You and only you can read what is sent, and nobody in between. We don’t see or hear a thing.

Access verification

Connect to Thunderbolt by verifying your domain ownership, not by more hackable password logins.

DNSSEC protection

Hackers must access your DNS records to attack you. If you enable DNSSEC, it’s almost impossible.

Frequently asked questions

Thunderbolt works like many other communication apps. The difference is that you login and connect using your domain name, and you only connect to one device at a time for extra security.

You connect your domain to Thunderbolt by verifying that you are the domain’s owner. This is done by adding custom (randomly generated by the app) TXT records to the domain’s overall DNS records. Once this is done, only the device you used to connect will be able to access Thunderbolt.

Changing your device means verifying ownership again, making it much safer than using a password. For a hacker to break into a Thunderbolt account, they need to hack the domain owner’s DNS records. A domain owner can turn on DNSSEC to help prevent this from happening.

On other messaging apps, the user needs to add an email and password. This allows the user to be logged in to multiple devices, making their account more vulnerable to being hacked. On Thunderbolt, you can only use one device, and no password is required. Some apps also store messages on the server indefinitely, which is not the case with Thunderbolt.

Imagine the Domain Name System (DNS) like the Internet’s directory. It’s the system that actually finds the websites you want to visit. It exists because people use words, like But computers use numbers, like 204.120. 0.15. The DNS connects the two.

DNS records are like your business listing with the directory. They hold key information like your IP address, mail exchange, etc.

The technical explanation is that it permits the adding and storing of text into a DNS record...The simple explanation is that it verifies your domain by adding a randomly generated code that’s exclusive to you.
DNSSEC is like an extra verification step that happens within the DNS. It identifies the right IP addresses, codes, and records whenever a domain or website is requested (searched for) online. It’s like a domain ID check.

Thunderbolt, end-to-end encrypted domain communication system, allows you to connect and make calls domain to domain. Privacy and data protection are the guiding principles behind Thunderbolt and have been considered at every step to minimize personally identifiable data collected.

Data Collected.

When you use Thunderbolt, we require and collect the minimum information to provide the service of domain-to-domain calling. The data collected/retained is similar to a call log and it is kept to provide you with a call log for reference.

This information is:

  • Domain originating the call
  • Domain called
  • Date / time of the call
Data Shared.

Thunderbolt does not share the information collected with third parties, unless we are required by law, including valid legal requests such as court orders and/or subpoenas.

Public Directory Display.

When you use Thunderbolt, your domain will be searchable in a public directory on Thunderbolt. Should you choose to not provide any personal information, only the domain name is visible and is not accompanied by personal information and/or additional information that would make the domain personally identifiable.

Choosing a Personal Name as a Domain.

You control the domain name that you use with Thunderbolt. Should you choose to use a domain name that matches your own name, this may or may not constitute personally identifiable information that links the domain specifically to you. Thunderbolt, as mentioned in this policy, does not add additional information and, thus, only the domain name is publicly seen.

However, if you choose to use your name within the domain used with Thunderbolt, you acknowledge and agree that this may constitute personally identifiable information. You further agree to display this domain publicly as part of Thunderbolt’s public directory. In addition, you acknowledge and agree that it will become part of a call log retained by you for your account and by the second party to any call you make and/or participate in as part of their call log.

Optional Directory Information.

Thunderbolt’s public directory provides the option of adding a name and image that will be associated with your domain name. These fields are optional. You may choose to provide your actual name and/or image or you can choose to use non-personally identifiable information such as a pseudonym and avatar.
