Privacy Policy
At Doom Calculator, we take your privacy seriously. This Privacy Policy explains how we handle information when you use our website and services. Our commitment to privacy is absolute: we designed this platform from the ground up to ensure that your sensitive financial, personal, health, etc data never leaves your device. This document details our practices regarding data collection, storage, and usage.
Information We Do Not Collect
Unlike most online services, we do not collect, store, or transmit any of your personal or financial information to our servers. When you enter spending amounts, select categories, or adjust reduction sliders, all processing occurs locally within your web browser. Your financial data is yours alone, and we believe it should stay that way.
Local Storage and Session Data
To enhance your experience, we use your browser's session storage to temporarily save audit data while you navigate the site. This allows you to view your spending calculations on the audits page without requiring you to re-enter information. This data exists only in your browser's memory and is automatically cleared when you close the browser tab or window. We do not use localStorage or any persistent storage mechanisms that would retain your data between sessions. If you refresh the page, your saved audits will reset, ensuring that no financial information remains on your device longer than necessary.
Technical Information
Like all websites, our server automatically receives certain technical information when you visit our site, including your IP address, browser type, operating system, and the pages you request. This information is used solely for server maintenance, security monitoring, and improving site performance. We do not correlate this technical data with any financial calculations you perform. Logs containing IP addresses are automatically deleted after 30 days.
Third-Party Services
Our website uses Tailwind CSS via CDN (Content Delivery Network) for styling and Chart.js for data visualization. These resources are loaded from external servers, which may log basic request information such as your IP address. However, these services do not have access to any data you enter into our calculator forms. We have selected these providers based on their own privacy commitments and industry reputation.
Cookies and Third Party Advertising
We allow third-party advertising on our site to support our free services. These advertisers may use cookies and other tracking technologies to collect information about your browsing behavior across different websites. This data is used to deliver personalized ads based on your interests. We do not have access to the data collected by these third-party advertisers, and we encourage you to review their privacy policies for more information on how they handle your data. If you prefer not to have this information collected, you can opt out of personalized advertising through your browser settings or by visiting the Digital Advertising Alliance's opt-out page. So that's why our website may use the cookies and some ads to get you more and more accurate and personalized ads. We do not use cookies for any other purpose, and we do not share any of your personal information with advertisers. We are just collecting some fund to improve the site more and more powerful and help the advertisers too to reach the right audience. We are committed to transparency about our advertising practices and will continue to prioritize your privacy while providing valuable tools and resources for financial management.
Data Security
Since all financial calculations occur client-side, the risk of data breach is minimized. We employ HTTPS encryption for all data transmitted between your browser and our servers, ensuring that your connection to our site is secure. We regularly update our security practices to address emerging threats and vulnerabilities. However, users should be aware that the security of data stored in browser memory depends on their own device security—if you share a computer or use public terminals, be sure to close the browser after use.
Children's Privacy
Our services are not directed to individuals under the age of 13. We do not knowingly collect personal information from children. If you are a parent or guardian and believe your child has provided us with personal information, please contact us immediately so we can remove such information from our records.
Changes to This Policy
We may update this Privacy Policy from time to time to reflect changes in our practices or for other operational, legal, or regulatory reasons. We will notify users of any material changes by posting the new policy on this page with an updated "Last Updated" date. We encourage you to review this policy periodically to stay informed about how we protect your information.
Contact Us
If you have any questions about this Privacy Policy or our privacy practices, please contact us through our website. We are committed to transparency and will respond to your inquiries promptly. Your trust is our most valuable asset, and we work continuously to maintain it through responsible data stewardship.
