Account information if you log in using Ravelry (username, tokens).

If you use Google-only mode, we store the account information needed to provide your Stash2Go account and sync your Google-only content across devices.

Optional data you submit, such as notes, project details, pattern favorites, or library items.

In Google-only mode, this can include project data and stash data that you create or edit in the App.

We do not store your Ravelry password. Authentication is handled by Ravelry.

When you use the App, we automatically collect:

• Device information: device type, Android version, language, screen size.
• Log data: IP address, crash reports (sent to our self-hosted GlitchTip instance for error tracking), app performance data.
• Usage data: features used, screens visited, session duration.

If you use the free / ad-supported version of Stash2Go:

Our app uses Google AdMob and Unity Ads (via AdMob mediation) to display advertisements. These services may collect certain information from your device to provide, personalize, and optimize ad delivery.

Information Collected by Google AdMob

Google AdMob may collect:

• Advertising ID (
• IP address and general location (country/region level)
• Device information (model, Android version, language, network type)
• Usage data related to ad interactions

How This Information Is Used

This data enables:

• Personalized/non-personalized ads (based on your preferences)
• Frequency capping (limiting repetitive ads)
• Fraud prevention
• Performance measurement
• Ad relevance and optimization

Data Sharing

Google AdMob and Unity Ads may share aggregated, non-personally identifiable data with their advertising partners.

Third-Party Privacy Policies

For more details on data practices, users can review:

• Google AdMob Privacy Policy: https://policies.google.com/technologies/ads
• Unity Ads Privacy Policy: https://unity3d.com/legal/privacy-policy

Opt-Out of Personalized Advertising

You have control over personalized advertising:

1. In-App Setting: You can disable personalized ads directly in the app by going to Settings → Legal & Privacy → Personalized Ads. When disabled, you will still see ads, but they will not be personalized based on your interests.

2. Device Settings: You can also limit ad tracking using your device settings:

   • Android: Settings → Google → Ads → Opt out of Ads Personalization

Note: Opting out of personalized ads does not stop ads from being displayed, but it may make them less relevant to your interests.

Ad-Free Version

You can upgrade to the premium version of Stash2Go to remove all advertisements, including Google AdMob and Unity Ads. The premium version provides an ad-free experience and additional features. When you upgrade, all advertising-related data collection by Google AdMob and Unity Ads will cease, as these services are completely removed from the premium version of the app.

To enable synchronization of your app preferences across multiple devices, Stash2Go stores certain preference data on our servers. This includes:

• Unit preferences (metric/imperial, weight units, length units)
• Color theme preferences
• Appearance settings
• Other app configuration settings

Purpose: This data is stored solely to enable cross-device synchronization and to restore your preferences if you reinstall the app or use the app on a new device.

Data Storage: Preferences are stored securely on our servers and are associated with your Ravelry username. The data is encrypted in transit and stored in a secure database.

Your Rights:

• You can export your preferences at any time via Settings → Legal & Privacy → Export Preferences (sends preferences as JSON via email)
• You can delete all server-stored preferences at any time via Settings → Legal & Privacy → Delete Server Preferences
• Deleting server preferences will remove them from our servers but will not affect your local device settings

Data Retention: Server-stored preferences are retained until you delete them or until your account is deleted.

We collect anonymized usage events (screens viewed, features accessed, session duration, and interaction context) to understand and improve how the App performs for the community. These anonymized events are sent to https://api.stash2go.com/api/events for internal usage analysis and product quality reporting. The payloads do not include your name, email, credentials, or other direct identifiers; the data is aggregated to prevent identification of individual users.

Usage analytics are enabled by default (full tracking). You can opt out at any time from within the App by visiting Settings → Legal & Privacy → Usage Analytics. When you disable usage analytics, event reporting to api.stash2go.com stops immediately and no new usage events are sent while tracking remains turned off.

Assisted features are AI features. Each one sends data through the Stash2Go server to OpenAI and receives the answer the same way; your device never contacts OpenAI directly. Every one of them is off until you switch it on, individually, in Settings → Assisted Features. Nothing sent may be used to train a model. Section 12 below states where we stand, and links our full AI policy.

Turning AI off completely. Settings → Assisted Features has a single switch that blocks the whole category: while it is on, no assisted feature runs or is offered, none can be switched on, and nothing is sent to OpenAI. Your earlier choices are remembered and return if you allow AI again. The switch is not engaged by default, because every feature is already off on its own.

