56I want to decide what AI does in my app

Every assisted feature, what it sends, and one switch that stops all of it

Before you start
The short version: Stash2Go uses OpenAI models for the features tagged AI, and on-device image analysis (OpenCV) for the ones tagged that way, which send nothing anywhere. Stash2Go never generates knitting or crochet patterns, and nothing you send is used to train anyone's model. The full policy is section 12 of the privacy policy.

Turn It All Off, If That Is What You Want
Assisted Features screen with the Turn AI off completely switch at the top and each feature showing what it sends

At the top of Settings → Assisted Features sits one switch: Turn AI off completely. Turn it on and every one of these features is off, hidden, and cannot be switched on. Nothing is offered and nothing is sent.

It is not on by default - because every feature underneath is already off on its own, so there is nothing to stop until you ask for something. What you had switched on is remembered: allow assisted features again and your earlier choices come back rather than being wiped.

Tip: This is the switch to reach for if you would rather not think about it feature by feature. One tap, and the whole category leaves the app.

Read What Each One Sends

Every row carries a tag and a plain sentence beginning Sends:, so you can decide without reading a policy. A card at the top counts how many you have switched on, and opens the detail of what is sent and what limits apply.

AI means the feature sends something to an OpenAI model. OpenCV means the picture is analysed on your own device and nothing leaves it.

Worth knowing
Assisted Search
Sends your search words, plus a one-off preference profile built from the public side of your Ravelry profile. Deletable, and your ordinary search is untouched.
Photo Stashing & Yarn Scanner
Send the label photo you take. The scanner keeps nothing.
Yarn Estimator
Sends the pattern and yarn details for the size you picked.
Suggested Comments
Sends the item's title, description, designer, craft, tags and yarn, plus your country.
PDF Pattern Translation
Sends only the passage you asked about, with its title and page. Never the file. Premium.
PDF Auto-Setup
Sends the pattern text, and a chart picture when you ask for one to be read. Never the file.
Colour Swatcher
Sends nothing about you. Your yarn, stash and photos are never sent.
Magazine
Sends nothing about you. The articles themselves are written with a model.
Studio
Sends the link to the yarn photo you asked about.
Bobbin
Sends your message and which screen you are on, plus up to 25 recent entries when the question needs them.
Video captions
Sends the project details, when you ask for captions.

Switch On Only What You Want

Each row is independent. Turning on Bobbin does not turn on the Colour Swatcher; turning on Assisted Search does not change your ordinary search. Switch one on, try it, switch it off again if it is not for you - nothing else moves.

A few features appear elsewhere once they are on: Assisted Search gains a card on Discover, the Magazine gains a segment in the Feed, the Colour Swatcher appears on a pattern's Yarns tab, and Auto-Setup appears in the pattern reader.

What Stash2Go Will Not Do

It does not generate patterns. Not now and not later: a knitting pattern is a designer's work, and a machine-written one wastes your yarn and your evenings. Assisted features help you search, read, and record - they do not design.

Nothing you send is used to train a model, and what is sent is listed on every row rather than summarised. If you would rather none of it existed, step 1 removes the whole category in one tap - which is the point of having it.

The complete policy is section 12 of the privacy policy. Related: App Settings, Assisted Search, Bobbin.
