1. Acceptance of Terms

By accessing or using FBA Prep Checker ("the Service"), including our website, API, and Chrome extension, you ("User," "you," or "your") agree to be bound by these Terms of Service ("Terms"). If you are using the Service on behalf of an organization, you represent and warrant that you have the authority to bind that organization to these Terms. If you do not agree to these Terms, you must immediately stop using the Service.

2. Description of Service

FBA Prep Checker is a software tool that provides Amazon FBA sellers with prep requirement information as a reference. The Service allows you to look up ASINs and receive guidance on labeling, poly-bagging, bubble-wrapping, and other prep requirements based on publicly available Amazon FBA data. The Service is delivered via a web application and a Chrome browser extension.

3. Disclaimer of Accuracy

IMPORTANT NOTICE

THE SERVICE PROVIDES GUIDANCE BASED ON PUBLICLY AVAILABLE AMAZON FBA PREP REQUIREMENTS AND IS OFFERED ON AN "AS-IS" AND "AS-AVAILABLE" BASIS. FBA PREP CHECKER DOES NOT GUARANTEE THE ACCURACY, COMPLETENESS, OR TIMELINESS OF ANY INFORMATION PROVIDED. AMAZON MAY CHANGE ITS REQUIREMENTS AT ANY TIME WITHOUT NOTICE. YOU ARE SOLELY RESPONSIBLE FOR VERIFYING ALL PREP REQUIREMENTS THROUGH AMAZON SELLER CENTRAL BEFORE SHIPPING INVENTORY. WE ARE NOT AFFILIATED WITH, ENDORSED BY, OR SPONSORED BY AMAZON.COM, INC. OR ANY OF ITS AFFILIATES.

4. User Accounts

  • Accept responsibility for all activities that occur under your account.
  • Notify us immediately at yu@anyu.dev of any unauthorized access or security breach.

We reserve the right to suspend or terminate accounts that we reasonably believe are being shared or used in violation of these Terms.

5. Subscription Plans and Billing

  • Free Tier: The Service offers a limited free tier with a capped number of lookups per calendar month. Free tier features and limits may change at our discretion.
  • Paid Plans: Paid subscriptions ("Starter" and "Pro") provide additional features and higher or unlimited lookup quotas as described on our Pricing page.
  • Automatic Renewal: Paid subscriptions automatically renew at the end of each billing cycle (monthly) unless cancelled before the renewal date. You authorize us to charge the payment method on file for each renewal period.
  • Price Changes: We may change subscription prices upon 30 days' notice. Price changes take effect at the start of your next billing cycle following the notice period. Continued use after a price change constitutes acceptance of the new price.
  • Cancellation: You may cancel your subscription at any time through Stripe's customer portal or by contacting us. Cancellation takes effect at the end of the current billing period. No partial refunds are issued for unused time within a billing period, except as described below.
  • 30-Day Money-Back Guarantee: New paid subscriptions and plan upgrades include a 30-day money-back guarantee. If you are not satisfied within 30 days of initial purchase or upgrade, contact us for a full refund of that billing period. This guarantee applies once per customer per plan.
  • Failed Payments: If a payment fails, we may retry the charge and/or suspend your access to paid features until payment is successfully processed. We are not responsible for any fees your financial institution may impose.

12. Dispute Resolution and Arbitration

Binding Arbitration: Any dispute, controversy, or claim arising out of or relating to these Terms or the Service shall be resolved by binding arbitration administered by the American Arbitration Association ("AAA") under its Consumer Arbitration Rules, rather than in court. Arbitration shall take place in the State of California, United States, or at such other location as the parties mutually agree.

Class Action Waiver: YOU AND FBA PREP CHECKER AGREE THAT EACH PARTY MAY BRING CLAIMS AGAINST THE OTHER ONLY IN YOUR OR ITS INDIVIDUAL CAPACITY, AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY PURPORTED CLASS, CONSOLIDATED, OR REPRESENTATIVE ACTION. The arbitrator may not consolidate more than one person's claims and may not preside over any form of class or representative proceeding.

Small Claims Exception: Notwithstanding the above, either party may bring an individual action in small claims court for disputes within the court's jurisdictional limits.

Injunctive Relief: Nothing in this section prevents either party from seeking injunctive or other equitable relief in any court of competent jurisdiction to prevent the actual or threatened infringement of intellectual property rights.

13. Governing Law

These Terms shall be governed by and construed in accordance with the laws of the State of California, United States, without regard to its conflict of law provisions. To the extent that arbitration does not apply, you consent to the exclusive jurisdiction and venue of the state and federal courts located in San Francisco County, California.

14. General Provisions

  • Entire Agreement: These Terms, together with our Privacy Policy, constitute the entire agreement between you and FBA Prep Checker regarding the Service.
  • Severability: If any provision of these Terms is held to be invalid or unenforceable, the remaining provisions shall remain in full force and effect.
  • Waiver: Our failure to enforce any right or provision of these Terms shall not constitute a waiver of that right or provision.
  • Assignment: You may not assign or transfer these Terms or your rights hereunder without our prior written consent. We may freely assign these Terms without restriction.
  • Force Majeure: We shall not be liable for any failure or delay in performance due to circumstances beyond our reasonable control, including but not limited to acts of God, natural disasters, war, terrorism, pandemics, government actions, internet or power outages, or third-party service failures.

15. Changes to These Terms

We reserve the right to modify these Terms at any time. When we make material changes, we will update the "Effective date" at the top of this page and notify you by email or by posting a prominent notice on the Service at least 14 days before the changes take effect. Your continued use of the Service after the effective date of revised Terms constitutes your acceptance of the changes.
