• Encourages, congratulates, and offers progressive hints

Article 4 — Available Brain Coaches

Coach Assist AI is integrated into DYNSEO's full ecosystem of culturally adapted brain coaches. Each coach speaks the local language and offers content tailored to its target audience and culture:

The Coach Assist AI feature operates identically across all coaches: same architecture, same privacy guarantees, same on-device processing — only the language, voice, and cultural references change.

Article 7 — Payment Terms

Payments are secure and processed by official platforms (App Store, Google Play) or by our certified payment provider. Prices are shown in euros, including VAT where applicable. DYNSEO reserves the right to change pricing at any time; new prices apply to new subscriptions and renewals only, with no retroactive effect on active subscriptions.

Article 8 — Right of Withdrawal

In accordance with EU consumer law (Directive 2011/83/EU) and Article L.221-28 of the French Consumer Code, the User acknowledges that by immediately activating Coach Assist AI upon subscription, they expressly waive their 14-day right of withdrawal for digital content supplied without a tangible medium and whose performance has begun with their explicit consent.

The User may nevertheless cancel their subscription at any time from within the application, free of charge, with cancellation taking effect at the end of the current billing period.

Article 9 — Privacy and Data Protection

9.1 Locally Processed Data Only

Coach Assist AI runs on a 100% local conversation architecture. This means:

• No voice recording is transmitted to our servers
• No text transcription of exchanges is kept by DYNSEO
• No content analysis of conversations is performed by DYNSEO
• No profiling based on conversations is carried out

9.2 Automatic Deletion at Each Session

Each voice session is independent and ephemeral:

• When the application is closed, the conversation is automatically deleted
• The next time the app opens, Coach Assist AI starts a fresh conversation, with no memory of past exchanges
• No trace of the conversation is synchronized or saved

9.3 Minimal Data Used by the Coach

To personalize the exchange, Coach Assist AI accesses only:

• The Player's nickname or first name (entered when the profile is created)
• The Player's list of favorite games

These two pieces of information are the sole basis for personalization and remain stored locally on the device. No other personal data (address, health status, medical history, etc.) is used by the Coach.

Article 10 — On-Device Processing and Session Lifecycle

The lifecycle of a conversation strictly follows these steps:

1. Application opens: The Coach launches and accesses the nickname and favorite games (local data only)
2. Voice session: Real-time exchanges happen on the device
3. Application closes: The conversation is automatically erased — no trace kept
4. Next session: The Coach starts from scratch, with no memory of previous sessions

Article 11 — GDPR Compliance

DYNSEO, as a French company, strictly applies the General Data Protection Regulation (GDPR — EU Regulation 2016/679) as well as the French Data Protection Act. Our data processing has been declared to the French Data Protection Authority (CNIL) since June 11, 2013, under registration number 1679021.

11.1 Data Collected by DYNSEO (excluding conversations)

For account and subscription management, DYNSEO collects:

• Email address (account creation, service communications)
• Account holder's first and last name (billing)
• Payment data (handled by our payment provider, never stored by DYNSEO)
• Minimal technical data (device type, OS version) for proper operation

11.2 Beta Phase Note

During the Coach Assist AI beta testing phase only, anonymized usage logs may be collected to improve the system (activation events, error logs, response time metrics). No conversation content is included in these logs. By participating in the beta program, you consent to this temporary log collection. You may withdraw from the beta program at any time by contacting us. Once Coach Assist AI exits beta, only the standard local processing described above will apply.

11.3 Your Rights

Under GDPR, you have the following rights:

• Right of access to your personal data
• Right to rectification
• Right to erasure ("right to be forgotten")
• Right to restrict processing
• Right to data portability
• Right to object to processing
• Right to withdraw consent at any time

To exercise these rights, contact us at: contact@dynseo.com

11.4 Hosting

Account management technical data is hosted on French servers (OVH) within the European Union. DYNSEO does not transfer your personal data outside the EU without appropriate safeguards (Standard Contractual Clauses, adequacy decisions). During the beta phase, certain AI processing components may involve data transfers outside the EU to our AI service providers, with appropriate safeguards in place.

11.5 Complaints

You have the right to lodge a complaint with the CNIL (www.cnil.fr) or with your local data protection authority if you believe your rights are not being respected.

Article 12 — User Obligations

The User agrees to:

• Use the Service in accordance with its purpose (cognitive stimulation, playful accompaniment)
• Not attempt to circumvent the AI message limits
• Not use the Service for unlawful, fraudulent, or harmful purposes
• Not attempt to reverse-engineer the Service or extract the underlying AI model
• Supervise, as a parent or caregiver, the use of the Service by minors or vulnerable persons

Article 13 — Service Limitations

13.1 Beta Status

Coach Assist AI is currently in beta. Updates, fixes, and improvements are deployed regularly. Temporary service interruptions may occur.

13.2 Functional Limitations

• The Coach is not a healthcare professional: it does not diagnose, prescribe, or replace a doctor, speech therapist, or therapist
• The Coach may make errors or imperfect rephrasings — it is a generative AI tool and not a medical authority
• In a medical or psychological emergency, contact emergency services immediately or a qualified professional

Article 14 — Liability

DYNSEO uses all reasonable means to ensure the availability, quality, and security of the Service. However, DYNSEO's liability cannot be engaged:

• For interruptions due to network outages, maintenance, or force majeure
• For non-compliant use of the Service by the User
• For indirect damages (loss of opportunity, abstract moral prejudice, etc.)
• For consequences of decisions made by the User based solely on Coach interactions

DYNSEO's total liability, all causes combined, is limited to the amount paid by the User over the previous 12 months.

Article 15 — Intellectual Property

All elements of the Service (code, design, content, brands COCO, SCARLETT, CLINT, SOFIA, ROBERTO, CARMEN, FERNANDO, ANNELIES, ZHIQU, IQU, JOE, EDITH, DYNSEO, logos, synthetic voices, Coach phrasings, cultural adaptations) are the exclusive property of DYNSEO or its partners. Any reproduction, representation, modification, or exploitation, in whole or in part, without prior written authorization is strictly prohibited and constitutes infringement under the French Intellectual Property Code and applicable international IP laws.

DYNSEO reserves the right to suspend or terminate access to the Service in case of:

• Non-payment
• Violation of these Terms
• Fraudulent or abusive use of the Service
• Decision to discontinue the Service (with reasonable notice and pro-rata refund)

Article 17 — Modification of the Terms

DYNSEO reserves the right to modify these Terms at any time. Users will be notified of any substantial change by email or in-app notification at least 30 days before the new terms take effect. Continued use of the Service after that date constitutes acceptance of the new terms.

Article 18 — Mediation and Amicable Resolution

In the event of a dispute, the User is invited to first contact our customer service at contact@dynseo.com to seek an amicable resolution. Failing agreement, consumer Users may turn free of charge to the competent consumer mediator or to the European online dispute resolution platform: https://ec.europa.eu/consumers/odr.

Article 19 — Governing Law and Jurisdiction

These Terms are governed by French law. Any dispute relating to their interpretation or performance shall, failing amicable resolution, be submitted to the competent courts of Paris, subject to mandatory consumer protection rules applicable in the User's country of residence.
