By accessing or using TrustAnchor ("the Service"), you agree to be bound by these Terms of Use. If you do not agree, do not use the Service.
TrustAnchor provides a document verification service that computes cryptographic hashes of uploaded files and records them on a public blockchain. The Service includes file hashing, blockchain anchoring, IPFS storage, and public verification lookup.
You are responsible for:
You agree not to use the Service to:
We reserve the right to immediately suspend or terminate accounts and remove content without notice if we determine, at our sole discretion, that a violation of these terms has occurred.
TrustAnchor does not proactively monitor or screen the contents of uploaded files. However, we comply with all applicable laws and will respond to valid legal requests and abuse reports.
DMCA and Takedown Requests: If you believe content hosted through our Service infringes your copyright or violates applicable law, you may submit a takedown request by contacting us with the following information:
Upon receiving a valid takedown request, we will remove or disable access to the content from our CDN and IPFS pinning services. Note that blockchain records (hashes and timestamps) are immutable and cannot be removed, but they do not contain file contents.
User Responsibility: You are solely responsible for the legality of the files you upload. By using the Service, you represent and warrant that you have all necessary rights to the content and that it does not violate any applicable law. You agree to indemnify and hold harmless TrustAnchor from any claims, damages, or expenses arising from content you upload or anchor through the Service.
You retain all rights to the files you upload. By using the Service, you grant us a limited license to process, store, and distribute your files as necessary to provide the verification service (hashing, IPFS pinning, CDN storage). Verification records on the blockchain are public and permanent.
You acknowledge that blockchain records are permanent and immutable. Once a verification is recorded on the blockchain, it cannot be modified, deleted, or reversed. This is a fundamental feature of the Service, not a limitation. Consider this before verifying any file.
The Service creates a blockchain wallet directly in your web browser for minting verification tokens. Your wallet is protected by a 12-word seed phrase (mnemonic phrase) — a sequence of words that acts as the master key to your wallet.
Important things to understand about your seed phrase:
Cryptocurrency transactions are irreversible. You are solely responsible for your wallet's security and any transactions made from it.
Paid plans are billed monthly. You may cancel at any time; your plan remains active until the end of the billing period. Refunds are handled on a case-by-case basis. Cryptocurrency payments are non-refundable due to the irreversible nature of blockchain transactions.
We strive to maintain high availability but do not guarantee uninterrupted service. We may modify, suspend, or discontinue any part of the Service at any time. Blockchain records remain accessible regardless of our service status, as they exist on a decentralized public network.
The Service is provided "as is" without warranties of any kind. TrustAnchor is not liable for any indirect, incidental, or consequential damages arising from your use of the Service. Our total liability is limited to the amount you paid for the Service in the 12 months preceding the claim.
TrustAnchor verifies that a file's hash matches a recorded blockchain entry. This proves the file existed in that exact form at the time of verification. It does not verify the accuracy, legality, or authenticity of the file's contents — only its integrity and timestamp.
We may update these Terms from time to time. Changes take effect when posted. Continued use of the Service after changes constitutes acceptance. We will make reasonable efforts to notify users of material changes.
