Privacy Policy
Effective May 18, 2026 — How Ballistic Science Lab collects, uses, and protects your information.
This Privacy Policy describes how Ballistic Science Lab ("we," "us," or "our"), operated at BallisticScienceLab.com, collects, uses, and shares information about you when you use our website and services (collectively, the "Service"). By using the Service, you agree to the collection and use of information as described in this policy.
1. Information We Collect
We collect the following categories of information:
Account Information
When you create an account, we collect your email address and a password (stored as a secure hash — we never store your plain-text password). Your name or username is optional and used only for display purposes.
Usage Data
When you use the ballistic calculator or other tools, we may log general usage information such as pages visited, features used, and session duration. This data is used in aggregate to improve the Service and is not linked to your identity unless you are logged in.
Saved Data
If you create an account and save calculations or custom cartridge loads, that data is stored in association with your account so you can retrieve it later.
Automatically Collected Information
Like most websites, we automatically receive standard server log information when you visit, including your IP address, browser type, referring/exit pages, and date/time stamps. This information is used for security, diagnostics, and general analytics.
2. How We Use Your Information
We use the information we collect to:
- Provide, operate, and maintain the Service
- Allow you to create and manage a user account
- Save and retrieve your calculations and custom cartridge loads
- Improve and develop the Service based on aggregate usage patterns
- Respond to support requests or inquiries
- Display relevant advertising through third-party ad networks (see Section 4)
- Detect and prevent fraud or abuse
3. Cookies and Tracking Technologies
Ballistic Science Lab uses cookies and similar technologies to operate the Service. Cookies are small text files stored on your device. We use them for:
- Keeping you logged in to your account (session cookies)
- Remembering your preferences
- Analytics to understand how users interact with the site
Third-party advertising partners (including Google AdSense) may also place cookies on your device to serve personalized ads based on your browsing history. You can opt out of personalized advertising through the NAI opt-out tool at optout.networkadvertising.org or through your browser settings.
4. Third-Party Advertising
We use Google AdSense and may use other third-party advertising networks to display ads on the Service. These networks may use cookies and other tracking technologies to serve ads based on your prior visits to this website and other sites on the internet.
Google's use of advertising cookies enables it and its partners to serve ads based on your visit to our site and/or other sites on the Internet. You may opt out of personalized advertising by visiting Google's Ads Settings at adssettings.google.com.
We may also participate in affiliate marketing programs (such as MidwayUSA, Brownells, or OpticsPlanet). When you click an affiliate link, those services may collect information per their own privacy policies.
5. Data Sharing and Disclosure
We do not sell your personal information. We may share information in the following limited circumstances:
- Service Providers: We may share data with trusted vendors who assist in operating the Service (e.g., hosting provider), under confidentiality obligations.
- Legal Compliance: We may disclose information if required by law, court order, or government request, or to protect the rights and safety of our users or the public.
- Business Transfer: If the Service is acquired or merged, your data may transfer as part of that transaction. We will notify you of any material change.
6. Data Retention
We retain your account information and saved data for as long as your account is active. If you delete your account, your personal data and saved calculations will be permanently deleted within 30 days. Anonymized aggregate usage data may be retained indefinitely for analytical purposes.
7. Your Rights and Choices
Depending on your location, you may have the right to:
- Access the personal information we hold about you

- Opt out of marketing communications
To exercise any of these rights, contact us via our contact form. We will respond within 30 days.
8. Security
We use industry-standard security measures including HTTPS/TLS encryption in transit and hashed password storage. No method of transmission or storage is 100% secure; we cannot guarantee absolute security but take reasonable precautions to protect your data.
9. Children's Privacy
The Service is not directed to children under the age of 13. We do not knowingly collect personal information from children under 13. If you believe we have inadvertently collected such information, please contact us and we will delete it promptly.
10. Changes to This Policy
We may update this Privacy Policy from time to time. When we do, we will revise the Effective Date at the top of this page. Continued use of the Service after changes are posted constitutes acceptance of the updated policy. For material changes, we may provide additional notice (such as an in-app notification).
