When a site asks you to log in with Google, you should expect basic transparency in return. Updater.voyagerinnovation.com offers almost none. There is no about page, no contact information, no privacy policy, and no terms of service. The domain owner is hidden from public WHOIS records, and the site has no history in the Wayback Machine — meaning we can't see what it looked like even a week ago.
For any SaaS or app that handles user authentication, these are not minor omissions. Legitimate services nearly always publish a privacy policy explaining what data they collect through your Google login and how they use it. Without that, you are handing over access to your Google account information with no understanding of where it goes.
Updater.voyagerinnovation.com has clean security certificates and no malware flags, but that's like a car having working headlights while the driver hides their face and won't tell you where you're going. The technical basics are fine, but the trust fundamentals are missing. If you're wondering whether updater.voyagerinnovation.com is safe, the short answer is that there is not enough information to trust it with a login. A site that won't say who runs it or what they will do with your data is not worth the risk.
