Terms of Service
Last updated: July 11, 2026
In short
These Terms of Service ("Terms") govern your access to and use of the Xboost website and service (the "Service"), operated by Alexandre Larzilliere ("Xboost", "we", "us"). By creating an account or using the Service, you agree to these Terms. If you do not agree, do not use the Service.
1. Eligibility
You must be at least 16 years old and legally able to enter into a binding agreement to use the Service. By using Xboost, you represent and warrant that you meet these requirements and that you hold an X (Twitter) account in good standing that complies with X's own terms.
2. Your account
You are responsible for maintaining the security of your account and for all activity that occurs under it. You agree to provide accurate information when signing in (via Google or email link) and to keep your contact details current.
3. The Service
Xboost helps you plan, generate, and auto-schedule posts to your connected X account. You may connect your X account so that we can publish or schedule content on your behalf.
- Xboost is an independent tool and is not affiliated with, endorsed by, or sponsored by X Corp. or Twitter.
- We use third-party artificial-intelligence providers to help draft content. AI can produce inaccurate, biased, or inappropriate output.
- We do not guarantee any specific reach, engagement, followers, or results. Growth depends on many factors outside our control.
- Availability may be affected by third-party platforms, APIs, or maintenance, and we may change, suspend, or stop parts of the Service at any time.
4. Acceptable use
You agree not to use the Service to:
- Violate any law, regulation, or the terms of any third-party platform (including X's rules and policies);
- Publish content that is unlawful, harmful, harassing, defamatory, infringing, deceptive, or otherwise objectionable;
- Impersonate another person or entity, or post content you do not have the right to publish;
- Spam, artificially inflate engagement, scrape data, or attempt to overwhelm or breach the Service or third-party systems;
- Resell, sublicense, or provide access to the Service to third parties unless explicitly allowed by your plan.
Xboost may suspend, throttle, or terminate access if we believe your use violates these Terms or threatens the Service.
5. Your content
You retain ownership of the content you create, upload, or publish through Xboost ("Your Content"). You grant Xboost a worldwide, non-exclusive licence to host, process, generate, format, and publish Your Content solely to operate the Service for you — for example by scheduling it to your X account.
You are solely responsible for Your Content and for any consequences of publishing it. You represent that you have all necessary rights to the content you post and that it does not infringe third-party rights.
6. AI-generated content
Drafts produced by the Service are suggestions generated by AI models. They may contain errors or misrepresent facts. You must review every post before it is published. Xboost is not liable for the content you choose to publish, and you assume full responsibility for it.
7. Payments, plans and credits
- Paid plans (such as Starter, Pro and Max) are billed in advance through our payment processor, Stripe. We do not store your full card details.
- Subscriptions renew automatically at the end of each billing cycle (monthly or yearly) until you cancel. You can cancel or manage your subscription from your account at any time.
- Credits included in your plan (free or paid) are tied to your account, are non-transferable, and may reset or expire according to your plan and our usage limits.
- Prices may change. Any change will take effect at the start of your next billing cycle following reasonable notice.
- Unless required by law, payments are generally non-refundable. If you believe you were charged in error, contact us and we will review your request.
8. Third-party services
The Service relies on third parties such as X (Twitter), Stripe, Google, email-delivery providers, AI providers, and hosting infrastructure. Their terms and policies apply to your use of their services, and they may change or restrict access at any time. Xboost is not responsible for the acts or omissions of these third parties.
9. Intellectual property
The Service, its branding, software, and design are owned by Xboost and protected by intellectual-property laws. We grant you a limited, non-exclusive, non-transferable licence to use the Service for your own purposes in line with these Terms.
10. Disclaimer of warranties
The Service is provided "as is" and "as available". To the fullest extent permitted by law, we disclaim all warranties, whether express or implied, including warranties of merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that the Service will be uninterrupted, error-free, or secure.
11. Limitation of liability
To the maximum extent permitted by law, Xboost shall not be liable for any indirect, incidental, special, or consequential damages, or for any loss of profits, data, or audience, arising from your use of, or inability to use, the Service. Our total liability for any claim is limited to the amount you paid us in the twelve (12) months preceding the claim.
12. Indemnification
You agree to indemnify and hold Xboost harmless from any claims, damages, or expenses arising from Your Content, your breach of these Terms, or your violation of any law or third-party rights.
13. Termination
You may stop using the Service and delete your account at any time. We may suspend or terminate your account or access if you breach these Terms or if we decide to discontinue the Service. Sections that by their nature should survive (including ownership, disclaimers, and liability) remain in effect after termination.
14. Changes to these Terms
We may update these Terms from time to time. If we make material changes, we will notify you (for example by email or in the Service). Your continued use of the Service after changes take effect means you accept the updated Terms.
15. Governing law
These Terms are governed by the laws of France, without regard to conflict-of-law principles. We will try to resolve disputes informally first; otherwise they will be brought before the competent courts of France.
