Subprocessors

Last updated: 31 August 2026

This list is taken from the Othor Cloud application as it runs today — not from a vendor questionnaire. Legal entity names should match the signed contract (AWS, Stripe, OpenAI, Anthropic, Postmark). Processing regions below are where the product actually sends data.

To run Othor we use a small number of third parties. Every one that can process customer data is listed here, with what it does and where it runs.

We give at least 30 days’ notice before adding or replacing a subprocessor that processes customer data. Write to to be notified.security@othor.ai.

Applies to Othor Cloud. See the deployment table for Cloud + your keys and self-hosted.

Subprocessors that may process customer data

SubprocessorEntity (verify on contract)PurposeData it can accessProcessing region
Amazon Web ServicesAmazon Web Services, Inc. / AWS EMEA (as on your invoice)Hosting (ECS, ALB), PostgreSQL, Redis/ElastiCache, S3 (uploads, images, Drive extracts), CloudFront, SQS (SFTP intake), SES (website contact/bug/feature forms), CloudWatch logs and backupsConnection credentials (encrypted), column names and definitions, extracted file tables while a Drive/SFTP/document connection is active, analysis results, account data, form submissionseu-north-1 (Stockholm). CloudFront edge locations may serve the app globally. Another AWS region only if we have agreed it for that customer.
OpenAIOpenAI, L.L.C. (US)Default LLM for analysis, discovery, chat, and document intelligence (via LiteLLM in-process — not a separate vendor)Prompts and data submitted for analysis, generated outputsUS (default Cloud path)
AnthropicAnthropic PBC (US)Optional LLM when a workspace assigns a Claude model, or as a platform fallbackSame as OpenAI, for those requestsUS (default Cloud path)
Postmark (ActiveCampaign)ActiveCampaign, LLC (US)Transactional product email: verify, invite, password reset, narrative/digest alertsRecipient name and email; and any analysis content in the message bodyUS unless the Postmark server is set to their EU data centre
Amazon SES(part of AWS)Website contact, bug, and feature-request forms to the Othor teamName, email, subject, message, optional company / page URLeu-north-1
StripeStripe, Inc. / Stripe Payments Europe / Stripe India (as on your dashboard)Payment and subscription billingBilling name, email, address, transaction records. Card details are entered on Stripe and never stored by Othor.US / EU / IN as determined by the Stripe account
MixpanelMixpanel, Inc. (US)In-product analyticsUsage events, page URL, user agent; email, workspace id and name, role, plan typeEU ingest (api-eu.mixpanel.com in the app). Confirm the Mixpanel project residency is also EU.
Mailchimp (Intuit)The Rocket Science Group LLCAccount/marketing list at signup and verificationEmail address, subscription status, tags (e.g. New User, Verified)US (Mailchimp datacenter on the configured server prefix)
GoogleGoogle LLC / Google Ireland LimitedSign-in with Google; optional Google Drive and Calendar connectionsSign-in: name, email, Google account id. Drive: files the user authorises Othor to read (extracted into our AWS database). Calendar: events if that OAuth path is used.Global
SlackSlack Technologies, LLC (Salesforce), USOptional customer notifications (OAuth to the customer’s workspace); also internal alerts for website formsCustomer Slack: channel id and any analysis content in the message. Internal: name, email, and message text from contact/bug/feature forms.US

Optional / path-specific

These run only when that product path is on.

SubprocessorPurposeData it can accessProcessing region
TavilyExternal news lookup used by narrative/contextSearch query text (may be derived from the question or metric names)US
SugraExternal market/series dataProvider symbol and date range — not source tablesAs operated by Sugra
TerminalfeedExternal news/series dataSame pattern as SugraAs operated by Terminalfeed

Public statistical APIs we call without sending customer records (World Bank, BIS, Open-Meteo, open.er-api for FX) are not listed as subprocessors. They receive a series id or currency code, not your tables.

What we checked and do not list

Taken from the running services (auth, narrative, metrics, chatbot, organizations, metric-discovery, frontend):

  • No Sentry, Datadog, or similar APM. Application logs stay in AWS CloudWatch.
  • No Vercel / Netlify for the product app. app.othor.ai is served from AWS (ALB / CloudFront).
  • No separate vector database. Document intelligence uses OpenAI and tables in our Postgres.
  • LiteLLM is a library, not a vendor. Tokens go to OpenAI or Anthropic (or your keys).
  • Customer warehouses (Snowflake, BigQuery, Postgres, …) are the customer’s systems. We connect with credentials they provide; those vendors are not our subprocessors.
  • Engineering: Cursor is used on the Othor codebase. It is not given production database credentials by the product. It is not a customer-data subprocessor unless an engineer pastes production data into it — that is forbidden by internal rule.

Internal systems that may hold personal data

These are not in the analysis path. Support and sales correspondence can still reach them.

SystemEntityWhat reaches it
Slack (internal)Slack Technologies, LLCWebsite form submissions (name, email, message) and internal discussion of support issues
NotionNotion Labs, Inc., USInternal documentation and account notes (not wired in the product; used by the team)

Staff are instructed not to paste customer source data, credentials, or analysis output into Slack or Notion. That instruction is a written internal rule.

Website only

The marketing site and app shell load fonts from Adobe Fonts (Typekit). Adobe may see the visitor’s IP address. It does not receive analysis data or account credentials.
