Read the publisher’s full description
https://tincangit.github.io/hemandhaw-study/ About Hem and Haw: This browser extension monitors when hashes of your personally identifiable information (like emails or phone numbers) are sent to third parties. How it works: 1. You enter email addresses, phone numbers, and/or other details, and press submit. 2. Hem and Haw creates hashes of these inputs. 3. When a matching hash is detected being sent to a third party, Hem and Haw takes note and logs to our server: - Type of data (e.g., email), - Hash type (e.g., MD5), - Third party's hostname, - Originating website's hostname, - Where in the transmission (HTTP request) the hash was found, - HTTP Referer, - User Agent, - Whether you use an adblock, your self-reported browser and your self-reported privacy-consciousness score At any point, you can stop Hem and Haw from searching for hashes and add/modify/delete the PII to search for. Additionally, you can see the log of detected transmissions, download the log as JSON, and clear the log. You can use Hem and Haw to see where your hashed PII is being sent from and to! What Hem and Haw does NOT collect to our server: - Your actual personal data (e.g., email addresses or phone numbers) and its hashes, - HTTP request details and data, - Any other personal information. Your IP address is also not collected by our server. IMPORTANT NOTE: Hem and Haw will clear all results when you clear all history. Data collection is approved as part of a University of Calgary research study: REB25-0355.
