1. What OrcaMail Is
OrcaMail is a wallet-to-wallet encrypted messaging service built on the Lightchain blockchain. It is operated by an individual developer and provided as-is for the benefit of the Lightchain community.
2. What Data We Collect
When you use OrcaMail, the following data is stored on our server:
- Wallet addresses — your Ethereum-compatible public address, used to route messages to your inbox. Wallet addresses are pseudonymous and are not linked to your real-world identity by this service.
- Encrypted message blobs — ciphertext of subject + body (ECIES). We cannot decrypt message content.
- Public keys — secp256k1 public key from opt-in (not a private key).
- Opt-in records — whether your wallet is registered to receive mail.
- Send counts — free-tier counters per wallet address.
- Auth signatures — short-lived signed messages used to prove wallet control for send/opt-in/opt-out (not stored long-term as identity documents).
We do not collect your legal name, phone number, or personal email. Hosting providers may process standard technical metadata (e.g. IP addresses in access logs) under their own terms — we do not use that for marketing or identity profiling.
3. End-to-End Encryption
Subject and body are encrypted on your device with ECIES before upload. The server stores ciphertext and cannot read content. Only the recipient can decrypt. From/to wallet addresses are visible for routing (they are not secret on a public chain ecosystem).
4. Where Data Is Stored
Data is stored on a third-party cloud infrastructure provider (currently Railway). It is not stored on any personal device belonging to the operator. The cloud provider may have its own data processing terms which apply to infrastructure-level operations.
5. Data Retention & Deletion
Messages remain stored until you delete them from your inbox. Opt-in and public key records remain until you opt out. Send count records are retained for service integrity. You can remove your data at any time by opting out in the Settings tab, which deletes your opt-in record and public key from our server.
6. No Sale or Sharing of Data
We do not sell, rent, or share your data with third parties for marketing or advertising purposes. Data may be disclosed if required by law.
7. No Warranty — Service Provided AS-IS
THIS SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, OR NON-INFRINGEMENT. THE OPERATOR DOES NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, ERROR-FREE, OR FREE FROM SECURITY VULNERABILITIES.
8. Limitation of Liability
TO THE FULLEST EXTENT PERMITTED BY LAW, THE OPERATOR SHALL NOT BE LIABLE FOR ANY DIRECT, INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES ARISING FROM YOUR USE OF OR INABILITY TO USE THIS SERVICE, INCLUDING BUT NOT LIMITED TO DATA LOSS, UNAUTHORIZED ACCESS TO DATA, SERVICE INTERRUPTION, OR ANY BREACH OF SECURITY. YOUR USE OF ORCAMAIL IS ENTIRELY AT YOUR OWN RISK.
9. Pseudonymity
OrcaMail does not require or collect real-world identity information. Wallet addresses are pseudonymous identifiers. We make no attempt to link wallet addresses to real identities. However, blockchain transactions are public by nature — on-chain activity related to the OrcaMail contract is visible on the Lightchain network.
10. Payments & No Refunds
Subscription payments are made in LCAI on the Lightchain blockchain. All on-chain transactions are final and irreversible. No refunds will be issued under any circumstances, including service interruptions, accidental payment, or permanent discontinuation of the service.
11. Service Availability
OrcaMail may be modified, suspended, or permanently discontinued at any time without notice. The service may go down temporarily or permanently. The operator is under no obligation to maintain or continue operating this tool.
