Privacy Policy

This is an English translation of the Japanese Privacy Policy. If the two versions differ, the Japanese version prevails.

CROON (the “App”) turns the audio playing on your iPhone into speech and subtitles in your language. This policy explains what information the App collects, how it is used, where it is sent and how it is stored.

1. Information we collect

1.1 Audio that is playing

When you start dubbing, the App receives the audio playing on your iPhone through iOS screen sharing. It does not receive the screen video. When you stop dubbing, it stops receiving audio.

1.2 Microphone audio

The microphone is used only when you ask a question by voice.

1.3 Conversation content

The original text and its translation, the dubbed audio, your questions and their answers, and each conversation’s title and date.

1.4 Account information

The email address and identifier we receive from the service you sign in with (Apple, Google or your email address).

1.5 Purchase records

Your plan and App Store transaction identifiers. Payments are handled by Apple, and we never receive your card details.

1.6 Device, usage and error information

Device model, OS and App versions, a record of actions in the App, processing times, error and crash information, and a device identifier that links them.

1.7 Feedback

When you send feedback, we receive what you wrote and attached, together with the conversation content and audio from that moment and the information in 1.6.

1.8 What we do not collect

We do not collect location, contacts, your photo library, health information or advertising identifiers. The App does not track you and contains no third-party code for advertising or analytics.

2. How we use information

• To provide the App’s features, including dubbing, subtitles, answers to questions and history
• To improve quality and investigate problems
• To develop and train our own AI models that make the App’s recognition, translation and voices more accurate
• To measure usage and bill for it
• To respond to your inquiries
• To prevent fraud and abuse, and to comply with the law

We do not use your information for advertising and we do not sell it.

3. Service providers

The App runs on our servers and on outside services we engage.

• AI services such as speech recognition, translation and speech synthesis
• Cloud services for servers, data storage and email delivery
• Apple and Google for sign-in and payments

For dubbing, we send these providers the audio that is playing, parts of the original audio used to make a voice that resembles the speaker, and the conversation text. Providers handle data under their agreements with us and their own terms. Depending on the provider and its terms, it may keep the data it receives for a period of time or use it to improve its service.

Except as required by law, we do not share personal information with third parties other than these providers without your consent.

3.1 Providers outside Japan

Most of our providers are outside Japan, mainly in the United States. The United States has no comprehensive federal law equivalent to Japan’s Act on the Protection of Personal Information; personal information is protected by state laws (such as California’s CCPA) and sector-specific laws. Each provider takes security measures under its own terms and privacy policy.

Depending on how a request is routed, a provider in a country other than the United States may process it, and that country cannot always be identified in advance, because the route is chosen for each request.

For information on each country’s system, see the survey published by Japan’s Personal Information Protection Commission, Systems for the protection of personal information in foreign countries. To learn more about the destination countries or the providers’ measures, contact us at the address in Section 8.

4. Storage

So that you can use the App after reinstalling it or on another iPhone with the same account, we store conversation content and audio, together with the information in 1.6, on our servers linked to your account. We use this data for the purposes in Section 2.

We keep stored data for as long as those purposes require and delete what is no longer needed.

5. Security

Communication is encrypted. Access to stored data is limited to specific people and routes and requires authentication.

6. Your choices and rights

• Dubbing runs only when you start it. iOS always shows that screen sharing is on, and you can stop it at any time
• You can delete conversations in the App. Deleting your account deletes the account and the conversation history linked to it. You can ask us to delete other stored data at the address in Section 8
• You can ask us to disclose, correct, stop using or delete your personal information, and to disclose records of its provision to third parties. Contact us at the address in Section 8

7. Age

The App is not intended for anyone under 16.

8. Changes and contact

If we change this policy, we will update this page and announce important changes in the App.
