Overview
Codemicros ("we", "us") operates the Calqen website. This policy explains what information the website collects, how it is used, and the choices you have. By using this website, you agree to the collection and use of information as described here.
Information we collect
The scientific calculator, graphing tool, equation solver, statistics tool and unit converter run entirely as JavaScript in your browser. Inputs, results and calculation history are stored only in your browser's local storage on your own device and are never transmitted to or stored on our servers. We do not require an account, and we do not knowingly collect names, email addresses or other personal information through the calculator tools.
If you email us for support, we receive whatever information you choose to include in that message (such as your email address and message content), which we use only to respond to you.
Cookies and advertising
This website displays ads served by Google AdSense. Google and its advertising partners may use cookies, device identifiers or similar technologies to serve ads based on your prior visits to this or other websites. You can learn more about how Google uses this data and manage your ad personalization settings at policies.google.com/technologies/ads and adssettings.google.com.
Analytics
We do not run separate analytics software on this website beyond the aggregated, non-identifying measurement data that Google AdSense may collect as part of ad delivery.
Data security
Because calculations are performed locally in your browser, there is no calculation data in transit or stored on our servers to secure. Any support emails you send us are handled through standard email infrastructure.
Your choices
You can clear your browser's local storage at any time to remove saved calculator history. You can also adjust your browser's cookie settings or use Google's ad personalization controls to limit how ads are tailored to you.
Children's privacy
This website is not directed at children under 13, and we do not knowingly collect personal information from children.
Third-party links
The website links to third-party destinations such as Google Play and codemicros.com. We are not responsible for the privacy practices of those third-party sites.
Changes to this policy
We may update this policy from time to time. Changes will be posted on this page with a revised effective date.
