Privacy Policy

Last updated: April 2026

Zloop is a local, on-device AI companion app. We do not collect, transmit, or sell any personal data. Everything Zloop does happens entirely on your device.

1. Who We Are

Zloop is developed and maintained by MammothDevs. Zloop is an animated AI eye overlay for Android that reacts to your phone activity, listens for its wake word, and interacts with you through sounds and speech — all locally on your device.

2. What Data We Collect

We collect no personal data. Zloop does not:

Create or require a user account
Store your name, email, phone number, or any identifiers
Send any data to MammothDevs servers or third-party servers
Use analytics, crash reporting SDKs, or advertising SDKs
Access your contacts, messages, photos, or files
Record or store audio recordings

3. Permissions We Request & Why

Zloop requires the following Android permissions to function. Each permission is used strictly for the stated purpose and nothing else.

Display Over Other Apps (SYSTEM_ALERT_WINDOW)

Required to draw Zloop's animated eye on top of your screen across all apps. Without this permission, Zloop cannot show its overlay. No content from other apps is read or recorded — Zloop only draws on top of them.

Accessibility Service (BIND_ACCESSIBILITY_SERVICE)

Used to detect which app is currently open so Zloop can react contextually — for example, making a sound when you open a food app, or looking toward the camera when you open it. Zloop reads only the active app package name and basic UI labels. It does not read your messages, passwords, personal content, or any sensitive data.

Microphone (RECORD_AUDIO)

Used exclusively to listen for Zloop's wake word ("Hey Zloop") and to process voice commands after the wake word is spoken. Audio is processed in real time using Android's built-in SpeechRecognizer API and is never stored or recorded by Zloop. Android's SpeechRecognizer may route audio through Google's speech services as part of the operating system — this is outside MammothDevs' control.

Phone State (READ_PHONE_STATE)

Used to detect when a phone call starts or ends so Zloop can pause its microphone listener during calls and react after calls end. No call details, phone numbers, or contact information are accessed or stored.

Foreground Service (FOREGROUND_SERVICE, FOREGROUND_SERVICE_MICROPHONE)

Required to keep Zloop running in the background as a persistent overlay service. Android requires apps that use the microphone in the background to declare this permission. Zloop displays a system notification while active so you always know it is running.

Vibrate (VIBRATE)

Used for light haptic feedback when you tap buttons inside the Zloop app. No data is involved.

4. On-Device Speech Recognition

Zloop uses Android's built-in SpeechRecognizer API to detect the wake word "Hey Zloop" and process voice commands. This API is part of the Android operating system and may use Google's cloud speech services depending on your device settings and configuration.

MammothDevs does not receive, store, or process any audio from your device. If you are concerned about Google's processing of speech data, you can review Google's privacy policy separately.

5. Data Storage

Zloop stores minimal preference data locally on your device only, including:

Your selected skin / eye style
Feature toggle preferences (voice on/off, app reactions on/off, etc.)
Calibration settings (eye size and position)

This data is stored using Android's local DataStore and never leaves your device.

6. Third-Party Services

Zloop does not integrate with any third-party analytics, advertising, or tracking SDKs. Zloop does not use Firebase, Mixpanel, Amplitude, Meta SDK, or any similar services.

The only external system involved is Android's SpeechRecognizer, which is an OS-level service managed by Google, not MammothDevs.

7. Children's Privacy

Zloop is not directed at children under the age of 13. We do not knowingly collect any information from children. Since we collect no personal data from any user, no special risk applies, but parents should supervise app usage as with any software.

8. Changes to This Policy

We may update this Privacy Policy from time to time. When we do, the "Last updated" date at the top of this page will be revised. We encourage you to review this page periodically. Continued use of Zloop after any changes constitutes your acceptance of the updated policy.
