Privacy Policy
Last updated: September 26, 2026
Summary
We do not sell your data. The militarycalc.com website does not use third-party advertising trackers. The free MilitaryCalc iOS app shows ads through Google AdMob; how that works and how to control it is explained under iOS app and advertising. We collect the minimum information needed to run the site and send you the email updates you opted in for.
Who we are (data controller)
The data controller for this site is MilitaryCalc, 10685-B Hazelhurst Dr #43316, Houston, TX 77043, USA. You can reach us about any privacy matter at [email protected].
What we collect
- Calculator inputs (ZIP, paygrade, etc.): Processed in your browser. Nothing is sent to our server unless you submit a form.
- Email subscriptions: If you subscribe to rate-change alerts, we store your email address and optional ZIP code in our own self-hosted email system.
- Analytics: We use privacy-respecting analytics (Google Analytics 4 with IP anonymization, and optionally Microsoft Clarity for usage understanding). These are analytics tools, not advertising trackers: we use them only to understand which calculators are used and where pages break, never to build advertising profiles or retarget you. Google Signals (cross-device advertising features in GA4) is turned off. No cross-site tracking.
- Server logs: Standard web server logs (IP, user agent, timestamps) retained 30 days for security and abuse prevention.
What we do not collect
- Social Security number, DOD ID, branch of service, deployment status, or any other personally-identifying military data.
- Bank, financial, or credit information.
- Location data beyond what you type into the calculator (and that stays in your browser).
How we use your information
- To send you the email updates you opted in for - a few times a year (typically 2-3 emails), only when rates or caps change or a new tool ships.
- To understand which calculators are most used so we can prioritize improvements.
- To prevent abuse (rate limiting, spam protection).
We store subscriber email on our own self-hosted email system. Messages are delivered through MailBaby (list and newsletter email) and Mailjet (sign-in links). Every email we send includes a one-click unsubscribe link. We honor unsubscribe requests immediately and never email an unsubscribed address again.
Data retention
- Email address: We keep your email until you unsubscribe. After you unsubscribe, we retain it only on a suppression list so we can comply with our legal obligation under CAN-SPAM never to email you again.
- Server logs: Retained 30 days, then deleted.
- Calculator inputs: Never leave your browser, so there is nothing for us to retain.
Cookies
On the website we use a minimal number of first-party cookies for analytics and remembering your last-used calculator inputs. The website does not use third-party advertising cookies.
iOS app and advertising
The MilitaryCalc iOS app is free and supported by ads served by Google AdMob (Google LLC). Calculator inputs in the app stay on your device, as on the website. We do not have accounts in the app and we do not receive your name, email or contact details from it.
- What the ad SDK processes: To show and measure ads, the Google Mobile Ads SDK processes device and usage data such as the advertising identifier (IDFA, only if you allow tracking), an app-specific identifier, IP address, device model and OS version, ad interactions, and crash and performance data. Google describes this in How Google uses information from sites or apps that use its services.
- Tracking permission (Apple ATT): The app asks for permission before any cross-app tracking. If you choose "Ask App Not to Track", the IDFA is not shared and you see less personalized ads. You can change this any time in iPhone Settings › Privacy & Security › Tracking.
- EEA, UK and Switzerland (GDPR): Before ads load, the app shows a consent message from Google's consent management platform. You can consent, refuse, or choose purposes and vendors individually. If you refuse, ads may still be shown on a limited, non-personalized basis where the law allows it. You can change your choice at any time with the Privacy choices button on the app's home screen.
- US state privacy laws: Residents of states with privacy laws (such as California, Colorado, Connecticut, Virginia and others) can opt out of the sale or sharing of personal information for targeted advertising through the same Privacy choices button. We honor these opt-outs by requesting restricted data processing from Google.
- Legal basis: For personalized ads in the EEA, UK and Switzerland we rely on your consent. Contextual, non-personalized ads rely on our legitimate interest in funding a free app.
- Removing ads: Where offered, an optional one-time in-app purchase removes ads. Purchases are handled by Apple; we never see your payment details.
Legal basis for processing (GDPR)
- Consent: We send marketing and rate-change email only because you opted in. You can withdraw consent at any time by unsubscribing, with no effect on email already sent.
- Legitimate interest: We keep short-lived server logs to secure the site and prevent abuse, which is in our legitimate interest in running a safe service.
Your rights
Depending on where you live, you may have the right to:
- Access the personal data we hold about you.
- Rectify inaccurate or incomplete data.
- Erase your data (the right to be forgotten).
- Restrict how we process your data.
- Object to processing based on legitimate interest.
- Port your data, receiving it in a portable format.
- Complain to a supervisory authority (for EU/UK residents, your local data protection authority).
You can unsubscribe from email at any time using the link in every email we send, or exercise any of the rights above by emailing [email protected]. We respond to all such requests within 7 business days.
International data transfers
MilitaryCalc is operated from, and its service providers are based in, the United States. If you contact us or subscribe from outside the US, your data is transferred to and processed in the US. Where required, such transfers rely on appropriate safeguards such as the EU Standard Contractual Clauses (SCCs) or the EU-US Data Privacy Framework (DPF) where applicable.
Third-party services
- Cloudflare for DNS and edge security.
- MailBaby and Mailjet for email delivery.
- Google Analytics 4 for usage statistics (IP anonymized).
- Microsoft Clarity (optional) for understanding calculator usage flows.
- Google AdMob for ads in the iOS app only (see iOS app and advertising).
Children
MilitaryCalc is intended for adults (service members, veterans, and their families). We do not knowingly collect information from anyone under 13.
Changes
If we update this policy, we will post the new version here with a fresh date. Material changes affecting how we handle email will be announced in our next subscriber email.
