+# Plebeian Signer Privacy Policy
+
+**Last Updated:** December 20, 2025
+
+## Overview
+
+Plebeian Signer is a browser extension for managing Nostr identities and signing cryptographic events. This privacy policy explains how we handle your data.
+
+## Data Collection
+
+**We do not collect any personal data.**
+
+Plebeian Signer operates entirely locally within your browser. We do not:
+- Collect analytics or telemetry
+- Track your usage or behavior
+- Send your data to any external servers
+- Use cookies or tracking technologies
+- Share any information with third parties
+
+## Data Storage
+
+All data is stored locally in your browser using the browser's built-in storage APIs:
+
+### What We Store Locally
+
+1. **Encrypted Vault Data**
+   - Your Nostr private keys (encrypted with Argon2id + AES-256-GCM)
+   - Identity nicknames and metadata
+   - Relay configurations
+   - Site permissions
+
+2. **Session Data**
+   - Temporary decryption keys (cleared when browser closes or vault locks)
+   - Cached profile metadata
+
+3. **Extension Settings**
+   - Sync preferences
+   - Reckless mode settings
+   - Whitelisted hosts
+
+### Encryption
+
+Your private keys are never stored in plaintext. The vault uses:
+- **Argon2id** for password-based key derivation (256MB memory, 4 threads, 8 iterations)
+- **AES-256-GCM** for authenticated encryption
+- **Random salt and IV** generated for each vault
+
+## Network Communications
+
+Plebeian Signer makes the following network requests:
+
+1. **Nostr Relay Connections**
+   - To fetch your profile metadata (kind 0 events)
+   - To fetch relay lists (kind 10002 events)
+   - Only connects to relays you have configured
+
+2. **NIP-05 Verification**
+   - Fetches `.well-known/nostr.json` from domains in NIP-05 identifiers
+   - Used only to verify identity claims
+
+**We do not operate any servers.** All relay connections are made directly to the Nostr network.
+
+## Permissions Explained
+
+The extension requests these browser permissions:
+
+- **`storage`**: To save your encrypted vault and settings
+- **`activeTab`**: To inject the NIP-07 interface into web pages
+- **`scripting`**: To enable communication between pages and the extension
+
+## Data Sharing
+
+We do not share any data with third parties. The extension:
+- Has no backend servers
+- Does not use analytics services
+- Does not include advertising
+- Does not sell or monetize your data in any way
+
+## Your Control
+
+You have full control over your data:
+- **Export**: You can export your encrypted vault at any time
+- **Delete**: Use the "Reset Extension" feature to delete all local data
+- **Lock**: Lock your vault to clear session data immediately
+
+## Open Source
+
+Plebeian Signer is open source software. You can audit the code yourself:
+- Repository: https://github.com/PlebeianApp/plebeian-signer
+
+## Children's Privacy
+
+This extension is not intended for children under 13 years of age. We do not knowingly collect any information from children.
+
+## Changes to This Policy
+
+If we make changes to this privacy policy, we will update the "Last Updated" date at the top of this document. Significant changes will be noted in the extension's release notes.
+
+## Contact
+
+For privacy-related questions or concerns, please open an issue on our repository:
+https://github.com/PlebeianApp/plebeian-signer/issues
+
+---
+
+## Summary
+
+- All data stays in your browser
+- Private keys are encrypted with strong cryptography
+- No analytics, tracking, or data collection
+- No external servers (except Nostr relays you configure)
+- Fully open source and auditable

+# Extension Store Publishing Guide
+
+This guide walks you through publishing Plebeian Signer to the Chrome Web Store and Firefox Add-ons.
+
+---
+
+## Table of Contents
+
+1. [Assets You Need to Create](#assets-you-need-to-create)
+2. [Chrome Web Store](#chrome-web-store)
+3. [Firefox Add-ons](#firefox-add-ons)
+4. [Ongoing Maintenance](#ongoing-maintenance)
+
+---
+
+## Assets You Need to Create
+
+Before submitting to either store, prepare these assets:
+
+### Screenshots (Required for both stores)
+
+Create 3-5 screenshots showing the extension in action:
+
+1. **Main popup view** - Show the identity card with profile info
+2. **Permission prompt** - Show a signing request popup
+3. **Identity management** - Show the identity list/switching
+4. **Permissions page** - Show the permissions management
+5. **Settings page** - Show vault settings and options
+
+**Specifications:**
+- Chrome: 1280x800 or 640x400 pixels (PNG or JPEG)
+- Firefox: 1280x800 recommended (PNG or JPEG)
+
+**Tips:**
+- Use a clean browser profile
+- Show realistic data (not "test" or placeholder text)
+- Capture the full popup or relevant UI area
+- Consider adding captions/annotations
+
+### Promotional Images (Chrome only)
+
+Chrome Web Store uses promotional tiles:
+
+| Size | Name | Required |
+|------|------|----------|
+| 440x280 | Small promo tile | Optional but recommended |
+| 920x680 | Large promo tile | Optional |

+
+**Design tips:**
+- Include the extension icon/logo
+- Add a tagline like "Secure Nostr Identity Manager"
+- Use brand colors
+- Keep text minimal and readable
+
+### Icon (Already exists)
+
+You already have icons in the extension:
+- `icon-48.png` - 48x48
+- `icon-128.png` - 128x128
+
+Chrome also wants a 128x128 icon for the store listing (can use the same one).

+
+1. **GitHub/Gitea Pages** - Host `PRIVACY_POLICY.md` as a webpage
+2. **Simple webpage** - Create a basic HTML page
+3. **Gist** - Create a public GitHub gist
+
