Terms of Service

These Terms of Service (“Terms”) form a legally binding agreement between you and Aurea CV OÜ, a private limited company incorporated in Estonia with its registered office in Tallinn, operating the LearnCoin service at learncoin.meand via the LearnCoin API (“LearnCoin”, “we”, “us”).

By using the LearnCoin website, API, or any credential anchored through LearnCoin, you accept these Terms. If you do not agree, do not use the service.

LearnCoin is verifiable-credential infrastructure. We provide an API that lets issuing organisations (“Tenants”) create cryptographically signed credentials conforming to the W3C Verifiable Credentials 2.0, W3C Decentralized Identifiers, Open Badges 3.0, and Blockcerts v3 specifications. LearnCoin batches those credentials, computes a Merkle root, signs the batch with a hardware-backed key, anchors the Merkle root on the Base public blockchain, and publishes a public verification URL for each credential.

Three roles interact with the service: Tenants (who sign a commercial agreement with us and issue credentials to their communities), Recipients(individuals who hold a credential we have signed and anchored on a Tenant's behalf), and Verifiers (any third party checking that a credential is authentic).

The following commitments are part of this contract, not marketing language. We would rather walk away from a deal than dilute them.

3.1 Verification is free, forever, for anyone

Verifying a LearnCoin credential is free of charge. No account, subscription, quota, or rate-limit applies to human verifiers using the public verification page, and we do not impose per-verification fees on any party. Programmatic verification via standards-compliant tooling (the Blockcerts Verifier Web Component, cert-verifier-js, or native Blockcerts wallets) is likewise free and requires no account with us.

3.2 Credential permanence

Credentials we have signed and anchored are designed to remain verifiable indefinitely. The Merkle root written to the Base blockchain is immutable. The published verification URL is stable. We will not remove, invalidate, or silently break credentials because a Tenant's subscription has lapsed, because we have discontinued a feature, or because the commercial relationship with a Tenant has ended.

3.3 Escape hatch on shutdown

If LearnCoin ever winds down — acquisition, dissolution, strategic shutdown, insolvency — every credential issued remains verifiable without us. Because credentials are anchored on a public blockchain and follow Blockcerts v3 and W3C VC 2.0 specifications, any standards-compliant verifier can check them against the on-chain anchor without touching LearnCoin infrastructure. Before any wind-down becomes final, we will publish an export of all credential JSON-LD to public, censorship-resistant storage (IPFS, Arweave, or equivalent) and publish a wind-down notice at least 90 days in advance where legally permitted.

3.4 Open standards, not proprietary lock-in

Every credential we issue is parseable and verifiable by generic W3C Verifiable Credential tooling, Open Badges 3.0 importers, and Blockcerts-compatible wallets. We will not introduce proprietary formats or verification logic that break standards interoperability.

Tenants are responsible for the factual accuracy of every credential they issue and for the lawful basis under which they collect and transmit recipient data to LearnCoin. By issuing a credential through LearnCoin, the Tenant represents and warrants that:

• They are the rightful issuer of the stated achievement, or they have authorisation from the awarding body to issue on its behalf.
• The factual content of the credential (credentialSubject, achievement, evidence) is accurate and not misleading.
• They have obtained the recipient's informed consent or have another lawful basis under GDPR Article 6 for processing the recipient's personal data through our service.
• They will enter into a data-processing agreement with us that reflects the GDPR Article 28 obligations, under which the Tenant is the data controller and LearnCoin is the processor for recipient data.
• They will honour recipient rights requests (access, rectification, erasure, etc.) and will coordinate with LearnCoin to tombstone credentials when required.

Tenants can revoke a credential they have issued, but only for legitimate credential-level reasons drawn from a closed enumeration. Commercial or subscription-based revocation is explicitly forbidden.

• Permitted revocation reasons— the credential was issued in error, the recipient's achievement is found to be fraudulent, the underlying accreditation has lapsed, the credential was compromised, or equivalent credential-integrity grounds.
• Forbidden revocation reasons — the Tenant has cancelled their subscription, the recipient has a commercial or personal dispute with the Tenant, or any reason unrelated to the factual integrity of the credential itself.
• Un-revocation window — a Tenant can self-revert a revocation within 14 days if it was made in error. Beyond 14 days, un-revocation requires operator assistance and is available for up to 5 years from the original revocation, which is more generous than industry practice because real issuer errors are often discovered weeks or months later.

Revocation is a statement about the credential, not an erasure of personal data. Erasure is handled separately — see our Privacy Policy, section 5.

LearnCoin and the LearnCoin logo are trademarks of Aurea CV OÜ. The LearnCoin website, software, documentation, and API design are our intellectual property. Nothing in these Terms grants you any licence to these assets beyond what is necessary to use the service.

Each credential signed through LearnCoin carries the Tenant's identity and content. The credential content belongs to the Tenant; LearnCoin only provides the infrastructure to sign, anchor, and serve it.

Fees for LearnCoin are set out on the Pricing page and in the individual agreement signed with each Tenant. Verification is always free. Recipient accounts (for holding and sharing your own credentials) are free.

Subscription fees for Tenants cover issuance, signing, batching, on-chain anchoring, the public verification page, the API, support, and continued infrastructure operation. We may adjust fees with at least 30 days' notice to existing Tenants; adjustments do not apply retroactively to credentials already issued.

We aim for high availability of the LearnCoin API and verification endpoints but do not guarantee uninterrupted service. Scheduled maintenance will be announced in advance where possible. The Base blockchain itself is operated by a third party and is subject to its own availability and fee dynamics; temporary congestion or fee spikes can delay anchoring but do not invalidate credentials.

We recommend Tenants treat the LearnCoin API as an “eventually anchored” system — credentials are signed and served immediately, and the on-chain anchor settles shortly afterward.

The LearnCoin service must not be used to issue credentials that are fraudulent, misleading, defamatory, infringing, or unlawful. We may suspend or terminate Tenants who breach this clause. We cooperate with law-enforcement requests to the extent required by Estonian and EU law.

To the fullest extent permitted by law, LearnCoin's total liability for any claim arising out of or relating to the service is limited to the fees paid by the claimant to LearnCoin in the twelve months preceding the event giving rise to the claim. We are not liable for indirect, consequential, incidental, or punitive damages.

Nothing in these Terms excludes or limits liability that cannot be excluded under Estonian or EU consumer-protection law, including liability for fraud, wilful misconduct, or gross negligence.

Either party may terminate a Tenant agreement in accordance with the notice period set out in the individual contract. Following termination, existing credentials continue to be verifiable — this is the credential-permanence commitment in section 3.2. The Tenant will lose the ability to issue new credentials and to use the administrative API, but previously issued credentials remain live.

We may update these Terms as the service and the legal landscape evolve. Material changes will be communicated to Tenants at least 30 days in advance and posted on this page with an updated effective date. Continuing to use the service after a change constitutes acceptance of the updated Terms; if you do not agree with a change, you may terminate in accordance with section 11.

These Terms are governed by the laws of the Republic of Estonia, without reference to conflict-of-laws principles. Disputes that cannot be resolved informally are subject to the exclusive jurisdiction of the competent courts of Estonia. Consumers in the European Economic Area retain their right to invoke the mandatory consumer-protection law of their country of residence and to refer disputes to the European Commission's Online Dispute Resolution platform.
