Privacy Policy
The short version: DataReceipt collects nothing. No data ever leaves your device. The extension works entirely locally inside your browser.
What DataReceipt does
DataReceipt monitors network requests made by websites you visit to identify known advertising and tracking domains. It calculates an estimated monetary value for your browsing data based on publicly available advertising revenue data (annual reports FY2023 — sources: Alphabet, Meta, IAB, eMarketer).
All detection, calculation, and storage happens exclusively inside your browser
using the browser's built-in chrome.storage.local API.
Data we collect
None.
- We do not collect your browsing history.
- We do not collect personal information.
- We do not use analytics or crash reporting services.
- We do not make any network requests of our own.
- We do not transmit any data to any server, ever.
Data stored locally
DataReceipt stores the following data locally on your device using
chrome.storage.local:
- Aggregated tracker counts and estimated revenue values per corporate entity
- Your selected language and currency preferences
- Whether the extension is enabled or disabled
This data never leaves your browser. You can delete it at any time using the Reset button in the extension overlay, or by uninstalling the extension.
Permissions explained

Third-party services
DataReceipt does not integrate any third-party services, SDKs, or analytics platforms. The only external library included is jsPDF (MIT license), used solely for generating PDF exports on your device.
Children's privacy
DataReceipt does not collect any data from anyone, including children.
