개인정보 처리방침

Established: July 14, 2026 / Last revised: October 30, 2026

ProtoductAI, Inc. (the “Company”) establishes this Privacy Policy (the “Policy”) regarding the handling of users’ information in the iOS app “Morphy” (formerly named Sotto; the “App”). By using the App, you agree to this Policy.

1. Basic policy

The App’s core function is to suggest replies from a screenshot of a chat. In this process, the screenshot or image itself is never sent outside your device. Text recognition (OCR) of the image is completed entirely on your device, and only the text read by OCR is sent externally.

2. Information we collect

• Text read by OCR: Text extracted on your device from a screenshot. It is sent to the AI through our server in order to generate reply suggestions.
• Draft text and copied text: Draft text you enter when using “Tidy up”, tone conversion, translation or reply suggestions, and text you copy when you set the source to “Copied text”. It is sent to the AI through our server for processing.
• Device identifier (deviceId): An anonymous ID used to manage the limit on the number of generations per day and to manage the purchase status of Morphy Pro (as the RevenueCat user ID). It is stored in your device’s Keychain and remains even if you delete the App. Our server stores a usage record (such as the number of uses) for this ID. It is not linked to personal information such as your name, phone number or email address.
• Reply and conversion settings: Preset names (which may include a person’s name), writing-style settings, free-form instructions, and the instructions of intent chips and generation slots. They are sent to the AI through our server each time you generate reply suggestions or conversions. Your device’s language and time zone are also sent.
• Samples for voice learning: See “4. Analysis of LINE chat history” below.
• Crash and error information: To improve the App’s stability, we collect technical error logs through Sentry.
• Purchase information: The purchase and renewal status of Morphy Pro (via Apple / RevenueCat).

3. Information we do not collect

• The screenshot or image data itself (nothing is sent outside your device)
• Personal information tied to account registration (the App does not require sign-up)
• Recording of keystrokes on a server (except for the text sent when you tap “Tidy up”, tone conversion, translation or reply suggestions; see “5. About keyboard Full Access” below)
• Payment information such as credit card numbers (processed by Apple / RevenueCat; the Company does not collect it)

4. Analysis of LINE chat history

When you enable the “voice learning” feature, the LINE chat history file you specify is analysed. This analysis is completed on your device, and the LINE chat history file itself is never sent to an external server. Only samples of your own messages are saved for learning; the other party’s messages are never learned or saved. The result is saved on your device, in the “Preset for each person”, as reference data for your writing style. The saved examples of your messages (up to 10) are sent to the AI through our server as a style reference each time you generate reply suggestions or conversions with that preset.

5. About keyboard Full Access

The App’s keyboard requires you to “Allow Full Access” in iOS settings. This is a technical requirement of iOS for the network communication needed to generate replies with AI. Granting Full Access does not allow us to record or collect your keystrokes on a server. Only when you tap “Tidy up”, tone conversion, translation, reply suggestions or a reply from “Copied text” is the relevant text sent to the AI. Learning for kana-kanji conversion is stored only on your device.

6. Purposes of use

• Generating reply suggestions and tone-conversion suggestions
• Managing the usage limit of the free plan
• Investigating defects and improving quality
• Managing the purchase and subscription of Morphy Pro

We do not use the information we collect beyond the purpose of providing the App, such as for training or reusing AI models.

7. Disclosure to third parties and processors

We do not provide information to any third party other than the above (except when required by a legal disclosure request).

8. Retention period

Text sent via the server is not retained beyond what is necessary once the reply generation is complete. However, the AI providers we use as processors may retain it for a certain period under their own terms. The device identifier is kept while you continue to use the App, in order to manage the usage limit (it is stored in your device’s Keychain and remains even if you delete the App). Your presets (including the learned examples of your messages) and AI settings are stored in the shared Keychain on your device and remain even if you delete the App. To remove them, delete the presets in the App first.

9. Use by minors

The App is not limited by age, but minors should use it with the consent of a parent or guardian.

10. Changes to this Policy

This Policy may be revised without notice in response to changes in law or in the service. If there is an important change, we will notify you in the App or on this page.
