Privacy Policy
Effective date: October 24, 2026
Barefoot Blender is a scuba gas blending and dive planning utility. It does not use ads, tracking pixels, or a Barefoot Blender account system. The installed mobile apps include no analytics SDKs. The website uses cookieless, aggregate page-view analytics, described below.
Data stored on your device
The app stores settings, last-used calculator inputs, custom gas definitions, and blend history locally on your device so the app can work offline. This local data is not sent to Barefoot Blender servers.
Website analytics
The website at trimix-blender.com uses Cloudflare Web Analytics to count page views and measure page load performance. Cloudflare, which already hosts the website, processes these measurements. Cloudflare Web Analytics does not set cookies, does not use local storage, and does not fingerprint or track individual visitors across sites. It reports aggregate metrics such as pages viewed, referring sites, country, browser and device type, and page load timings.
The analytics script runs only on the website. The installed mobile apps never load it. Calculator inputs, settings, custom gases, and blend history are not included in website analytics. Blocking the script with a content blocker does not affect how the website works.
Subscription data
Native app subscriptions are processed by the app store account used for purchase and managed through RevenueCat. These providers may process purchase receipts, subscription status, device store identifiers, app user identifiers, and diagnostic data needed to validate purchases and restore access.
Health and dive data
Barefoot Blender does not collect health data, location data, dive profiles, biometric data, or personally identifiable dive records.
Support
If you email support or submit an in-app bug report, your email address, optional contact address, and message content are used only to respond to your request. Contact: jkowall@gmail.com.
In-app bug reports may optionally include app version, platform, browser or native app context, browser user agent, URL path, active calculator tab, pressure and depth units, online status, viewport size, selected calculator inputs, and crash error message. Bug reports do not include full local storage dumps, subscription receipts, RevenueCat customer identifiers, environment variables, secrets, or stack traces by default.
