Effective: October 2, 2026 (previous version effective September 23, 2026)
Darak Studio Co., Ltd. ("the Company") values the privacy of users ("Users") of the MammaLog service ("the App") and establishes this policy to comply with the Personal Information Protection Act of the Republic of Korea and related laws.
The App does not separately collect phone numbers or location data, and stores an email address only when the sign-in provider above passes it on.
The Company retains personal information for the duration of service use and destroys it without delay in the following cases.
As a rule the Company does not disclose personal information externally. The following are exceptions.

(China) | AI interpretation of spoken or typed logs, parenting-consultation answers, monthly report and feeding/sleep pattern analysis, translation | The log sentences and questions you speak or type, record types, times and amounts, baby age in months (no baby name or contact details are sent; anything you say in a sentence is passed on as is) | Per the processor's policy. The processor states that it may use the information it receives to train and improve its technology. |
| Railway Corp. (USA) | Server hosting and database operation | All information listed in section 1 | Until account deletion |
| Apple Inc. (USA) | Sign in with Apple authentication, in-app purchase processing, iOS push notification delivery (APNs) | Apple ID-based identifier, transaction ID, push notification token and notification text | Per Apple's policy |

(Tree-Nation) (Spain) | Tree gift — registering one real tree in your family's name and issuing a certificate for a completed care tree | Family name (shown on the certificate), the one-line letter you write yourself, an order identifier (email address, baby's name and contact details are not sent) | Per Tree-Nation's policy |
The Company does not put direct identifiers such as a baby's name or contact details into AI requests, and every transfer uses an encrypted (HTTPS) channel. The Company requires and supervises processors to apply protections equivalent to this policy.
DeepSeek Privacy Policy: https://cdn.deepseek.com/policies/en-US/deepseek-privacy-policy.html
You have the right to refuse the transfer of your personal information abroad. If you refuse, some features such as AI functions may be unavailable.
The Company provides AI features (parenting consultation, spoken logging and so on) under the Terms of Service and this policy, and does not show a separate data-transfer consent screen for them. The information in section 6 is sent to the processors when you use an AI feature, and also when an analysis built automatically from your records — such as a weekly note or monthly report — is generated. If you do not want this, do not use the AI features; the basic recording features keep working. To object to automatic analysis, or to ask questions or withdraw, contact the privacy officer.
This app is designed as a tool for caregivers of infants (parents, grandparents, carers). The Company does not collect personal information directly from children under 14. Information recorded about a baby (name, date of birth, care records) is treated as information entered by the caregiver.
This app shows banner ads and rewarded ads through Google AdMob. While loading and showing ads, AdMob (Google) may collect information such as an advertising identifier and device and app information directly from your device, and Google's explanation applies to that processing.
The users of this app are the caregivers who look after babies, not the babies. The app therefore does not flag its ad requests as child-directed, and the Company does not collect personal information directly from children under 14 (see Section 9).
You may exercise these rights in the app's settings, or in writing or by email to the privacy officer below. The Company will act without delay.
If you need to report or consult about a privacy violation, you may contact the following Korean authorities.
This policy applies from its effective date. Where content is added, removed, or corrected, we will give notice on this page at least 7 days before the change takes effect — or at least 30 days before, for changes that materially affect your rights.
