PRAXIS by TACITUS

Updated 2026-09-30

Sub-processors

Infrastructure and service providers that may process PRAXIS customer or workspace data.

PRAXIS is part of TACITUS, an independent experimental project operated by Giulio Catanzariti. No TACITUS legal entity has been incorporated. Institutional terms, data handling and contracting parties must be established before an evaluation. Nothing on this page excludes rights or liabilities that applicable law does not allow to be excluded.

Documented Infrastructure Baseline

Google Cloud provides core infrastructure, including Cloud Run, Firestore, Cloud SQL, Cloud Storage, Secret Manager, Cloud Tasks, Pub/Sub, Cloud Build, Artifact Registry, and Vertex AI.

Cloudflare provides DNS. GitHub hosts source code and workflow metadata. When subscriptions are enabled, Polar processes checkout, customer billing details and subscription management.

Model and Provider Configuration

Vertex AI is the default model runtime. Availability of other model paths depends on enabled configuration and provider access; actual execution may use an explicitly reported fallback.

Provider data-use and retention commitments depend on the service and agreement in force. This provider list does not itself establish a no-training, zero-retention or regulated-data commitment for a model.

Data Residency

The default production region is currently United States infrastructure, with PRAXIS operations centered on Google Cloud. EU residency options are tracked as a compliance roadmap item.

Specific enterprise residency or DPA requirements should be reviewed before onboarding regulated workloads.

Removed Providers

Dedicated structured-feed and scraper providers previously evaluated for PRAXIS are not part of the current launch processing stack unless a future product decision reintroduces them.
