This Privacy Policy explains how CalcWell (“we,” “us”) handles information from visitors to techtrader.shop.
Our calculators run entirely client-side in JavaScript. The numbers you enter are processed on your device to show a result and are not transmitted to us or stored on our servers.
Like most websites, we collect standard technical data — IP address, browser and device type, pages visited and referring page — to understand usage, improve content, and serve ads.
This site displays ads through Google, including Google AdSense and Google Ad Manager.
You may opt out of personalized advertising via Google Ads Settings, or interest-based ads from other vendors at optout.aboutads.info. See how Google uses data.
California residents may request access to or deletion of personal information, correct it, and opt out of its “sale” or “sharing.” We do not sell personal information for money, though advertising cookies may be considered “sharing” for targeted advertising. Use the opt-out links above or contact us; we will not discriminate against you for exercising your rights.
This site is not directed to children under 13, and we do not knowingly collect their information.
We may update this policy; the date above reflects the latest version. Questions: hello@techtrader.shop.
