Your To-Do App Forgets. TaskVault Remembers.

Google Tasks and Keep treat tasks as temporary scratchpads — no history, no exports, no reporting. TaskVault turns them into a permanent, searchable record.

⚠️ The Disappearing Task Problem

Tasks, reminders, and meetings scattered across Google apps quietly vanish the moment they're done or deleted:

No Revision History: Completed or deleted tasks disappear along with their notes and timestamps.
No CSV Export or Reporting: There's no native way to analyze what your team actually finished.
Scattered Sources: Tasks, Keep reminders, and Calendar events live in three separate silos.
No Project Overview: You can't see overdue counts, completion rates, or per-project progress at a glance.

✅ The TaskVault Solution

TaskVault snapshots every item into a Google Sheet you own, natively via Google Apps Script:

Permanent Vault: Removed items are kept as Archived — notes, tags, and timestamps are never lost.
One Unified Archive: Google Tasks, Keep-linked reminders, and Calendar events in a single clean table.
Executive Dashboard: Live KPIs, sparkline progress bars, and an interactive Focus View filter.
Hands-Free: A 15-minute background trigger keeps everything synced while you work.

🗄️

Zero Data Loss Recycle Bin

When a task or note is removed from Google Tasks or Keep, TaskVault marks it Archived instead of deleting it — notes, tags, and timestamps stay forever.

🏷️

Smart Tag & Assignee Parser

Automatically extracts #tags (e.g. #marketing, #sprint1) and @mentions (e.g. @alex) from titles and notes into filterable columns.

🔄

15-Minute Background Auto-Sync

A time-driven Apps Script trigger keeps your vault current hands-free. Enable or disable it with one click from the sidebar.

⚡

Differential Sync Engine

Compares every item against the vault and writes only what changed, with new items batch-appended for speed. Your custom edits stay safe.

📅

Calendar Events with Exact Times

Pulls primary calendar events from 14 days back to 90 days ahead, with precise start times, attendees as assignees, and past events auto-marked Completed.

🎯

Interactive Focus View

Switch between Overdue, Pending, Due in 48 Hours, Completed, or All with a single dropdown. Rows are color-coded red, amber, and green instantly.

💡 Google Keep™ Reminders, Archived Automatically

Google Keep reminders are natively linked into Google Tasks. When you set a reminder on a Keep note, Google adds it to your Tasks list with a direct link back to the note.

TaskVault detects these items, extracts the Keep URL into a clickable Open 🔗 link, parses any #hashtags and @mentions, and archives everything to your spreadsheet.

❌ Keep Alone: Reminders vanish once dismissed; no history, no reporting.
✅ TaskVault: Every Keep reminder becomes a permanent row with status and timestamps.
✅ One-Click Links: Jump straight back to the original Keep note from your sheet.
✅ Unified View: Keep, Tasks, and Calendar items side-by-side in one dashboard.

Read-Only, 100% Private Architecture

🔒 Zero External Data Transmission

All sync logic runs entirely inside Google Apps Script, bound to your own spreadsheet:

No External Servers: Task titles, notes, and events are never sent to Numbrate or any third party.
Your Sheet, Your Data: The archive lives in a Google Sheet you own and control.
Gumroad Verification Only: External network calls are limited to the Gumroad API for license validation.

🛡️ Minimal, Read-Only Permissions

Built according to Google Workspace Marketplace guidelines:

Read-Only Tasks & Calendar: TaskVault can never modify or delete your Google Tasks or events.
Current Spreadsheet Only: Writes only to the spreadsheet where it's installed.
Protected Reset: Wiping the vault requires a two-step confirmation and typing RESET.

Frequently Asked Questions

Everything you need to know about TaskVault for Google Sheets.

Can TaskVault modify or delete my Google Tasks? +

No. TaskVault requests read-only access to Google Tasks and Google Calendar. It only reads your items and writes copies into your spreadsheet — your original tasks, reminders, and events are never changed.

What happens when I complete or delete a task? +

Completed tasks are updated to Completed with a Completed At timestamp. If a pending task is deleted from Google Tasks or Keep, TaskVault keeps the row and marks it Archived, so its notes, tags, and history are never lost.

How do Google Keep reminders get into TaskVault? +

Google automatically links Keep reminders into Google Tasks. TaskVault reads those items, extracts the Keep URL as a clickable link, parses #hashtags and @mentions, and archives them alongside your regular tasks.

Which Calendar events are synced? +

TaskVault syncs events from your primary Google Calendar, from 14 days in the past to 90 days ahead. Timed events keep their exact start time, all-day events show the date only, attendees become assignees, and past events are automatically marked Completed. You can turn Calendar or Tasks sync off at any time in the sidebar.

How does the 3-day free trial work? +

The first time you open the TaskVault sidebar, a 3-day unrestricted trial starts automatically. A countdown badge shows the days remaining. After the trial, the dashboard, archive, and filters stay free to use — only new syncs require a license.

How do I activate my Gumroad license? +

After purchasing from Gumroad (numbrate.gumroad.com/l/taskvault), copy your license key from your receipt. In Google Sheets, open TaskVault → ⚙️ Open Sidebar, paste your key, and click 🔑 Activate License.
