Privacy Policy

Last updated: 2026-10-03

Marujigi (the "Company") provides medication reminders, family schedule sharing and voice-phishing prevention for seniors in the Republic of Korea. This policy explains what information we collect, why, and how we protect it under the Personal Information Protection Act.

Information we collect

  • Mobile phone number (senior accounts) — used only for passwordless SMS sign-in. Stored encrypted (AES-256-GCM) and never displayed in plain text, even internally.

  • Email address (family/child accounts) — used for sign-in and account recovery.

  • What you say to Maru — the app does not record or transmit your voice. When you press the microphone button, your phone's built-in speech recognition converts your speech to text on the device, and only that text is sent to the Company, exactly as if you had typed it. The microphone is open only while you hold it on and closes when you release it. Depending on your phone settings, speech recognition may be processed by Apple or Google rather than on the device; that processing is governed by their respective privacy policies.

  • Text messages you submit for phishing checks — analyzed for fraud risk and stored encrypted.

  • Schedule and reminder information — entered by you or your family.

  • Location (senior accounts, with separate consent) — collected even when the app is not in use or is closed, so that connected family can check on the senior's safety and Maru can give local weather. Only the most recent location is stored, encrypted; no history is kept. It is shared only with connected family and can be turned off at any time in Settings.

The Company uses no advertising or cross-app tracking SDKs and does not sell personal information.

How we use information

  • To provide core features such as reminders, family links, phishing alerts and the voice assistant

  • To send registered schedule reminders and urgent phishing alerts to connected family as push notifications

  • To process subscription payments (family/child accounts only)

Seniors are informed in advance of what information is shared when a family link is made, and can stop sharing at any time by disconnecting the link.

Third parties and processors

  • Naver Clova — used only for text-to-speech (TTS), to turn Maru's written replies into speech. Your voice is never sent to Clova.

  • OpenAI API — used to understand your requests and assess phishing risk. Only text is sent, never audio.

  • Apple App Store / Google Play — in-app subscription payments on iOS and Android

  • Expo Push Notification Service and Firebase Cloud Messaging — delivery of push notifications (processes your device's push token)

Each provider processes information only to the extent needed for that function and may not use it for its own purposes.

International transfer of personal information

To provide the Service, the Company transfers personal information abroad as follows.

Recipient: OpenAI, L.L.C. · Country: United States · Items: your request text, text messages submitted for phishing checks · Method: transmission over the network · Purpose: understanding requests and assessing phishing risk · Retention: until the purpose of processing is fulfilled

This transfer is made only to the extent necessary to perform our contract with you and provide the Service. You may refuse the transfer except where required by law; however, refusing may limit use of the voice assistant and phishing detection features.

Sensitive information

To provide medication reminders, the Company treats health-related information you enter, such as medication names, as sensitive information under the Personal Information Protection Act. It is collected only with your separate consent, used only for medication reminders, and not provided to third parties. Where it is sent to OpenAI for voice-assistant processing, the international transfer provisions above also apply.

Retention period

We retain account information for as long as your account exists. Payment and transaction records are kept, regardless of account status, for the period required by the Act on Consumer Protection in Electronic Commerce and other applicable laws. For how to delete your account, see the account deletion page.

Destruction of personal information

Personal information whose retention period has expired or whose purpose has been fulfilled is destroyed without delay. Electronic files are permanently deleted in a non-recoverable way; paper records are shredded or incinerated.

Your rights

You may request access to, correction of, or deletion of your personal information at any time. To delete your account, do so directly in the app (Settings → Delete account) or send a request to help@marujigi.com.
