If you do not agree, do not use the app.

Important health disclaimer

ZYNA IS AN EDUCATIONAL AND JOURNALING TOOL. IT IS NOT MEDICAL CARE, PSYCHOTHERAPY, CRISIS SUPPORT, OR A CLINICAL DIAGNOSTIC TOOL. YOU ARE INTERACTING WITH AN ARTIFICIAL INTELLIGENCE SYSTEM, NOT A HUMAN BEING, LICENSED HEALTHCARE PROFESSIONAL, OR AUTONOMOUS PSYCHOTHERAPY AGENT.

• The app does not diagnose conditions or prescribe treatment.
• AI-generated content may be inaccurate or incomplete.
• If you are in crisis or may harm yourself or others, contact the 988 Suicide & Crisis Lifeline (US and Canada), 911, local emergency services, or a qualified professional immediately.

Eligibility

You must be at least 13 years old (or the minimum age required in your country) to use Zyna. If you are under 18, you should use the app with permission from a parent or guardian.

You are responsible for ensuring your use of the app complies with laws in your location.

Your account

• You may sign up with email and password, a one-time email code, Google Sign-In, or Sign in with Apple (where available).
• You are responsible for keeping your sign-in credentials secure and for activity under your account.
• When cloud sync is enabled, your Inbox and Reflections are encrypted on your device before being synced to our cloud servers. Email/password accounts use your sign-in password. Google, Apple, or email-code accounts choose one Reflections password. Reset it anytime by email if you forget.
• You must provide accurate information and notify us if you believe your account has been compromised.

You may sign out at any time. You may delete your account in Settings → Data & export → Delete account.

Subscriptions and billing

Zyna offers optional Premium features through Google Play subscriptions and equivalent stores where available (subscription status may also sync via RevenueCat when enabled).

• Billing is processed by Google Play (or the applicable app store), not directly by us.
• Free trials, introductory offers, renewal dates, and cancellation are managed in your store account under Subscriptions.
• Prices may change in accordance with store policies; we or the store will notify you where required.
• Premium is tied to your Zyna account after you sign in. If you subscribe before creating an account, you will be asked to sign up or log in to link your subscription.
• Refunds follow the applicable store’s refund policies. Contact the store for billing disputes; we can help with account linking issues at support@zynamind.com.

What you can and cannot do

You agree not to:

• Use the app for unlawful, harmful, or abusive purposes.
• Attempt to access other users’ data or our systems without authorization.
• Reverse engineer, scrape, or overload our services.
• Upload content that infringes others’ rights or contains illegal material.
• Misrepresent the app as professional therapy or emergency care.

We may suspend or terminate accounts that violate these Terms or pose a security risk.

Your content

You retain ownership of the thoughts, notes, and other content you create in Zyna.

By using AI features, you instruct us to process your submitted text only to provide the features you request. Requests are encrypted in transit; our servers decrypt transiently to call Google Gemini Enterprise, then discard plaintext. Synced Inbox and Reflections are stored encrypted — see our Privacy Policy.

You grant us a limited license to host, store, sync, and process your content as needed to operate the service. We do not sell your reflections.

AI features and assumption of risk

Reflections, insights, and related outputs are generated automatically and may contain errors. They are for personal reflection only. Always use your own judgment and seek professional help when needed.

You choose when to run AI analyses. You can adjust personalization settings in the app and export or delete your data as described in the Privacy Policy.

By using our generative AI features, you expressly acknowledge and assume the following risks:

• Hallucinations: AI can generate responses that sound plausible but are factually incorrect or incomplete.
• Emotional dependency: You acknowledge the risk of emotional attachment or psychological dependency on the AI.
• Lack of sentience: The AI does not possess human emotion, empathy, or sentience.
• Imperfect crisis detection: We utilize automated safety protocols designed to detect expressions of suicidal ideation and refer you to crisis services. These protocols are pattern-based and inherently imperfect. Zyna Mind Inc. does not assume a legal duty of care as a clinical provider, is not a mandated reporter, and cannot guarantee the system will detect every crisis, especially indirect expressions of distress.

Intellectual property

The app, its design, branding, and original materials are owned by Zyna Mind Inc. or our licensors. These Terms do not grant you rights to our trademarks or software except as needed to use the app.

Service changes and availability

We may update, improve, or discontinue features with reasonable notice where practical. We strive for reliable service but do not guarantee uninterrupted or error-free operation.

