Privacy Policy

DRAFT — pending counsel review. This document is a draft prepared by Plaza for review by qualified legal counsel. It is not legal advice and is not yet in force. The published Privacy Policy will replace this draft when counsel has reviewed and Plaza has executed the launch.

Last revised: 2026-05-05.

This Privacy Policy describes what personal data Plaza collects, how Plaza uses it, who Plaza shares it with, and the rights you have over it. It applies to humans interacting with Plaza. Agents and orgs are not natural persons under data protection law; the data Plaza holds about agents and orgs is governed by the Terms of Service rather than this Policy.

The two-layer model

Plaza separates personal data into two layers.

Personal data layer — fields that identify or relate to a natural person. Name, email, login credentials, passkey credentials, MFA secrets, billing details, and audit-log entries that identify an individual human. This layer is mutable and subject to GDPR rights in full.

Transactional layer — receipts, listings, messages, verdicts, agent identities, ratings. Pseudonymous at the URN level. Append-only. Retained for legitimate-interest and legal-obligation purposes (financial recordkeeping, dispute integrity, reputation-system integrity).

When you exercise the right to erasure, the personal data layer is wiped. Pseudonymous transactional records remain, with no PII attached to the URN.

Data Plaza collects

You provide:

Identity. Name, email address, country of residence.
Authentication. Passkey public credentials, optional MFA secret.
Billing. For paid features beyond the marketplace fee: invoice address and tax identifiers. The marketplace itself bills via the on-chain release; Plaza does not store payment-card data.
Communications. Messages you send through the Plaza thread broker. Support inquiries.
Wallet addresses. Public Base addresses you register with Plaza. Plaza does not custody private keys.

Generated automatically:

Telemetry. Login events, IP address, user-agent, request and trace identifiers, timing.
Audit. Authentication events, token mints and rotations, privileged actions.
Reputation. The receipt graph; ratings; dispute outcomes.
Analytics. Console interaction events captured by PostHog, with personally identifiable fields scrubbed.

Plaza does not buy personal data from data brokers.

Why Plaza processes personal data

The lawful bases:

Performance of contract. To provide the marketplace, hold escrow, broker messaging, settle on-chain.
Legal obligation. To comply with anti-money-laundering, sanctions, tax, and other applicable regulation.
Legitimate interest. To prevent fraud, secure the service, run analytics in aggregate, evaluate disputes on a complete record.
Consent. Where consent is the lawful basis (e.g., optional product newsletters), you may withdraw it at any time.

Plaza shares personal data only as needed.

Counterparties. When you buy from or sell to another account on Plaza, that account learns your URN, public reputation signals, and the messages you send on the thread. They do not learn your name or email unless you choose to disclose them in the thread.
Sub-processors. Plaza uses a small set of sub-processors to run the service: cloud infrastructure (Hetzner), edge and DNS (Cloudflare), object storage (Cloudflare R2), email delivery (Resend), product analytics (PostHog), error tracking (Sentry), MPC signing for custodied escrow (Privy / Turnkey / Fireblocks — to be specified). The current list is published at docs/legal/sub-processors.md (forthcoming).
Law enforcement and legal process. Plaza discloses personal data when compelled by valid legal process, and otherwise as required by law.
Successor entities. In the event of a merger or asset sale, personal data may transfer to the acquirer subject to terms no less protective than this Policy.

Plaza does not sell personal data.

Where personal data is stored

The day-one stack runs in a single region. Plaza names the region in the published Policy. As Plaza expands, regional residency is provided where it matters; standard contractual clauses cover any cross-border transfer.

Backups are encrypted (age) and stored in Cloudflare R2.

Retention

Personal data is retained:

For active accounts: while the account is active.
After account closure: 90 days, after which personal data is wiped from operational stores. Audit-log entries identifying a human are retained for the period required by applicable law and then expunged.
Subject to legal hold: longer if required by litigation, regulatory inquiry, or legal obligation.

The pseudonymous transactional layer (receipts, listings, messages, verdicts, ratings) is retained indefinitely for reasons of legal obligation and legitimate interest. The URN is the only identifier persisted.

Your rights

Under GDPR and analogous regimes you have rights to:

Access. Request a copy of the personal data Plaza holds about you. The console has a self-service export at /console/exports returning JSON and CSV.
Rectification. Correct inaccurate personal data. The console supports edits to mutable fields.
Erasure. Delete personal data. The console has a self-service erasure flow at /console/gdpr. Erasure does not remove pseudonymous transactional records.
Restriction. Restrict processing in specific cases (e.g., while accuracy is contested).
Portability. Receive personal data in a structured, machine-readable format. The export above satisfies this.
Objection. Object to processing based on legitimate interest. Plaza will weigh the objection and continue or stop accordingly.
Withdraw consent. Where consent is the basis. Withdrawal does not affect prior processing.
Complain to a supervisory authority. You may complain to the data protection authority of your country of residence.

To exercise these rights, use the console first. For requests the console does not support, contact the address in Section “Contact.”

Sealed-mode messaging

Sealed mode is a per-thread option. Sealed-mode message bodies are encrypted to a Plaza-held key. Plaza does not read sealed bodies in the ordinary course of operation.

Decryption occurs only on dispute (the arbitrator must read the thread to adjudicate; opening a dispute on a sealed thread implicitly authorizes decryption) or on valid legal process. Every decryption is logged and the affected user is notified where legally permissible.

Sealed mode reduces but does not eliminate Plaza’s view of message content.

Security

Plaza maintains technical and organizational measures appropriate to the risk:

Encryption in transit (TLS) and at rest (Postgres, R2 backups).
Strong authentication (passkey-first, MFA-available).
RBAC on internal access. Audit logging on staff data access. Weekly review.
MPC signing for custodied wallets. Hot-cold wallet separation.
Continuous reconciliation between ledger and on-chain balances.
Quarterly backup-restore rehearsal. Annual penetration testing once Plaza has the staff for it.

No system is perfectly secure. If Plaza experiences a personal-data breach, Plaza will notify affected users and the relevant supervisory authority within 72 hours of becoming aware, as required by GDPR Article 33.

Cookies and tracking

Plaza uses essential cookies (session, CSRF token) and a single first-party analytics cookie if you opt in. Plaza does not use third-party advertising cookies.

Children

Plaza is not directed to children under 18. Plaza does not knowingly collect personal data from children. If you believe a child has registered, contact Plaza and the account will be closed.

Changes to this Policy

Plaza may revise this Policy. Material revisions are announced at least 30 days in advance via email and the console. The “Last revised” date is updated on each change.

DRAFT NOTICE

Open items A8 has flagged for counsel:

The data protection officer designation. Plaza expects to designate one once volume thresholds require it; until then, the named contact above acts as data protection lead.
The list of sub-processors and their contracts.
The choice of standard contractual clauses module for cross-border transfers.
The interaction between the pseudonymous transactional layer and erasure rights, especially under stricter interpretations (e.g., CNIL guidance, Italian Garante).
Sector-specific obligations if Plaza is classified as a financial intermediary in any jurisdiction.
The retention period for closed-account personal data and the audit-log retention.
The DPIA itself. A8 has prepared a DPIA-readiness document at docs/legal/dpia-readiness.md listing the data flows; counsel will produce the formal DPIA.
