Privacy Policy
Last Updated: September 8, 2025
Your privacy is important to us. This Privacy Policy explains how Yu Ong ("we," "us," or "our") collects, uses, and protects your information when you use the Sheetknow Google Sheets Add-on and our website, `http://sheetknow.com` (the "Service").
1. Information We Collect
- Personal Information: When you sign up for an account using Google Authentication, we collect your name and email address from your Google profile. We use this information to create and manage your account, communicate with you, and provide customer support.
- Account & Usage Data: We store your unique API key and your current credit balance in our database to operate the Service. We also collect data on your credit consumption for billing and service analytics.
- Payment Information: We use Stripe as our third-party payment processor. When you purchase credits, you provide your payment information directly to Stripe. We do not collect, see, or store your credit card number or other sensitive payment details. We only receive a confirmation from Stripe that your payment was successful. We encourage you to review Stripe’s Privacy Policy.
2. How We Process Your Prompts (Your Data)
This is a critical part of our service, and we want to be completely transparent about the data flow.
When you run a prompt in Google Sheets, the text content of that prompt is sent securely from the Add-on to our backend server, which is hosted on Google Cloud Platform. Our server immediately forwards this prompt to Google's Generative AI (Gemini) API for processing. Once the AI generates a response, it is sent back to our server. Our server instantly relays this response back to your Google Sheet.
Crucially, we do not store or log the content of your prompts or the AI-generated responses on our servers. The data is processed ephemerally—it passes through our system solely for the purpose of getting a response from the AI and returning it to you.
3. How We Use Your Information
We use the information we collect for the following purposes:
- To provide, maintain, and improve the Service.
- To create and manage your account and process your credit purchases.
- To communicate with you about your account, updates, and support requests.
- To ensure the security and integrity of our Service.
4. Third-Party Services
We rely on trusted third-party services to provide our Service:
- Google Cloud Platform & Firebase: Our backend infrastructure, including our server and Firestore database (for storing account info like your email, API key, and credit balance), is hosted on Google Cloud.
- Google Authentication: Used for secure sign-up and login.
- Google Generative AI (Gemini): The AI service that processes your prompts. Your prompts are subject to Google's AI policies.
- Stripe: Our payment processor for handling credit purchases securely.
5. Data Security
We implement industry-standard security measures to protect your information. All data transmitted between the Google Sheets Add-on, our servers, and third-party APIs is encrypted using HTTPS/TLS. We use secure services provided by Google Cloud to host our infrastructure and database.
6. Cookies
Our website (`http://sheetknow.com`) uses essential cookies to manage your login session and maintain the security of your account. These cookies are necessary for the website to function properly.
