DeckAdd Privacy Policy

Last updated: October 25, 2026

DeckAdd is a Windows app for the DeckAdd touchscreen control deck. This page explains what information the app uses and how.

Information we collect

DeckAdd does not send or store any personal information on our servers. There are no usage statistics, ads or tracking. Your settings, profiles and sign-in tokens stay on your own computer; passwords and tokens are stored with Windows encryption (DPAPI).

DeckAdd account

If you create an account, this server stores your name, email address, a one-way hash of your password (never the password itself) and, if you sign in with Google / Discord / Steam, that account's ID. "Delete account" in the app permanently removes all of it. Your session token is kept on your computer with Windows encryption.

To confirm your email address we send you a confirmation email through the email delivery service Resend (Resend, Inc.); your email address is passed to that service only for this purpose. If you forget your password, the reset email you ask for is sent through the same service. An account can't be used until its email address is confirmed.

Cloud backup

If "Cloud backup" is turned on in My account, DeckAdd stores your settings (profiles, tiles, window settings, shortcuts, assistant settings, notes and reminders, your store library) and, if you choose, the images, GIFs, borders and sounds you added yourself on this server, linked to your account, so they can be restored when you sign in on another computer. Sign-in tokens of services you connect (Spotify, Discord, Twitch, Kick, Steam) and passwords are never included. You can delete the backup at any time from My account; deleting your account deletes it too.

Services you connect

• Twitch and Kick: If you sign in, DeckAdd accesses your account to show chat, get viewer counts and, when you ask, send chat messages. This data travels directly between your computer and Twitch / Kick.
• Discord: If you connect Discord, DeckAdd reads your voice state (mute, deafen, your voice channel and its members) from the Discord app on your computer and changes it when you ask. It does not read or send your messages.
• Steam: If you use "Sign in with Steam", you sign in on Steam's own page; DeckAdd never sees your password and only saves your Steam ID on your computer. To show your friends list, your friends' online status and your game achievements, the Steam Web API is queried through this server; responses are not stored. Installed games and their covers are read from the Steam folder on your computer.
• Voice assistant: When enabled, your computer's microphone is listened to on your computer for the "Hey DeckAdd" wake word; this listening sends nothing to the internet. After the wake word (or when you press "Talk"), the sentence you say is sent to this server, Cloudflare Workers AI (transcription) and Anthropic (Claude, answer); audio and text are not stored. To answer, a short context is sent with the question (time, weather, volume, the playing song, names of open programs, device profiles, notes and reminders you saved with the assistant). Clipboard text is sent only when you ask for it ("summarize / translate my clipboard"). For questions about current information DeckAdd asks public sources on your behalf (Frankfurter, gold-api.com, CoinGecko, Wikipedia, BBC News, Open-Meteo; no personal information is sent) and may search the web (Anthropic). Notes, reminders and conversation history stay on your computer. It can be turned off in Settings.
• Translate: While the Translate screen is open, text you select or copy on your computer is sent directly to the MyMemory (Translated) service to be translated, or, when MyMemory's free daily limit is reached, through this server to Cloudflare Workers AI; it is not stored. Nothing is read while the screen is closed.
• Weather: The city name you enter is sent to Open-Meteo to get weather data.

Sign-in relay

For the last step of Kick and Discord sign-in, the one-time sign-in code is passed to Kick / Discord through this server (Cloudflare Workers). Steam information is also requested (with your Steam ID) through this server. The server does not store or log the code or the returned tokens. Cloudflare may keep technical connection logs as part of its infrastructure.

Disconnecting

"Sign out" / "Disconnect" in DeckAdd deletes the tokens from your computer. You can also remove access in the "Connected apps" section of your Twitch, Kick or Discord account settings. If you choose to delete your data when uninstalling DeckAdd, all settings are removed.

Children

DeckAdd follows the age limits of the services it connects to and is not directed at children under 13.

Changes

If this policy changes, the current version will be published on this page.
