Sub-processors

Last updated: June 5, 2026


Quillon uses the following sub-processors to provide the service. Quillon will give at least 30 days' notice before engaging a new sub-processor.

Sub-processor Purpose Region
Hetzner Application, database, and background-job hosting (compute, Postgres, Redis) United States (Ashburn, Virginia)
Cloudflare DNS, marketing site (Pages), edge, email routing, encrypted off-site database backups (R2) Global
Stripe Payment processing US / Global
Anthropic Large-language-model analysis of customer signal data US

Read-only integrations you connect

These are systems you already operate. Quillon reads from your own account using credentials you provide — you remain the controller of that relationship. They are listed here for transparency, not because Quillon sub-processes your data through them.

Integration What Quillon reads Region
Mixpanel Quillon reads per-user event counts and last-event time from your own Mixpanel project to compute churn-risk signals (read-only; no event content transferred) United States (or EU / India per your project residency setting)
Close Quillon reads contact, opportunity, and activity metadata from your own Close CRM account to enrich customer health (read-only; no write-back to Close, and no email or call content is read) United States

Any additional read-only integrations will appear in the table above as they ship — you remain the controller of any system you connect.
