Is WA Number Checker – Check WhatsApp Number Registration safe?

Low risk

WhatsApp Number Checker sends your WhatsApp account ID and phone number to its service and Aliyun logging.

When used on WhatsApp Web, the extension reads the signed-in WhatsApp account ID and adds it to the extension uninstall URL sent to wasender.wadesk.io. Its analytics logging also derives the phone number from that ID and sends it with browser, platform, install, UUID, and language metadata to an Aliyun SLS logstore.
