, email address, and profile image (via your authentication provider).
- Billing Data: Transaction history and subscription status. Note: We do not store credit card details. All payment processing is handled securely by Polar.sh (Merchant of Record) and Stripe.
B. Usage Data
We collect data on how you interact with the Service:
- Chat Content: We store the contents of your conversations (user prompts, system prompts, and AI responses) to provide the service and strictly maintain your chat history.
- Technical Data: IP address, browser type, device information, and timestamps.
- Telemetry: We use PostHog to track anonymized usage patterns to improve the platform performance.
2. How We Use Your Data
We use your data solely for the following purposes:
- Providing the Service: To authenticate you, process your API requests, and persist your chat history.
- Billing: To calculate usage (token counting) and process payments via Polar.sh.
- Communication: To send transactional emails (receipts, password resets) or legal notices.
We do not sell your personal data. We do not use your chat content to train our own artificial intelligence models.
3. Data Sharing and Subprocessors
To provide nosystem.chat, we transmit specific data to trusted third-party service providers. By using our service, you acknowledge and agree to data transfer to the following entities:
| Provider | Purpose | Data Shared | Privacy Policy |
|---|---|---|---|
| Vercel | Hosting & AI Gateway | IP address, Request metadata, Transient request content | Link |
| PlanetScale | Database Storage | User account data, Encrypted chat history | Link |
| Polar.sh / Stripe | Billing & Payments | Email, Payment ID, Usage metrics | Link |
| PostHog | Analytics | Anonymized usage data, Device info | Link |
| AI Model Providers | Generating Responses | Your raw prompts and system instructions | Check each provider |

Important Note on AI Providers: When you select a specific model (e.g., from OpenAI, Anthropic, or Google), your prompt and system instructions are sent directly to that provider's API. Your data is then subject to that specific provider's API data usage policies. Most providers do not use API data for training, but you should verify this with the specific provider you choose to use.
4. Data Retention and Deletion
- Retention: We store your account information and chat history indefinitely to provide consistent service until you choose to remove it.
- Deletion: You may delete your account and all associated data at any time via the user settings page. Upon deletion, your data is permanently removed from our active database. Note that some data may persist in encrypted backups for a limited period (typically 30 days) before being completely overwritten.
5. Security
We implement industry-standard security measures to protect your data, including encryption in transit (HTTPS) and encryption at rest where applicable. However, no method of transmission over the Internet is 100% secure, and we cannot guarantee absolute security.
6. Children's Privacy
Our Service is intended for users aged 13 and older. We do not knowingly collect personal identifiable information from children under 13. If we discover a child under 13 has provided us with personal information, we will immediately delete such information.
7. Changes to This Policy
We may update our Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page and updating the "Last Updated" date.
