Privacy Policy

1. Scope

This Privacy Policy (this "Policy") describes how SEIWA Co., Ltd. ("we", "us") handles information we obtain through the AccuNote voice-note application and its related cloud services (collectively, the "Service").

2. Information We Collect

2.1 Account and authentication information

• Email address: used for sign-in via email verification code (we do not set or store passwords).
• Third-party sign-in information: when you sign in with Apple, Google, or Microsoft, the identifier, email address, and display name provided by that provider.
• Guest information: in guest mode (used without registering an email), only an anonymous identifier tied to your device.
• Profile information: display name (optional).

2.2 Content you create and store

• Audio recordings: microphone recordings and imported audio/video files.
• Transcripts, translations, and summaries: speech-recognition text, translation results, and AI-generated summaries and email drafts.
• Speaker information: speaker labeling and corrections.
• Marks and attachments: timestamped marks, comments, images, and other attached files.
• Custom vocabulary: terms you add to improve recognition accuracy.

2.3 Information collected automatically

• Usage logs: feature usage history and the duration of recognized audio (for billing and quota management).
• Access information: IP address and access timestamps.
• Device information: OS, app version, device type.
• Cookies and tokens: authentication tokens used to keep you signed in.

2.4 Billing information

Subscriptions (paid plans) are purchased and paid for through the Apple App Store or Google Play in-app purchase systems. Payment details such as credit card numbers are processed by those platforms; we do not obtain or store them. We only obtain the information necessary to manage your subscription status and usage quota.

3. How We Use Information

Purpose	Details
Service provision	Recording, speech recognition, translation, summarization, speaker diarization, and sync across devices
Content storage	Storing, displaying, and managing your notes (recordings, transcripts, etc.)
Subscription management	Checking plan status and managing usage quota (recognition time)

4. Disclosure to Third Parties and Subprocessors

We do not provide personal information to third parties except as required by law or with your consent. However, to provide the Service, we engage the following providers as subprocessors and have them handle the minimum necessary data.

Provider	Purpose	Data handled
Google LLC (Google Cloud / Gemini)	Speech recognition, translation, summarization, speaker diarization	Audio recordings, transcript text
Cloudflare, Inc.	Infrastructure, storage, database, CDN	Recordings and content, access information, usage logs
Apple Inc. / Google LLC	Sign-in authentication, in-app purchases	Authentication identifiers, subscription information
Amazon Web Services, Inc.	Email delivery (verification codes, etc.)	Email address

We require these providers, by contract or otherwise, to implement appropriate safeguards. Their processing is limited to the purpose of providing the Service.

5. Sharing and Collaboration

If you use the Service's workspace sharing feature, you can share your content (recordings, transcripts, etc.) with other users or with specified email addresses. Sharing is initiated by you, and recipients can access the content according to the permissions you grant (such as view or edit). Revoking a share withdraws the recipient's access.

6. Data Retention and Deletion

Data type	Retention
User content (recordings, transcripts, summaries, marks, etc.)	Retained until you delete it. Permanent deletion from the trash erases the audio, transcript, summary, and mark attachments.
Account information	Erased within a reasonable period after account deletion (except where retention is required by law).
Temporary processing data	Temporary files used for recognition are deleted after processing is complete.
Usage logs	Stored for a limited period and then erased.

When you upgrade from guest mode to a registered account, content you created as a guest is, in principle, carried over to the same account.

7. Cookies and Tokens

We use authentication tokens and cookies to keep you signed in and to provide the Service. If you disable them, some features of the Service may become unavailable.

8. Security Measures

To prevent unauthorized access, loss, alteration, or leakage of information, we implement safeguards including:

• Encryption in transit (HTTPS / TLS)
• Encryption of stored data
• Hashed storage of authentication tokens and API keys, and HttpOnly cookie protection
• Restricted and managed employee access
• Regular review of our security posture

9. Your Rights

You may request disclosure, correction, addition, deletion, or suspension of use of your personal information. You can also delete your content and your account from within the app at any time. To exercise these rights or for questions about how we handle personal information, please contact us at the address below. To verify your identity, please contact us from your registered email address.

10. Minors

If you are a minor, please use the Service with the consent of a parent or guardian.
