DUCTUS privacy

The short version

DUCTUS runs on your device. It has no account, no ads, no analytics and no subscription. It makes no network requests at all: the alphabet you forge, the notes you write and the puzzles you play never leave your phone or browser.

What the app stores

Your three drawings, the alphabet grown from them, your style settings (age, slant, weight, pen, ink, paper), the note you last wrote, your puzzle scores and which letters you have mastered. All of it lives in this browser's own local storage under one key, ductus.v1. Clearing the site's data, or uninstalling the app, deletes all of it. There is no copy anywhere else.

What leaves your device

Nothing on its own. Three things leave only when you ask, and only to where you point them:

• Cards. "Make a card" draws a picture on your device. Saving or sharing it hands that picture to your phone's own share sheet or download folder.
• The font. "Export font" builds a .ttf file on your device and hands it to the same share sheet or download.
• Hand codes. A hand code is a short string that describes your alphabet. It contains no personal information. You choose whether to paste it to a friend.

What the app does not do

• No accounts, no sign in, no passwords.
• No advertising, no ad networks, no tracking pixels.
• No analytics of any kind.
• No access to your microphone, camera, contacts or location.
• No sale or sharing of data, because there is none to sell or share.

Sharing text into the app

On a phone where DUCTUS is installed, you can share text into it from another app. The shared text is placed in the Write box on your device so you can write it in your hand. It is not uploaded.

Children

DUCTUS is a drawing and word toy suitable for any age. It collects no personal information from anyone.

Changes

If this page changes, the date at the top changes with it. Any new behaviour that would send data off your device will be described here before it ships.
