You've read the books. You know the advice.
Deckstack is where you practice it.
Communication strategies you rehearse like flashcards — so they're actually there when a real conversation needs them.
How often do you read great advice… and then never get to use it?
That's exactly the gap Deckstack closes: knowing → doing.
Pick as many as you like.
Pick a strategy — like starting a conversation or asking questions.
A card shows you a real situation. Pause. Visualize how you'd respond.
Flip the card for a strong example — then make it your own.
A few cards a day, and the strategies start showing up in real conversations.
Train with your ears — while walking, doing dishes, or commuting.
The situation on the card is read aloud to you.
You get thinking time to form your own response in your head.
Then a strong suggested response is read aloud — compare it with yours.
Everything is adjustable in the handsfree settings — like how much thinking time you get, the voice, and the pace.
Don’t use tomorrow what you only learned yesterday.
A strategy you’ve just met still sounds like a strategy. Let it sit, rehearse it a few times, and it starts coming out in your own voice.
Rehearse now. Use it when it stops feeling new.
Deckstack is a practice tool, not therapy or professional advice. What you say, and when you say it, is always your own call.
Deckstack is a communication training app. You've read the books — Deckstack is where you practice: rehearse communication strategies like flashcards until they show up in real conversations.
Version
Your data stays on your device. Deckstack has no accounts and keeps nothing about you on any server. Everything the app knows — your progress, favorites, settings, and unlocked content — is stored locally on this device and never sent anywhere.
No tracking. Deckstack contains no analytics, no advertising, and no tracking of any kind.
Feedback you choose to send. If you answer “Not really” when the app asks how it is going, you can write a message to the developer. Sending it transmits only the text you typed, together with the app version so the message can be placed in time. Nothing is attached to it — no name, no email, no device identifier, and nothing about your training. Writing nothing sends nothing. If you tap “Yes” instead, the app asks your device to show the App Store’s own rating dialog; whatever you do there is between you and Apple.
Speech. Handsfree audio uses your device's built-in text-to-speech, or a studio voice you have downloaded. No audio or text you produce is sent anywhere.
Studio voices. When you open Library → Voices or tap Download, the app fetches the list of voices and the voice files from voices.deckstack.app. Nothing about you is sent with the request; like any download, the server sees your network address to deliver the file. Downloaded voices stay on your device and are not backed up.
Third-party resources. The app loads no third-party resources: its icons, fonts and content are all built into the app. The only outside services it contacts are the feedback form, when you choose to send a message, and voices.deckstack.app, when you look at or download studio voices.
Backups. The Export function in Settings creates a copy of your data that only you hold. Deckstack never uploads it.
Deleting your data. Since everything is local, removing the app (or clearing its website data) permanently deletes all your Deckstack data.

You’re training with a small part of Deckstack. Pro opens the rest.
Starts with a free week.
You’ve been practising for a while now. How is it going?
That means a lot.
Tell the developer what is missing or in the way. Only the text you write here is sent — nothing else about you or your training.
Turn your phone upright
Deckstack is one column, made for one hand. It runs in portrait only.
Turning back can leave the screen able to scroll a little where it should not. If that happens, close Deckstack and open it again — nothing is lost. Locking rotation on your phone stops it happening at all.