What each feature sends when you use it:

• Assisted Search: your search words and the other searches in that session. On first use it also builds a preference profile from the public side of your Ravelry profile (projects, favourites, queue, public bundles, library and stash). Private and friends-only bundles are excluded, and fields Ravelry shows only to you are removed before anything is sent. The profile can be deleted at any time.
• Photo Stashing: the label photo you take while adding yarn to your stash.
• Yarn Scanner: the yarn photo you take to identify it.
• Yarn Estimator: the pattern and yarn details for the size you select.
• Suggested Comments: the title, description, designer, craft, tags and yarn of the item you are commenting on, plus your country code.
• PDF Pattern Translation: only the passage you ask about, with its title and page number. The PDF file itself is never sent.
• PDF Auto-Setup: the pattern text, and an image of a chart area when you ask for that chart to be read. The PDF file itself is never sent.
• Bobbin (craft assistant): your message and which screen you are on, and up to 25 recent entries from your stash, projects, queue, favourites, needles or library when your question requires them. Your Ravelry credentials are never sent: the App retrieves the data and passes on the result.
• Magazine: nothing about you. The articles themselves are generated with a model.
• Studio colour tools: the link to the yarn photo whose colours you ask about.
• Video captions: the project details of the video you are creating, and only when you request captions.

Trending forum themes. The Discover screen shows what the Ravelry forums are discussing. Several times a day our server groups public Ravelry forum topic titles with an OpenAI model and names each group. This uses no personal data, produces the same result for everyone, and is the only assisted feature without an individual switch; turning AI off completely removes it as well.

On-device features are not affected. Features labelled OpenCV, such as chart detection in PDF patterns, analyse images on your device. They send nothing and continue to work when AI is switched off.

None of these features send your account credentials, your messages, or your full project or stash data beyond the specific items listed above.

To help us identify, diagnose, and fix bugs and performance issues, our app uses GlitchTip (self-hosted at errors.stash2go.com) for error tracking and performance monitoring. Error data is stored on our own server and is not sent to any third-party error tracking service.

Information Collected:

When error tracking is enabled (enabled by default), the following data may be collected:

• Error messages, stack traces, and crash reports
• Device information (model, Android version, language, screen size)
• App version and build information
• User context (if you are logged in): username, first name, last name, location (city/region level)
• Breadcrumbs (user actions leading to errors, such as navigation events and API calls)
• Performance data (10% sample rate in production for performance monitoring)
• Session information (session duration, app state)
• IP address (for approximate region)

How This Information Is Used:

This data enables us to:

• Identify and fix bugs and crashes
• Improve app stability and performance
• Understand error patterns and prioritize fixes
• Monitor app health and performance metrics

Data Storage:

Error tracking data is processed and stored on our own self-hosted GlitchTip instance at errors.stash2go.com. No error data is sent to third-party error tracking services. The @sentry/react-native SDK is used for data collection, but all data is transmitted directly to our own server.

Opt-Out of Error Tracking

Error tracking is enabled by default to help us improve the app. You can disable error tracking at any time by going to Settings → Legal & Privacy → Error Tracking. When disabled, no error reports or performance data will be sent to our server. Note that disabling error tracking may prevent us from identifying and fixing issues that affect your app experience.

Trusted providers who help us:

• deliver ads (Google AdMob, Unity Ads)
• provide analytics
• track errors and monitor performance (self-hosted GlitchTip) - enabled by default, can be disabled
• operate app functionality
• provide assisted features (OpenAI) - only for the assisted features you switch on yourself, listed in section 1.6

These providers are required to protect your data.

You can disable personalized ads in two ways:

1. In-App Setting: Go to Settings → Legal & Privacy → Personalized Ads to disable personalized advertising directly in the app.

2. Device Settings: You can also limit ad tracking using your device settings:

   • Android: Settings → Google → Ads → Opt out of Ads Personalization

When personalized ads are disabled, you will still see ads, but they will not be tailored to your interests based on your activity.

You do not have to opt out, because nothing is on to begin with: every assisted feature starts switched off and stays off until you switch it on.

To switch one off again, or to shut the whole category:

• One feature at a time: Settings → Assisted Features, where each feature has its own switch and states what it sends.
• All of them at once: the switch at the top of that screen turns AI off completely. While it is on, no assisted feature runs or is offered, none can be switched on, nothing is sent to OpenAI, and the trending forum themes card is not shown. Your earlier choices are remembered if you allow AI again.
• The preference profile built by Assisted Search can be deleted separately, in the App.

