These Terms of Service ("Terms") govern your access to and use of the Xhancer browser extension, xhancer.com, and related account, Premium, public-post viewing, download, analytics, and AI features (collectively, the "Service"). "Xhancer," "we," "us," and "our" refer to the provider of the Service.
By installing, accessing, purchasing, or using the Service, you agree to these Terms and our Privacy Policy. If you do not agree, do not use the Service.
If you use the Service for an organization, you represent that you have authority to bind that organization, and "you" includes the organization. Mandatory consumer rights that cannot lawfully be waived remain unaffected.
Xhancer is a local-first browser extension and companion website for the X/Twitter web experience. Current features may include:
Features may depend on your browser, X account, region, plan, third-party availability, and current product version. The current plan page and checkout screen describe the features, prices, duration, and limits offered at the time of purchase.
You must be at least 13 and meet any higher minimum age or legal-capacity requirement that applies where you live. If you are not old enough to enter into these Terms yourself, a parent or legal guardian must authorize your use where permitted by law.
Some features require an Xhancer account. You agree to provide accurate information, keep your credentials confidential, and promptly notify support@xhancer.com if you suspect unauthorized access. You are responsible for activity under your account except to the extent caused by Xhancer's breach of these Terms or applicable law.
You may sign in with email and password or through a supported third-party identity provider. Your relationship with that provider is separately governed by its terms.
One person or organization may not create or use multiple accounts to evade product limits, enforcement, or payment obligations.
Subject to these Terms, Xhancer grants you a limited, non-exclusive, non-transferable, non-sublicensable, and revocable license to install and use the Service for your personal or internal business purposes.
The extension requests access to X domains, Xhancer domains, and browser storage because those permissions are needed to modify the X interface, read and organize content available in your browser session, store your local workspace, authenticate with Xhancer, and use features you initiate. The extension does not grant you any ownership of X, third-party content, or Xhancer software.
You may not copy, sell, lease, sublicense, distribute, or commercially exploit the Service itself; remove proprietary notices; bypass technical restrictions; or reverse engineer the Service except where applicable law expressly allows it.
Xhancer is independent from X Corp. and is not endorsed by or affiliated with X/Twitter. X, Grok, Google, Stripe, DeepSeek, browser stores, and other third-party services have their own terms and policies.
The extension may make requests to X using your existing browser session to provide features such as sync, search, analysis, and interface enhancement. You are responsible for:
Third-party changes may interrupt or permanently disable parts of Xhancer. We do not control and are not responsible for third-party platforms, content, accounts, APIs, outages, restrictions, or enforcement decisions.
Most extension workspace data is stored locally in browser extension storage or IndexedDB, including remarks, tags, synced content, browsing-duration records, AI agents, agent memory, and saved reports.
You are responsible for maintaining any backup you need. Available export and backup tools may cover only the data types and formats shown in the product. Clearing browser data, resetting a browser profile, device loss, browser malfunction, or uninstalling the extension may permanently delete local data. Xhancer cannot restore local data that was never sent to or stored by Xhancer.
Do not use the extension as the only copy of information you cannot afford to lose.
The website viewer and downloader are intended for publicly available X posts. They do not authorize access to protected, private, deleted, restricted, or otherwise unavailable content.
You are solely responsible for ensuring that your viewing, downloading, exporting, copying, or use of content is lawful and permitted by the content owner, X's rules, and any applicable copyright, privacy, publicity, contractual, or other rights. Technical availability of a download or export option does not mean that Xhancer or the rights holder has granted you permission to reuse the content.
You must not use the Service to bypass access controls, remove rights-management information, infringe intellectual property, invade privacy, impersonate another person, or distribute unlawful content.
Xhancer offers AI-assisted drafting and analysis. Depending on the feature:
AI output is generated automatically and may be inaccurate, incomplete, offensive, outdated, or similar to content generated for others. Xhancer does not guarantee originality, factual accuracy, legality, availability, or fitness for any purpose.
You must review AI output before using or publishing it. You are responsible for your prompts, the output you choose to use, compliance with third-party AI terms, and any resulting post or action. Do not submit confidential information, regulated data, or third-party personal information unless you have the necessary authority and an appropriate basis to do so.
You may use output returned to you to the extent permitted by applicable law and third-party provider terms. Xhancer does not promise that output is eligible for copyright or free of third-party rights.
Xhancer may offer a Free plan and one or more paid Premium options. Free and Premium limits can differ for remarks, tags, synced accounts, analytics reports, AI agents, agent memory, and export formats.
We may adjust features or limits prospectively as the product changes. A material reduction to a paid fixed-term entitlement will not apply retroactively where prohibited by law. Promotional, beta, trial, or free features may be changed or discontinued at any time.
Attempts to manipulate local storage, requests, accounts, payment status, or software to bypass plan limits are prohibited.
Payments are processed by Stripe and supported payment partners. Prices, taxes, currency, plan duration, payment method, and renewal terms are shown before you complete checkout.
If checkout identifies a purchase as a subscription, you authorize recurring charges at the displayed interval until cancellation. You may cancel through the available Stripe billing portal or by following the account instructions. Unless the checkout or applicable law states otherwise, cancellation stops future renewal and Premium remains available until the end of the already-paid billing period.
Some payment methods, including an offered Alipay flow, may purchase a fixed month or year of Premium as a one-time payment rather than an automatically renewing subscription. The checkout screen controls if there is any conflict about renewal.
