Slack Integration Privacy Disclosure
Last updated: May 22, 2026
This addendum supplements the Terse Privacy Policy and applies whenever Terse accesses information from Slack. In the event of any conflict between this addendum and the main Privacy Policy with respect to Slack user data, this addendum controls.
What Data We Collect from Slack
When you install Terse to a Slack workspace, we receive:
- Message content from channels you explicitly select for indexing. We never collect data from channels you have not selected.
- User identifiers: Slack user IDs, display names, and email addresses (when available to the app).
- Channel metadata: channel IDs and channel names.
- File references used by your configured workflows.
- Reactions on messages that your workflows respond to.
How We Use Slack Data
Slack data is used solely to execute workflows you configure in Terse. It is not used to train large language models, ours or anyone else’s. Selected message content is passed to LLM providers (see “Third-Party Sub-Processors” below) to generate workflow responses; those providers are configured to not retain or train on this data.
We do not analyze Slack content for marketing, advertising, or product analytics. We do not transfer Slack user data to any sub-processor not listed below.
No Model Training on Slack Data
We do not train, fine-tune, or otherwise contribute to model training using your Slack data. We have configured our LLM providers to honor zero-retention or zero-training settings on all traffic sent from Terse.
Third-Party Sub-Processors That May Receive Slack Data
| Sub-processor | Purpose | Data sent | Training | Retention |
|---|---|---|---|---|
| Anthropic (privacy policy) | Large language model inference for user-configured workflows. | Message excerpts for workflow context. | No | Zero (per API contract). |
| OpenAI (privacy policy) | Embeddings and large language model inference for user-configured workflows. | Embeddings of selected channel messages. | No (Zero Data Retention enabled). | Zero. |
| Render | Cloud hosting and compute for Terse’s application services that process workflow runs. | Slack message content and derived embeddings transit through Render compute during workflow execution. | N/A | Until deletion as described below. |
| Google Cloud (GCP) | Object storage for files referenced by workflows (for example, attachments) and secret management for encrypted credentials such as Slack OAuth access and refresh tokens. | File attachments referenced by Slack workflows, and encrypted Slack OAuth tokens. No raw channel message content or embeddings are stored in GCP. | N/A | Until deletion as described below. |
PostHog, our product-analytics provider, receives only event metadata (for example, “workflow triggered”). PostHog does not receive Slack message content, channel content, user identifiers, or any other Slack user data.
Data Retention and Deletion
- Raw Slack message content is retained for 30 days in our database to power workflow context, after which it is deleted automatically.
- Access and refresh tokens are stored encrypted in Terse’s secret store and are retained until the workspace uninstalls Terse or you disconnect Slack.
- On uninstall, Terse revokes the Slack OAuth tokens and deletes all Slack data — including raw message content, embeddings, audit logs, and backups — within 30 business days, in line with our general cleanup policy.
Access, Export, and Deletion Requests
You can request access, export, or deletion of your data by emailing privacy@useterse.ai. We respond within 30 days.
Workspace administrators can delete all workspace data immediately by uninstalling Terse from Slack, which revokes our access tokens and triggers deletion of associated Slack data within 30 business days.
Revoking Terse’s Access to Your Slack Workspace
You may revoke Terse’s access to your Slack workspace at any time using either of the following methods:
- From within the Terse web app, navigate to Settings → Integrations → Slack and click Disconnect.
- From your Slack workspace, go to Settings & administration → Manage apps, select Terse, and click Remove app.
