Terms of Service — DreamVoice (Yume no Koe)

Operator: Takahiro Nishinobu (individual)
Contact (Support Form): https://forms.gle/9eEJhVS64nKTxdgr8
Service Region: Global / Intended Use: Personal (consumer) use / Age: 13+ (a higher age requirement may apply depending on the applicable store age rating or local laws). Minors should use the Service with guardian consent.

1. Scope

These Terms of Service (“Terms”) govern your use of DreamVoice (“Service”). The Service is operated by Takahiro Nishinobu (the “Operator”). By using the Service, you agree to these Terms.

The Service is intended for users aged 13 or older. Users under 13 may not use the Service. Minors should use the Service with guardian consent. If a higher age requirement applies under the applicable store age rating or local laws, that requirement applies.

2. Service

The Service lets you record dreams and provides AI-generated text (e.g., analysis, supportive notes, symbols, Weekly Dream Letters). A Weekly Dream Letter generates a reflection for a target week based on Dream Voice results and dream entries from that period. Some features require internet access.

3. Authentication & Support ID

The Service may use anonymous identifiers (e.g., for recognizing a user across sessions). A Support ID shown in the app may be used for support purposes.

4. Usage Limits

The Operator may set usage limits for AI features. Currently, daily Dream Voice generation is limited to 2 times per user per day. Weekly Dream Letters can be created when the target week has at least two completed Dream Voice days and daily generation for that week has finished. Weekly Dream Letters may also be subject to concurrent creation or frequency limits.

5. AI Output Notice

  1. AI output, including daily Dream Voice and Weekly Dream Letters, is provided as general reference only and is not medical, psychological, legal, or other professional advice or diagnosis.
  2. The Operator does not guarantee accuracy, completeness, usefulness, or fitness for any purpose.
  3. You use AI output at your own judgment and responsibility.
  4. The Service does not provide emergency response. In urgent or dangerous situations, contact local emergency services or qualified professionals.

6. Prohibited Conduct

You must not:

If you breach these Terms, the Operator may restrict or suspend your use without prior notice and take necessary measures.

7. Intellectual Property & User Content

  1. Intellectual property rights in the Service (programs, design, trademarks, etc.) belong to the Operator or rightful owners.
  2. Rights to text and other material you input (“User Content”) remain with you or the rightful owner.
  3. You grant the Operator a non-exclusive, worldwide, royalty-free license to store, copy, transmit, analyze, and process User Content as necessary to provide, maintain, and improve the Service, including AI generation, Weekly Dream Letter generation, storage, redisplay, notifications, deletion, and support. This includes transmission, storage, and processing by OpenAI, Google Firebase, and other service providers necessary to provide the Service.
  4. AI-generated content (“AI Output”) may be used by you at your own responsibility. However, due to the nature of AI, identical or similar output may be generated for other users. The Operator does not guarantee the uniqueness, originality, or non-infringement of third-party rights of AI Output. Do not use AI Output in ways that infringe rights or violate laws.
  5. The Operator may use anonymized/aggregated statistics for analysis and improvement.

8. Data Deletion (Ending Use)

You can delete entries via in-app functions. When you delete a Weekly Dream Letter, that Weekly Dream Letter display is removed, but the individual dream entries and daily Dream Voice results used as sources remain unless separately deleted. If you delete an individual dream entry, an already generated Weekly Dream Letter may remain as a snapshot from the time it was generated. When you delete your account, device data and related server data will be removed (processing may take time). Logs retained by external services may remain for a certain period; see the Privacy Policy.

9. Changes / Suspension / Termination

The Operator may change, add, suspend, or terminate the Service. Significant changes or termination will be notified in a reasonable manner (in-app or web), except in emergencies.

10. Disclaimer

The Service is provided “as is.” The Operator disclaims warranties of completeness, usefulness, performance, or fitness for particular purposes. Except in cases of the Operator’s intentional misconduct or gross negligence, the Operator is not liable for damages (including communication failures, system issues, data loss, or AI output) to the extent permitted by law. The Operator is not responsible for third-party apps or services invoked by the Service.

11. Fees

The Service is currently free. Paid features (e.g., subscriptions) may be introduced later; conditions (price, cancellation, refunds, etc.) will be provided at launch.

12. Changes to Terms

The Operator may amend these Terms. Continued use after the amended Terms take effect constitutes acceptance of the amended Terms.

13. Governing Law & Jurisdiction

These Terms are governed by Japanese law. The Tokyo District Court will have exclusive jurisdiction as the court of first instance.
