Our commitment: We collect only what we need to provide our service. Your portfolio data stays in your Google Sheets™. We never sell your data to anyone.
In this policy, we explain what data we collect and why, how your data is handled, and your rights regarding your information. This policy applies to DeFiSheets, a Google Sheets™ add-on for cryptocurrency portfolio tracking.
For your convenience, here are quick links to each section:
Our guiding principle is to collect only what we need to provide DeFiSheets functionality. Here's what that means:
When you install DeFiSheets, we access your Google account information including your email address and basic profile information. This allows us to authenticate you and provide the add-on functionality within Google Sheets™.
DeFiSheets requires permission to read and write data in your Google Sheets™. This is essential for our core functionality - fetching crypto prices and updating your portfolio calculations. Your spreadsheet data remains in your Google account and is not stored on our servers.
When you use DeFiSheets functions, we make requests to cryptocurrency price APIs on your behalf. We temporarily process this data to return current prices and market information to your spreadsheet, but we don't store your specific cryptocurrency holdings or portfolio details.
We collect basic usage analytics such as which functions are used most frequently and general error logs. This helps us improve the add-on and fix bugs. This data is aggregated and doesn't include your specific portfolio information.
We use your Google account access to authenticate you and provide DeFiSheets functionality within Google Sheets™. We use third-party cryptocurrency APIs to fetch real-time price data when you request it.
We analyze usage patterns and error logs to identify areas for improvement, fix bugs, and develop new features. This analysis uses aggregated, anonymized data.
We may use your email address to send important service updates, security notices, or information about new features. We won't send marketing emails without your explicit consent.
Important: We never access, store, or analyze your specific cryptocurrency holdings, portfolio values, or trading strategies. Your financial data stays private in your Google Sheets™.
Security is paramount when dealing with financial information, even indirectly:
You have several rights regarding your personal information:
To exercise these rights, you can contact us or simply remove the DeFiSheets add-on from your Google account, which will immediately revoke our access.
We retain different types of data for different periods:
DeFiSheets integrates with several third-party services:
These services have their own privacy policies, and we encourage you to review them.
We may disclose your information in limited circumstances:
We will never sell your personal information to advertisers or data brokers.
DeFiSheets is operated from the United States. If you're using our service from outside the US, your information may be transferred to and processed in the United States. We take appropriate measures to ensure your data is protected according to applicable privacy laws.
We may update this privacy policy from time to time to reflect changes in our practices or for legal compliance. We'll notify users of significant changes by updating the date at the top of this policy and, for material changes, by sending a notification through the add-on or via email.
If you have questions about this privacy policy or how we handle your data, please contact us through our support channels or by creating an issue in our documentation.
Remember: You can always remove DeFiSheets from your Google account at any time through your Google Workspace add-ons settings, which will immediately revoke our access to your account.
