Privacy Policy

Effective date: 2026-04-28 Last updated: 2026-04-28

This privacy policy applies to Sentry Cam (the “Application”), a mobile app for Android and iOS that lets you control EZVIZ security cameras. The Application is created and operated by Kanishka Gunawardana (the “Service Provider”). The Application is offered as a free, ad-supported service and is provided “as is”.

What information the Service Provider collects

The Service Provider does not operate any backend server, run analytics on user behaviour, or collect any data on the developer’s own infrastructure. All of the data the Application uses lives in one of three places:

1. On your device only

The following data is stored only on your device, in operating-system-protected storage (iOS Keychain / Android Keystore for credentials; AsyncStorage for non-secret preferences) and is never sent to any server controlled by the Service Provider:

• Your EZVIZ account email and password (used to log in to your EZVIZ account).
• Your EZVIZ session token.
• The list of cameras associated with your EZVIZ account, including their names and serial numbers.
• Your per-camera preferences (siren and notification settings, last-used mode).
• If you opt in to the “auto-return” geofence feature: a “home” latitude / longitude that you choose, plus the geofence radius.

2. Sent to EZVIZ cloud (Hangzhou Ezviz Network Co., Ltd)

The Application is a third-party client to the EZVIZ cloud — the same cloud the official EZVIZ app uses. To control your cameras, the Application sends:

• Your EZVIZ login credentials (transmitted over HTTPS) when you sign in.
• Camera control commands (e.g. arming, schedule changes) when you press AWAY or HOME.
• Standard request metadata (IP address, app identifier, region) that EZVIZ requires to route requests.

EZVIZ’s privacy policy applies to anything sent to or stored by EZVIZ: https://www.ezviz.com/privacy.

3. Sent to Google AdMob

The Application displays banner and interstitial advertisements via Google AdMob. AdMob may collect the standard data it collects across all apps that use it, including your device’s advertising ID, IP address, device information, and ad-interaction events. Where supported, the Application requests non-personalised ads. Google’s privacy policy applies: https://policies.google.com/privacy.

Background location

If you opt in to the “auto-return” geofence feature, the Application requests background location permission so the operating system can wake the Application when your device crosses a self-defined boundary. The location coordinates are used only by the OS-level geofencing service for that purpose; they are not stored beyond what is needed for the geofence to function and are not sent to any server operated by the Service Provider.

You can revoke background location at any time through your device’s system settings. Doing so disables auto-return; manual AWAY / HOME still works.

What the Service Provider does NOT collect

To be explicit, the Service Provider does not:

• Operate any backend server, analytics endpoint, or telemetry endpoint.
• Collect, store, or process video, audio, or thumbnails from your cameras.
• Track which screens you visit, how long you spend in the app, or which buttons you press.
• Have any way to read your EZVIZ password — it lives in your device’s secure storage.

Children

The Application is not directed to children under 13 and does not knowingly collect personal information from children. If you believe a child under 13 has provided personal data through the Application, please contact the Service Provider and the relevant data will be removed where the Service Provider has any access to it.

Your rights

• Sign out in the Application clears your stored EZVIZ credentials and session token from the device.
• Uninstall the Application to remove all locally stored data.
• Reset your advertising ID or opt out of ad personalisation through your device’s privacy settings.
• For data held by EZVIZ or Google, refer to their respective privacy policies linked above.

Data retention

The Service Provider does not retain any user data on its own infrastructure (because it has no infrastructure). Data held on your device persists only until you sign out or uninstall.

Security

The Application uses HTTPS for all network requests and stores credentials in operating-system-protected secure storage (iOS Keychain / Android Keystore). However, no method of transmission or storage is 100% secure; you should also use a strong, unique password on your EZVIZ account.

Changes to this policy

This policy may be updated from time to time. Updates will be posted at the same URL where you read this. Continued use of the Application after a change constitutes acceptance of the updated policy.
