Privacy Policy
Last Updated: October 2025
Our Commitment to Your Privacy
Prophecy is committed to protecting your privacy. This policy explains our approach to data collection and usage.
No User Data Collection
We do not collect, store, or process any personal information from users of this application.
Specifically, we do not collect:
- Names, email addresses, or contact information
- IP addresses or device identifiers
- Browsing history or usage patterns
- Cookies or tracking technologies
- Payment or financial information
- Location data
How the Application Works
Prophecy is a market analysis tool that processes publicly available historical market data to generate predictions using pattern-matching algorithms. All data processing occurs locally within the application, and no user-specific data is transmitted, stored, or shared.
The application uses:
- Public Market Data: Historical OHLC (Open, High, Low, Close) data from global stock indices
- Local Processing: All calculations and predictions are performed server-side without storing user preferences
- Session-Based Parameters: Configuration settings (e.g., similarity thresholds, day counts) are passed via URL query strings and are not stored
Third-Party Services
The application may fetch market data from third-party sources such as Yahoo Finance or Google Sheets. These requests are made server-side, and your usage of this application does not directly expose your information to these services. Please refer to these services' privacy policies for information on how they handle data:
No Authentication or Accounts
This application does not require user accounts, registration, or authentication. You can use all features without providing any personal information.
Server Logs
Like most web applications, our server may generate standard technical logs for debugging and operational purposes. These logs may include:
- HTTP request methods and response codes
- Timestamps of requests
- Error messages and stack traces
These logs are used solely for troubleshooting and are not used to identify or track individual users. They are not shared with third parties.
Data Security
Since we do not collect user data, there is no personal information at risk. The market data used by this application is publicly available and does not contain any user-specific information.
Children's Privacy
This application does not collect any information from anyone, including children under the age of 13. No special permissions or parental consent are required.
Changes to This Policy
If our data collection practices change in the future, we will update this privacy policy and note the revision date at the top of this page. However, our commitment to privacy remains: we will never collect personal data without clearly informing users and obtaining necessary consent.

If you have any questions about this privacy policy or the application's practices, please contact the application administrator.
