Is Coupert DE - Coupon Finder & Cashback safe?

Low risk

Coupert DE sends the full URL of each site you visit to its own API to look up coupons and cashback.

On every http/https page, the extension asks its background worker for store info, and the worker posts the page URL, including any query string, to Coupert's API, skipping a built-in list of big sites. Results are cached per subdomain for 15 minutes to 2 hours. A separate event log also sends tab URLs along with client, user and fingerprint identifiers in batches every minute.
