Privacy Policy
Last updated: 15 June 2026
This Privacy Policy explains how BestProfitCalculator.com (“we”, “us”, or “our”) collects, uses, and protects information when you use our website and tools (the “Service”). By using the Service, you agree to the practices described here.
Information We Collect
- Account information. If you create an account, we store your email address, an optional display name, and a securely hashed version of your password (we never store your password in plain text).
- Saved calculations. If you choose to save a calculation to your account, we store the values you entered (such as prices, costs, and fees) so you can access them later.
- Calculator inputs. Numbers you type into the calculators are processed in your browser to show results. We do not store these unless you explicitly save them to your account.
- Log and technical data. Like most websites, our servers may automatically record information such as your IP address, browser type, pages visited, and timestamps, for security, abuse prevention, and diagnostics.
- Cookies. We use cookies and similar technologies as described below.
How We Use Information
- To provide and operate the calculators and account features.
- To authenticate you, keep you signed in (if you choose), and let you save and retrieve calculations.
- To send transactional emails you request, such as password-reset links.
- To protect the Service against spam, fraud, and abuse (including rate limiting and bot protection).
- To maintain, analyze, and improve the Service.
Cookies
We use the following types of cookies:
- Essential cookies. A session cookie keeps you signed in during your visit, and an optional “remember me” cookie keeps you signed in across visits if you select that option. These are required for the account features to work.
- Security cookies. We use Cloudflare Turnstile to tell humans and bots apart on sign-up and sign-in. This may set cookies and process limited technical data to perform the verification.
- Advertising cookies. In the future we may display ads served by third parties (see “Advertising” below), which may use cookies.
You can control or delete cookies through your browser settings. Disabling essential cookies may prevent the account features from working.
Advertising
We may use third-party advertising companies, including Google AdSense, to serve ads when you visit the Service.
- Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this and other websites.
- Google’s use of advertising cookies enables it and its partners to serve ads to you based on your visit to this site and/or other sites on the Internet.
- You may opt out of personalized advertising by visiting Google Ads Settings. You can also opt out of some third-party vendors’ use of cookies for personalized advertising at www.aboutads.info.
- For more information about how Google uses data, see How Google uses information from sites or apps that use our services.
Third-Party Services
We rely on a few trusted third parties to operate the Service, which may process limited data on our behalf:
- Cloudflare — content delivery, security, and bot protection (Turnstile).
- Google AdSense — advertising (when enabled).
- Our hosting provider — website and email delivery for transactional messages.
How We Share Information
We do not sell your personal information. We share information only with the service providers above to operate the Service, or when required by law, or to protect our rights and the safety of our users.
Data Retention & Deletion
We retain account information and saved calculations for as long as your account is active. You can delete your account at any time from your account page, which permanently removes your profile, email, and saved calculations from our active systems.
Security
We take reasonable measures to protect your information, including password hashing, encrypted connections (HTTPS), CSRF protection, and rate limiting. However, no method of transmission or storage is completely secure, and we cannot guarantee absolute security.
Children’s Privacy
The Service is not directed to children under 13 (or the minimum age required in your jurisdiction), and we do not knowingly collect personal information from them. If you believe a child has provided us information, please contact us so we can remove it.
Your Rights
Depending on your location, you may have rights to access, correct, or delete your personal information, or to object to or restrict certain processing. You can exercise many of these rights directly from your account page, or by contacting us.
International Visitors
Our servers may be located in a different country than you. By using the Service, you understand your information may be processed in those locations.
Changes to This Policy
We may update this Privacy Policy from time to time. When we do, we will revise the “Last updated” date above. Continued use of the Service after changes means you accept the updated policy.
