1. Acceptance of Terms

By using ExtensionHub, you agree to these Terms of Service. If you do not agree to these terms, please do not use our Site. We reserve the right to update or modify these terms at any time without prior notice. Your continued use of the Site constitutes acceptance of any changes.

2. Age Requirement

You must be at least 18 years old, or the age of majority in your jurisdiction, to use ExtensionHub or purchase a subscription. By using the Site, you represent that you meet this requirement.

3. Use of the Site

You agree to use ExtensionHub for lawful purposes only. You are prohibited from:

  • Attempting to gain unauthorized access to any portion of the Site
  • Transmitting any viruses, malware, or harmful code
  • Harassing, threatening, or abusing other users
  • Scraping, crawling, or extracting data without our prior written consent

4. Intellectual Property

All content on ExtensionHub, including text, graphics, logos, icons, and software, is the property of ExtensionHub, except where third-party icon or font libraries are used under their own license, and is protected by copyright and other intellectual property laws. You may not reproduce, distribute, modify, or create derivative works without our express written permission.

5. Subscriptions, Billing & Cancellation

Certain extensions offer a free trial period, after which continued access to premium ("Pro") features requires a paid Monthly Pro subscription. Subscription pricing is displayed at the point of purchase and may vary by extension category.

Subscriptions automatically renew on a monthly basis unless cancelled before the next billing date. You may cancel your subscription at any time through Gumroad, our third-party payment processor; cancellation will take effect at the end of the current billing period, and no partial refunds are issued for the remainder of a billing cycle unless otherwise required by law.

Core features of each extension remain free to use indefinitely, with or without an active Pro subscription, except where an extension's listing states otherwise.

6. Third-Party Links

Our Site may contain links to third-party websites or services that are not owned or controlled by ExtensionHub. We have no control over, and assume no responsibility for, the content, privacy policies, or practices of any third-party sites. We recommend reviewing the terms and privacy policies of any third-party sites you visit.

7. Third-Party Payment Processing

All payments and subscription billing are processed by Gumroad, a third-party payment processor, and are subject to Gumroad's own terms of service and privacy policy. ExtensionHub does not directly collect, store, or process your payment card information. License verification for Pro features is performed via a request to Gumroad's servers; no other transaction data is transmitted by ExtensionHub extensions except where explicitly stated in an individual extension's privacy disclosure.

8. Disclaimer of Warranties

The Site, all extensions, and all content provided on ExtensionHub are offered on an "as-is" and "as-available" basis. We make no warranties, expressed or implied, regarding the accuracy, reliability, or completeness of any content or calculation. Your use of the Site and any extension is at your own risk.

Important: We do not guarantee that any extension listed on ExtensionHub will meet your specific needs, that any calculation or alert is error-free, or that the Site will be uninterrupted or error-free.

9. Not Financial, Legal, or Tax Advice

ExtensionHub and its extensions are informational and computational tools only. Nothing on the Site or within any extension constitutes financial, investment, legal, tax, accounting, or insurance advice. Calculations, alerts, and outputs — including but not limited to trade execution grading, margin and tax threshold calculations, compliance checks, sanctions screening results, and regulatory deadline reminders — are estimates based on formulas and data sources believed to be accurate at the time of publication, and are provided for informational purposes only.

You should independently verify any calculation or alert before relying on it for a financial, legal, tax, trading, or business decision, and consult a qualified professional — such as a licensed broker, attorney, accountant, or compliance officer — for advice specific to your situation. ExtensionHub is not responsible for decisions made based on the output of any extension.

Important: Extensions related to trading, sanctions screening, tax thresholds, or regulatory deadlines (including but not limited to the Denied-Party Name Screener, Wash Sale Rule Tracker, and 1031 Exchange Deadline Tracker) are screening and estimation aids only. A result from any of these tools is not a legal determination, compliance guarantee, or substitute for professional due diligence.

10. Limitation of Liability

To the fullest extent permitted by law, ExtensionHub and its affiliates, directors, employees, and agents shall not be liable for any indirect, incidental, special, consequential, or punitive damages arising out of or related to your use of the Site or any extension. This includes, without limitation, damages for loss of profits, data, goodwill, or financial loss resulting from reliance on any calculation, alert, or output.

