FightNode Privacy Policy
Last updated: June 28, 2026
This Privacy Policy explains how FightNode handles data in the FightNode app, website, and BagNode training system. FightNode is the name used for the app and service. Privacy questions can be sent to fightnode1@gmail.com.
Data the app may access or collect
- Account data: email address, login identifier, and authentication data when you create or use a FightNode account.
- Training data: punch power, hit count, max hit, average power, total kilograms, quest/session type, timestamps, calories estimates, and session history.
- Ranking data: selected session results may be uploaded to FightNode online rankings when ranking features are used.
- Bluetooth data: Bluetooth is used to connect to BagNode sensors and supported heart-rate devices. The app does not need your physical location for training features.
- Heart-rate data: pulse/heart-rate readings may be shown live and saved in session history when a supported sensor is connected.
- Camera and microphone: camera and microphone permissions are used only when you choose camera/video training features. Videos are intended to be stored locally on your device unless you choose to share or upload them.
- Device and technical data: app version, device permissions, crash/debug information, and basic technical information may be processed by the app platform or service providers.
How data is used
FightNode uses data to provide live punch feedback, connect to BagNode hardware, show heart-rate data, save training history, record optional training videos, provide online rankings, authenticate users, prevent abuse, improve reliability, and provide support.
Sharing and service providers
FightNode does not sell personal or sensitive user data. Data may be processed by service providers needed to operate the app, such as Google Firebase Authentication, Firebase Realtime Database, Google Play services, and hosting providers. Data may also be disclosed if required by law or to protect the security of the app and users.
Local data on your device
Some training history, settings, and video files may be stored locally on your device. Local data can be deleted by using device/app storage controls, deleting videos from the device, or uninstalling the app.
Security
FightNode uses reasonable security measures and modern encrypted connections where data is transmitted to online services. No system can be guaranteed to be completely secure.
Retention and deletion
Online account and ranking data is kept while your account or ranking entry is active, or as needed to provide the service. You can request account deletion at fightnode.org/account-deletion.html. Some data may be retained longer where necessary for security, fraud prevention, legal, or compliance reasons.
Children
FightNode is intended for training use and is not directed to children. Young athletes should use FightNode only with appropriate adult, coach, or club supervision.
Changes to this policy
This policy may be updated when FightNode features, app store requirements, or legal requirements change. The updated date at the top of this page shows the latest version.
