Privacy Policy
RollerCoin Calculator ("we", "our website") respects your privacy and is committed to protecting your data. This policy explains what information is collected when you visit rollercoincalculator.app and how it is used.
1. Personal Data We Collect
We do not collect personal data.
There is no account creation, registration, or login on this site. We do not request or store your name, email address, phone number, or any similar personal identifier.
When using API mode, your username or hash power may be sent to the server for calculation purposes; however, this data is never stored in any database or persistent storage.
2. Automatically Collected Data
When you visit our site, some technical data may be collected automatically:
- IP Address (anonymized)
- Browser type and version
- Operating system
- Pages visited and visit time
- Referrer URL (where you came from)
This data is used solely for aggregate analytics and is never used to individually identify you.
3. Cookies
Our site uses cookies through the following third-party services:
Google Analytics
We use Google Analytics to analyze visitor traffic and usage patterns. Google Analytics collects anonymous visitor statistics via cookies. This data is stored on Google's servers. You can review Google's privacy policy here.
A-Ads (Anonymous Ads)
We use A-Ads, a privacy-first anonymous crypto advertising network, to serve ads on the site. A-Ads does not perform user profiling or personal data tracking. Learn more at the A-Ads privacy policy.
You can manage or disable cookies through your browser settings. However, this may affect certain site functionality.
4. Local Storage
We store your calculator preferences (language, block durations, etc.) in your browser's localStorage. This data remains only on your device and is never sent to any server.
5. Third-Party Links
Our site may contain links to third-party websites such as rollercoin.com and GitHub. When you click those links, their own privacy policies apply. We are not responsible for the content or privacy practices of those external sites.
6. Children's Privacy
Our site is not directed at children under the age of 13, and we do not knowingly collect personal data from this age group.
7. Data Security
Because we do not collect personal data, there is no sensitive user data stored on our end. Since calculator data is processed in-browser, the risk of a data breach is extremely low.
8. GDPR and CCPA Rights
If you are visiting from the European Union or California, you may have the following rights under applicable law:
- Right to access your data
- Right to request deletion of your data
- Right to object to data processing
The only data we collect is anonymous analytics. Since no personal data is held, deletion requests are largely inapplicable. For any questions, you can reach us via GitHub.
9. Policy Changes
We may update this privacy policy from time to time. For significant changes, the "Last updated" date at the top of this page will be revised. If you use this site regularly, we recommend checking this page periodically.
