Privacy Terms of Use Support

Privacy Policy

RunCalc runs entirely on your device. We do not collect, transmit, or store personal data on external servers.

• Conversion history & favorites: stored only on your device.
• Location: used only to detect a nearby track when you allow it. Coordinates never leave the device.
• Altitude: read from the device barometer/GPS when permitted. Never transmitted.

Purchases

We do not collect, sell, or share your personal data. There is no advertising and no third-party analytics or tracking SDKs. Purchases are processed by Apple; subscription status is managed via RevenueCat, which receives an anonymous app user ID and the App Store transaction — never your name, contacts, or content.

Children

This app is not directed at children under 13 and does not knowingly collect data from them.

Terms of Use

By downloading or using RunCalc, you agree to Apple's Standard End User License Agreement (EULA), available at apple.com/legal/internet-services/itunes/dev/stdeula, together with the terms below.

Subscriptions & purchases

RunCalc offers auto-renewing monthly and annual subscriptions. Payment is charged to your Apple ID at confirmation of purchase. Your subscription renews automatically unless auto-renew is turned off at least 24 hours before the end of the current period, and your account is charged for renewal within 24 hours prior to the end of the current period. You can manage or cancel your subscription at any time in your App Store account settings; cancellation takes effect at the end of the current billing period. A one-time lifetime purchase is also available — it is a non-consumable, one-time payment and does not auto-renew. Prices are shown in the app and may vary by region.

Disclaimer

RunCalc is NOT affiliated with the NCAA. Conversions are high-quality estimates calibrated against published championship-meet conversions, not official marks. The NCAA historically does not convert altitudes below 3000 ft, and RunCalc matches that rule. The app is provided "as is," without warranties of any kind; to the extent permitted by law, we are not liable for any damages arising from your use of it.
