Qanvion is a free Chrome extension that provides offline position sizing and risk/reward calculations for educational and informational purposes.
We respect user privacy and are committed to transparency about how the extension handles data.
Users may manually enter account balances, risk percentages, entry prices, stop-loss prices, and take-profit prices.
These values are processed locally within the browser to generate calculations.
Qanvion does not collect or transmit these inputs to our servers.
The current version of the Qanvion Chrome extension:
Does not require user registration or login.
Does not collect personal or financial information on our servers.
Does not connect to brokerage or cryptocurrency exchange accounts.
Does not track browsing activity.
Does not use advertising trackers or analytics.
Does not sell, share, or transfer user-entered calculation data to third parties.
All position sizing and risk/reward calculations are performed locally in the user's browser.
No internet connection or external API is required for the calculation functions.
The extension does not request special browser permissions or access to users' browsing history.
Because calculation inputs are not transmitted to Qanvion servers, they are not stored in our remote systems.
We may update this Privacy Policy when the extension's features or data practices change.
Any material changes to data processing practices will be reflected in an updated policy.
For privacy-related questions, users may contact the developer through the verified publisher contact email displayed on the Qanvion Chrome Web Store listing.
Qanvion is an informational calculation tool. It does not execute trades, manage investment accounts, or provide personalized financial advice.
