byendofday.comPrivacy-First Calendar Analytics
byendofday.com analyzes your Google Calendar data completely in your browser - never on our servers. Get powerful productivity insights while your calendar data stays exactly where it belongs: on your device.
How byendofday.com Works
Your privacy is our priority. Here's how we keep your calendar data completely secure:
Connect Securely
You authorize byendofday.com through Google's official OAuth system. Think of it like giving someone a key to your house - but this key only opens one specific room (your calendar), and you can revoke it anytime.
Process Locally
Your calendar data is downloaded and processed entirely in your web browser. It's like using a calculator app - the numbers you enter stay on your device and are never sent anywhere else.
Analyze Privately
All analytics happen on your device using your browser's built-in storage. Your meeting details, schedules, and insights never leave your computer - just like editing a photo on your phone.
🔒 Your Calendar Data Never Leaves Your Browser
We use IndexedDB (your browser's secure local storage) to keep everything on your device. No cloud servers, no data transmission, no third parties.

Complete Privacy Transparency
Here's exactly what we can and cannot see with your calendar data:
❌ What We CANNOT See
- Your calendar events - Meeting titles, descriptions, locations
- Attendee information - Who you're meeting with
- Personal details - Private appointments, sensitive information
- Meeting content - What happens in your meetings
- Your schedule patterns - When you're busy or free
- Calendar data - Everything stays in your browser
Think of us like the company that made your calculator - we built the tool, but we can't see the numbers you type into it.
✅ What We CAN See
- That you logged in - Just like any website
- Which pages you visit - Basic website analytics
- Your account email - For authentication only
- Technical errors - To help us fix bugs
- Feature usage - Which tools you use (not your data)
We see only what any normal website sees - your interactions with our interface, not your private information.
Security & Compliance
We maintain the highest standards of security and privacy protection for your calendar data
Common Privacy Questions
We understand privacy is important. Here are answers to the most common questions:
🔍 Can you see my calendar events?
No. Your calendar data is processed entirely in your browser using IndexedDB local storage. It's like using a photo editing app on your phone - the photos stay on your device.
🌐 Does my data go to your servers?
No. We designed byendofday.com specifically to avoid this. All analytics happen locally in your browser. Think of it like a calculator - the numbers you enter never leave your device.
🔒 What if you get hacked?
Since we don't store your calendar data on our servers, there's nothing to steal. Hackers would find only account emails and usage statistics - no personal calendar information.
🔑 Can I revoke access anytime?
Absolutely. You can disconnect byendofday.com from your Google Account instantly through either your byendofday.com settings or Google's account permissions page.
👥 What about team features?
Even team analytics preserve privacy. Each person's calendar data stays in their own browser. We only combine anonymized patterns, never personal meeting details.
⚡ Why build it this way?
Privacy by design. We believe calendar data is deeply personal. By processing everything locally, we eliminate privacy risks that other analytics tools create.

For the Tech-Curious
Here's how we implement privacy-first calendar analytics:
🗄️ Local Storage Technology
IndexedDB: We use your browser's IndexedDB to store and process calendar data locally. This is a client-side database that never synchronizes with external servers.
Why IndexedDB? It's designed for complex data operations while keeping everything in your browser. Think of it as a private database that only your device can access.
🔌 Google API Integration
OAuth 2.0: We use Google's official OAuth flow with minimal scopes (calendar.readonly) to access only what's necessary.
Direct API Calls: Your browser communicates directly with Google's servers - we never act as a middleman intercepting your data.
⚡ Client-Side Processing
JavaScript Analytics: All calculations happen in your browser using JavaScript. No server-side data processing required.
WebWorkers: Heavy analytics run in background threads to keep the interface responsive without sending data elsewhere.
🔒 Zero-Knowledge Architecture
No Data Transit: Calendar events never leave your device. Our servers only handle authentication tokens and account preferences.
Encrypted Storage: Even locally, data is encrypted using your browser's built-in security mechanisms.
📊 Analytics Processing
Local Algorithms: Pattern recognition, meeting analysis, and insights generation all happen client-side.
No AI Servers: Unlike other tools, we don't send data to AI services. All intelligence runs locally in your browser.
🔄 Data Synchronization
Device-Only: Your analytics data stays on each device. No cross-device syncing that would require server storage.
Fresh Data: We fetch fresh calendar data directly from Google when you use the app, process it locally, then store insights on your device.
