Privacy Policy for PonnoRadar

Effective Date: November 6, 2026 • Manifest V3 Compliant • Version 0.2.0

This Privacy Policy applies to the PonnoRadar: Price Tracker & Deals browser extension for Google Chrome and Chromium-based browsers, developed by Code Burst Pro ("we", "us", or "our"). We design our tools with a strict privacy-first, local-first architecture. Your browsing history, shopping watchlists, and personal finances remain strictly your property.

1. Single Purpose Statement & Principles

In compliance with the Google Chrome Web Store Single Purpose Policy, the sole purpose of PonnoRadar is:

"To provide real-time price comparison, price drop tracking, and shopping deal intelligence for online shoppers browsing Bangladeshi e-commerce and retail websites."
  • We never sell, rent, or monetize user data or browsing activities to data brokers, ad networks, or third parties.
  • We do not use advertising SDKs, tracking pixels, browser fingerprinting, or invasive analytics cookies.
  • We do not evaluate creditworthiness or determine financial eligibility.
  • We do not require registration; PonnoRadar runs fully in private guest mode out-of-the-box.

2. User Data Disclosure & Classification

To maintain complete transparency with our users and Web Store reviewers, the table below categorizes our data handling:

Data Category Status Detailed Description
Personally Identifiable Information (PII) NOT Collected We never ask for or collect names, email addresses, phone numbers, home addresses, or identification numbers.
Health Information NOT Collected None.
Financial & Payment Data NOT Collected We never access or collect credit card numbers, bank credentials, payment gateway sessions, or transaction accounts. Optional Spend Lens purchase receipts entered by the user are stored strictly on the local device.
Authentication Credentials NOT Collected No account passwords or session PINs are harvested. The extension operates in local guest mode.
Web Browsing History NOT Collected PonnoRadar does not track, record, or compile lists of websites you visit. Non-shopping websites are completely ignored.
User Activity & Keystrokes NOT Collected No mouse movements, scrolling recordings, or keystroke loggers are present.
Website Content (Product Details Only) Handled Locally On supported Bangladeshi merchant product pages only, the content script reads the active product title, retail price, stock availability, and merchant domain. This is used exclusively to query our price database and show competing retailer deals.

3. Local-First Storage Architecture (`chrome.storage.local`)

PonnoRadar uses your browser's private local sandboxed storage (chrome.storage.local). The following data is preserved locally on your machine and is never synced to external servers without your explicit initiation:

  • Watchlist Items: Product IDs, titles, thumbnail images, and target alert prices that you specifically choose to track.
  • Price Alerts: Target drop thresholds and alert notification flags.
  • Spend Lens Records: Optional shopping expenses and receipts that you manually record or import via CSV to analyze personal spending.
  • User Preferences: Dark/light mode theme selection, quiet hours notification schedule, and cached store price comparisons for instant offline performance.

4. Chrome Extension Permissions & Technical Justification

Every permission requested by PonnoRadar in its manifest.json is strictly necessary to fulfill its core functionality:

tabs

Required to detect when the user is on a supported Bangladeshi retail product page, refresh active price checks, and open competing store product links in a new tab upon user click.

activeTab

Enables temporary, secure access to the active merchant product page when the user opens the popup or interacts with the in-page comparison card.

storage

Used to locally store the user's saved watchlist items, target alert thresholds, user preferences, and private Spend Lens expense records on their own device.

alarms

Used to schedule low-frequency background checks for price updates on items saved in the user's price-drop watchlist, while respecting configured quiet hours.

notifications

Used to trigger native browser/desktop alerts when an item on the user's watchlist drops below their designated target price.

contextMenus

Provides convenient right-click options for users to quickly search selected product text across PonnoRadar or add the current item to their price tracker.

sidePanel

Allows the extension to provide a persistent side panel companion UI in Chrome 116+ so users can compare store listings side-by-side with active tabs.

host_permissions & content_scripts

API Endpoints: https://www.ponnoradar.com/* • Required to query public price comparisons, fetch historical price sparklines, and download verified coupon codes.
Retailer Domains: Explicitly scoped to supported Bangladeshi shopping domains (e.g., startech.com.bd, daraz.com.bd, ryans.com, techlandbd.com, applegadgetsbd.com, etc.) to detect product listings, extract pricing, and display the isolated deal badge. No arbitrary web access is requested.

5. Content Script & Shadow DOM Security

PonnoRadar injects a lightweight product assistant badge exclusively on verified product pages of supported retailers.

  • Shadow DOM Isolation: All extension UI elements (floating deal pill, comparison modal) are rendered inside a closed Shadow DOM boundary to guarantee that extension styles never interfere with retailer checkout pages, and retailer scripts cannot read extension memory.
  • Non-Disruptive Shopping: The extension never blocks store checkout forms, payment processing buttons, or login inputs.

6. Zero Remote Code Execution Guarantee

In strict compliance with Manifest V3 policies:

  • PonnoRadar contains NO remote JavaScript, WebAssembly, or external script loaders.
  • All code, styling, icons, and logic are 100% packaged inside the extension archive (.crx / .zip) reviewed and verified by Google.
  • Dynamic code evaluation mechanisms (such as eval() or string-based timers) are completely disabled and prohibited.

7. User Data Sovereignty & Deletion Rights

You have unconditional ownership of any data stored by PonnoRadar:

  • Full JSON Export: You can export your entire watchlist and Spend Lens history at any time as a structured JSON file via the Settings/Options page.
  • One-Click Wipe: The extension provides an instant "Clear All Data" button that permanently purges all local storage entries immediately.
  • Uninstallation: Removing PonnoRadar from Google Chrome completely and instantly purges all extension storage from your device.
