Terms of Service

Effective Date: April 19, 2026

Welcome to Cynosure, operated by A3RN LLC ("A3RN," "we," "us," or "our"). The Service is available only to users who are at least 21 years of age and residents of the United States. By creating an account or using the Cynosure application ("Service"), you agree to be bound by these Terms of Service ("Terms"). Your electronic acceptance of these Terms constitutes a legally binding agreement, equivalent to a handwritten signature. If you do not agree to these Terms, do not use the Service.

1. Account Creation

The Service is available only to individuals who are at least 21 years of age and residents of the United States. By creating an account, you represent and warrant that you are at least 21 years old and a U.S. resident. The Service is not intended for minors. If we learn that a user under 21 has created an account, we may terminate that account without notice or liability.

To create an account, you must use a valid email address. You may only create and maintain one account. Creating multiple accounts is prohibited and may result in termination of all associated accounts without notice.

You represent and warrant that all information you provide during account creation and use of the Service is accurate, current, and complete. Providing false, misleading, or fraudulent information — including misrepresenting your age, identity, or residency — constitutes a material breach of these Terms and may void your rights under this agreement, including any right to a refund or damages.

You are responsible for maintaining the security of your account credentials and for all activity that occurs under your account.

2. End-to-End Encryption & Recovery Phrase

Cynosure uses mandatory end-to-end encryption to protect your content. During account setup, you will receive a recovery phrase. This phrase is the only way to recover your encrypted data.

Important: Cynosure cannot access, decrypt, or recover your encrypted data. If you lose your recovery phrase, your encrypted data will be permanently unrecoverable. You are solely responsible for securely storing your recovery phrase. A3RN has no obligation to provide account recovery assistance, data recovery services, or technical support beyond the self-service features available in the app.

3. Subscription & Billing

Cynosure offers the following subscription tiers:

Free Trial: A3RN may offer a free trial period to new accounts at its discretion. Trial duration, features, and availability may vary and are subject to change without notice. Any free trial is provided "as is" without any warranties, service-level commitments, or support guarantees. A3RN may modify, limit, or terminate free trials at any time without notice or liability.

Basic Plan: Current subscription pricing is displayed at the time of purchase in the Apple App Store, Google Play, or on our website.

Enterprise Plan: Available for organizations with 100 or more users through offline billing. Pricing per the applicable order form. Contact us for details.

After your trial expires, your account enters read-only mode. You can still view your data and mark tasks as complete, but you cannot create or edit tasks, goals, or visions until you subscribe.

Automatic Renewal: Subscriptions auto-renew at the end of each billing period at the then-current rate until cancelled. How renewal and cancellation work depends on where you purchased the subscription:

Refund Policy: Refund paths differ by purchase channel:

4. Payment Processing

Payments for Apple App Store purchases are processed by Apple, and payments for Google Play purchases are processed by Google. A3RN does not receive, process, or store payment card details for those purchases.

Payments for web subscriptions (purchased at a3rn.com) are processed by Paddle.com Market Ltd. ("Paddle"). Paddle acts as the Merchant of Record for these purchases, meaning Paddle is the seller of record and is responsible for handling payment, applicable taxes, refunds, and chargebacks. Your purchase is also subject to Paddle's buyer terms, and your receipt will identify Paddle as the merchant. A3RN does not store payment card details; Paddle holds them under its PCI DSS compliance program.

Enterprise plans billed offline are invoiced directly by A3RN under the applicable order.

5. AI-Powered Features

Subscribers may opt in to AI-powered features including goal validation, activity suggestions, and SMART criteria analysis. These features are powered by third-party AI providers.

When you use AI features, the text of the specific item being analyzed (e.g., an activity or goal description) is sent to the AI provider. We minimize the personal data included in AI requests. You may manage AI feature preferences in your settings.