Failed, reversed, refunded, or disputed payments may result in delayed activation, suspension, or removal of Premium access. We may change prices for future purchases or renewal periods. For recurring subscriptions, we will provide any notice required by applicable law before a new price applies.
Except where a refund is expressly offered at checkout or required by applicable law, payments are non-refundable once Premium access is delivered. We do not promise a general seven-day refund period. To request a legally required or otherwise applicable refund, contact support@xhancer.com with your account email and transaction information. Stripe or the relevant payment provider may separately apply its dispute and refund procedures.
You must not use the Service to:
We may investigate suspected misuse and take proportionate action, including limiting features, suspending access, terminating an account, preserving relevant evidence, or reporting conduct where required by law.
You retain any rights you have in remarks, tags, agent instructions, memories, prompts, exports, and other content you create or submit ("Your Content").
You grant Xhancer a limited, worldwide, non-exclusive license to host, transmit, reproduce, and process Your Content only as necessary to provide, secure, troubleshoot, and comply with law in connection with the Service. This license ends when the relevant content is no longer reasonably needed, subject to backups, legal obligations, and third-party processing already initiated.
You represent that you have the rights and permissions necessary to provide Your Content and that doing so does not violate law or another person's rights.
If you voluntarily provide feedback or suggestions, you permit us to use them without restriction or compensation, provided we do not publicly identify you without permission.
The Service, including its software, design, branding, documentation, and original website content, is owned by Xhancer or its licensors and is protected by applicable intellectual-property laws. These Terms grant only the limited right to use the Service described above. No other rights are transferred to you.
X, Twitter, Google, Stripe, DeepSeek, and other names and marks belong to their respective owners.
Our Privacy Policy explains what information is stored locally, what is processed by Xhancer or third parties, and your available choices. By using the Service, you acknowledge that information will be handled as described there.
We may update the extension, change interfaces, add or remove features, impose reasonable limits, conduct maintenance, or discontinue all or part of the Service. We do not guarantee that the Service will always be available, compatible with every browser or X version, or free from errors.
Where reasonably practicable, we will provide notice before discontinuing a material paid feature. Emergency, security, legal, browser-store, or third-party platform changes may require action without advance notice.
You may stop using the Service at any time, uninstall the extension, cancel an eligible recurring subscription, and request account deletion by contacting support@xhancer.com.
We may suspend or terminate access if you materially or repeatedly violate these Terms, create security or legal risk, fail to pay applicable fees, misuse third-party platforms through the Service, or if we discontinue the Service. Where appropriate, we may first provide notice and an opportunity to cure.
Termination does not automatically create a refund right. Provisions that by their nature should survive—including payment obligations, intellectual-property provisions, disclaimers, liability limitations, and dispute provisions—will survive.
TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE." XHANCER DISCLAIMS IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT.
We do not warrant that the Service, AI output, analytics, exports, public-post data, media links, or third-party integrations will be accurate, complete, lawful for your intended use, uninterrupted, secure, or error-free. Nothing in the Service is legal, financial, medical, or other professional advice.
Some jurisdictions do not allow certain warranty exclusions, so parts of this section may not apply to you.
TO THE MAXIMUM EXTENT PERMITTED BY LAW, XHANCER AND ITS CONTRIBUTORS, AFFILIATES, AND SERVICE PROVIDERS WILL NOT BE LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR LOSS OF PROFITS, REVENUE, BUSINESS, GOODWILL, DATA, OR USE, ARISING FROM OR RELATED TO THE SERVICE.
TO THE MAXIMUM EXTENT PERMITTED BY LAW, XHANCER'S TOTAL LIABILITY FOR ALL CLAIMS ARISING FROM OR RELATED TO THE SERVICE WILL NOT EXCEED THE GREATER OF (A) THE AMOUNT YOU PAID TO XHANCER FOR THE SERVICE DURING THE 12 MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM OR (B) USD 50.
These limitations do not apply to liability that cannot lawfully be limited, including any non-waivable consumer rights. The limitations apply only to the extent permitted in your jurisdiction.
To the extent permitted by law, if you use the Service on behalf of a business or for commercial purposes, you will indemnify and hold harmless Xhancer and its contributors and affiliates from third-party claims, losses, and reasonable costs arising from your unlawful use of the Service, Your Content, or your material violation of these Terms or third-party rights.
This section does not apply to individual consumers where prohibited by law.
Before starting formal proceedings, please contact support@xhancer.com and describe the dispute so we can attempt to resolve it informally.
These Terms are governed by the law applicable to the Xhancer service provider, without overriding any mandatory protections provided by the law of your country of residence. Courts and dispute-resolution procedures with jurisdiction under applicable law may hear disputes. These Terms do not require arbitration or waive any right to participate in a class or representative action where such a waiver has not been separately and lawfully agreed.
If any provision is found unenforceable, it will be modified to the minimum extent necessary or severed, and the remaining provisions will continue. Our failure to enforce a provision is not a waiver. You may not assign these Terms without our consent; we may assign them as part of a reorganization, financing, merger, acquisition, or sale of the Service. We are not responsible for delay or failure caused by events beyond our reasonable control.
These Terms and the Privacy Policy are the entire agreement between you and Xhancer regarding the Service, except for additional terms presented for a specific feature or purchase.
We may update these Terms to reflect changes to the Service, providers, risks, or law. We will post the updated Terms and change the "Last updated" date. If a change materially affects an active paid service, we will provide additional notice when reasonably required. Changes apply prospectively unless applicable law permits otherwise.
If you do not agree to updated Terms, you must stop using the Service before they take effect. Continued use after the effective date constitutes acceptance where permitted by law.
