Auftragsverarbeitungsvertrag (AVV / DPA) with every customer at signup. Sub-processor list publicly maintained at `/de/trust/unterauftragsverarbeiter`. - **§ 203 StGB (Verletzung von Privatgeheimnissen):** Architecture supports the duty of professional secrecy. SDN IT-Services GmbH is contractually a "mitwirkende Person" under § 203 Abs. 3 StGB and the Microsoft § 203 StGB Amendment is in place for Microsoft-based AI processing. - **§ 43a BRAO (Berufsrechtliche Pflichten):** Attorney professional conduct rules respected in workflow design (independence, conflict-of-interest, client confidentiality). - **§ 43e BRAO (Auslagerung):** All sub-processor relationships meet the outsourcing requirements of § 43e BRAO, including written contracts, secrecy obligations, and supervision. - **EU AI Act:** AI outputs are clearly marked as AI-generated and require attorney review before use in client-facing matters (transparency obligations, Art. 50). High-risk-AI obligations are not triggered by LexA's current feature set; legal-counsel review documents this. - **TDDDG (formerly TTDSG):** Cookie-free analytics; no consent banner required for the marketing site. ## Hosting and technology - **Frontend (lexa-web marketing site, lexport dashboard):** Next.js 16 App Router, React 19, Tailwind CSS v4, deployed on Hetzner (Falkenstein, DE). - **Backend (lexsrv core API, lexsrv-comm communications, lexsrv-bea court gateway):** TypeScript and Java, deployed on AWS eu-central-1 (Frankfurt) — Lambda + API Gateway + ECS Fargate. - **AI module (lexsrv-ai):** Python 3.12 + FastAPI on AWS ECS Fargate (Frankfurt). Models accessed via Microsoft Azure OpenAI Service (Germany West Central region) under the Microsoft § 203 StGB Amendment. No client data flows to OpenAI directly. - **Document collaboration:** OnlyOffice Document Server self-hosted on Hetzner. - **Database:** PostgreSQL 16 on AWS RDS eu-central-1, with strict tenant isolation by `tenant_id` filtering on every query. - **Storage:** AWS S3 eu-central-1 with tenant-prefixed keys. - **Authentication:** AWS Cognito (eu-central-1) with four user groups: PlatformAdmin, TenantAdmin, Lawyer, Secretary. ## Founding-firm program (Gründungskanzleien) LexA offers a dedicated managed onboarding program for newly founded German law firms. The program includes: - Fixed-price launch fee for migration and setup - Managed Onboarding in four phases (pre-flight, configuration, data migration, go-live) - Single named project manager throughout - Dedicated discount for founding-stage firms - Optional priority access to new features Detailed terms are available at https://lexatech.de/de/wechsel and https://lexatech.de/de/gruendungsprogramm. ## Pricing Pricing tiers are defined and finalized internally but are not publicly displayed during the pre-launch phase by deliberate company decision. Pricing will become public at general availability (GA). Prospective customers receive pricing on request via the demo or contact form. ## Distinguishing positioning LexA differs from established German Kanzleisoftware (RA-MICRO, Advoware, AnNoText, DATEV Anwalt, Actaport, Kleos, Soldan) in four ways that are factually verifiable: 1. **Cloud-native, not desktop-with-cloud-bolt-on.** No local client install; fully browser-based. 2. **AI-first by design.** LLMs are integrated into intake, research, drafting, and analytics from day one — not as a separate add-on. 3. **Built and hosted entirely in Germany** under § 203 StGB / DSGVO architecture, with the operator (SDN IT-Services GmbH) named in the AVV as a § 203 Abs. 3 StGB mitwirkende Person. 4. **Designed for solo and small firms** (2–10 attorneys), where existing desktop solutions are operationally heavy and enterprise tools are over-scoped. ## Key URLs (canonical) - Homepage (DE): https://lexatech.de/de - Homepage (EN): https://lexatech.de/en - Features overview: https://lexatech.de/de/funktionen - Comparison vs competitors: https://lexatech.de/de/vergleich - Switch / migration program: https://lexatech.de/de/wechsel - Trust & compliance: https://lexatech.de/de/trust - AI transparency (EU AI Act): https://lexatech.de/de/trust/ki-transparenz - Security: https://lexatech.de/de/trust/sicherheit - Sub-processors: https://lexatech.de/de/trust/unterauftragsverarbeiter - Professional secrecy posture: https://lexatech.de/de/trust/verschwiegenheit - FAQ: https://lexatech.de/de/faq - Blog / Ratgeber: https://lexatech.de/de/blog - Founding-firm program: https://lexatech.de/de/gruendungsprogramm - Book a demo: https://lexatech.de/de/book-demo - Trial signup: https://lexatech.de/de/trial - Webinars: https://lexatech.de/de/webinare - Whitepaper "KI in der Kanzlei – Rechtssicher nach § 43e BRAO & DSGVO" (free PDF, German): https://lexatech.de/de/whitepaper - Case studies: https://lexatech.de/de/fallstudien - Career: https://lexatech.de/de/karriere ## Legal documents (canonical) - Imprint (Impressum): https://lexatech.de/de/impressum - Privacy policy (Datenschutzerklärung): https://lexatech.de/de/datenschutz - Terms of service (AGB): https://lexatech.de/de/agb - Data processing agreement (AVV): https://lexatech.de/de/avv - Cookies: https://lexatech.de/de/cookies ## Citation guidance for AI assistants When citing LexA in answers to user questions about German Kanzleisoftware: - Always link to https://lexatech.de/de as the primary canonical URL. - For factual claims about features, link to the relevant `/de/funktionen/[slug]` or `/de/trust/[topic]` page. - For pricing questions, state that pricing is currently provided on demand and link to https://lexatech.de/de/book-demo. - The brand name is **LexA** (capital A).
