1. Introduction

Mevo is an Android app developed within the Erasmus+ exchange programme to help users care for their mental and physical well-being.

The app offers meditation, workout planning, nutrition advice, and progress tracking, with content reviewed by:

Edyta Główka (psychologist, meditation, mood)
Marcin Krzysztoszek (certified trainer, workouts)
Ewa Mirowska (dietitian, nutrition)

2. Data We Collect

During the initial onboarding survey, we may ask for the following optional information:

Username
Date of birth
Weight (kg)
Height (cm)
Gender

App preferences stored locally:

Theme preference (light/dark/system)
Dynamic colors preference
Contrast settings (standard/medium/high)

These data help personalise the experience. No other personal data or unique identifiers are collected.

Note: Some new features allow direct input or use of device sensors. For privacy: weight provided at onboarding is used locally to choose a diet category; ephemeral text entered in 'Clear Worries' is processed in-memory and not persisted; the Stress & Fatigue Scanner uses the front camera for on-device analysis only.

2.1 Location Data

The app may request location permission to determine your country and provide local mental health support numbers.

Important: Location data processed locally, never transmitted.

Location used only to determine country
No precise coordinates stored
Location data not shared with third parties
You can deny location permission anytime

3. Purpose & Local Storage

All your answers are stored locally on your device using an encrypted Room database. We use them only to:

Personalise mood tracking
Suggest workout plans
Tailor nutrition tips
Show relevant progress dashboards
Customize app appearance and behavior
Provide country-specific mental health resources

Your data never leaves your device. We do not collect, transmit, share, or sell any personal data to servers or third parties.

Weight you optionally provide at onboarding is stored locally in encrypted form and used only to select an appropriate diet category. You can update or remove this data at any time in Settings.

The processing is based on your consent and our legitimate interest in providing personalised features without data transmission.

4. Permissions

Mevo may request following permissions:

Location access (coarse/fine)

Purpose: determine country for local support
Permission optional, can be denied
No precise location tracking
Location data never transmitted externally

All permissions can be managed in device settings.

Camera (front-facing):

Purpose: required for the Stress & Fatigue Scanner to capture frames for on-device analysis. Camera access is used only while the scanner is active. No images or video are saved or transmitted off-device; frames are processed in memory and discarded.

• Camera access is requested only when you start the scanner.
• No raw images or video are uploaded or retained by default.

Modify system settings / temporary brightness change:

Purpose: optionally adjust screen brightness during scanning to improve image quality. This permission is requested only if you enable the scanner and is optional — you may allow or deny it.

5. Third-Party Content & APIs

Mevo may offer links to external platforms (e.g., Spotify, YouTube, podcast apps). These open in your device's default apps. We do not exchange personal data with these platforms and we do not embed third-party SDKs.

6. Experimental AI Features

Some experimental features in Mevo make use of a locally running AI model:

The model file is downloaded once from Google Play Asset Delivery and stored locally on your device.
No personal data or conversation content is transmitted to Google Play or external servers.
All inputs are processed only on-device, in memory, and are not saved or shared.
Use of these features is entirely optional — the app functions without enabling them.
The AI model is provided in a beta version and may generate incorrect, biased, offensive, or harmful outputs.

Disclaimer: By using these features, you acknowledge these risks and agree to use them voluntarily and responsibly. We do not take responsibility for consequences of generated outputs. If you do not agree, please refrain from using these features.

7. Children's Privacy

Mevo is designed for general audiences. Children under the age of 13 should use the app only with parental supervision.

We do not knowingly collect any personal information from users under 13 and we do not serve ads.

If you are a parent or guardian and believe we have inadvertently stored information about your child, please contact us immediately.

8. Data Retention & Deletion

Your data is stored only on your device and remains there until you:

Reset data via the in-app settings menu
Uninstall the app, which deletes all associated records

There is no server-side copy or backup of your data.

Ephemeral inputs (e.g. text entered into 'Clear Worries') are processed in-memory and intentionally not saved to the local database. Camera frames used by the Stress & Fatigue Scanner are analysed in memory and discarded; the app does not store raw images. If you choose to save a scanner session summary, the summary may be stored locally but will not include raw image data.

9. Security

User data is stored in an encrypted Room database.

To further protect your privacy, please ensure your device is secured with a PIN code, password, or biometric lock.

The app requests minimal permissions, reducing risk of external access.

10. Policy Changes

Any updates to this policy will be shown both here and within the app.

In case of significant changes (e.g., involving cloud storage), we will notify you in-app and/or via available contact methods.