AI-generated suggestions, analyses, and recommendations are provided for informational purposes only and do not constitute professional, financial, medical, legal, or career advice. You should not rely on AI outputs as a substitute for professional judgment. A3RN makes no guarantees regarding the accuracy, completeness, or suitability of any AI-generated content.

6. Third-Party Services & Integrations

The Service may integrate with or rely on third-party services, including but not limited to payment processors, AI providers (Anthropic, OpenAI), and cloud infrastructure providers. A3RN expressly disclaims all representations, warranties, and liability relating to any third-party services. Your use of third-party services is governed by their respective terms and privacy policies. A3RN is not responsible for any data loss, service interruptions, or damages arising from third-party service failures, changes, or discontinuation.

A3RN does not endorse, guarantee, or assume responsibility for any third-party service, even if the Service provides a direct integration. You assume all risk associated with your use of third-party services in connection with the Service.

7. Acceptable Use

The Service is licensed for personal, non-commercial use only. You may not use the Service for any business, commercial, professional, or organizational purpose.

You agree not to:

Fair Use: A3RN reserves the right to impose reasonable usage limits on the Service. If your usage significantly exceeds normal patterns, we may throttle, suspend, or terminate your account without liability. We are not obligated to provide advance notice of usage limits or to maintain any particular level of capacity for your account.

8. Copyright Infringement (DMCA)

A3RN respects the intellectual property rights of others and expects users to do the same. In accordance with the Digital Millennium Copyright Act of 1998 ("DMCA"), we will respond to notices of alleged copyright infringement that comply with the DMCA and are properly submitted to our designated agent.

If you believe that content available through the Service infringes your copyright, please submit a written notification containing the following:

Send DMCA notices to: with the subject line "DMCA NOTICE."

Repeat Infringers: A3RN will terminate the accounts of users who are determined to be repeat infringers in appropriate circumstances.

9. Data Portability & Export

Cynosure provides a data export feature that allows you to download your data in JSON format through the app settings. Exported data is decrypted on your device before download.

Shared Teams: Content you contribute to a shared team owned by another user belongs to that team and its owner. Your data export includes only data from your personal workspace and shared teams that you own. Content you contributed to teams owned by other users is not included in your export, as it is the property of the team owner.

This feature is provided as part of the Service and may be modified or discontinued at any time in accordance with these Terms.

10. Account Termination

You may delete your account at any time. Upon deletion, all data in your personal workspace and shared teams you own is permanently deleted from our servers. Content you contributed to shared teams owned by other users is retained by the team owner with your author reference removed.

We may suspend or terminate your account if you violate these Terms or engage in activity that threatens the security or integrity of the Service.

Account Inactivity: We reserve the right to suspend or terminate accounts that have been inactive (no login) for an extended period. We may notify you at the email address on file before termination, but are not obligated to do so. After termination, all data associated with the inactive account will be permanently deleted.

Automated Enforcement: Account suspensions, terminations, and security enforcement actions (including fraud detection and abuse prevention) may be carried out by automated systems without human review. A3RN has no obligation to provide human review of automated decisions, and you waive any right to challenge the method by which such decisions are made.

11. Service Modifications & Discontinuation

A3RN reserves the right to modify, suspend, or discontinue the Service (or any part thereof) at any time, with or without notice, and without liability to you. A3RN is not obligated to notify you of changes or to maintain or support the Service indefinitely.

In the event of a permanent discontinuation, A3RN may provide advance notice to allow you to export your data, but is not obligated to do so.

Beta & Preview Features: A3RN may offer beta, preview, early access, or experimental features ("Beta Features"). Beta Features are provided "as is" without any warranty of any kind and may contain bugs that could cause system failures or data loss. A3RN has no liability or responsibility for any losses arising from your use of Beta Features. Beta Features may be discontinued at any time without notice and without entitling you to any compensation.

