Hooknest Privacy Policy

Effective date: 2026-11-10

Hooknest is a crochet companion app: it lets you follow a crochet pattern line by line, count rows, stitches and repeats, keep notes and a photo for each project, learn basic stitches, browse free beginner patterns, look up hook sizes, yarn weights and abbreviations, calculate gauge, and use a home screen widget and reminders (the "app"). It is provided by DDJ A1 ("we", "us"). This policy explains what data the app handles and how. Hooknest has no account system and we do not run a server for it. Everything you create in the app stays on your device.

Data stored on your device

Your projects (name, pattern text you type or paste, current line, row, stitch and repeat counts, hook and yarn notes, notes, color choice and dates), any project photo you choose, and your settings (theme and reminder choices) are stored only on your device. They are not sent to us. When you add a photo, you pick it with Android's photo picker; the app saves a smaller copy inside its own storage and does not access the rest of your photos. Uninstalling the app deletes this data from your device. If device backup is turned on, Android's standard app backup may include this data in your own Google account backup. That backup is controlled by you and Google, not by us.

Sharing a project card

When you tap Share card, the app creates an image of your finished project (photo or color, name, row count and days) and opens the Android share sheet. Nothing is sent unless you choose an app to share it with; what happens next is up to that app.

Permissions the app asks for and why

• Notifications (optional). Used for an occasional reminder to pick up your project. You can decline and every feature still works.
• Run at startup. Lets reminders come back after your phone restarts or the time zone changes.
• Vibration. Used only for reminder notifications if you keep notification vibration on.
• Internet access, network state and the advertising identifier (AD_ID). Used only by the advertising components described below. Every crochet feature in the app works offline.

The app does not request your location, the camera, microphone, contacts, or access to all your photos and files.

Information collected automatically

When you use the app, third-party SDKs used for advertising may collect some information automatically, including:

• Your device's Internet Protocol (IP) address, which may be used to estimate your approximate (general) location
• Device or other identifiers, such as your device's advertising identifier (Advertising ID) and app set ID
• App interactions, such as session time, screens viewed, and ad views and taps
• Crash logs and diagnostic information, such as your device's operating system and model, and ad performance data

The advertising SDK collects this information and shares it with Google (AdMob) and its advertising partners for advertising, analytics, fraud prevention, security and compliance. It is encrypted in transit. The app itself does not send your projects, patterns, photos or settings off your device, and we do not link the advertising data to them.

Advertising

The app shows advertisements from Google AdMob:

• a banner at the bottom of most screens (not on the screens where you type a project or use the gauge calculator)
• an ad when the app starts from the launcher
• full-screen ads only at natural breaks: after you save a new project, after you mark a project as finished, and when you open a free pattern
• an ad in the exit dialog
• optional video ads you can choose to watch from Settings to see fewer ads for 24 hours

A full-screen ad never appears while you tap the counters, move between pattern lines, switch tabs, or use the widget or a notification. To serve ads, AdMob and its partners may access your device's Advertising ID and the information described above. In the European Economic Area (EEA), the United Kingdom and other regions where required, the app shows a consent form through Google's User Messaging Platform (UMP) before personalized advertising data is used. If you decline, you are shown non-personalized ads instead. You can reset or limit ad personalization at any time in your device settings (Settings → Google → Ads), and you can change your consent choice from the app's Settings screen.

For more information on how Google uses data when you use partners' apps, see https://policies.google.com/technologies/partner-sites.

Children

Hooknest is a general-audience app and is not directed to children under 13. We do not knowingly collect personal information from children.

Your rights

Your app data exists only on your device, so you control it directly: you can edit or delete any project in the app, and uninstalling the app removes everything the app stored. Depending on where you live (for example under the GDPR in the EEA/UK or the CCPA in California), you may also have rights over data processed by advertising SDKs. You can exercise your ad choices through the consent form and your device's ad settings described above.

Changes

We may update this policy. Material changes will be reflected on this page with a new effective date.
