Welcome to RareSats. These Terms of Service (the “Terms”) form a binding agreement between you (“you,” “User”) and Fumiha Co., Ltd., operator of RareSats (“RareSats,” “we,” “us,” or “our”), governing your access to and use of the RareSats iPhone and Apple Watch app and the RareSats website (collectively, the “Service”). Please read these Terms carefully before using the Service.
READ CAREFULLY. RareSats is a display and showcase application for rare satoshis. It is not a wallet, custodian, broker, exchange, money transmitter, or financial institution. The Service uses only public on-chain data that you choose to add. By using the Service, you accept that public on-chain data is permanent and outside our control.
By downloading, installing, accessing, or using the Service, you agree to these Terms and to our Privacy Policy. If you do not agree, do not download, install, or use the Service.
You must be at least 13 years old (or 16 in the EEA/UK) to use the Service. If you are under the age of legal majority in your jurisdiction, you must have the consent of a parent or legal guardian.
You may not use the Service if you are subject to comprehensive economic sanctions imposed by Japan, the United States, the European Union, the United Kingdom, or the United Nations, or if your use is prohibited by applicable law.
RareSats is a display and showcase application for rare satoshis on Apple devices. The Service includes:
The Service is not:
The Service does not provide custody of any digital assets, and any buying, selling, transferring, or signing happens entirely outside the Service in tools you choose and operate yourself.
An account is optional. If you create one (including via Sign in with Apple), you are responsible for keeping your account credentials confidential and for all activity that occurs under it.
You are responsible for the security of the device(s) on which you install the Service, including the operating system, screen lock, biometric configuration, and any backup or sync features provided by the device manufacturer.
You are responsible for the public Bitcoin addresses or sat numbers you choose to add to the Service. Please verify before adding — public addresses cannot be “deleted” from the blockchain even if removed from the app.
The Service is read-only with respect to the Bitcoin network: it queries public on-chain data based on the public addresses or sat numbers you provide, classifies and displays your rare sats, and renders watch faces and creative exports. It does not custody, transmit, or transact in any digital asset.
To move, send, or spend a sat, you must use the wallet that holds the corresponding address. That activity occurs entirely outside the Service.
The Service identifies and labels rare satoshis based on public on-chain data and publicly documented satribute classifications. Identification depends on third-party indexers and evolving Bitcoin standards (including Ordinals).
We do not guarantee that any classification, ranking, or rarity label is comprehensive, error-free, or future-proof. Standards evolve; classifications may change; some sats may be re-classified or removed as data sources improve.
Rarity labels and visual presentation in the Service are not a representation regarding price, market value, liquidity, or investment merit. They are descriptive metadata about public on-chain history.
You agree not to:
If you obtained the iOS or watchOS app via the Apple App Store, the following terms supplement and, where they conflict, supersede the rest of these Terms with respect to your use on Apple devices. You acknowledge and agree that:
Certain features of the Service may be offered as one-time purchases or auto-renewing subscriptions processed exclusively through Apple In-App Purchase. Pricing, billing, refunds, and subscription management are handled by Apple in accordance with the Apple Media Services Terms.
Auto-renewing subscriptions automatically renew for the same period unless cancelled at least 24 hours before the end of the current period. You can manage or cancel your subscription in your Apple ID account settings.
Refunds for App Store purchases are governed by Apple’s refund policy. Where Apple does not provide a refund and applicable consumer protection law requires us to do so, we will honor that obligation.
The Service — including its software, designs, brand, satribute classification system, logos, and creative templates — is owned by Fumiha Co., Ltd. or its licensors and is protected by copyright, trademark, and other intellectual property laws.
Subject to your compliance with these Terms, we grant you a limited, non-exclusive, non-transferable, revocable license to install and use the Service for your personal, non-commercial use.
Public Bitcoin and Ordinals data is open and freely available; this license does not restrict your independent use of public on-chain data.
The labels, notes, and personal organization you add (e.g., naming or tagging your sats) belong to you. By submitting feedback or support requests to us, you grant us a non-exclusive, royalty-free, worldwide license to use such content for the purpose of operating, improving, and supporting the Service.
