DUORANG

Privacy Policy

Effective date: August 11, 2026 · Last updated: August 11, 2026

Keepin Inc. ("we", "us") operates the Duorang mobile application ("the Service"). This policy explains what personal data we collect, why, who processes it and what rights you have.

Please note first — your conversations with Yuri or Minsu are never stored on our servers. They stay on your phone, and neither your spouse nor we can read them (Section 4).

This is an English translation provided for convenience. The Korean version is the governing text.

1. Why we process personal data

We process personal data only for the purposes below. If a purpose changes, we will ask for your consent first.

  1. Account creation and management — verifying you, identifying your account, keeping you signed in, recording your consent to these documents, preventing misuse, sending notices and answering enquiries
  2. Couple connection — connecting spouses through an invitation code, managing and ending that connection
  3. AI conversation — voice and text conversation with "Yuri" (wife users) or "Minsu" (husband users), speech recognition (STT) and speech synthesis (TTS)
  4. Couple chat with translation — sending messages, photos, videos and files, translating them into the reader's language, and read receipts
  5. Video calls with live translation — call setup (ring, accept, decline), media relay, real-time translated subtitles and dubbed audio
  6. Notifications — new message and incoming call alerts, and the daily reminder you schedule
  7. Operating and improving the Service — diagnosing errors, improving quality, handling support requests
  8. Paid features — verifying subscription payments and promotional codes, granting, maintaining and revoking the pass (the entitlement held by a couple), and handling payment enquiries and disputes

2. What we collect and how

We collect only what the Service needs.

2.1 When you sign up or sign in (depending on the method you choose)

MethodData collectedType
Phone numberPhone number, SMS verification recordRequired
Google accountGoogle account identifier, email address, name, profile picture (where provided)Required
Kakao accountKakao member number, nicknameRequired
All methodsInternal user identifier (UID), sign-up and sign-in timestampsRequired

We receive only the items listed above from the sign-in provider. We never collect the password of that account.

2.2 Data created while you use the Service

CategoryDataNotes
Profile Display name, role (wife/husband), language, interests, profile picture, couple code, sharing settings, self-introduction (age, MBTI, blood type, hobbies, interests) Required (picture, interests and self-introduction optional). Your self-introduction is used only in your conversations with Yuri or Minsu and is never shown to your spouse.
Consent record Version of the Terms and Privacy Policy you agreed to, and the time of agreement Required — the minimum record needed to evidence consent
Couple connection Invitation code, both user identifiers, your spouse's display name, connection time Required
Couple chat Message text and its translation, sender, sent and read timestamps, attached photos, videos and files with file names When used
Video calls Call request, accept and decline states with timestamps, participant identifier When used. The audio and video of the call itself is not stored.
Notifications Push token (FCM), notification settings When notifications are enabled
Location Approximate or precise location (latitude, longitude) Optional. This feature is disabled in the current version — no location is collected or transmitted. If it is enabled later we will ask for separate consent and it will default to off.
Payment and pass Purchase identifier issued by the app store (purchase token or transaction ID), payment platform (Google Play / App Store), product and plan identifier, subscription state, order number, pass expiry date, any promotional code entered and when it was granted When you use paid features. Card numbers and other payment details are handled by the app store; we never collect or store them.
Usage metric Total time spent talking, per day, in seconds When you use AI conversation. We record only how long you spoke, never what was said. It is stored on our servers so it survives reinstalling the app or changing phones. It is never shown to your spouse.
Device and operational data App version, OS version, device model, access time, request status and error codes, app crash logs and diagnostics Generated automatically. Crash and diagnostic data is used only to find the cause of errors and improve stability. Conversation and translation content is never written to server logs.

2.3 How we collect it

3. How AI features handle your data

The AI features (conversation with Yuri or Minsu, speech recognition, speech synthesis, chat translation, call subtitles and dubbing) are delivered by the AI providers listed in Sections 6 and 7, either through our backend or directly from the app.

4. Data that stays on your device only

The following never leaves your phone. It is not sent to our servers and is not available to your spouse.

You can view, edit and delete this data inside the app. Deleting the app or your account removes it from the device completely.

The app disables automatic backup. Even if you turn on a phone-level backup (such as Google backup), this data is not included, so it cannot be recovered and read by someone who shares your account. The trade-off is that your conversations and memories do not move to a new phone, because no copy exists on our servers.

Health data is never sent to our servers and is never shared with your spouse. The Service does not diagnose health conditions or provide medical advice.

5. Retention and deletion

We delete personal data as soon as the purpose is fulfilled. Electronic files are deleted irrecoverably; any printed material is shredded or incinerated.

We keep certain records for the periods required by Korean law:

These transfers are made under Article 28-8(1) of the Personal Information Protection Act, as processing and storage entrusted to provide the Service and improve user convenience, and are disclosed in this policy.

You may refuse international transfer, but in that case the core features — AI conversation, translation and video calls — cannot be provided. To refuse, contact us using the details in Section 14.

8. Sharing with third parties

We do not share your personal data with third parties beyond the purposes in Section 1, except:

9. What your spouse can see

Duorang is used by two partners, so the following is visible to your connected spouse:

By contrast, your conversations with Yuri or Minsu, your memories, your call subtitle history, your self-introduction, your usage metric and your health data are never made available to your spouse in any form.

Status sharing such as location may be offered in future. If so, it will default to off, only the items you switch on will be shared, and only while they are on. What is currently being shared is always shown in the app and you can switch it off at any time. The Service must not be used to monitor a partner.

10. Your rights and how to exercise them

You may at any time:

You can do most of this yourself in the "Me" tab of the app:

Because the couple chat is a shared space, deleting it when you close your account also removes the conversation from your spouse's screen.

Closing your account is not cancelling your subscription. If you subscribe, you must cancel separately in Google Play or App Store subscription settings for the charges to stop.

You may also make a request in writing or by email using the contact details in Section 14, and we will act without delay. Requests made through a representative require a letter of authority.

11. Users under 18

The Service is not available to anyone under the age of 18 and we do not knowingly collect their personal data. If we learn that we have, we delete it without delay.

12. App permissions

Optional permissions can be refused; only the related feature will be unavailable. You can change any permission in your phone settings at any time.