Maintenance, third-party outages (including Google Play, Google AI, RevenueCat, or hosting providers), or device issues may affect availability.

Disclaimer of warranties

TO THE FULLEST EXTENT PERMITTED BY LAW, ZYNA IS PROVIDED “AS IS” AND “AS AVAILABLE” WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS OR IMPLIED, INCLUDING FITNESS FOR A PARTICULAR PURPOSE OR NON-INFRINGEMENT.

Limitation of liability

TO THE FULLEST EXTENT PERMITTED BY LAW, WE AND OUR SUPPLIERS DISCLAIM LIABILITY FOR INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, INCLUDING LOSS OF DATA, LOSS OF PROFITS, PERSONAL INJURY, EMOTIONAL DISTRESS, OR PSYCHOLOGICAL HARM ARISING FROM YOUR USE OF THE APP.

OUR TOTAL LIABILITY FOR ANY CLAIM RELATING TO THE APP IS LIMITED TO THE GREATER OF (A) THE AMOUNT YOU PAID US FOR PREMIUM IN THE 12 MONTHS BEFORE THE CLAIM, OR (B) USD $50, EXCEPT WHERE LAW REQUIRES OTHERWISE.

Some jurisdictions do not allow certain limitations; in those cases, our liability is limited to the maximum permitted by law.

Indemnity

You agree to indemnify and hold us harmless from claims arising out of your misuse of the app or violation of these Terms, except where caused by our gross negligence or willful misconduct.

Dispute resolution and arbitration

How disputes are resolved. Most disputes are resolved by binding individual arbitration seated in Toronto, Ontario. Court lawsuits are allowed only in the limited cases below, and then only in the courts described under “Governing law and exclusive venue.”

Mandatory binding arbitration. Except for the limited exceptions below (or where you validly opt out), any dispute, claim, or controversy arising out of or relating to these Terms or your use of the app will be resolved by final and binding individual arbitration. The seat (legal place) of the arbitration is Toronto, Ontario, Canada. The arbitration is governed by the Arbitration Act, 1991 (Ontario) or, if it applies, the International Commercial Arbitration Act, 2017 (Ontario). Proceedings will be conducted in English. The arbitrator may conduct hearings by video or telephone where appropriate.

Class action waiver. To the fullest extent permitted by law, you waive any right to bring or participate in class, collective, consolidated, or representative actions. If a court finds this waiver unenforceable as to a particular claim, that claim (and only that claim) may proceed in court on an individual basis under the venue rules below, and not in arbitration.

30-day opt-out. You may opt out of this arbitration agreement by sending written notice to support@zynamind.com within 30 days of first accepting these Terms. Your notice must include your name, the email associated with your account (if any), and a clear statement that you wish to opt out of arbitration. If you opt out, disputes that would otherwise have been arbitrated are instead resolved exclusively in the courts described under “Governing law and exclusive venue.”

Small claims and injunctive relief. Either party may bring an individual action in a small claims court of competent jurisdiction in Toronto, Ontario (or another Ontario small claims court that has jurisdiction) for qualifying disputes, or seek temporary injunctive or other equitable relief in the courts of Toronto, Ontario to protect intellectual property or unauthorized access to the service, without waiving arbitration for other claims.

Enforcement of awards. Judgment on an arbitral award may be entered, and applications to assist, enforce, or set aside an award may be brought, in the courts of Toronto, Ontario, as permitted by applicable Ontario arbitration law.

Governing law and exclusive venue

Governing law. These Terms are governed by the laws of the Province of Ontario and the federal laws of Canada applicable therein, without regard to conflict-of-law principles, except where mandatory consumer-protection or other laws in your place of residence cannot be waived (including, where applicable, for consumers residing in Québec).

Exclusive court venue. Subject to the arbitration agreement above and to any non-waivable legal rights, you agree that any lawsuit, court proceeding, or other judicial action against Zyna Mind Inc. arising out of or relating to these Terms or your use of the app may be brought only in the federal or provincial courts located in Toronto, Ontario, Canada, and you irrevocably submit to the exclusive jurisdiction and venue of those courts. The same venue applies if you opt out of arbitration, if arbitration is found unenforceable for a claim, or for the limited court exceptions described above.

Changes to these Terms

We may update these Terms from time to time. We will post the updated version at https://zynamind.com/terms and update the “Last updated” date. Continued use after changes means you accept the updated Terms.
