DeadlineFlow — Notion Deadlines & Calendar

Every Notion deadline at a glance. One calendar across all your databases. Tick once — Notion stays in sync.

Every Notion deadline at a glance — across every database. DeadlineFlow is the deadline-and-calendar Chrome extension for Notion users who scatter due dates across half a dozen databases and end up missing the one that matters. Hit a hotkey, your calendar opens. Today, this week, this month — every deadline from every database, in one place, color-coded by source. Whether you track tasks in a To-Do database, content in a Content Calendar, projects in a Roadmap, deliveries in an Orders database, or all of the above — DeadlineFlow brings them together without you moving anything in Notion. ━━━━━━━━━━━━━━━━━━━━━━ HOW IT WORKS ━━━━━━━━━━━━━━━━━━━━━━ 1. Connect your Notion workspace once via OAuth. 2. Pick which databases to include. DeadlineFlow auto-detects each database's date property and "done" checkbox. 3. Press Ctrl+Shift+D (or Cmd+Shift+D on Mac). 4. The calendar opens with every deadline color-coded by database. Today's tasks, overdue tasks, and upcoming work are visible at a glance. 5. Tick a checkbox in DeadlineFlow — the matching page updates in Notion in real time. That's the whole workflow. No new database to maintain, no manual sync, no missed deadlines. ━━━━━━━━━━━━━━━━━━━━━━ WHY DEADLINEFLOW ━━━━━━━━━━━━━━━━━━━━━━ • One calendar across every Notion database — month view, today view, overdue view. • Color-coded by database — three databases means three colors, easy to see at a glance which world a deadline belongs to. • Two-way sync — check a task off in DeadlineFlow and Notion updates immediately. No copy-paste, no lag. • Auto-detected properties — DeadlineFlow finds your date column and your done checkbox without configuration. • Hide-done toggle per database — keep finished work out of view without changing your Notion setup. • Today triage — a focused view showing only what's due today and what's overdue. • Streak + stats — see how many tasks you completed this week vs. last week, your current streak of on-time deliveries, and your all-time count. • Light & dark mode + Auto (follows your system). • Hotkey: Ctrl+Shift+D (Cmd+Shift+D on Mac) opens DeadlineFlow instantly. Customizable in Chrome. ━━━━━━━━━━━━━━━━━━━━━━ WHO IT'S FOR ━━━━━━━━━━━━━━━━━━━━━━ • Project managers — every roadmap, sprint, and side project on one calendar. • Content creators — editorial calendar, social calendar, and content tasks unified. • Founders & operators — deliverables across product, marketing, and ops in one view. • Students — assignment due dates from multiple class databases at a glance. • Anyone using more than one Notion database for time-bound work — DeadlineFlow stops you from missing a deadline because it lived in the "wrong" database. ━━━━━━━━━━━━━━━━━━━━━━ 100% FREE — EVERYTHING INCLUDED • Connect unlimited databases. • Stats tab — weekly completed count, current and longest streak, all-time total. • No subscription, no license key, no catch. ━━━━━━━━━━━━━━━━━━━━━━ PRIVACY-FIRST DESIGN ━━━━━━━━━━━━━━━━━━━━━━ • Your tasks, deadlines, and database contents are read directly from your browser to Notion. They never touch our servers. • Your Notion access token is stored only in your browser's local storage — never on our servers. • Product analytics use an anonymous random UUID — we send event names (popup opened, view changed, etc.) and the extension version. Never deadline contents, database names, page titles, or Notion identifiers. • No browsing tracking, no ads, no data sales. DeadlineFlow only runs when you invoke it.

No duplication, no drift. vs. a notification bot — DeadlineFlow gives you the full picture in one view, not a stream of alerts. vs. building it yourself with linked databases — DeadlineFlow needs no Notion setup. It works with the databases you already have. ━━━━━━━━━━━━━━━━━━━━━━ SUPPORT ━━━━━━━━━━━━━━━━━━━━━━ Questions, feedback, bug reports: support@notionflow.io Uninstall feedback (sad to see you go): https://www.notionflow.io/deadlineflow/uninstall Built by NotionFlow — sibling extensions: DailyFlow (one-click daily Notion notes), Clipper (save anything from the web to Notion), Snapper (screenshot + AI → Notion).
