The third parties that process personal data to run Starlight, where they are, and how we notify you of changes.
A sub-processor is a third party that processes personal data on Starlight's behalf to deliver the Service. This page is the authoritative list referenced by our Privacy Policy and incorporated as Annex 3 of our Data Processing Addendum. Every vendor here is bound by a written agreement with data-protection obligations at least as protective as the DPA, and none may use personal data to train AI models.
Info
Safeguard column: DPF means the vendor is certified under the EU-US Data Privacy Framework (and its UK and Swiss extensions); SCCs means we rely on the EU Standard Contractual Clauses with the UK Addendum; None required means the vendor receives no personal data from Europe in a form that constitutes a restricted transfer (for example, keyword queries or company domains only).

| Amazon Web Services, Inc. (Amazon Bedrock) | Hosts the primary outreach-writing model (Moonshot AI's Kimi K2.5) in AWS US regions.

| Meta Platforms, Inc. | Judging, planning, and chat agent reasoning (Muse Spark) | Prospect business context, drafts being evaluated, your instructions to the agent | United States | DPF |
| xAI Corp. | Research, web and X search, query parsing, signal and social scanning (Grok) | Prospect names and companies for research, search queries, public post text | United States | SCCs |
| Anthropic, PBC | Outage fallback for the writer and judges (Claude) | Same as the model it stands in for | United States | DPF |
| Google LLC | Grounded reply drafting with Google Search (Gemini); also the Gmail and Calendar APIs you connect | Reply threads being drafted, prospect context | United States | DPF |

| OpenStreetMap Foundation (Nominatim) | City boundary outlines for Local search, fetched server-side | Place names only | United Kingdom | None required |
- Amazon Web Services, Inc. (Amazon Bedrock): Bedrock does not store prompts or completions and does not use them to train models. The model weights are Moonshot AI's; Moonshot receives no data.
- HarvestAPI (Aventra Technologies Limited): Receives only the keyword phrases compiled from your listening skill, never names, emails, or account data, so no personal data is transferred to it.
These are your own providers. Starlight exchanges data with them only when you connect an account and only on your instruction, under your agreement with that provider. They are listed for completeness and are not sub-processors.
| Service | Purpose | Data exchanged |
|---|
| Gmail and Google Calendar | Send outreach, read replies to threads Starlight started, sync meetings | Outreach messages, reply threads, calendar events |
| Microsoft Outlook and Microsoft 365 Calendar | Send outreach, read replies to threads Starlight started, sync meetings | Outreach messages, reply threads, calendar events |
| HubSpot, Salesforce, Attio | Two-way contact sync with your CRM | Contact and company records you choose to import or export |
| LinkedIn, X, Reddit (via the Chrome extension) | Deliver approved messages and read your own messaging and search results in your browser | Nothing is sent to these platforms by Starlight's servers; see the Chrome Extension section of the Privacy Policy |
- Before a new sub-processor begins processing personal data, we update this page and email the owner of every workspace at least 15 days in advance
- You may object on reasonable data-protection grounds within that window by emailing legal@joinstarlight.com. If we cannot resolve the objection, you may terminate the affected Service as your remedy, as set out in Section 7 of the DPA
- Replacing a vendor with an equivalent one, or a vendor changing its own corporate name or hosting region, is announced the same way
| Date | Change |
|---|
| August 20, 2026 | First published as a standalone list. Added Amazon Web Services (Bedrock, which hosts the Kimi K2.5 writer model), Meta Platforms, OpenAI, Resend, Clearout, SerpApi, HarvestAPI, Reddit, Logo.dev, MapTiler, and OpenStreetMap Foundation, all of which were already in use but were missing from the table in the Privacy Policy. Writer-model calls were pinned to the Bedrock host the same day; before that the Gateway could route them to Moonshot AI's own API. |
