Terms of Service

1. Agreement to Terms

By installing or using the Vonch Shopify app, you ("Merchant") agree to these Terms of Service on behalf of yourself and any entity you represent. These terms form a binding agreement between you and LYALIN CO. LTD ("Vonch", "we", "us").

2. Description of Service

Vonch provides cryptographically verified review attestations for e-commerce. When a buyer completes a purchase, Vonch facilitates a review flow that results in a tamper-proof, on-chain attestation linked to the verified transaction. Merchants display these attestations to establish trusted social proof.

3. Merchant Obligations

• You must only submit real, completed orders to the Vonch review flow. Fabricating or manipulating orders to generate false attestations is strictly prohibited.
• You must not abuse, reverse engineer, or attempt to circumvent the Vonch API or rate limits.
• You are responsible for ensuring your use of Vonch complies with applicable laws in your jurisdiction, including consumer protection and advertising regulations.
• You must not use Vonch to collect or process reviews for products or services you do not legitimately offer.

4. Data Processing and Buyer Privacy

By using Vonch, you acknowledge and agree that:

• Vonch processes buyer email addresses and order data sourced from your Shopify store solely to facilitate the verified review flow.
• You are responsible for ensuring your own privacy policy discloses this processing to your buyers where required by law.
• Vonch acts as a data processor on your behalf for this purpose, governed by our Privacy Policy.

5. Blockchain Immutability Notice

Once a review is attested on-chain, the attestation record is permanent and cannot be deleted from the blockchain. Only the buyer's pseudonymous wallet address and a cryptographic hash of the review are stored on-chain — no personally identifiable information is written to the ledger. In accordance with GDPR Recital 26, this pseudonymous data does not constitute personal data.

Off-chain personal data (email, name) stored in Vonch databases can be deleted on request per our data deletion policy.

6. Intellectual Property

All software, algorithms, and design elements of the Vonch platform remain the exclusive property of LYALIN CO. LTD. Nothing in these terms transfers any intellectual property rights to you.

7. Disclaimers

Vonch is provided "as is" and "as available." We make no warranty that the service will be uninterrupted, error-free, or free from security vulnerabilities. Blockchain networks are operated by independent third parties; we do not guarantee their availability or performance.

8. Limitation of Liability

To the fullest extent permitted by applicable law, LYALIN CO. LTD shall not be liable for any indirect, incidental, special, consequential, or punitive damages arising from your use of or inability to use Vonch, even if we have been advised of the possibility of such damages. Our total aggregate liability to you for any claim arising from these terms or your use of the service shall not exceed the greater of (a) the fees you paid to Vonch in the three months preceding the claim, or (b) one hundred US dollars (USD $100).

9. Termination

Either party may terminate this agreement at any time by uninstalling the app or ceasing use of the service. Upon termination, we will delete your personal data in accordance with our retention policy. On-chain attestations remain as they are immutable records of verified transactions.

10. Governing Law

These terms are governed by applicable law. Disputes shall be resolved through good-faith negotiation before pursuing formal legal proceedings.

11. Changes to Terms

We may revise these terms at any time. Material changes will be communicated via the Shopify admin panel or email. Continued use of Vonch after the effective date of revised terms constitutes acceptance.
