Platform Policies

Version: 1.1 · Effective: May 20, 2026 Binding for: All demand sources (DSPs), supply sources (Publishers), and platform partners

These policies govern technical and operational requirements for all participants. They supplement the Demand Source Terms of Service and Supply Source Terms of Service.

Blocked content categories

The following categories are strictly forbidden on the Praevis network:

Ad quality standards

All creatives served on the Praevis network must:

• Load within 1.5 seconds on a standard connection
• Not redirect through more than 3 domains before landing page
• Not auto-play audio without user interaction (web environments)
• Not expand beyond declared creative dimensions
• Not trigger downloads without explicit user action
• Use HTTPS for all assets

VAST-specific:

• Maximum wrapper depth: 3 levels
• Duration must match <Duration> tag declaration
• VPAID not accepted — use VAST 4.x with <Verification> nodes

Traffic quality standards

For demand sources:

• Minimum bid rate: 30% of received requests
• Sustained no-bid rate above 70% may result in QPS reduction
• Valid win rates: 5–40% of submitted bids
• Timeout rate must remain below 5% (circuit breaker threshold)

For supply sources:

• Real human traffic only
• No incentivised views without prior written approval
• Accurate content categories and genre metadata
• Valid domain/bundle identifiers — spoofing results in immediate termination

QPS limits

QPS increases require 48 hours notice. Excess traffic is throttled (HTTP 429).

Sanctions and geographic compliance

Nucleus AI Pte. Ltd. is incorporated in Singapore and complies with applicable sanctions regulations, including those administered by the Monetary Authority of Singapore (MAS), the United Nations Security Council, and — where relevant to our partners — the US Office of Foreign Assets Control (OFAC) and EU restrictive measures.

Our approach:

• Transparent geography: All bid requests include the end user’s country and region derived from IP address, as required by OpenRTB. We do not obscure, proxy, or alter user geography. DSPs are responsible for applying their own geographic compliance filters.
• Partner screening: We perform due diligence on all demand sources, supply sources, and platform partners prior to onboarding. We do not transact with entities on applicable sanctions lists.
• Monitoring: Traffic from regions subject to international sanctions is flagged and monitored. We reserve the right to suspend or block traffic from any geography or partner if we determine a compliance risk.
• No facilitation: We do not knowingly facilitate transactions that would violate applicable sanctions, including indirect transactions routed through intermediaries to circumvent restrictions.

Partner obligations:

• Partners must not route traffic through intermediaries to obscure its true geographic origin
• Partners must promptly disclose any changes to their ownership structure or beneficial ownership that could affect sanctions compliance
• Partners operating in jurisdictions subject to comprehensive sanctions must obtain prior written approval

Enforcement

Violations result in:

Appeals: Email [email protected] within 14 days of a suspension notice.

Policy updates: 30 days notice via email for material changes.
