Start
Tolkr™ starts. Everything it does uses the PC's own internal address, which never leaves the machine.
- The jobReal work
A
French statement followed live, a voice tested, an 
Italian interview dubbed by two voices. - The watchEvery connection
The whole job was watched, many times a second.
- The addressesWhere each went
Each of the 43 connections went to 127.0.0.1, the PC's own address.
Every connection
The full list, including the ones that are none.
Everything that could reach outside the PC, and what it does today.
| Connection | When | What is sent | Can you block it |
|---|---|---|---|
| Meeting captions for everyone | Only when you turn it on in a meeting | The translated text, to the meeting service you already use | Yes. It is off unless you choose it |
| Licence or activation | None today | Nothing | Nothing to block |
| Updates | Never by itself | Nothing. New versions are installed with you | Nothing to block |
| Languages and voices | Never during use | Nothing. They are installed with Tolkr™ | Nothing to block |
| Usage or crash reports | Never | Nothing | Nothing to block |
| Tolkr™ at work | All the time | Sound and text, inside your systems only | It never leaves your systems |
If anything on this list changes, it is listed here before the version that changes it.
What is kept
Ordinary files, in your folders.
What Tolkr™ keeps, it keeps on your systems, in four folders you can move. Nothing is kept anywhere else.
The folders on Deployment- SessionsThe sound that was heard, the voice, the mix, every line in both languages
- MeetingsEvery meeting, both directions, line by line
- PresetsSaved setups: languages, voices, levels
- SettingsYour choices, and the history of the setup
Check it yourself
Your security team does not have to take our word.
The check is simple to repeat on your own systems, with your own tools.
- Run a real jobFollow something live, test a voice, dub a file.
- Watch Tolkr™ at workWith your firewall, your monitoring or a packet capture.
- Look for anything that leavesEverything should stay on the PC's internal address.
Asked first.
Not answered here? Ask the people who build it
Does Tolkr™ need the internet?
No. Once it is installed, it listens, translates and speaks without it.
Is any sound or text sent anywhere?
No. The only text that can leave is meeting captions for everyone, when you turn them on, and it goes to the meeting service you use.
Do we need an account?
No.
Where are recordings kept?
In ordinary folders on each workstation, which you can move.
Can we check this ourselves?
Yes. Watch Tolkr™ with your own tools during a real job.
Bring your security team.
We run Tolkr™ on one of your workstations while your team watches the network.
