EG4 Live — Privacy Policy
Last updated: July 20, 2026
EG4 Live is a personal monitoring app for EG4 solar inverter systems. It is read-only: it
displays data from your inverter and never changes any inverter settings.
What the app collects and stores
- EG4 account credentials. When you sign in, your username and password are sent directly
to EG4's own servers to authenticate you — the app does not store your password. After a
successful sign-in, EG4 issues a session token, which the app stores securely on your device
(using Android's encrypted secure storage) so you don't have to sign in every time. This token
never leaves your device except when the app uses it to talk to EG4's own API.
- Biometric unlock (optional). If you enable fingerprint/face unlock for faster sign-in, that
authentication happens entirely on your device through Android's own biometric system. The app
never receives or stores your biometric data — it only receives a yes/no confirmation from the
operating system.
- Local notifications (optional). If you turn on alerts, the app schedules notifications on
your device for conditions it detects (e.g. a low-battery warning). These are on-device
notifications, not push notifications sent through a remote server the developer operates.
What the app does NOT do
- No analytics, advertising, or tracking SDKs of any kind.
- No crash reporting or usage-analytics service.
- No data is sold or shared with any third party other than EG4 itself (the inverter-monitoring
service you already have an account with, to display your own system's data back to you).
- No account or data is created or stored on any server operated by this app's developer — all
data lives on EG4's own servers (your inverter data) or on your device (your session and any
alert preferences).
Data deletion
Signing out of the app clears the locally stored session token. Because the app stores nothing
on a developer-operated server, there is no separate "delete my account" step — signing out and
uninstalling the app removes everything the app itself stored.
