Privacy Policy

Last updated: April 16, 2026

1. Who We Are

ErgoVision AI ("we", "us", "our") is an Android application that analyzes desk posture using on-device computer vision and ergonomic scoring. This policy explains what data the app handles, how we protect your privacy, and the choices you have.

Contact: admin@ergovision.app

2. Data We Handle

Camera and Photos

When you run a posture scan, the app uses your device camera to capture photos. These photos are analyzed on your device using Google MediaPipe (on-device machine learning) and never leave your phone unless you explicitly enable an optional feature (see below).

• Photos are stored in the app's private storage (not the public gallery).
• Photos can only be accessed by this app — other apps cannot read them.
• You can delete any scan result at any time, which also deletes the associated photo.

Pose Landmark Data

The app computes 33 body landmark points (shoulders, elbows, knees, etc.) from each photo using on-device machine learning. This data is used to calculate ergonomic scores (RULA methodology) and posture fix suggestions. It is stored locally alongside the scan result.

3. Optional Features

AI Enhancement (Google Gemini)

If you enable AI Enhancement in settings, your posture photo is sent to Google's Gemini API for additional contextual analysis (e.g., checking if your monitor is too low). This is an optional enhancement — the app produces complete posture analysis without it.

When AI Enhancement is enabled:

• The photo is sent to Google's servers via HTTPS.
• Google processes the photo according to their Generative AI Terms.
• The response (body part ratings, equipment observations) is returned to your device and merged with on-device results.
• Google's data handling for this API is described in their privacy policy.

You can turn AI Enhancement off at any time. When off, zero data is sent to Google — the app runs fully offline.

Help Improve ErgoVision (Training Data Collection)

If you enable Help Improve ErgoVision, the app saves anonymized workspace photos on your device. You choose when (and whether) to upload them to our training dataset, hosted on Google Firebase Storage.

Before any photo leaves your device:

• Your face is cropped out entirely — the photo is cut at shoulder level and above. Hair, face, and any identifying features are never included.
• Only pose landmark data (body joint positions) is saved alongside — no image pixel coordinates that could locate a face.
• No device model, hardware fingerprint, phone number, email, account name, or advertising ID is stored.
• An anonymous random identifier groups your uploads for quality review — this ID is not tied to any personal identifier.

Uploaded data is used to train a future on-device ergonomic analysis model. We do not sell, share, or publish this data. It is accessible only to the ErgoVision AI development team for model training purposes.

This feature is off by default. You must explicitly enable it and explicitly tap the Upload button — nothing uploads automatically.

4. What We Don't Do

• We do not use any advertising SDKs or trackers.
• We do not collect your contacts, location, browsing history, or any other app's data.
• We do not use Google Analytics, Facebook SDK, or any similar tracking service.
• We do not sell your data to anyone, ever.
• We do not require an account or sign-in. The app works without any login.

5. Data Storage Locations

• On your device: All scan results, photos, and landmark data — always.
• Google Gemini servers: Only the current photo being analyzed, and only if you enable AI Enhancement. Not stored by us.
• Google Firebase Storage: Only anonymized (face-cropped) workspace photos and landmark data, and only if you enable Help Improve ErgoVision and manually tap Upload.

6. Your Rights and Choices

• Delete your data: Clearing app data (Android Settings > Apps > ErgoVision AI > Storage > Clear data) removes all local scan results, photos, and preferences.
• Request deletion of uploaded training data: Email admin@ergovision.app — we will delete data associated with your anonymous device ID (visible in the app's settings if needed).
• Disable optional features at any time: Toggle AI Enhancement or Help Improve ErgoVision off in the home screen. Previous uploads are not automatically deleted but can be deleted on request.
• Access or export your data: On-device scan results are stored as JSON files in the app's private storage. Email us if you need help accessing them.

7. Children's Privacy

ErgoVision AI is not directed at children under 13. We do not knowingly collect data from children. If you believe a child has used the app, contact us and we will delete any associated data.

8. Medical Disclaimer

ErgoVision AI provides wellness guidance based on established ergonomic standards (RULA methodology). It is not a medical device and does not provide medical advice, diagnosis, or treatment. Consult a qualified healthcare provider for any medical concerns related to posture, pain, or ergonomic injury.

9. Permissions We Request

• Camera: To capture posture photos for analysis.
• Read media (photos): To let you analyze existing photos from your gallery.
• Microphone: Required by Android CameraX for video recording mode (audio is not saved or analyzed).
• Internet: Only used when AI Enhancement or the Upload feature is actively invoked by you.

We do not request location, contacts, SMS, call logs, or any other permission.

10. Security

All network traffic uses HTTPS with TLS 1.2 or higher. Firebase Storage uploads are restricted to authenticated write operations only — uploaded data is not publicly readable. API keys embedded in the app are restricted to this app's package name and signing certificate.

11. Changes to This Policy

We may update this policy to reflect new features or legal requirements. Material changes will be announced in the app. The "Last updated" date at the top of this page reflects the most recent revision.
