Deckle
Privacy Policy
Effective 6 October 2026. Applies to the Deckle macOS app and these pages.
Deckle is a local Mac reader. It speaks text you paste, text recognized from a screenshot or a region of the screen, text transcribed from an audio file you drop in, or text from a link you choose. When you turn on Listen to output, it records the audio already playing on this Mac, writes that recording to a file on this Mac, and turns it into text on this Mac. A screen movie is saved only if you check that option.
What stays on your Mac
- Pasted text, dropped text or audio files, and saved audio.
- Screenshots and screen-region pictures. The direct edition uses
/usr/sbin/screencapturefor the rectangle you drag. The App Store edition captures that region inside Deckle with ScreenCaptureKit. The picture is written to a temporary file, read by on-device Vision text recognition, then deleted. It is not uploaded. - Speech. Deckle uses the
sayvoices already installed on the Mac. Audio is not sent to a speech service. - Audio already playing on this Mac, when you choose Listen to output. Deckle taps that system output. It does not use the microphone. Recognition of those words stays on this Mac. Stop writes a playable audio file under Application Support and shows it in Finder.
- The 14-day trial clock and, if you enter one, the license key. Both are stored in
~/Library/Application Support/Deckleon this Mac.
What leaves the machine
Fetching a link sends an ordinary web request to the site you named. That site sees the request and returns the page. Deckle does not send the page, the screenshot, the captured region, or the audio to a Deckle server. There is no Deckle account and no analytics SDK.
If a site answers with a browser check, Deckle can open that address in a window you control. That window is WebKit loading the site you asked for. Deckle does not solve the check and does not forward the page to anyone else.
Purchases
Deckle is a $19 one-time purchase. The direct edition keeps a local 14-day trial, then unlocks with a license key checked on this Mac. Buy $19 opens the checkout address in commerce.json when one is set. The app does not collect a card number, and pressing Buy does not mark the copy as purchased. The App Store edition stays locked until StoreKit reports the non-consumable app.deckle.mac.lifetime or a restore.
Retention & Contact
You delete pasted text with Clear, and you delete saved audio wherever you put the file. Removing Deckle and deleting ~/Library/Application Support/Deckle removes the trial clock and the license key stored there.