11. User Submissions

If you submit any content, feedback, or suggestions to ExtensionHub, you grant us a non-exclusive, royalty-free, perpetual, and worldwide license to use, modify, and distribute that content in connection with our Site. You represent that you have the right to submit such content.

12. Termination

We reserve the right to terminate or suspend your access to ExtensionHub at our sole discretion, without prior notice, for conduct that we believe violates these Terms of Service or is harmful to other users or the Site.

13. Indemnification

You agree to indemnify and hold ExtensionHub harmless from any claims, losses, damages, liabilities, and expenses (including legal fees) arising out of your use of the Site or any extension, your violation of these Terms, or your infringement of any third-party rights.

14. Governing Law

These Terms of Service shall be governed by and construed in accordance with the laws of the State of New York, United States, without regard to its conflict of law provisions. Any disputes arising under these Terms shall be subject to the exclusive jurisdiction of the state and federal courts located in New York, New York.

The ExtensionHub.app Standard

HOW EVERY EXTENSION IS BUILT

๐Ÿงช

Experience

Every extension is designed, built, and personally tested by one founder before it ships, and the library continues to grow with new tools added regularly.

๐ŸŽฏ

Expertise

Every calculation is documented in a full guide showing the exact formula and worked example — nothing runs as an unexplained black box.

๐Ÿ›️

Authoritativeness

Formulas are sourced from primary authorities, not guesswork — SEC Reg NMS execution-quality methodology, FXCM's own published contract specs, IRS thresholds, and OFAC's public screening list.

๐Ÿ›ก️

Trustworthiness

Most tools run entirely in your browser with no server-side processing of your data. Pricing, data handling, and limitations are stated plainly in every guide.

๐Ÿ‘‹ About Me — Muhiuddin Alam

Hello, I'm Muhiuddin Alam — an independent developer and the builder behind ExtensionHub.app, a growing library of single-purpose Chrome extensions for trading, Amazon selling, international trade, small business operations, and everyday consumer finance.

I build and maintain ExtensionHub.app, where every extension is built in-house, organized into problem-focused extensions, and the catalog continues to grow with new tools added regularly.

You'll also find my writing on:

Based in New York, I design, build, and test every extension myself before it ships — each one is built around a single job: solve one specific problem well, with transparent, verifiable calculations rather than a black box.

๐Ÿ” Find the Perfect Browser Extension

Discover single-purpose browser extensions across problem-focused extensions — trading, Amazon selling, international trade, small business, consumer finance, real estate, and more. New tools are added regularly, and every extension is built and tested by me personally before it ships.

๐ŸŒ About ExtensionHub.app

Single-Purpose Browser Extensions • Built In-House • Trading, Selling & Everyday Money Tools

ExtensionHub.app is a single-developer library of Chrome extensions, organized into problem-focused extensions, with new ones added regularly. Every extension is built in-house—not sourced or aggregated from other developers.

I am Muhiuddin Alam, the developer behind ExtensionHub.app. My approach is simple: build narrow, single-purpose tools that solve one specific problem well, instead of bundling unrelated features into a bloated all-in-one app you'll only half use.

Each extension is built around a real, specific audience — retail and forex traders, Amazon wholesale sellers and brand owners, import/export businesses, freelancers and small business owners, everyday shoppers, real estate investors, and content creators. Every extension shares one subscription, so you're never paying separately per tool.

Here's how every extension on ExtensionHub.app is actually built:

  • ๐ŸŽฏ One job each — every extension solves exactly one problem, with no bundled feature creep.
  • ๐Ÿงฎ Transparent calculations — formulas are based on public, verifiable methodology (like the same NBBO execution-quality math brokers use, or FXCM's own published contract specs), not a black box.
  • ๐Ÿ”’ Local-first data — most extensions run entirely in your browser with no server-side processing of your data; the only network call most tools make is an optional license check for Pro features.
  • ๐Ÿ’ต Free core, forever — every extension keeps its core features working for free after the 14-day trial ends. Only the deeper Pro features require a subscription.

From trading and risk tools to Amazon wholesale and brand protection, international trade compliance, small business operations, and everyday consumer finance — each extensions was built around a specific, real gap I found wasn't already well-served by existing tools.

With ExtensionHub.app, you install exactly the tool for the problem you actually have, understand exactly what data it collects (usually none beyond what stays in your own browser), and pay for one extension's Pro subscription instead of hunting down and paying for a dozen separate apps.
