Reef is a product of Lobster Computer, Inc. ("we", "us", "Reef"). This guide
explains the shared Reef Slack app: what connecting it does, the access it
requests, how Slack data is handled, and how to remove it. It does not describe
separate per-agent Slack apps. Questions: privacy@lobstercomputer.com.
What connecting Slack does
Connecting Slack lets Reef work with messages and files you are allowed to see
so authorized people and agents can search, summarize, and keep up with work.
Reef can receive new-message events and perform limited history catch-up so the
connection stays current.
At your request, Reef may also post a Slack message using your personal
authorization. Separately installed per-agent Slack apps post as the agent and
may support additional message, file, or reaction actions within the permissions
shown when that app is installed. Reef does not independently expand your Slack
access or manage your workspace.
Two separate authorizations
Reef keeps workspace setup separate from each person's access:
- Your personal Slack authorization lets Reef read and search as you and
post a message as you when you request that action. Slack applies your own
channel membership and permissions, so Reef cannot use your authorization to
access a private channel or direct message you cannot access.
- The shared app's workspace installation lets Slack send supported events
to Reef and lets Reef deliver supported responses and link previews. A
workspace admin may need to approve this installation. The workspace app's
visibility never expands what Reef may show to an individual person.
People in the same Slack workspace do not inherit one another's Slack access.
Access the shared app requests
Slack displays the exact permissions requested before authorization. The shared
app requests permissions needed to read and search conversations available to
you, identify channels and members, post messages you request, receive supported
events and commands, show Reef link previews, and configure approved access to
private channels. Separate per-agent apps show and request their own permissions.
How to connect Slack
- Sign in to Reef and open Settings → Connections.
- Find Slack and choose Connect.
- Review Slack's authorization screen and approve the personal access.
- If Slack says workspace approval is required, follow your workspace's app
request process or ask a Slack admin to install the shared Reef app.
How to disconnect or remove Slack
- Disconnect your personal access in Reef. Open Settings → Connections,
find Slack, and choose Disconnect. Reef revokes its use of your stored
Slack authorization and stops accessing Slack through that connection.
- Remove the shared app from a workspace. A Slack workspace admin can open
Slack's Manage apps page, select Reef, and choose Remove App. Reef
does not provide a workspace-wide uninstall control inside Reef.
These are separate operations: disconnecting yourself does not uninstall the
app for coworkers, and removing the workspace app does not act as another
person's consent decision.
How Slack data is handled
- Data used. Reef processes message and file content, conversation metadata,
member information, credentials, and action results only to provide connected
Slack features.
- Credentials. Slack OAuth tokens are encrypted at rest and decrypted only
in memory when needed to provide the connection.
- Content. Slack content brought into Reef is encrypted at rest and may be
available to the people and agents authorized for the relevant collaborative
area. Your personal Slack authorization does not expand your permissions in
Slack. After content is copied or shared into Reef, access to that copy follows
Reef's permissions for the relevant collaborative area.
- Transport. Data moves over encrypted (TLS) connections.
- Use. Reef does not sell Slack data, use it for advertising, or use it to
train general-purpose models.
- Deletion. Disconnecting stops future access through that connection. To
request deletion of your Reef account and associated data, contact
privacy@lobstercomputer.com.
