Terms of Service & Licensing

Last Updated: January 2026

By installing, accessing, or using the ChatWall Browser Extension or ChatWall Box (collectively, the "Service"), you agree to be bound by these Terms of Service. If you do not agree, do not use the Service.

1. Licensing Structure

ChatWall operates under a hybrid licensing model designed to ensure transparency, security, and sustainability.

A. ChatWall Extension & ChatWall Sandbox

The ChatWall Extension and ChatWall Sandbox are provided under a restrictive Source Available license.

• Audit Rights: You are granted the right to view and inspect the source code for security auditing and transparency purposes.
• Restrictions: Redistribution, repackaging, or publication of this software on any application store or browser platform (including but not limited to Google Chrome, Chrome Web Store, Microsoft Edge, Edge Add-ons, Mozilla Firefox, Firefox Add-ons, Apple Safari) without written consent from StarObject S.A. is strictly prohibited. You may not use this code to create a competing commercial product.
• License Check: Usage is subject to a valid license (Free or Pro), verified via an online check. Bypassing this mechanism is a violation of these terms.

B. ChatWall Box (On-Premise)

The On-Premise solution is available for Enterprise clients upon approval.

• Access & Deployment: Access to the binaries, Docker images, and installation procedures is granted at the sole discretion of StarObject S.A. The specific method of deployment (e.g., managed hosting or self-hosted) will be defined in your specific commercial agreement or quote.
• Frontend Interface: Upon delivery, the frontend code component is provided under the MIT License, allowing you to modify and integrate it into your internal workflows.
• Backend Engine: The backend component is Proprietary Commercial Software. It is licensed to you, not sold. You are strictly prohibited from redistributing, reverse-engineering, decompiling, or creating derivative works of the backend components without express written permission.

2. Subscriptions, Payments, and Taxes

A. Billing and Payments

Payments for Premium/Enterprise plans are processed securely by our third-party partner, Stripe. StarObject S.A. / ChatWall does not store full credit card details. By subscribing, you authorize us (via Stripe) to charge your payment method for the agreed amount on a recurring basis (monthly or annually) until cancellation.

B. Taxes (VAT) & Pricing Display

Consumers (B2C): For customers located in the European Union acting as consumers, prices displayed generally include the applicable Value Added Tax (VAT) of your country of residence, in accordance with EU regulations (OSS scheme).

Businesses (B2B): For business customers providing a valid VAT ID, the Reverse Charge mechanism applies. In this case, the VAT rate is set to 0%. You will be charged the net price of the subscription without the addition of VAT.

Clarification: The application of the Reverse Charge mechanism removes the tax collection requirement but does not constitute a discount on the base price of the service. The net amount payable remains the same.

Final Calculation: The final amount, including the specific tax rate applicable to your location and legal status, will be calculated and displayed by Stripe at checkout before payment confirmation.

C. Price Changes

We reserve the right to modify pricing. Active subscribers will be notified via email at least 30 days before any price change takes effect.

3. Cancellation and Right of Withdrawal

A. Subscription Cancellation

You may cancel your subscription at any time via the "Manage Subscription" portal provided in the extension or on our website. The cancellation will take effect at the end of the current billing period. No refunds will be issued for the remaining days of a period already started.

B. Waiver of Right of Withdrawal (EU Consumers)

By purchasing a ChatWall subscription, you acknowledge that you are purchasing digital content that is accessible immediately. Therefore, you expressly waive your right of withdrawal (the 14-day cooling-off period under EU Consumer Law) once the service has been activated.

4. Third-Party Independence (OpenAI / ChatGPT)

A. No Affiliation

ChatWall is an independent software developed by StarObject S.A. It is not affiliated, endorsed, or sponsored by OpenAI, Microsoft, or Google.

B. Service Interruptions due to Third Parties

ChatWall functions by overlaying features on third-party websites (e.g., https://www.google.com/search?q=chatgpt.com). We are not responsible for service interruptions caused by changes to these third-party websites (e.g., HTML structure updates). While we strive to update our extension rapidly in such events, we cannot guarantee 100% uptime.

C. Account Safety

You remain solely responsible for your use of third-party AI platforms. StarObject S.A. / ChatWall shall not be liable for any account suspension, ban, or restriction imposed by OpenAI or other providers resulting from your use of browser extensions.

5. Data Privacy & Local Processing

ChatWall is designed with a "Privacy First" architecture.

• Local Processing: Text masking and PII detection occur locally on your device. Your prompt content is not sent to StarObject S.A. / ChatWall servers. Masked data and token mappings are ephemeral — they exist only during your active session and are wiped when the browser is closed. Custom favorite terms, however, are stored locally in your browser (base64 encoded) to persist across sessions. They are not synced to the cloud. Warning: As favorites are stored locally, there is a risk on public computers or if your device is compromised. Do not add sensitive data to favorites if you are not confident in your device's security.
• Account Data: We only retain necessary account information (Email, License Key, Stripe Customer ID) to manage your subscription.

Please refer to our Privacy Policy for full details.

6. Disclaimer of Warranties

The software is provided "AS IS", without warranty of any kind, express or implied. While ChatWall is designed to reduce the risk of sensitive data exposure using advanced algorithms (Regex, NLP, Heuristics), StarObject S.A. cannot guarantee 100% detection of all sensitive entities in all contexts. The user remains responsible for verifying data before submission to AI tools. We do not warrant that the software will be error-free or uninterrupted.

7. Limitation of Liability

To the maximum extent permitted by applicable law, in no event shall StarObject S.A. be liable for any indirect, incidental, special, consequential, or punitive damages, including but not limited to loss of profits, data, use, or goodwill, arising out of your use or inability to use the Service.

In any case, StarObject S.A.'s aggregate liability for all claims relating to the Service shall not exceed the amount paid by you to StarObject S.A. during the twelve (12) months immediately preceding the event giving rise to the claim.

StarObject S.A. shall not be held liable for security vulnerabilities arising from third-party components outside its reasonable control, including but not limited to browser engines, operating systems, JavaScript runtime environments, or upstream open-source dependencies ("Supply Chain Attacks"), provided that StarObject S.A. publishes corrective patches as soon as reasonably practicable after becoming aware of such vulnerabilities.

8. Governing Law and Jurisdiction

These Terms shall be governed by and construed in accordance with the laws of the Grand Duchy of Luxembourg. Any dispute arising out of or in connection with these Terms shall be subject to the exclusive jurisdiction of the courts of Luxembourg City.
