Product: Monitor Input Keys for Windows (Stream Deck plugin) · Provider: GRAMSHIFT (Tokyo, Japan) · Last updated: 2026-09-29

Summary

The plugin does not collect, send or store any data about you or your PC. It switches the input of the monitors connected to your PC when you press its keys, and shows which input a monitor is on. It has no account, no online service, no analytics and no telemetry, and it makes no network requests.

What the plugin does on your PC

It asks Windows which monitors are connected (their display number, the model name stored in the monitor's EDID, and the device id Windows gives each monitor), so that you can choose one in a key's settings.
It talks to those monitors over DDC/CI, the control channel in the video cable, through the Windows monitor configuration functions (dxva2.dll). It reads the current input, asks the monitor which inputs it has, and, when you press a key, writes the input setting (VCP code 0x60). It never writes any other monitor setting.
For this it starts Windows PowerShell (part of Windows) as a small helper, hidden, with your Windows account and permissions. The plugin never asks for administrator rights. The helper's program text is part of the plugin; nothing is downloaded. The helper ends when the plugin ends, or ten minutes after its last request (while a key of this plugin is on screen, the key checks the monitor's input every five minutes).
It talks only to the Stream Deck app on the same PC, through a local connection (127.0.0.1) that the Stream Deck app provides to every plugin.

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 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

The plugin keeps no data of its own. Uninstalling it from the Stream Deck app removes the plugin and its log file. 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 or store data, this policy will be updated before that change is released, and the date above will change.
