Privacy Policy

Last Updated: February 10, 2026

Overview

Memi is a browser extension that allows you to create and manage post-it notes on any webpage. This privacy policy explains how Memi handles your data.

Data Collection and Storage

What Data We Collect

Memi collects and stores the following data locally on your device only:

• Note Content: The text you type into your post-it notes
• Note Properties: Position (x, y coordinates), size (width, height), color, timestamps (created/updated), and minimized state
• URL Information: The web page URLs where you've placed notes (used as storage keys to display notes on the correct pages)

Where Your Data is Stored

All data is stored locally in your browser using Chrome's storage API (chrome.storage.local). Your data:

• ✅ Stays on your device
• ✅ Is never sent to external servers
• ✅ Is never shared with third parties
• ✅ Is never transmitted over the internet
• ✅ Syncs only between tabs in the same browser instance

What Data We Do NOT Collect

Memi does NOT collect, store, or transmit:

• Personal information (name, email, etc.)
• Browsing history beyond URLs where you place notes
• Analytics or usage statistics
• Device information
• IP addresses
• Any data to external servers

Data Usage

Your data is used solely for the following purposes:

1. Display your notes on the webpages where you created them
2. Persist your notes across browser sessions and tabs
3. Export your notes to text files (when you explicitly request it)

Data Access

• You: Full access to view, edit, and delete your notes at any time
• Memi Extension: Only accesses data stored by itself
• Third Parties: No access whatsoever

Data Retention

Your notes are retained indefinitely until you:

• Delete individual notes using the delete button (× icon)
• Clear all notes for a specific page using the "Clear Page" button
• Clear all notes across all pages using the "Clear All Notes" button

Data Export

You can export your notes at any time using the "Export" features in the extension popup. Exported notes are saved as plain text files to your device's download folder. This is entirely optional and initiated only by you.

Permissions

Memi requests the following Chrome permissions:

• storage: To save your notes locally in your browser

These permissions are used exclusively for the functionality described in this policy.

Security
