Terms of service

me.ochk.io is an identity you use to sign in across participating sites ("integrators"). When an integrator records a billable event for an action you authorize, a share of the fee flows back to you in sats. Your identity is anchored in Bitcoin, verifiable offline, and portable across the OrangeCheck family.

me.ochk.io is not a bank, exchange, broker, or wallet provider. It is an identity and reputation service with an attached cashback mechanism. OrangeCheck does not hold your funds — see section on custody below.

You may create an identity two ways: BIP-322 (you sign with your own Bitcoin wallet — full self-custody) or email-OTP (a one-time code; a federation-custodied wallet provisions in your browser). Both produce a stable, opaque did:oc identifier. No password is ever stored.

You are responsible for the security of the wallet, device, email account, or recovery mnemonic associated with your identity. Anyone with your keys or recovery factor can act as you. OrangeCheck cannot recover an account, reverse a sign-in, or restore a lost key or mnemonic.

• >>You must be at least 13 (or the age of digital consent in your jurisdiction)
• >>You must have the legal capacity to enter into a binding contract
• >>You must not be prohibited from using the Service under applicable law
• >>You must comply with all applicable laws and regulations

me.ochk.io is non-custodial with respect to OrangeCheck: OrangeCheck holds no private keys and no federation key shares, and cannot move your funds. BIP-322 users hold their own wallet. For email-OTP users, a Fedimint federation — run by independent guardian operators, never OrangeCheck — holds funds under a threshold scheme. You may graduate to full self-custody at any time.

me.ochk.io does not perform Know-Your-Customer checks and does not require your legal name, government ID, or physical address. Sybil resistance is achieved through protocol composition — BIP-322 sat-bond attestation, paid-action history, and integrator-defined gates — not identity verification. You must not use me.ochk.io to evade a KYC, AML, or sanctions obligation that applies to you elsewhere.

me.ochk.io publishes its abuse limits openly so legitimate users can see they are well below them. The canonical, current values are on the /security page. Activity that exceeds a review threshold may be held for human review; activity assessed as sybil farming, wash-trading, or collusion between an integrator and a user may have earnings withheld or reversed and the identity suspended.

• >>Do not operate multiple identities to multiply new-account bonuses
• >>Do not collude with an integrating site to manufacture billable events
• >>Do not script or automate actions to inflate earnings
• >>Do not misrepresent a real user action as authorized when it was not

prohibited — illegal

• >>Any unlawful purpose
• >>Violating any applicable laws or regulations
• >>Fraud, money laundering, or financial crimes
• >>Infringing intellectual property rights

prohibited — harmful

• >>Harass, threaten, or harm others
• >>Impersonate any person or entity
• >>Misrepresent your identity or affiliation
• >>Assert control of a Bitcoin address, identity, or handle you do not control

prohibited — technical abuse

• >>Interfere with or disrupt the Service or its servers
• >>Attempt unauthorized access to any account, system, or data
• >>Automated scraping or harvesting without permission
• >>Introduce viruses, malware, or malicious code
• >>Circumvent security features or rate limits

We reserve the right to investigate and act against anyone who violates these prohibitions — including terminating access and reporting to law enforcement.

Sites that integrate me.ochk.io receive a per-integrator scoped identifier for you, not your master identity — they cannot correlate you across sites unless you explicitly grant a scope. Integrators independently decide whether and how to trust your identity, including whether to admit, gate, or reject you. OrangeCheck is not a party to, and accepts no liability for, an integrator’s decisions or an integrator’s own terms, pricing, or conduct.

OrangeCheck's rights

The Service and its content (excluding user-generated content) are protected by copyright, trademark, patent, and other IP laws — including the OrangeCheck name, logos, branding, site design, software, code, algorithms, and documentation.

your license

You receive a limited, non-exclusive, non-transferable, revocable license to access and use the Service subject to these Terms. You may not sell, sublicense, or use the Service to build a competing product.

your content

You retain ownership of content you submit (feedback, support requests, integration material). You grant us a worldwide, non-exclusive, royalty-free license to operate and improve the Service using that content. You are responsible for your content.

open source

OrangeCheck protocol specifications and the @orangecheck/* packages are released under open-source licenses (MIT unless stated otherwise). Those portions are governed by their own license terms; these Terms govern the hosted service.

Nothing me.ochk.io provides is financial, investment, legal, or tax advice. me.ochk.io does not guarantee any level of earnings; cashback depends on integrator activity outside OrangeCheck’s control.

regulatory status

excluded damages

This exclusion covers, without limitation: direct, indirect, incidental, special, consequential, exemplary, punitive, reliance, and cover damages; and loss of Bitcoin, sats, cryptocurrency, tokens, assets, funds, private keys, seed phrases, passwords, data, profits, revenue, goodwill, reputation, business opportunity, anticipated savings, or use.

hard cap

If, notwithstanding the above, a court of competent jurisdiction finds OrangeCheck liable to you, our aggregate liability for all claims arising out of or related to the Service or these Terms is capped at the greater of (a) US$100 or (b) the total amount you actually paid OrangeCheck in the twelve (12) months immediately preceding the event giving rise to the claim.

essential purpose · jurisdictional floor

These limitations form an essential basis of the bargain and apply even if a limited remedy fails of its essential purpose. Some jurisdictions do not allow certain exclusions; there, the limitations apply to the maximum extent permitted by law and the remainder of these Terms stays in full force.

You agree to indemnify, defend, and hold harmless OrangeCheck and its affiliates from any claims, liabilities, damages, losses, costs, and expenses (including reasonable attorneys' fees) arising from:

• >>Your use or misuse of the Service
• >>Your violation of these Terms
• >>Your violation of any law or regulation
• >>Your violation of any third-party rights
• >>Content you submit or share
• >>Your negligence or willful misconduct

Your right: stop using me.ochk.io at any time; you may delete your identity from /me/settings. Our right: suspend or terminate access with or without cause, including for abuse or legal risk. Before deletion you should sweep any federation-custodied balance to self-custody (the graduate flow) — anchored events on Bitcoin and Nostr-published envelopes are immutable and cannot be deleted by OrangeCheck. The disclaimer, liability, indemnification, governing-law, and dispute provisions survive.

We may modify, suspend, or discontinue the Service at any time, with or without notice. We are not liable for any modification, suspension, or discontinuation.

exceptions to arbitration

• >>Small-claims court actions (if eligible and filed individually)
• >>Injunctive or equitable relief to protect intellectual property or confidential information
• >>Any claim that cannot lawfully be arbitrated under applicable law

one-year limit to bring claims

To the fullest extent permitted by law, any claim arising out of or relating to the Service or these Terms must be commenced within one (1) year after it accrues, or it is permanently barred.

opt-out of arbitration

You may opt out by sending written notice to hello@ochk.io within 30 days of first using the Service, including your name, the date you first used the Service, and a clear statement that you wish to opt out. Opting out does not affect the class-action or jury-trial waivers.

governing law

These Terms are governed by the laws of the State of Delaware, United States, without regard to conflict-of-law principles, and, where applicable, the U.S. Federal Arbitration Act (9 U.S.C. §§ 1–16). For users in the EEA, UK, or Switzerland, mandatory consumer-protection laws of your country of residence may apply and nothing here overrides those rights.
