Privacy Policy – Daypu: Price Comparison & Tracker

Last Updated: June 8, 2026

This Privacy Policy explains what data the “Daypu: Price Comparison & Tracker” extension (“Extension”) collects, how it uses and protects that data. By using the Extension, you agree to the practices described in this policy.

1. Information We Collect

a) User Account Information
To use the cloud-based tracking features, you are required to create an account. We collect your email address and a password. Your password is securely hashed and stored on our servers (daypu.com). We never store your plain-text password.

b) Tracked Products and History
When you choose to track a product or view its price history, the following information is stored on our servers:

• Product Name and URL
• Price information and Currency
• E-commerce site hostname (e.g., amazon.co.uk)
• Price update timestamps
  This data is used to provide you with price alerts and historical charts.

c) Local Settings
The extension stores some settings locally on your computer using chrome.storage, such as:

• Your chosen Country/Marketplace
• Your preferred Currency
• Authentication Token (to keep you logged in)
• Notification preferences

2. How We Access E-commerce Data

The extension requires permission to access various e-commerce websites (such as Amazon, eBay, Allegro, etc.) to:

• Identify the product you are currently viewing.
• Retrieve current price information to display on the widget.
• Perform cross-searches on other platforms to find the best price for you.

This data is processed locally on your browser. Only when you explicitly choose to “Track” a product or when the extension automatically updates a price for a product already in our database, is the product information sent to our servers at daypu.com.

3. Browsing Privacy

We do NOT collect, store, or transmit your browsing history. The extension only interacts with the specific e-commerce websites listed in its permissions to provide its core features (price tracking and comparison). We do not track your activity on any other websites.

4. How We Use Your Information

We use the information we collect for the following purposes:

• To provide price tracking and comparison services.
• To send you notifications when a product’s price drops (if enabled).
• To generate anonymous, aggregated price history data for the community.
• To improve the features and performance of the Extension.

Your personal information is never sold to third parties.

5. Data Security

We take the security of your data seriously. All communication between the extension and our servers is encrypted over HTTPS. We employ industry-standard technical and administrative measures to protect your account information.

6. Changes to This Policy

We may update this privacy policy from time to time. Your continued use of the Extension signifies your acceptance of the updated policy.
