Summary

Your drive stays on your PC. The plugin does not collect or send any data about you or your computer. While one of its keys is on your Stream Deck, it reads values of the train you drive from Train Sim World running on the same PC, keeps the latest values in memory and draws them on your keys. When you press a Cab Button or a Custom Control, it sets that one control of your train. It has no account, no online service, no analytics and no telemetry of its own, and it never sends anything over the internet.

What the plugin does on your computer

It connects only to Train Sim World on this PC (address 127.0.0.1), on port 31270 or on the port you enter in a key's settings, through the interface the game itself offers to programs on the same PC when it is started with -HTTPAPI.
To be let in, it reads the access key the game writes to Documents\My Games\TrainSimWorld…\Saved\Config\CommAPIKey.txt (or uses the key you paste in the settings) and sends it only to the game on this PC. To find your Documents folder, it reads the folder's location from the Windows registry with the Windows tool reg. The key is never shown, logged or sent anywhere else.
It reads values of the train you drive only (for example its speed, the speed limit, the next signal and station, the handles, the brake gauge, the game time and service, and the controls of the train and their positions) and keeps only the latest values in memory while the keys are shown. They are not written to disk. The game's answer that carries the service also carries your player profile name: the plugin receives it with that answer but does not use, show or store it.
It sets one control of your train when you press a Cab Button or a Custom Control, and, for a held control, sets it back to where it rests when you let go of the key (sent again until the game takes it, also when the plugin quits). It changes nothing else in the game, and it does not send keys or mouse input to the game or to any other program.
While the game does not answer, it checks from time to time whether the game's program (TrainSimWorld.exe) is running, with the Windows tool tasklist, so that a key can say "the game runs but its interface is off". Only the answer yes or no is used; the list of programs is not stored or sent.

Purchases

The plugin is sold on the Elgato Marketplace. Purchases, payments and licenses are handled by Elgato (Corsair) and its payment provider under Elgato's own terms and privacy policy. GRAMSHIFT never receives card details. If Elgato provides us with sales records (for example the date, country and amount of a sale), we use them only for accounting and tax.

Support requests

If you contact us, we receive what you choose to send (for example your email address, your message and any screenshots). We use it only to answer you. Email to contact@gramshift.com is forwarded by our email forwarding provider (ImprovMX) to a mailbox hosted by Google (Gmail), so those providers process support emails on our behalf. Please do not send passwords, the game's access key or other secrets.

Our role and legal basis

The plugin works only as a tool on your own computer: GRAMSHIFT does not receive or process anything from it. For sales records and support emails, GRAMSHIFT is the controller. We rely on our legitimate interest in answering requests and on legal obligations (for example tax records). GRAMSHIFT is based in Japan, so this information is processed in Japan and by the providers named above.

Your rights

You can ask us to access, correct or delete personal information we hold about you, or object to its use, by emailing contact@gramshift.com. If you are in the EEA or the UK, you can also complain to your local data protection authority.

Retention and deletion

Uninstalling the plugin from the Stream Deck app removes the plugin and its log file; removing its keys removes their settings, and emptying the API key field removes the pasted key. The plugin keeps no other data. Support emails are kept only as long as needed to handle the request and meet legal obligations; you can ask us to delete them. Sales records are kept for up to 7 years for accounting and tax.

Changes

If the plugin ever starts to send data or store other data, this policy will be updated before that change is released, and the date above will change.
