Overview

Our Commitment

EightX does not sell your personal data. We do not use your prompts or AI outputs to train our own models. We collect the minimum data needed to provide, improve, and secure the Platform.

This Privacy Policy applies to all users of the EightX Platform at eightx.app and api.eightx.app. The data controller is EightX LLC, a Cayman Islands exempted company.

If you are in the European Economic Area (EEA) or United Kingdom, EightX processes your personal data in accordance with the General Data Protection Regulation (GDPR) and UK GDPR respectively. If you are in California, EightX processes your data in accordance with the California Consumer Privacy Act (CCPA).

Data Sharing & Third Parties

5.1 Third-Party AI Providers

When you send queries through the Smart Router, your prompt content is transmitted to Third-Party Providers (e.g., OpenAI, Anthropic, Google, Mistral, Groq, Cohere, Perplexity) to generate responses. Each provider has its own privacy policy governing their use of your data. We recommend reviewing these policies if your prompts contain sensitive information.

5.2 Infrastructure Providers

  • Railway — Backend hosting (api.eightx.app). Our servers are located in Railway's cloud infrastructure. Railway's privacy policy governs data on their systems.
  • Vercel — Frontend hosting (eightx.app). Vercel processes request logs for CDN operation.
  • Supabase / PostgreSQL — Database hosting. Data is encrypted at rest.

5.3 Payment Processor

Stripe processes all payment card data. Stripe is PCI DSS compliant. EightX does not have access to your raw card data. Stripe's privacy policy governs payment processing.

5.4 Authentication

If you sign in with Google OAuth, Google processes your authentication. Google's privacy policy governs that interaction. EightX receives only your email, name, and profile picture from Google.

5.5 We Do Not Sell Your Data

EightX does not sell, rent, or trade your personal data to any third party for commercial purposes. Under the CCPA, EightX does not "sell" or "share" personal information as defined by California law.

5.6 Legal Disclosures

We may disclose your data if required to do so by law, court order, or regulatory authority, or if we believe disclosure is necessary to protect EightX's rights, prevent fraud, or protect the safety of our users.

06

Data Retention

Data Type Retention Period Reason
Account data Duration of account + 3 years post-closure Legal / disputes
Usage logs (metadata) 24 months Billing audit / analytics
Billing records 7 years Tax / financial compliance
Agent Passport records Duration of account Identity / security
IP address logs 30 days Security / rate limiting
Support communications 3 years from last communication Service quality
Marketing consent records 5 years from withdrawal GDPR compliance

After the retention period, data is securely deleted or anonymised. Anonymised, aggregated data (with no ability to identify individuals) may be retained indefinitely for platform analytics.

07

Security

EightX implements industry-standard security measures to protect your data:

  • Encryption in transit: All communication with eightx.app and api.eightx.app is via HTTPS/TLS. API keys and Agent Passport tokens are transmitted only over encrypted connections.
  • Encryption at rest: Database encryption at rest on our hosting infrastructure.
  • HMAC-SHA256 signing: Agent Passport tokens are cryptographically signed to prevent forgery.
  • Parameterized queries: All database operations use parameterized queries to prevent SQL injection.
  • Authentication: API access requires valid API key or Agent Passport. Invalid credentials return 401 responses. No unauthorised data is exposed.
  • Rate limiting: API endpoints are rate-limited to prevent abuse.
  • Credential storage: Passwords are hashed using bcrypt. API Keys are stored as cryptographic hashes, not in plaintext.
Security Incidents

If you discover a security vulnerability, please report it responsibly to security@eightx.app. We commit to acknowledging reports within 24 hours and resolving critical issues within 72 hours. Do not publicly disclose vulnerabilities before we have had an opportunity to address them.

In the event of a personal data breach that poses risk to your rights, EightX will notify affected users and relevant supervisory authorities within the timeframes required by applicable law (72 hours under GDPR).

08

Cookies & Local Storage

8.1 What We Use

EightX uses browser localStorage (not cookies) to store your authentication token on the client side. This token enables you to remain signed in across browser sessions without re-authenticating.

8.2 Session Storage

We may use sessionStorage for temporary state (e.g., current page state in the Dashboard) that does not persist after you close your browser tab.

8.3 Analytics

EightX may use privacy-respecting analytics tools. Where cookies are used for analytics, we will request your consent through a cookie banner before setting non-essential cookies.

8.4 Third-Party Cookies

Google Sign-In may set cookies in your browser as part of the OAuth authentication flow. These are governed by Google's cookie policy.

09

Autonomous Agents

When autonomous AI agents access the Platform using Agent Passports:

  • The agent's queries are logged under the account of the user who issued the Passport;
  • Agent Passport metadata (identifier, spend, quality score) is stored as set out in Section 2.6;
  • EightX does not receive or store the identity of the end-user interacting with an Agent unless that user has their own EightX account;
  • Operators deploying Agents that process personal data on behalf of end-users are responsible for ensuring their own GDPR/privacy compliance, including maintaining their own privacy notices and data processing agreements with end-users.
Enterprise Note

If your use case involves Agents processing personal data of your end-users at scale, please contact privacy@eightx.app to discuss a Data Processing Agreement (DPA).

10

International Data Transfers

EightX is based in the Cayman Islands. Our infrastructure providers (Railway, Vercel) may process data in the United States or other jurisdictions. Where we transfer personal data out of the EEA or UK, we ensure appropriate safeguards are in place, including:

  • Standard Contractual Clauses (SCCs): We rely on EU-approved SCCs for transfers to our US-based infrastructure and AI providers.
  • Adequacy decisions: Where applicable, we rely on adequacy decisions from the European Commission.

To request information about specific transfer mechanisms, contact legal@eightx.app.
