Privacy Policy
Last Updated: February 9, 2026
Our Commitment to Privacy
At UngrindFi, we respect your privacy. We believe financial planning tools should be accessible without sacrificing your personal data. This privacy policy explains what minimal data we collect and how we use it.
Information We Collect
Calculator Data
All calculator inputs (age, savings, expenses, etc.) are processed entirely in your browser. We do not store, transmit, or save your financial information to any server. Your numbers stay on your device.
Email Addresses (Optional)
If you choose to email yourself your results, we collect your email address solely to send that one-time message. We do not add you to mailing lists, send marketing emails, or share your email with third parties.
Analytics (Anonymous)
We may use privacy-focused analytics to understand how visitors use our site (page views, general location, device type). This data is anonymous and aggregated - we cannot identify individual users.
How We Use Information
- To provide the Coast FIRE calculator functionality
- To send calculation results via email (only if requested)
- To improve the website based on anonymous usage patterns
- To maintain security and prevent abuse
What We Don't Do
- We don't sell your data to advertisers or third parties
- We don't require accounts or track individual users
- We don't send spam or marketing emails
- We don't share financial information (because we don't store it)
- We don't use invasive tracking or fingerprinting
Cookies
We may use essential cookies to remember your calculator preferences during your session. We do not use third-party advertising cookies or tracking pixels.
Third-Party Services
We use Resend for email delivery. When you request your results via email, your email address is transmitted to Resend solely to deliver that message. Resend's privacy policy applies to their handling of this data.
Our site is hosted on Vercel. Standard web server logs (IP addresses, browser types, etc.) may be collected by the hosting provider for infrastructure purposes.
Your Rights
Since we don't store personal data or maintain user accounts, there's no data to access, modify, or delete. You can clear your browser's local storage at any time to remove any calculator preferences.
Changes to This Policy
We may update this privacy policy from time to time. The "Last Updated" date at the top reflects the most recent changes. Continued use of the site constitutes acceptance of the current policy.
