Privacy Policy

Last updated: August 31, 2026

This Privacy Policy explains how we process your personal data when you use the ebuds mobile application and the ebuds.tr website (the "Service"). The Service is provided by Ebuds Teknoloji Anonim Şirketi ("ebuds", "we").

ebuds enables two people who speak different languages to talk with real-time voice translation. Call audio is processed instantly and relayed to the other party; it is not permanently stored on ebuds servers. The app also offers video calling and an augmented reality (AR) feature that lets you virtually try products on your face. The app also includes Eva, a voice assistant designed for use with Bluetooth glasses and headsets.

1. Data we process

a) Account information

• Your name, e-mail address, and password (the password is stored only in encrypted/hashed form).
• Your membership/subscription status (plan, start/end dates).

b) Call and voice assistant (Eva) audio

• Audio captured from your microphone during a call is processed for real-time translation.
• This audio is transmitted to our AI provider (Google — Gemini) to generate the translation.
• The ebuds relay server only passes the audio between the two parties in real time; it does not keep recordings.
• If you use the Eva voice assistant: while Eva mode is on, wake-word ("Hey Eva") detection runs entirely on your device; no audio leaves your device until the wake word is detected.
• After the wake word is detected (or when you start a conversation manually), your speech is transmitted to Google (Gemini) to generate the answer. Conversation audio is not stored on ebuds servers; ebuds only records your usage time (minutes).
• You can turn Eva mode off at any time; while it is off, the microphone is not used for this purpose.

c) Video calls (camera)

• When you use the video call feature, the image captured by your camera is transmitted in real time only to the other party in the call.
• The video stream is established directly between the devices (peer-to-peer); ebuds does not record the video or store it on its servers.

d) Face Data (TrueDepth / ARKit)

• The "Try On" feature in the app uses Apple's ARKit face tracking technology (including TrueDepth APIs) to let you virtually try products on your own face. When you use this feature, your device's front camera captures the position, orientation, and facial geometry (face mesh) of your face.
• This data is used solely to render the 3D product model on your face in real time during the try-on session.
• All processing happens on your device; face data is never recorded, stored, or transmitted to ebuds servers or to any third party. It is discarded immediately when the try-on session ends.
• Face data is never used for identification, authentication, advertising, or analytics purposes.

e) Technical and usage data

• IP address, device type, operating system, and app version.
• Connection/session logs (kept for a short period for security purposes).

f) Notifications

• To send you push notifications, a device-specific notification identifier (device token) is generated and shared with our notification infrastructure provider, Google Firebase Cloud Messaging.
• This token is stored in association with your account so that notifications can be delivered to you, and it is used solely for delivering notifications. If you do not grant notification permission, this data is not processed; you can revoke the permission at any time in your device settings. The token is deleted when you revoke the permission, uninstall the app, or delete your account.

g) Problem reports (diagnostic data)

• When you use the "Report a problem" feature in the app, a diagnostic package is sent together with your request so that we can resolve the issue: device model, iOS and app version, battery level, app logs, and your Eva settings. Your name and your device's name are not included.
• A transcript of your recent conversation is included only if you explicitly consent.
• These packages are used solely for debugging, are accessible to a limited number of authorized staff, and are deleted within 90 days at the latest.

2. Purposes of use

• To provide the Service and perform real-time translation.
• To provide the Eva voice assistant feature.
• To operate the video calling and AR try-on features.
• To manage your account and subscription.
• To ensure security and prevent abuse.
• To comply with legal obligations.

3. Third parties

• Google (Gemini API) — audio is processed for real-time voice translation and for generating Eva voice assistant answers.
• Google (Firebase Cloud Messaging) — delivery of push notifications.
• Hosting provider — the infrastructure the Service runs on.

We do not sell your data to third parties for marketing purposes. Face data is never shared with any third party.

4. Retention periods

• Account data: for as long as your account remains open.
• Call and assistant (Eva) audio, and call video: not permanently stored.
• Face data: never stored; it is processed on your device in real time and discarded immediately when the session ends.
• Notification token: for as long as the app is installed and notification permission is enabled.
• Problem report diagnostic packages: 90 days at most.
• Technical logs: for a limited period (30 days).
