Hem and Haw by Tin Le

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:
- You enter email addresses, phone numbers, and/or other details, and press submit.
- Hem and Haw creates hashes of these inputs.
- 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,
Whether you use an ad blocker (based on your response).

At any point, you can stop Hem and Haw from searching for hashes, add/modify/delete the PII to search for, and see the logs of transmissions.

What Hem and Haw does NOT collect:
- Your actual personal data (e.g., email addresses or phone numbers),
- 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.
