Privacy Policy · Smart Seller Profit Calculator

The short version: This extension does not collect, transmit, or sell any data. Everything you enter stays on your own device. No tracking, no analytics, no ads, no account.

What we store locally

The extension stores the following information in your own browser using the chrome.storage.local API:

Your saved product calculations (names, costs, prices, computed profit and margin)
Courier presets you have added or edited
Your selected display currency (BDT or USD) and the configured exchange rate
UI preferences such as your saved-products sort order

This data never leaves your device. It is not transmitted to any server, and the extension developer has no access to it.

What we do not collect

We do not collect any of the following:

Personally identifiable information (name, email, phone, address)
Browsing or web history
Location data
Financial information or payment data
Login credentials or authentication tokens
Contact lists or personal communications
Any data from web pages you visit

Third parties

The extension contains no analytics SDKs, no advertising SDKs, and makes no network requests of any kind. It runs entirely offline. Nothing is shared with, sold to, or transferred to any third party.

Permissions

The extension requests a single Chrome permission:

storage — used solely to read and write the local data described above. It does not grant access to your browsing history, tabs, or any website data.

Your control over your data

You can manage your data at any time:

Open the extension popup → Saved tab → Clear all to remove all saved products
Use the Settings tab to reset courier presets to defaults
Uninstall the extension from chrome://extensions to remove all stored data permanently

Children's privacy

The extension does not knowingly collect any information from children under 13. Since it does not collect any data at all, it is safe for users of any age.

Changes to this policy

If this privacy policy changes in the future, the updated version will be posted at this same URL with a new effective date at the top. Material changes will also be noted in the extension's release notes on the Chrome Web Store.