When a feature is off, nothing is sent to OpenAI for it. A preference profile that was already generated remains stored until you delete it.

You can disable error tracking at any time:

• In-App Setting: Go to Settings → Legal & Privacy → Error Tracking to disable error tracking directly in the app.

When error tracking is disabled, no error reports, crash data, or performance monitoring data will be sent to our server. This may prevent us from identifying and fixing issues that affect your app experience.

If you are using Stash2Go on Google TV or Chromecast, please refer to our dedicated Google TV Privacy Policy. The Google TV version is a read-only companion app that does not display ads and only presents data from your Ravelry account.

• We never make patterns with AI. A knitting or crochet pattern must be made by a person. We will not add a feature that generates patterns.
• Every AI feature is off when you install the App. You switch on what you want. One card on the Discover screen is the single exception, and it sends nothing about you.
• One switch turns AI off completely, that card included. Then nothing runs and nothing is sent.
• Nothing that is sent may be used to train AI. Not your data, not a designer's pattern, not even information that is already public.
• The App works fully with AI switched off. Counters, charts, stash, projects, patterns: all normal.

Stash2Go does not generate knitting or crochet patterns. We will not add a feature that does. We will not help publish or sell one. A pattern must be a real human creative act. Ravelry does not allow generated patterns in its database either.

A model has never held a needle. What it makes reads like a pattern: the numbers do not add up, the shaping does not work, and nobody ever made the thing in the photo. The seller does not pay for that. A beginner does, and a first project that was never possible can end someone's crafting before it starts.

Keeping this out of a pattern database is slow human work, and on Ravelry much of it is done by volunteers in their free time. Far more of it arrives than used to. That work deserves thanks, and we will not add to the pile. Stolen patterns are the same problem: if you find one, tell the designer and report it on Ravelry.

If you are a designer. Your pattern file is never sent to OpenAI. If a reader uses translation or Auto-Setup on their own copy, only the text needed for that one job goes out, and it may not be used for training. Both are off unless the reader switches them on. We do not sell, share or republish patterns, and we never generate them.

What our features actually do. They read a pattern a person wrote: counters from your own copy, one passage explained, some arithmetic. None of them writes a pattern, and none ever will. Search results come from Ravelry's own database, so nothing generated is added to what you see. The only text a model writes anywhere in Stash2Go is the beta Magazine's articles, which are off by default and labelled. Never patterns.

AI helps with a few boring jobs. It does harm when it is used for the creative work itself. So we keep those two apart.

What we use it for: reading a yarn label from a photo, explaining one passage of a pattern in a language you cannot read, estimating how many skeins a size needs, and grouping public forum titles for the Discover screen. Small, checkable jobs where you see the answer and judge it yourself.

Why we are careful with it:

• It sounds just as confident when it is wrong. A stitch count it made up looks exactly like one a designer worked out.
• The models were trained on craft work without asking the people who made it. We cannot undo that, and we will not pretend it did not happen.
• It makes it cheap to mass-produce things that look like patterns. That is the real damage, and section 12.2 is our answer to it.
• It is pushed at people who never asked for it. Many knitters and crocheters want none of it, and that is a fair position.

Controlled, or not at all. Our rule is: help the person doing the craft, never do the craft. Either each feature has its own switch and they all start off, or one switch in Settings → Assisted Features turns the category off entirely. There is no third way where we decide for you. Nothing is on by default, no update switches anything on, and your choices are remembered and follow your account.

Stash2Go reaches OpenAI through the paid API, where data sent through the API is not used to train OpenAI's models. We have not enabled anything that would allow it, we keep nothing in order to build a training set, and we pass nothing to anyone else for that purpose. OpenAI holds a request briefly for abuse monitoring under its own API terms, then deletes it.

This holds for public information as much as private. Your projects and favourites may be public on Ravelry, and a designer's pattern is a published work. Public does not mean free to train on. If this ever changed on the provider's side, we would change this policy and say so.

No model decides anything about you. It does not judge your account, moderate your posts, set your price, rank you against other knitters, or make any choice that has a consequence for you. It answers the one question you asked and stops there.

Where a model does write something, it is marked as such: Bobbin says what it is, Magazine articles are labelled, and no answer is written into your Ravelry data unless you put it there. When something is wrong, and it will be, the designer's own words win.