12. Limitation of Liability

To the maximum extent permitted by law, A3RN shall not be liable for:

You acknowledge that while Cynosure employs end-to-end encryption and industry-standard security measures, no system is completely secure. In the event of a security breach, A3RN's notification obligations are limited to those imposed by applicable law. A3RN shall not be liable for damages resulting from such a breach.

The Service is provided "as is" and "as available" without warranties of any kind, either express or implied, including but not limited to implied warranties of merchantability, fitness for a particular purpose, title, and non-infringement. A3RN does not warrant that the Service will be uninterrupted, error-free, or that any data stored will be preserved without loss or corruption.

Your subscription grants access to the Service as it exists at the time of use. No subscription fee guarantees the availability of any specific feature, functionality, or level of performance. Features may be added, modified, or removed at any time without prior notice and without entitling you to a refund.

Cynosure is a personal productivity tool only. It does not provide financial, legal, medical, or professional advice of any kind. You should not make financial or business decisions based solely on information presented in the Service. A3RN is not responsible for any financial losses, missed opportunities, or adverse outcomes resulting from your use of the Service or reliance on its features.

No Regulated Industry Use: The Service is not designed, intended, or authorized for use in connection with any regulated industry or high-stakes activity, including but not limited to healthcare, medical treatment planning, legal case management, financial portfolio management, tax preparation, insurance, real estate transactions, or any activity subject to professional licensing requirements. If you use the Service for any such purpose, you do so entirely at your own risk, and A3RN expressly disclaims all liability for any losses, damages, penalties, or regulatory consequences arising from such use.

TO THE MAXIMUM EXTENT PERMITTED BY LAW, A3RN SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, INCLUDING BUT NOT LIMITED TO LOSS OF PROFITS, LOSS OF DATA, LOSS OF BUSINESS OPPORTUNITIES, LOSS OF GOODWILL, FINANCIAL LOSSES, EMOTIONAL DISTRESS, OR COST OF SUBSTITUTE SERVICES, REGARDLESS OF WHETHER A3RN HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

YOUR SOLE AND EXCLUSIVE REMEDY FOR ANY DISSATISFACTION WITH OR DAMAGE ARISING FROM THE SERVICE IS TO STOP USING THE SERVICE AND, IF APPLICABLE, REQUEST CANCELLATION OF YOUR SUBSCRIPTION. YOU AGREE THAT NO OTHER REMEDY (INCLUDING BUT NOT LIMITED TO INJUNCTIVE RELIEF OR SPECIFIC PERFORMANCE) SHALL BE AVAILABLE TO YOU.

A3RN has no obligation to maintain, backup, or preserve your data beyond what is described in these Terms. While we employ reasonable measures to protect data stored on our servers, we do not guarantee the integrity, availability, or recoverability of any user data. A3RN does not review or verify user data for accuracy and assumes no responsibility for its contents.

You voluntarily assume all risk associated with your use of the Service. You acknowledge that data loss may occur due to software errors, hardware failures, encryption key loss, or other unforeseen circumstances. You are solely responsible for maintaining your own backups of any critical information.

13. Indemnification

You agree to indemnify, defend, and hold harmless A3RN LLC, its members, managers, officers, employees, and agents from and against any claims, damages, losses, liabilities, costs, and expenses (including reasonable attorneys' fees) arising out of or related to your use of the Service, your violation of these Terms, or your violation of any rights of a third party.

14. Dispute Resolution & Arbitration

Any dispute arising out of or relating to these Terms or the Service shall be resolved through binding individual arbitration, rather than in court, except that either party may seek injunctive or equitable relief in court for intellectual property disputes.

Class Action Waiver: You agree that any dispute resolution proceedings will be conducted only on an individual basis and not in a class, consolidated, or representative action. You waive any right to participate in a class action lawsuit or class-wide arbitration against A3RN.

If you wish to initiate arbitration, you must first send a written notice describing the dispute to our contact email. Both parties agree to attempt to resolve the dispute informally for at least 30 days before initiating arbitration.
