Product: Window Peek for Windows (Stream Deck plugin for Windows) · Provider: GRAMSHIFT (Tokyo, Japan) · Last updated: 2026-09-28

Summary

Pictures of your windows and your screen never leave your PC. The plugin takes pictures of the window or the part of the screen you chose, only to draw them on your Stream Deck keys. It does not send them, or anything else about you or your PC, to GRAMSHIFT or anyone else, and it does not write them to disk itself. 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

For each key, it takes a small picture (144 × 144 pixels) of the window or the screen region you chose, every 0.5 to 30 seconds as you set it, and only while that key is visible on your Stream Deck. It stops when the key is not shown (another page or profile), when you pause a Screen Region key, and when the Stream Deck app closes.
To take the pictures it starts one helper process: Windows PowerShell, which is part of Windows, running a small piece of code that comes inside the plugin. It uses the Windows functions that list windows and ask a window to draw itself (PrintWindow) or copy a part of the screen. It runs as your Windows user and never asks for administrator rights. When it starts, Windows PowerShell compiles that code, which briefly creates temporary files (the code, not any picture) in your Windows temp folder.
The pictures go only to the Stream Deck app on the same PC (through the local connection, 127.0.0.1, that the Stream Deck app provides to every plugin), which shows them on the keys. The plugin keeps only the latest picture of each key in memory and never writes a picture to disk itself. What the Stream Deck app does with the key images it receives (for example whether it keeps the last image of a key with your profile) is up to the Stream Deck app, like for any other plugin.
For Alert When Idle, it compares each picture with the previous ones using a tiny 32 × 32 brightness grid, in memory, to tell whether the window changed.
While the PC is locked (or the Windows sign-in, Ctrl+Alt+Del or administrator prompt screen is shown), it takes no picture at all and removes the pictures from the keys; they come back after you sign in again.
It does not show a window that is minimized, and it never takes a picture of a window whose app asks Windows not to be captured (for example some password managers and chat apps).
A press on a Peek Window or Alert When Idle key brings the chosen window to the front, like clicking it in the taskbar. The plugin does not type, click or change anything in any window.

Where data goes

Data	Where it is processed	Stored by the plugin?
Key settings (label, the program name and the title of the chosen window (the whole title as it was when you chose it from the list; you can shorten it to a part), its window number, the screen region, how often, how long to wait)	Saved by the Stream Deck app on your PC, like the settings of any other key	Only in your Stream Deck profile on your PC.
Pictures of the chosen window or screen region, and their brightness grids	On your PC: taken by the helper process, drawn on the key by the Stream Deck app	Not by the plugin: only the latest one per key, in memory; gone when the plugin stops. The plugin never writes them to disk or sends them anywhere. (The Stream Deck app receives them to show them on the keys.)
The list of open windows (program names and titles), shown in a key's settings to choose from	On your PC, only while the settings are open	No (only the window you choose is kept, in the key's settings).
Technical log	The Stream Deck plugin framework writes a small log file (mainly connection errors) in the plugin's folder on your PC. The plugin does not write pictures, window titles or screen contents to it.	On your PC only. It is not sent anywhere.
Anything sent to GRAMSHIFT servers	—	Nothing. The plugin has no server of its own and makes no network requests.

Note: the pictures are shown on your Stream Deck, which people near you can see. Choose windows accordingly, and use the pause of a Screen Region key or another Stream Deck page when you share your desk or your screen.

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 check screenshots of your keys or screen for private content before you send them.

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.
