Privacy Policy

Last Updated: May 2026

At RollerCoin Profit Calculator (rollercoincalculator.app), our priority is transparency and the protection of user privacy. We believe you should have full clarity about how your data is (or isn't) processed while using our tools.

1. Data Collection and Database Policy

Our platform does not possess any database. The data you input into the forms, such as hash power, target coin ratios, and calculation durations, are never saved, stored, or processed on any server. All calculations run strictly "Client-Side" on the memory (processor) of the internet browser you are using. In terms of player security, this is the highest standard possible.

2. Cookies and Local Storage

To prevent the system from resetting your data every time you enter, we utilize your browser's LocalStorage feature. Your previous inputs (which league you are in, the language you selected, etc.) are kept unencrypted strictly on your own device. This data is never sent to our servers.

3. Google Analytics and Statistical Data

For the purpose of improving our site, detecting which sections are read the most, and performance reporting, we use Google Analytics as a standard practice. These tools measure fully "anonymized" standard metrics such as time spent on the site, page visit rates, and rough geographical location information (country/city-based). No personal identification is ever made.

4. Advertising Networks (Google AdSense)

To cover our server expenses, third-party advertising and publisher networks such as Google AdSense have been integrated. Our advertising partners may use standard cookies and web beacons based on your browsing behavior in order to present personalized ads to you. This cookie management is handled entirely outside of our control and operates under the global privacy agreements of the respective organizations.

Third-party ad servers or ad networks use technologies like cookies, JavaScript, or Web Beacons that are sent directly to your browser when they serve advertisements. They automatically receive your IP address when this occurs. These technologies are used to measure the effectiveness of their advertising campaigns and/or to personalize the advertising content that you see.

To opt out of personalized advertising, you can visit the Google Ads Settings page. You may also manage cookies from other ad networks via the DAA opt-out page.

For more information on Google's privacy practices, please review the Google Privacy Policy.

5. Responsibility for External Links

Any risks arising from links directed to external sites found within our guides or advertising modules are entirely the user's own responsibility. We cannot be held liable for the privacy practices or contents of the aforementioned external sites.

6. Changes to This Policy

We reserve the right to update this Privacy Policy at any time. When significant changes are made, we will update the last modified date on this page. We encourage users to review our policy periodically.
