Written by a solo developer and not legal advice; items marked like this (operator info, contact, jurisdiction) will be finalized before official publication. This English text is a convenience translation — in case of any discrepancy, the Korean version governs.

Article 1 (Purpose)

These Terms set out the conditions of use of the mobile application MailMail (the "Service") provided by solo developer operator name — TBD (the "Operator"), and the rights and obligations between the Operator and users.

Article 2 (Definitions)

  1. Service: the MailMail app running on iPhone and Apple Watch, and all incidental features.
  2. User: a person who agrees to these Terms and uses the Service.
  3. Pro (paid): the usage state in which the paid features of Article 6 have been purchased.
  4. Mail provider: an external mail service the user connects, such as Naver, Daum/Kakao, Gmail, Outlook, or generic IMAP.

Article 3 (Effect and amendment of the Terms)

  1. These Terms take effect upon posting in the app or at this URL.
  2. The Operator may amend these Terms within the bounds of applicable law and will announce the effective date and content in advance of changes. If a user disagrees with a change, they may discontinue use of the Service.

Article 4 (Content of the Service)

  1. The Service fetches mail from the mail providers a user connects and, using on-device AI (Apple's on-device model), summarizes it so it can be quickly reviewed and handled (read/archive, etc.) on Apple Watch.
  2. The handling of mail bodies and credentials follows the Privacy Policy.
  3. The Service does not provide composing, sending, searching, viewing attachments, or folder management in v1 (intended scope — watch inbox positioning). These may be expanded in future versions.

Article 5 (User obligations)

  1. Users must connect only mail accounts they are lawfully authorized to use.
  2. Users must comply with their mail provider's terms (for example, conditions for using app passwords).
  3. Users must not:
    • reverse-engineer, copy without authorization, or resell the Service;
    • place abnormal load on or attempt to compromise the Service or its integrated servers;
    • connect to or access another person's account or information without authorization.

Article 7 (Intellectual property)

Rights to the Service and its components (software, design, the trademark "MailMail") belong to the Operator. Rights to the mail data a user connects belong to that user.

Article 8 (Notice regarding AI summaries — important)

  1. The Service's summaries, to-do extraction, and priority judgments are generated automatically by AI and are not guaranteed to be accurate or complete.

  3. The Operator's liability is limited to the extent provided by applicable law.

Article 11 (Termination)
