Data Residency

Where is your data stored and processed?

Lumo (Proton): Data hosted in Proton's own data centres in Germany and Norway. Zero-access encryption means even Proton cannot read conversation content. No US infrastructure dependency.

Logicc: Logicc states 100% hosting in Germany/the EU, with data at rest in Frankfurt on Microsoft Azure plus AWS EU and Google Cloud regions. EU residency is the explicit default for all customers, though the underlying infrastructure is provided by US-headquartered hyperscalers under SCC/DPA arrangements, so the 'exclusively German servers' claim carries some residual nuance.

Legal Jurisdiction

Which laws govern the company and your data?

Lumo (Proton): Swiss incorporation provides one of the strongest privacy jurisdictions globally. Outside US CLOUD Act reach. Swiss FADP and GDPR adequacy. Proton has a decade-long track record of defending user privacy.

Logicc: Incorporated as Logicc GmbH in Hamburg, Germany (Amtsgericht Hamburg, HRB 188043), an EU/EEA legal entity with no US parent. Data subprocessing relies on US hyperscalers governed by Art. 28 GDPR DPAs and SCCs.

Data Retention & Training

Is your data used for model training?

Lumo (Proton): Zero-access encryption on conversations. User data explicitly never used for model training. Open-source code enables independent verification of privacy claims.

Logicc: Logicc commits across all tiers that customer data is never used to train AI models, routing prompts through enterprise model deployments (Azure, AWS Bedrock, Google Cloud) that carry contractual no-training commitments, with Art. 28 GDPR DPAs in place. A §203 StGB confidentiality agreement is available on Secure+ and above; full configurable retention controls are not fully documented.

Certifications

ISO 27001, SOC 2, Cyber Essentials, etc.

Lumo (Proton): ISO 27001 and SOC 2 at Proton AG organisational level. Strong for a consumer-facing privacy product. ISO 27701 would further strengthen the posture.

Logicc: No formal third-party security certifications (e.g. ISO 27001 or SOC 2 Type II) are published on Logicc's site as of mid-2026. The platform relies on GDPR compliance, encryption and the certifications of its hyperscaler subprocessors rather than its own audited attestations; verify with the vendor.

Regulatory Fit

Suitability for regulated industries and professional services

Lumo (Proton): Excellent fit for privacy-sensitive professionals in legal and financial services. Swiss jurisdiction, zero-access encryption, and no training on user data address key regulatory concerns. Not EU-incorporated but GDPR adequate.

Logicc: Purpose-built for EU regulated industries — explicitly targeting law firms, medical practices, tax advisors, public agencies and banks under DORA — with §203 StGB professional-secrecy support and German data residency, making it well suited to GDPR/sectoral compliance needs despite the lack of independent certifications.