The Service depends on third-party services such as Apple platforms, push notifications, Bitcoin and Ordinals indexers, and cloud infrastructure. These services are governed by their own terms and privacy policies. We are not responsible for the performance, availability, security, or content of third-party services.
Core display features of the Service are offered free of charge. Optional premium features may be offered as one-time or subscription purchases under Section 8. RareSats does not charge or intermediate any on-chain network fees, because the Service does not transact on your behalf.
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE” WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING WITHOUT LIMITATION WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, ACCURACY, OR UNINTERRUPTED OPERATION.
Nothing in the Service constitutes financial, investment, legal, tax, or accounting advice. Rarity labels and gallery presentations are descriptive — they are not recommendations to buy, sell, hold, or value any digital asset.
We do not warrant the accuracy, completeness, or timeliness of third-party blockchain indexers, Ordinals data, or sat-number assignments. Standards evolve; classifications may change.
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, FUMIHA CO., LTD. AND ITS AFFILIATES, OFFICERS, EMPLOYEES, AGENTS, AND LICENSORS SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, REVENUES, DATA, GOODWILL, OR OTHER INTANGIBLE LOSSES, ARISING OUT OF OR IN CONNECTION WITH YOUR USE OF, OR INABILITY TO USE, THE SERVICE.
OUR AGGREGATE LIABILITY FOR ANY CLAIM ARISING OUT OF OR RELATING TO THE SERVICE SHALL NOT EXCEED THE GREATER OF (A) THE AMOUNTS YOU PAID TO US FOR THE SERVICE IN THE TWELVE (12) MONTHS PRECEDING THE EVENT GIVING RISE TO THE CLAIM, OR (B) ONE HUNDRED U.S. DOLLARS (USD 100).
Some jurisdictions do not allow certain exclusions or limitations of liability; in such jurisdictions, our liability will be limited to the maximum extent permitted by law. Nothing in these Terms excludes or limits liability that cannot be excluded or limited under applicable law, including liability for fraud or willful misconduct.
You agree to defend, indemnify, and hold harmless Fumiha Co., Ltd. and its affiliates from and against any claims, damages, liabilities, costs, and expenses (including reasonable attorneys’ fees) arising out of or related to: (a) your use or misuse of the Service; (b) your violation of these Terms or applicable law; (c) the public Bitcoin addresses or sat numbers you add and any consequences of doing so.
You may stop using the Service at any time and uninstall the app. We may suspend or terminate your access at any time, with or without notice, including if we reasonably believe that you have violated these Terms or applicable law, or if continued provision of the Service would create a security, legal, or operational risk. Sections that by their nature should survive termination — including 9 (IP), 13 (Disclaimers), 14 (Limitation of Liability), 15 (Indemnification), 18 (Governing Law) — will survive.
We may modify these Terms from time to time to reflect changes in the Service, applicable law, or business operations. Material changes will be communicated through the website and/or in-app notices. Continued use of the Service after the effective date constitutes your acceptance of the revised Terms.
These Terms are governed by the laws of Japan, without regard to its conflict-of-laws principles.
Subject to mandatory consumer protection laws in your country of residence, the Tokyo District Court shall have exclusive jurisdiction as the court of first instance for any dispute arising out of or in connection with these Terms or the Service.
Before filing a formal claim, you agree to attempt to resolve the dispute informally by contacting cs@raresats.me. We will work in good faith to resolve the dispute within 60 days.
These Terms, together with the Privacy Policy and any in-product disclosures, constitute the entire agreement between you and us regarding the Service.
If any provision is held invalid or unenforceable, the remaining provisions will remain in full force and effect.
Our failure to enforce any provision is not a waiver of our right to enforce it later.
You may not assign or transfer these Terms without our prior written consent. We may assign these Terms in connection with a merger, acquisition, or sale of substantially all assets.
We are not liable for any failure or delay caused by events beyond our reasonable control, including natural disasters, internet failures, governmental actions, or large-scale Bitcoin network disruptions.
These Terms are provided in English. Translations are for convenience only; the English version prevails in the event of any inconsistency.
