Cake Day is built with a minimal data footprint. It collects only what’s needed to run celebrations, never sells data, and gives both individuals and admins clear paths to delete anything at any time.

​
What Cake Day collects

Workspace-level data
  • Workspace ID and workspace name
  • Bot tokens (encrypted at rest using application-level encryption — never stored in plaintext)
  • Settings: celebration channel, post time, timezone, and custom AI tone prompt (Pro only)
Member-level data
  • Slack user ID and display name
  • Birth month and day (never the year)
  • Work start date — year, month, and day (if provided)
  • Opt-in / opt-out status
Billing data
  • Stripe customer ID, subscription tier, and usage count
  • Stripe stores all card data directly — Cake Day never sees or stores card numbers
Activity logs
  • Records of which shoutouts were posted or skipped, used for usage tracking and audit purposes

​
What Cake Day does NOT collect

  • Your birth year
  • Email addresses
  • Message content or conversation history
  • Profile photos
  • Any data beyond what you explicitly provide

​
Data retention

Data typeRetention

Stripe billing recordsUp to 7 years (U.S. tax compliance)

​
AI and Google Gemini

Each shoutout is generated via a stateless call to the Google Gemini API — there is no persistent session and no shared context across workspaces. What Cake Day sends to Gemini per celebration:
  • The celebrant’s first-name handle (display name)
  • Celebration type: birthday or anniversary
  • Timing framing: today, tomorrow, or weekend-shifted
  • Year count (for anniversaries only)
Cake Day never sends Slack tokens, email addresses, message history, roster contents, or any organization-identifying details beyond the celebrant’s name. Training data: Per Google’s paid Gemini API terms, prompt and response content is not used to train or improve Google’s models. Cake Day uses the paid commercial Gemini API, not the consumer Gemini product. Pro custom tone prompts: Workspaces on Pro can set a custom AI tone prompt in Settings. This string is appended to Cake Day’s standard system prompt and is never shared across workspaces.

​
Deleting your data

As an individual member:
  • Run /cakeday me in Slack and select Remove me entirely to permanently delete your roster entry
  • Click No thanks on an invite DM to decline being added
As a workspace admin:
  • Go to the Roster page → three-dot menu next to a member → Remove
  • To delete all workspace data, uninstall Cake Day from Slack — all data is deleted within 30 days
Formal data requests (GDPR, CCPA, and similar): Email info@mswdigital.com with your workspace name and request. We acknowledge within 5 business days and complete deletion within 30 days, with written confirmation.
Stripe billing records (customer ID, subscription history, invoice metadata) are retained for up to 7 years regardless of uninstall, as required by U.S. tax law. This is noted in the Privacy Policy.
