Sub-processors

Salon Guild CRM, part of the Opti Flo ecosystem

Last updated: 1 September 2026

Opti Flo Apps Ltd uses the following sub-processors to provide Salon Guild CRM. This list is referenced by our Privacy Policy and Terms of Service, and is kept up to date as our infrastructure changes. Where a sub-processor is based outside the UK, we rely on appropriate UK GDPR transfer safeguards, details of which are available on request to support@optiflo.app.

Supabase	Database hosting for CRM, booking, and client portal data	Salon and client records, bookings, invoices, authentication
Vercel	Application hosting for the website, portal, and platform apps	Application data in transit, hosting logs
Railway	Backend service hosting	Application data in transit, service logs
Stripe	Payment processing for subscriptions and, where used, salon client payments	Billing details, payment card data (Stripe does not share full card numbers with us)

Changes to this list

If we add, remove, or change a sub-processor in a way that materially affects how personal data is handled, we will update this page and, where required, notify salon owners in advance so they can raise any objection consistent with their own obligations to their clients.
