Subprocessors
Last updated: 20 August 2026.
Voltex Computers Limited uses the companies below to operate voltexai.app. We are the controller. These parties process personal data on our instructions as processors (UK GDPR Article 28), except where we say they are not our subprocessors.
This list is the public register promised in our Privacy Policy. We will update it when we add or replace a processor. Questions: support@voltexai.app.
Processors we use
| Name | What they do | Where | Safeguard |
|---|---|---|---|
| 20i Limited | Cloud VPS hosting for the voltexai.app application, database, and backups | United Kingdom (primary). Vendor DPA allows onward transfers with UK IDTA / SCC addendum where needed | UK hosting; 20i GDPR Data Processing Agreement (addendum to hosting terms) |
| Resend, Inc. | Transactional email: sign-in OTP codes, export-ready notices, erasure confirmations, support notifications | United States | Resend DPA; EU–US Data Privacy Framework including UK Extension (confirm on the DPF list); SCCs in the DPA as fallback |
| Google LLC (Google Analytics 4) | Optional product analytics on the web app and marketing site, only after you accept analytics cookies | United States | Google measurement / ads data protection terms; EU–US Data Privacy Framework including UK Extension; SCCs as fallback. Consent Mode v2; no mail subjects or bodies sent as events |
| Anthropic, PBC | In-app help-centre assistant using Voltex’s API key: ticket and help-ask text only — not mailbox bodies. Also, when you switch on the VoltexAI Managed AI add-on (Standard/Pro) and run an AI action such as summarise or draft, the text of that request is sent to Anthropic under Voltex’s account. Mail sync and send still go only to your mail host | United States | Anthropic Commercial Terms incorporating their DPA, EU SCCs, and UK International Data Transfer Addendum |
Not our subprocessors
When you connect a mailbox, add your own AI key, or authorise Claude / ChatGPT / an API key, you are using your provider or app. They are not Voltex subprocessors. VoltexAI Managed AI is different: that add-on uses Anthropic as our processor for the AI actions you run.
| Name | What they do | Where | Safeguard |
|---|---|---|---|
| Your mail and calendar providers (Google, Microsoft, IMAP/SMTP, CalDAV, ICS) | Host your mailboxes and calendars. We sync a working copy using credentials you supply | Wherever that provider operates | Your contract with that provider — not a Voltex subprocessor |
| Your BYOK AI provider (for example OpenAI or Anthropic on your key) | Optional summarise, draft, triage, and related features when you add your own API key | Wherever that provider operates | Your contract with that provider. Inactive until you add a key |
| Connected apps you authorise (Claude MCP, ChatGPT Actions, API keys) | Act on mail/tasks with the scopes you grant | Depends on the app you connected | You authorise each app; you can revoke keys and consents in Settings |
