Privacy Policy
Last updated: 14 March 2026
1. Introduction
OPENGATE TECHNOLOGY LTD. ("Company", "we", "us", "our") is committed to protecting your privacy and the privacy of data processed through the Hippocortex platform. This Privacy Policy explains how we collect, use, store, share, and protect personal data when you use our platform, APIs, SDKs, and related services (the "Services").
We comply with the UK General Data Protection Regulation (UK GDPR), the EU General Data Protection Regulation (EU GDPR), the Data Protection Act 2018, and other applicable data protection laws.
2. Data Controller
The data controller for personal data processed through the Hippocortex platform is:
OPENGATE TECHNOLOGY LTD.
71-75 Shelton Street
Covent Garden, London, United Kingdom, WC2H 9JQ
Company Number: 17056279
Data Protection Contact: privacy@hippocortex.dev
When you use the Services to process personal data on behalf of your end users or through your AI agents, you act as the data controller and we act as a data processor. The terms of our data processing relationship are governed by our Data Processing Agreement.
3. Information We Collect
3.1 Account Information
When you register for an account, we collect your email address, display name, and hashed password. If you subscribe to a paid plan, we collect billing information through our payment processor (Stripe), including payment method details, billing address, and transaction history. We do not store raw credit card numbers on our systems.
3.2 Customer Data (Agent Events)
When you use the capture API, you submit agent interaction events that may contain personal data depending on your use case. These events include:
- •Message events (user and assistant conversation content)
- •Tool call events (tool names and input parameters)
- •Tool result events (tool execution output)
- •File edit, test run, command execution, browser action, and API result events
This data is processed through our capture pipeline (queued via Redis, persisted to PostgreSQL), optionally compiled into knowledge artifacts through the learn endpoint, and made available for retrieval through the synthesize endpoint. You control what data is submitted and are responsible for ensuring compliance with applicable data protection laws for any personal data included.
3.3 Usage and Telemetry Data
We automatically collect data about how you interact with the Services, including: API call volumes and endpoint usage, event counts by type, compilation frequency, synthesis request patterns, error rates, and response times. This data is aggregated and used to improve service quality, capacity planning, and abuse detection.
3.4 Technical Data
When you access the Services (including the website and dashboard), we collect: IP addresses, browser type and version, device information, operating system, referring URLs, and access timestamps. This data is collected through standard web server logs.
4. How We Process Agent Event Data
Agent event data submitted through the capture API follows this processing flow:
- 1.Ingestion: Events are received by the API, validated, and queued to Redis (BullMQ) for asynchronous processing.
- 2.Persistence: Background workers persist events to PostgreSQL with tenant-scoped isolation. Events are stored with their type, session ID, payload, and metadata.
- 3.Compilation: When you trigger the learn endpoint, a compilation worker analyses accumulated events and extracts patterns. Patterns are compiled into knowledge artifacts (task schemas, failure playbooks, causal patterns, decision policies).
- 4.Synthesis: The synthesize endpoint searches across memories and artifacts using semantic search (pgvector), assembles relevant context entries, and returns them within a token budget.
All processing occurs within your tenant's isolated scope. Cross-tenant data access is architecturally impossible due to tenant ID filtering at the database query level.
5. Legal Basis for Processing (GDPR)
We process personal data under the following legal bases:
- •Performance of contract (Article 6(1)(b)): Processing account information and Customer Data is necessary to provide the Services you have contracted for.
- •Legitimate interests (Article 6(1)(f)): Processing usage data for service improvement, security monitoring, and abuse prevention. Our legitimate interests do not override your fundamental rights and freedoms.
- •Consent (Article 6(1)(a)): Where we use non-essential cookies or process data for marketing purposes, we obtain your explicit consent. You may withdraw consent at any time.
- •Legal obligation (Article 6(1)(c)): Processing required to comply with tax, accounting, or regulatory obligations.
6. Data Retention
We retain data for the following periods:
Upon deletion, data is permanently removed from all active systems within 30 days and from all backup systems within 90 days.
7. Sub-processors
We use the following third-party service providers (sub-processors) to deliver the Services. Each sub-processor is bound by data processing agreements that provide protection consistent with this Privacy Policy.
We will notify you of changes to our sub-processor list at least 30 days before engaging a new sub-processor. You may object to a new sub-processor within 14 days of notification.
8. International Transfers
OPENGATE TECHNOLOGY LTD. is based in England. Some of our sub-processors operate in the United States. Where personal data is transferred outside the United Kingdom or the European Economic Area, we ensure appropriate safeguards are in place, including:
