Privacy Policy for Kepler
Last updated: December 20, 2025
1. Our Commitment to Your Privacy
Welcome to Kepler ("we," "our," or "us"). Your privacy is a top priority. This Privacy Policy explains what information we collect, how we use it, and how we protect it when you use our AI-powered knowledge engine (the "Service").
2. The Information We Collect
We collect two types of information:
A. Personal Information: This is the information needed to create and manage your account.
- Account Information: Your name and email address.
- Billing Information: When you subscribe, our payment processor (Stripe) collects your payment information. We do not store your full credit card details.
B. Your Content: This is the information you upload and generate within the Service.
- Uploaded Files: Any documents, videos, or audio files you add to your library.
- Added Links: URLs to articles, videos, or other web content you provide.
- Chat History: The questions you ask the AI and the answers it generates.
3. How We Use Your Information
We use your information for specific purposes:
- To Provide and Maintain the Service: We use Your Content to create your knowledge base, process your questions, and generate verifiable answers with citations. We use your Personal Information to manage your account and provide customer support.
- To Manage Your Subscription: To process payments, send invoices, and communicate with you about your account.
- To Improve Our Service: We may use anonymous, aggregated usage data to understand how our Service is being used and to make improvements. This data does not contain any of your personal information or content.
4. Your Content and AI Model Training
We will not use Your Content to train our AI models or any third-party AI models.
Your knowledge library, chat history, and uploaded files are yours alone. They are kept private and are never used to train external AI systems. The content you provide is sent to our AI partners only for the purpose of generating a response to your immediate query.
5. Data Sharing and Third-Party Services
We do not sell your data. We only share information with a few trusted third-party services (sub-processors) who help us operate our Service:
- Cloud Hosting (e.g., AWS, Cloudflare): For securely storing Your Content and running our application.
- Payment Processing (Stripe): To securely handle payments and manage subscriptions.
- AI Providers (e.g., OpenAI, Google, Anthropic): To process your queries and generate answers. We only send the necessary content from your selected sources to generate a response for that specific query.
6. Cookies and Analytics
We use essential cookies to make our site work, such as keeping you logged in. We may also use analytics tools to collect anonymous information about how our website is used to help us improve the user experience. You can control cookie preferences through your browser settings.
7. Security and Data Retention
We implement industry-standard security measures to protect your information. We retain your Personal Information and Your Content for as long as your account is active or as needed to fulfill our legal obligations. If you delete your account, we will permanently delete your associated data in accordance with our data retention policies.
8. Your Rights
You have the right to access, update, or delete your Personal Information at any time through your account settings. If you wish to permanently delete your account and all associated content, please contact us.
9. Changes to This Policy
We may update this Privacy Policy from time to time. We will notify you of any significant changes by updating the "Last updated" date on this page or by sending you an email.
