What this site collects

TankStockCalc does not require an account and does not store the tank or fish data you enter — all calculations run in your browser and are never sent to a server. Standard web server logs (IP address, browser type, pages visited) may be collected by our hosting provider for security and reliability purposes.

Cookies and advertising

This site may display advertisements served by Google AdSense. Google and its partners may use cookies or similar technologies to serve ads based on your prior visits to this or other websites. You can opt out of personalised advertising by visiting Google Ads Settings.

Analytics

We may use privacy-respecting analytics to understand aggregate traffic patterns (e.g., which pages are visited, general location by country). This data is not tied to your calculator inputs.
