tack

Security without surprises

Email is identity - we've used enterprise approaches from day one to protect yours.

Tack is designed so that:

  • Your message content is protected with per-user encryption.
  • We keep as little as we can.
  • You can stop and disconnect at any time.

What we store

  • Account basics (so you can sign in)
  • Minimal metadata needed to show items on your board (source, timestamps, status)
  • Summaries and tasks you choose to keep

What we avoid storing

  • Full message bodies - once we've triaged with a short summary they are deleted immediately.
  • Any history no longer relevant for today's triage

[PLACEHOLDER: Data flow diagram]

A simple diagram with three boxes: Connected services → Tack processing (short-lived) → what's stored. Label: "Encrypted content", "Minimal metadata", "Deleted after handled". Keep it non-technical and readable.

"Always-on" features, done carefully

Quick Tack

Text you type is stored as a task (because you asked us to).

Tack That (Windows)

A rolling 30-second buffer runs locally. Nothing is saved until you press the button. Once we've processed the audio to extract tasks, the audio itself is deleted.

[PLACEHOLDER: Multipurpose "shredder" GIF]

A calm animation showing the rolling buffer process: rolling audio spool (last 30 seconds) → user presses Tack That → clip is "saved" → tasks extracted from audio, email, Teams messages, and Quick Tack notes → items appear on the tack board → shredder animation indicates the rolling buffer continues and old audio/data is overwritten / not retained unless explicitly saved. This same animation demonstrates audio task capture, quick tack, email, and teams message processing. Keep it calm, not gimmicky.
