Sub-processors
These are the service providers Cimpli AI uses to run ReplyWell that handle personal data. Each is bound by data protection terms at least as protective as our Data Processing Agreement.
Providers that handle your customers' data
When your customers chat with your assistant, their messages and contact details pass through these providers:
| Provider | What they do | Data involved | Where |
|---|---|---|---|
| Supabase | Database, file storage and sign-in | Account details, uploaded documents, chats and contact details | Ireland (EU) |
| Vercel | Hosts the website and app | Everything passing through the app while it runs | App runs in Ireland (EU); Vercel is a US company |
| Anthropic | AI model that writes the replies | The customer's message, the recent conversation and the passages from the business's documents that relate to it | United States |
| Cloudflare (Turnstile) | Bot check when a chat starts, to stop spam | Chat visitors' IP address and browser signals (never the chat messages) | Worldwide; Cloudflare is a US company |
| Resend | Sends emails: handoff alerts and replies | Customer names, email addresses and messages in handoff emails; owners' email addresses | Ireland (EU); Resend is a US company |

Providers that run ReplyWell itself
These handle your account, billing and support emails, not your customers' chats:

|---|---|---|---|
| Stripe | Payments and subscriptions for business owners | Owners' billing details (never customers' chats) | UK, EU and United States |
| ImprovMX | Forwards emails sent to our support address | Emails you send us | France and United States |

Your own tools
If you connect Slack for handoff alerts, chat details are sent to your own Slack workspace. Slack is then a provider you've chosen, under your agreement with Slack, rather than one of ours.
Changes to this list
We'll email account holders at least 30 days before adding or replacing a provider that handles your customers' data, and update this page. If you object on reasonable data protection grounds, tell us at hello@replywell.io and we'll work with you on a solution; if we can't find one, you can cancel and we'll refund any unused prepaid period.
Transfers outside the UK
Where a provider handles data outside the UK, the transfer is covered by the UK International Data Transfer Addendum to the EU Standard Contractual Clauses, the UK International Data Transfer Agreement, or the UK–US “data bridge”, as appropriate.
