Telemetry & Privacy

+

+ Taskdeck can collect anonymous usage data to help improve the product. + No personal information, card content, board names, or user-generated text is ever collected. + Telemetry is off by default and requires your explicit opt-in. +

+
+ + +
+

+ Telemetry is enabled. Anonymous usage events will be sent periodically. +

+

+ Telemetry is disabled. No usage data is collected or sent. +

+
+ What data is collected? +
    +
  • Page navigation events (which pages are visited, not content)
    • +
  • Feature usage counts (captures, proposals, board loads)
    • +
  • Error codes (no error messages or stack traces)
    • +
  • Workspace mode and app version

  • Anonymous session ID (rotated on each app restart)
