Security & Trust

Your data security is fundamental to ChatSEO. This page provides a clear overview of how we protect your data and the measures we have in place.

At a Glance

Data Hosting & Infrastructure

• All primary infrastructure hosted on Hetzner Online GmbH in Germany (EU)
• Firecrawl (web scraping) self-hosted on EU infrastructure (Hetzner)
• Data encrypted at rest and in transit (TLS 1.3)
• Regular security assessments and vulnerability testing
• Role-based access controls with per-user authentication

Google Search Console: Zero-Storage Architecture

We designed ChatSEO with a zero-storage approach to your GSC data:

1. Read-only access: We request only the webmasters.readonly OAuth scope - we cannot modify your Search Console data
2. Real-time only: GSC data is fetched from Google's API, displayed to you, and immediately discarded
3. No database storage: Our database schema contains no tables or columns for GSC metrics (queries, impressions, clicks, rankings)
4. No caching: GSC data is not cached in Redis or any other data store
5. You control access: Revoke permissions anytime from your Google security settings

What we DO store: OAuth credentials (access token, refresh token) needed to authenticate API requests on your behalf. These are deleted when you disconnect your integration.

AI Usage: No Training, Ever

• Anthropic Claude (Sonnet 4, Haiku): Used for real-time SEO analysis and conversation
• Voyage AI: Used for vector embeddings in the cross-conversation memory system
• Under Anthropic's commercial API terms, data sent via their API is not used for model training
• We do not fine-tune, train, or improve any AI model using your data
• AI processing is ephemeral: your data is processed and the result returned, with no retention by the AI provider

Cookie Consent & Tracking

We implement strict GDPR-compliant cookie consent:

• Necessary only by default: Only Sentry (error monitoring) and Crisp (support chat) load without consent
• Strict opt-in: Analytics (Mixpanel, Customer.io) and marketing (Tolt, Meta Pixel) require explicit consent
• Granular control: Choose consent category by category
• Revocable anytime: Click the cookie icon or use the footer link to change your preferences
• Equal visual weight: Accept and reject buttons are presented with the same visual prominence
