Privacy Policy & Cookie Disclosure
Last updated: October 25, 2026
Portfolio data: Orders, holdings and CSV/JSON imports are stored and processed in this browser. They are not included in analytics. Export a backup before clearing browser storage. Your browser preferences and privacy choice are also saved locally.
Requests and service logs: Looking up a ticker sends the symbol and requested market date to our calculation service. Hosting and market-data providers process requests and technical information such as IP addresses to deliver the service. Local portfolio storage does not mean that browsing generates no network requests.
Optional analytics: Google Analytics measures page visits and ticker lookups only after you choose to allow it. It may use analytics cookies and pseudonymous browser/session identifiers. When the Google tag is unavailable, our first-party analytics relay is subject to the same choice. Refusing optional analytics does not affect the calculator or your portfolio.
Your choices: Use Privacy choices in the footer to allow or withdraw optional analytics. Withdrawing stops future analytics sent by this app and removes its analytics identifiers where accessible. It does not delete data already received by Google. See Google's privacy policy for its data practices.
Advertising: Ads are currently disabled. We do not load advertising tags or enable personalized advertising. Any future advertising release requires updated disclosures and the applicable consent setup before activation.
Contact: For privacy questions or data-rights requests, use Contact . Clear locally saved portfolio data using the app's reset control or your browser settings; keep a backup if you need the records.
