Overview
Runner's Tools is developed by Vermilion Apps. This policy explains what data the Android app accesses, how it is used, how long it is retained, and how you can delete it.
Data We Process
Runner's Tools does not require an account and does not collect personal data on our servers. The app works entirely on your device.
The app allows you to enter running and fitness-related information so its calculators can work. Depending on how you use the app, this may include pace, race time, race distance, elevation, elevation gain, elevation loss, temperature, humidity, age, sex, and unit preferences. Google Play may treat some of this information, such as age, sex, and fitness-related inputs, as Health Data.
How We Use Health-Related Data
Any health-related or fitness-related information you enter is used only to provide the app's features, including race prediction, age grading, training pace calculations, race splits, treadmill conversions, and environmental calculations.
We do not sell this data, share it with advertisers, or use it for profiling. We do not send it to Vermilion Apps servers or to third parties.
Permissions, Analytics, and Sharing
The Android app does not request health permissions, location permissions, contacts, camera, microphone, or account access. We do not use third-party analytics, advertising, or tracking SDKs in the app.
Storage, Retention, and Deletion
Your inputs and settings are stored locally on your device using Android app storage so your last-used values are available the next time you open the app. Vermilion Apps does not keep a server-side copy.
This locally stored data is retained until you delete it. You can delete it at any time by clearing the app's storage in Android system settings or by uninstalling the app. If you contact us for support, any information you include in your email is retained only as long as needed to respond to your request and handle follow-up support.
Children's Privacy
Runner's Tools does not knowingly collect personal information from children. Because app data stays on-device and no account is required, there is no server-side user profile for children or adults.
Changes to This Policy
We may update this privacy policy from time to time. If we do, we will post the revised version on this page and update the date below.
