Privacy Policy

1. Overview

Nano ("we", "us", "our") is a personalized AI chat companion. This policy explains what information we collect, how we use it, and the choices you have. We aim to be transparent and to keep your conversations private to your account.

2. Information We Collect

When you use Nano, we collect:

• Account data: your email address and name, used to identify your account.
• NanoCall phone number: if you optionally link a phone number, it is used for login and notifications. Verification codes are sent via the NanoCall service.
• Conversation data: your prompts, AI responses, and any files or images you upload, stored so you can revisit your history.
• Memory data: preferences and context you share, used to personalize future responses.
• Usage data: message counts, plan tier, feature usage, and API key usage, used to enforce plan limits and improve the service.
• Team project data: if you participate in a Business team project, your role, messages, and shared sources are visible to project members according to their role.
• Custom GPT data: instructions, actions, and OpenAPI schemas you configure for custom assistants.
• Payment data: processed by Stripe; we receive only confirmation of your subscription status, not your full card details.

3. How We Use Your Information

We use your data to:

• Provide, personalize, and maintain your chat experience.
• Process payments and manage your subscription through Stripe.
• Enforce usage limits and plan-specific features.
• Operate team projects, API keys, and custom GPTs.
• Respond to support requests and account questions.
• Detect, prevent, and address abuse or security issues.
• Improve model quality and service reliability over time.

4. How We Share Your Information

We do not sell your personal data. We share information only as needed to operate the service:

• AI providers: your prompts are sent to the AI models that generate responses, solely to return your reply.
• Stripe: handles payment processing under its own privacy policy.
• NanoCall: handles phone verification codes if you link a number.
• Service providers: hosting and infrastructure partners that help us run Nano.
• Team project members: messages and shared sources within a Business team project are visible to project members based on their role.
• Legal obligations: where required by law or to protect rights and safety.

Your private conversations are never browsed by admins. Admin tools focus on platform health — uptime, abuse prevention, and aggregate usage — not personal chat content. Team project content is visible only to members of that project, not to Nano admins.

5. Data Retention

Your conversations and memories remain on your account until you delete them. You can delete individual chats or your account at any time. When you delete content, it is removed from active access and eventually purged from backups. API keys remain active until you revoke or delete them. Account data is retained as needed to fulfill legal or operational obligations.

6. Your Privacy Choices

You can:

• Access and review your conversations and memories within the app.
• Delete individual chats or clear your memory entries at any time.
• Export your conversation history before deletion.
• Revoke or delete API keys from your settings.
• Unlink your NanoCall phone number from your account settings.
• Leave or delete team projects you own.
• Request full account deletion, which removes your associated data.
• Cancel your subscription at any time from the pricing page.

7. Security

We use reasonable technical and organizational measures to protect your data, including access controls and encrypted transmission. No system is perfectly secure, but we work to keep your information safe and to respond promptly to any incident.

8. Children's Privacy

Nano is not intended for children under 13 (or the minimum age in your region). We do not knowingly collect data from children. If you believe a child has provided us information, contact us and we will delete it.

9. International Users

Nano may be used from different regions. If you access the service from outside the country where it is operated, your data is transferred to and processed there. We take steps to ensure appropriate safeguards are in place for such transfers.

10. Changes to This Policy

We may update this Privacy Policy as the service evolves. We will notify users of material changes. Continued use of Nano after changes take effect means you accept the updated policy.
