Presence Scheduler for Slack

Keep your Slack dot 🟢 green—on your schedule—even when you’re away
from the keyboard, switching between workspaces, or letting the laptop sleep.

Why would I need this?

Slack flips you to Away after ~10 minutes of real inactivity (or immediately
when a tab loses focus). That can break collaboration workflows—stand-ups in
threads, on-call handoffs, queue assignments—when teammates don’t know you’re
actually around.

Presence Scheduler solves that by sending a tiny, harmless activity “pulse”
exactly when your working hours say you should look available, and staying
silent the rest of the time.

Headline features

• 🕑 Schedule-aware – set multiple windows per workspace, each in its own
  time-zone, Mon–Sun checkboxes, lunch gaps, or 24 × 7 “always-on”.
• 🖥️ Hidden tab, zero clutter – one background tab per Slack workspace, no
  pop-ups, no keyboard hijacking, <0.1 % CPU when idle.
• 🌍 Multi-workspace – pulses every team you’ve authorised, even across
  different Slack domains and grid instances.
• 🔒 Private – all schedule data lives in Chrome Storage; nothing leaves
  your browser except the synthetic mouse/keyboard events Slack already trusts.
• ⏸️ One-click pause – un-tick the Enabled box in the popup to let Slack
  idle naturally (great for PTO).
• 🔔 Server-side presence fallback (optional) – if you grant OAuth, our
  server keeps you green every 5 minutes even when Chrome is closed.

Quick start

1. Click Add to Chrome → Add extension.
2. Open the purple “PS” icon – pin it for next time.
3. Copy your Personal API token from the Presence Scheduler dashboard
   (sk_live_…) → paste → Save.
4. Hit Fetch schedules – you’ll see each workspace with a 🟢 dot.
5. Customise windows in the web app; click Fetch again to sync.

That’s it! The dot stays green whenever at least one rule is active.

How does it work?

• Every two minutes a hidden tab dispatches mousemove + keydown events
  inside Slack’s DOM—exactly the same events you’d generate by touching the
  mouse.
• No clipboard, file-system, or network permissions.
• Tab reuse: we open once, re-inject forever; if you close the tab we reopen
  next tick.
• When the browser sleeps we resume automatically on wake.

Permissions explained

Security & Privacy

• Source code is unobfuscated, audit anytime.
• No analytics, no trackers, no remote logging.
• API token is stored with Chrome’s built-in encryption (chrome.storage.sync).
• Pulses never leave your browser; our server only runs if you opt-in to the
  fallback feature.

Troubleshooting

• Dot still flips to Away
  → Check the popup: Enabled ✔? Token saved? Click Fetch schedules again.
• Infinite tabs?
  → Make sure Chrome “Tab Groups Collapse Freezing” isn’t force-closing the
  hidden tab; disable that flag if you’re on Canary.
• Status never shows green on mobile
  → Mobile Slack has its own idle logic; you need the desktop/web client open
  somewhere for presence to propagate.
