No, but as far as I can tell, it’s a private company in the US (which is pretty bad for a VPN). Also, all of its features are closed-source. The encryption seems to be closed source. That should make you question their motives and integrity. And trust them not much more than Google or Facebook. For everything not privacy related, as their virtual cards and in a sense also phone numbers and email addresses (those could be private, but not using this service), this service seems fine.
From how they’re presenting themselves on their website, I would also guess their payment methods aren’t private /anonymous at all. It seems like you could even be forced to use the Apple/Google integration to pay for your subscription (which just means you can’t really pay privately).
Also, VPNs that have own apps and don’t allow access via OpenVPN are a red flag. You don’t know what their apps are doing and they don’t give you any reason to trust them either.
I use them only for voip numbers, have never used their email, credit card, vpn, etc services. For the voip numbers its been fine. Their android app is tolerable at best, I dont always get notifications for text messages, and theres no group messaging for SMS, which can cause hassles since I use one of their VOIP numbers for work. Id give it like a 6/10, I find it hard to recommend based on my experiences, although Im also not really putting in any effort to switch away from them
I also use them for voip #s. I have a calyx phone so thanks to micro g im getting the notifications as they come in. If you want to make it more private. You can buy google cards with cash at a store to upload to your google account. Also use private card service to create a virtual card for payments.
