Terms of Service — Planet B 21

Important noticeThis is a legal agreement between you and Planet B 21, LLC. Planet B 21, LLC is the parent company of several product brands, including Cash to Hash (cashtoha.sh) and HashSentinel (hashsentinel.com). These Terms govern your use of planetb21.com and your general relationship with Planet B 21, LLC. Each of our brands operates under its own terms of service, which govern your access to and use of that brand's products and services; where brand-specific terms apply, they control over these Terms. These Terms contain a mandatory arbitration clause and class-action waiver (Section 12).

§ 01Introduction and the Parties

These Terms of Service (the "Terms") govern your access to and use of the website located at planetb21.com and your general interactions with Planet B 21, LLC, a Wyoming limited liability company (referred to in these Terms as "Planet B 21," "we," "our," or "us"). Planet B 21 is the parent company of several product brands, including cashtoha.sh (Cash to Hash, a consumer digital compute products brand) and hashsentinel.com (HashSentinel, a business-to-business security services brand). Each brand is a brand of Planet B 21, LLC and not a separate company.

Your use of any brand's products or services is governed by that brand's own terms of service (for example, the Cash to Hash Terms of Service at cashtoha.sh/terms and the HashSentinel terms at hashsentinel.com/terms). Where brand-specific terms exist, they control over these Terms with respect to that brand's products and services. These Terms apply only to the extent a matter is not addressed by the applicable brand-specific terms.

By accessing planetb21.com or otherwise using our services, you agree to be bound by these Terms. If you do not agree, you must not use our websites or services. In these Terms, "you" and "your" refer to the individual or entity that accepts these Terms.

You may only use our websites and services if all of the following are true:

You are at least 18 years of age (or the age of legal majority in your jurisdiction, whichever is higher).

You have the legal capacity to enter into a binding contract.

You are not a resident of, and are not accessing our services from, any jurisdiction subject to comprehensive sanctions administered by the U.S. Department of the Treasury's Office of Foreign Assets Control (OFAC), or any jurisdiction where our services are prohibited by local law.

You are not on any U.S. or international sanctions or debarment list.

You have not previously been suspended or removed from our services.

Brand-specific eligibility, verification, and screening requirements are described in the applicable brand-specific terms. We may refuse service to any person for any lawful reason.

§ 04Nature of Our Services

Planet B 21 provides digital products and professional services through its brands. We are not a bank, money transmitter, securities exchange, broker-dealer, investment adviser, or custodian. We do not take custody of customer funds or digital assets, and nothing on our websites constitutes investment, legal, accounting, or tax advice.

The specific nature of each product or service — including what you are purchasing, how it is delivered, and the risks involved — is defined in the applicable brand-specific terms, which you should read before making a purchase.

§ 05Payments and Taxes

Prices for our products and services are displayed at the point of sale and are quoted in U.S. dollars unless otherwise indicated. Payments are processed by third-party payment processors (for example, Stripe, Inc.) under their own terms and privacy policies.

Listed prices are exclusive of value-added tax (VAT), sales tax, and similar transaction taxes unless expressly stated otherwise. Where applicable law requires us to collect such taxes, the tax amount is calculated and displayed before you confirm payment. You remain responsible for any taxes applicable to your purchase that are not collected at the point of sale, except for taxes imposed on Planet B 21's net income.

§ 06Refunds and Service Credits

Refund, cancellation, and service-credit policies are defined per brand in the applicable brand-specific terms. Many of our products are perishable digital products for which all sales are final; the exact policy applicable to your purchase is the one stated in the terms of the brand you purchased from. Nothing in these Terms limits any non-waivable statutory consumer rights you may have under applicable law.

§ 07Acceptable Use

You agree that you will not, and will not permit any third party to:

Use our websites or services in violation of any applicable law, regulation, or sanctions program.

Use our websites or services for money laundering, terrorist financing, or to evade tax obligations.

Misrepresent your identity, provide false information, or use payment instruments you do not have authority to use.

Attempt to reverse-engineer, probe, disrupt, or interfere with our websites, services, or any associated systems.

Infringe the intellectual property rights of Planet B 21 or any third party.

All content, trademarks, logos, software, and materials available through our websites and services are owned by Planet B 21 or our licensors and are protected by intellectual property law. You may not copy, modify, distribute, or create derivative works of our materials except as expressly permitted by us in writing or by applicable law.

§ 10Disclaimers

OUR WEBSITES AND SERVICES ARE PROVIDED "AS IS" AND "AS AVAILABLE." TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, PLANET B 21 DISCLAIMS ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT.

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, PLANET B 21'S TOTAL AGGREGATE LIABILITY TO YOU ARISING OUT OF OR RELATING TO OUR SERVICES OR THESE TERMS, REGARDLESS OF THE FORM OF ACTION, WILL NOT EXCEED THE TOTAL AMOUNT YOU PAID TO PLANET B 21 FOR THE SPECIFIC PRODUCT OR SERVICE GIVING RISE TO THE CLAIM IN THE NINETY (90) DAYS PRECEDING THE EVENT. IN NO EVENT WILL PLANET B 21 BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR LOST PROFITS, LOST OPPORTUNITY, OR LOSS OF DATA OR DIGITAL ASSET VALUE.

§ 12Governing Law; Arbitration; Class-Action Waiver

These Terms are governed by the laws of the State of Wyoming, without regard to conflict of laws principles.

Any dispute, claim, or controversy arising out of or relating to these Terms or our services will be resolved by binding arbitration administered by the American Arbitration Association under its Commercial Arbitration Rules, with the seat of arbitration in Wyoming. Judgment on the award may be entered in any court of competent jurisdiction.

YOU AND PLANET B 21 AGREE THAT ANY ARBITRATION OR PROCEEDING WILL BE CONDUCTED ONLY ON AN INDIVIDUAL BASIS AND NOT IN A CLASS, CONSOLIDATED, OR REPRESENTATIVE ACTION. You waive any right to a jury trial and to participate in a class action.

Notwithstanding the above, either party may seek injunctive or equitable relief in a court of competent jurisdiction to protect intellectual property rights.

§ 13Indemnification

You agree to indemnify and hold harmless Planet B 21 and its officers, directors, employees, and agents from and against any claims, damages, losses, liabilities, and expenses (including reasonable attorneys' fees) arising out of or related to (a) your use of our websites or services, (b) your breach of these Terms, or (c) your violation of any law or the rights of a third party.

§ 14Modifications to the Terms

We may modify these Terms at any time by posting an updated version at planetb21.com/terms. Material changes will be communicated by notice on our website or by email where appropriate. Continued use of our websites or services after the effective date of the updated Terms constitutes acceptance.

§ 15Miscellaneous

These Terms, together with any brand-specific terms and policies referenced herein, constitute the entire agreement between you and Planet B 21 regarding the subject matter they cover and supersede all prior agreements on that subject matter. If any provision of these Terms is found to be unenforceable, the remaining provisions remain in full effect. Our failure to enforce any right is not a waiver of that right. You may not assign these Terms without our prior written consent; we may assign these Terms freely. These Terms do not create any agency, partnership, joint venture, or employment relationship between you and Planet B 21.
