Deep Journal — Terms of Service
Last updated: April 20, 2026
These terms govern your use of the Deep Journal iOS and macOS apps ("the app"). By using the app, you agree to these terms. If you do not agree, please uninstall the app.
1. What the app is
Deep Journal is a personal journaling tool with optional AI-assisted reflection features. It is developed and distributed by Zian Meng as an independent developer.
2. What the app is NOT
- Deep Journal is not a medical device.
- Deep Journal is not therapy and is not a replacement for professional mental-health care.
- Deep Journal is not a crisis service. If you are in crisis or in danger:
- United States: call or text 988 (Suicide & Crisis Lifeline), or call 911 for emergencies.
- Other countries: contact your local emergency services or a crisis line in your country (see IASP directory).
- Any references in the app to psychological concepts, therapeutic frameworks, or clinically-inspired questionnaires are for self-reflection purposes only. They do not constitute diagnosis, assessment, or treatment, and must not be relied upon as such.
3. AI-generated content
Deep Journal's AI features are powered by third-party large language models (currently Google's Gemini). AI-generated summaries, reflections, patterns, and wellbeing estimates:
- Can be inaccurate, misleading, or entirely wrong ("hallucinations").
- Are not reviewed by clinicians or by the developer before being shown to you.
- Must not be treated as professional advice of any kind.
- Are generated based on the text you submit — which is sent to Google for processing (see the Privacy Policy for details).
You are responsible for how you act on AI-generated content.
4. Your responsibilities
- You must be at least 17 years old to use the app.
- You must not use the app in a way that violates applicable law.
- You must not attempt to reverse engineer, decompile, or interfere with the app's operation or security.
- You must not use the app to generate content that is illegal, that harms others, or that violates Google's Gemini API prohibited use policy.
5. Your content
Your journal entries, photos, voice notes, and related data remain your own. The app does not acquire ownership or any license to your content. It stores and, at your request, transmits your content for processing as described in the Privacy Policy.
6. Subscriptions and payments
The app may offer paid features via Apple's In-App Purchase system. Payments are handled by Apple under Apple's terms. Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period. You can cancel or manage subscriptions in your Apple ID settings.
7. Disclaimers
The app is provided "AS IS" and "AS AVAILABLE" without warranties of any kind, express or implied, including but not limited to merchantability, fitness for a particular purpose, non-infringement, accuracy, or uninterrupted availability.
The developer makes no warranty that:
- The app will meet your specific needs.
- The app will be free of errors or interruptions.
- Any results, patterns, insights, or suggestions generated by the app will be accurate, appropriate, or beneficial.
- The app will be compatible with any particular device or software version.
8. Limitation of liability
To the maximum extent permitted by applicable law, the developer shall not be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages — including but not limited to loss of data, loss of profits, emotional distress, or harm arising from reliance on AI-generated content — even if advised of the possibility of such damages.
The developer's total liability arising out of or relating to these terms or the app is limited to the greater of (a) the amount you paid to the developer for the app in the twelve (12) months preceding the event giving rise to the claim, or (b) one U.S. dollar ($1.00).
Nothing in these terms excludes or limits liability that cannot be excluded or limited under applicable law (for example, certain consumer rights).
9. Indemnification
You agree to indemnify and hold harmless the developer from any claims, damages, or expenses (including reasonable attorneys' fees) arising out of your misuse of the app or your violation of these terms.
10. Termination
You may stop using the app at any time by uninstalling it. The developer may suspend or discontinue the app, in whole or in part, at any time, without notice.
11. Changes to these terms
If these terms change, the "Last updated" date above will be updated. Material changes will also be surfaced in the app. Continued use after a change constitutes acceptance.
12. Governing law
These terms are governed by the laws of the jurisdiction in which the developer resides, without regard to conflict-of-law rules. Any dispute that cannot be resolved informally will be brought in the competent courts of that jurisdiction, unless mandatory consumer-protection law in your jurisdiction provides otherwise.
13. Severability
If any provision of these terms is held unenforceable, the remaining provisions remain in full force and effect.
