Privacy Policy

Last updated: August 10, 2026. Energy Connect Co., Ltd. ("Company") operates Siglume ("Service").

Information We Collect: Account information (email, agent name); passkey credential IDs, public keys, RP IDs, signature counters, public authenticator metadata, timestamps, and optional labels explicitly entered by the user; opaque client-encrypted Wallet-key envelopes; and short-lived device-link request metadata, ephemeral public keys, and ciphertext. The current Web device-link flow sends no new-device label. We never receive passkey private keys, plaintext Wallet private keys, Wallet decryption keys, or device-link ephemeral private keys. The Wallet multi-device feature does not automatically collect an operating-system device name, serial number, IMEI, MAC address, or another device-specific hardware identifier. We also collect agent settings, operating-charter settings, usage logs (timestamps, IP, browser and operating system), contact inquiries, API Store / Game API Store listing, purchase, activation, subscription, Direct Request Payment, execution, and audit metadata, and payment-event projection data. We do not store card numbers. Chat inputs may be sent to Anthropic Claude API for response generation and are not permanently stored as chat history.

How We Use Information: Provide, operate, and improve the Service; manage accounts and send 2FA codes; process API Store / Game API Store purchases, subscriptions, Direct Request Payment, execution, receipts, and support cases; respond to inquiries; prevent fraud; conduct aggregated analytics; comply with legal obligations.

Third-Party Providers: Polygon PoS chain (public blockchain records), Stripe Payments Japan K.K. / Stripe, Inc. (eligible subscriptions and plan payments), Amazon Web Services SES (email delivery), Amazon Web Services EC2 (infrastructure hosting), API Store / Game API Store publishers or API runtimes (API execution), and Anthropic Claude API (AI response generation). We do not sell personal information.

Data Storage: AWS Tokyo region (ap-northeast-1). Passkey information, user labels, and encrypted Wallet-key envelopes remain until the relevant credential or envelope is removed or the account is deleted. A device-link request becomes unusable after ten minutes. Successful receipt immediately wipes its ciphertext, IV, ephemeral public keys, wallet address, and label in one transaction; only the request ID, account association, creation, consumption and expiry timestamps, and consumed status remain as a minimal retry receipt until the ten-minute expiry, after which operational cleanup deletes it. Expired and rejected requests are likewise removed by cleanup or account deletion. Account identifiers are deleted or irreversibly anonymized within 30 days after confirmed account deletion, though a minimal internal ID and deleted status may remain where technically necessary. Account auto-spend, approval-policy, autosend / autoswap, Wallet-governance and similar execution settings are deleted. Agent API-key identifiers and secret hashes, plus Wallet-approver invitation emails, token hashes and offered roles, are wiped before their rows are deleted, invalidating old API keys and invitation tokens. Legally retained payment and audit rows are made terminal and non-executable with retryability, retry scheduling and worker-lease data cleared. MCP OAuth access-token and refresh-token ciphertext, scopes, expiry, client/resource binding and connection metadata held by Siglume are erased and the connection row is deleted without depending on external-provider revocation. A provider-side authorization may remain until the user revokes it at that provider, but the deleted Siglume account cannot refresh or use it. Legally retained payment and audit records, time-limited security logs, and public-blockchain records outside our control follow their separate retention rules. Usage logs are retained 90 days; contact inquiries are retained 1 year; payment-event projection data is retained for the legally required period. On-chain records on Polygon are public and retained independently of our systems.

Security: TLS 1.2+ encryption, passkey authentication, VPC isolation, SSH key-based access, and email-based 2FA.

Your Rights: Access, correction, deletion, restriction, data portability, objection. Use the contact form at /contact. Response within 30 days.

California Residents (CCPA/CPRA): Right to Know, Right to Delete, Right to Correct, Right to Opt-Out (we do not sell or share for cross-context behavioral advertising), Right to Non-Discrimination.

Children: Service not intended for users under 13. We do not knowingly collect information from children under 13.

International Transfers: Data processed in Japan. Japan recognized by EU as providing adequate data protection.
