Privacy Policy

Effective 12 November 2026

MotionField Live Wallpaper (“MotionField”) is made by SI Devworks. This policy explains what MotionField handles and where it goes. SI Devworks is the data controller for any personal data we receive.

Without an account

MotionField works fully without an account, and then we collect nothing. There are no analytics, advertising, tracking or crash reports. Your chosen look, settings, saved designs, background images you add and blocked creators stay on your device (Mac, iPhone, iPad or Android phone) in the app's own storage.

MotionField for iPhone, iPad and Android

The phone and tablet apps work the same way as the Mac app: with no account they collect nothing, and with an account they sync the same data described below. On iPhone and iPad, saving a look adds a Live Photo or still image to your photo library; the app can only add to Photos and never reads your library. Background images you choose come through the system photo picker, which gives the app only the photos you pick. On Android the app is a live wallpaper drawn on your phone and needs no permissions beyond internet access for the optional account and marketplace.

MotionField for Chrome

The MotionField themes for Chrome collect nothing and send nothing to us. The MotionField Live Wallpaper extension collects nothing either unless you choose to sign in to a MotionField account in it (version 1.1 and later). Neither has analytics, advertising or tracking.

• Your look and settings (clock, search box, 24-hour time, motion, frame rate and resolution) are saved with Chrome's own storage. If you're signed in to Chrome with sync turned on, Google syncs them to your other computers under your Google account; we never receive them.
• Searches you type in the New Tab search box go straight to the default search engine you chose in Chrome, through Chrome itself. MotionField doesn't see, store or send them anywhere.
• If you sign in (optional), the extension sends your email address and password to Google Firebase to sign you in, keeps a sign-in token in Chrome's local storage, and reads and writes your account's synced settings: your chosen look and, when you pick one, the design you applied. It also reads whether your account has Premium. This is the same account data described below; nothing else about your browsing is sent. Sign out in the extension's settings to stop, or delete your account from any MotionField app.
• The extension's permissions: “storage” saves the settings above, “search” hands your search to your own search engine, and access to Google's sign-in and Firestore addresses is used only for the optional account. It can't read your browsing or the pages you visit.
• The “Get MotionField for Mac” link opens the App Store page in a new tab; Apple's privacy policy covers that page.

To remove everything, remove the extension from chrome://extensions, which deletes its saved settings.

If you create an account (optional)

An account keeps your settings and saved designs in step across your Macs, and lets you publish designs or report one. You can sign in with Apple or with an email address and password. We store, in Google Firebase:

• Your email address, or the private relay address Apple gives us if you choose to hide yours, and an account ID. Firebase stores passwords in a protected, hashed form; we never see them.
• Your synced settings: your saved designs, your chosen look, your frame rate, resolution and pause choices, the creators you've blocked and your creator name, so they appear on any Mac where you sign in. Only your account can read them.
• Your background images: photos or pictures you add to your own designs, re-saved by the app as JPEG, so your designs look the same on every Mac. Only your account can read them.
• Designs you submit: the design's name and settings (style, colours and effect), its background image if it has one, the creator name you choose, its price, its review status and when you submitted it. Once approved, a design and its creator name are public in the marketplace.
• Reports you make: which design you reported, the reason, and your account ID.

Your sign-in is kept in your Mac's Keychain. We use this data only to sync your settings and run the marketplace. We don't sell it, share it with advertisers, or use it to track you.

Purchases

Purchases are made through the App Store on Mac, iPhone and iPad, and through Google Play on Android. Apple or Google processes the payment, and we never see your card or payment details. The app checks with the store whether you own Premium.

If you're signed in to a MotionField account when you buy or restore Premium, the app sends the store's signed proof of purchase to our server, which checks it with Apple or Google and records against your account that you have Premium, which store it came from, and the store's transaction or order number, so Premium also unlocks on your other devices and can't be claimed by another account. These records are deleted with your account.

Where it's stored

Account data is held by Google Firebase (Google Cloud), with synced settings, images, designs and reports stored in the United Kingdom (europe-west2). Google processes it on our behalf and encrypts it at rest.

How long we keep it

We keep account data, synced settings and designs until you delete them. Reports are deleted once we've reviewed them.

Deleting your account

On the Mac, open Account… in the MotionField menu (or the account button at the top of the gallery) and choose Delete Account. On iPhone, iPad and Android, open Account and choose Delete account. You can also email us to ask for deletion (see Contact). To delete some of your data without deleting your account: removing your design from the marketplace deletes it and its image from our servers straight away, and deleting a design from your library removes it from your synced settings. Background images you synced are kept until you delete your account, or until you email us to delete them. This deletes your account, your synced settings and images, and all your submitted designs straight away. If you signed in with Apple, MotionField also asks Apple to revoke its access. Settings and designs on your devices stay there until you delete them or remove the app.

Your rights

You can ask to see, correct, export or delete your data, or object to how we use it, by emailing sary@sidevworks.com. We'll reply within 30 days. You can also complain to your local data protection authority.

Children

The marketplace is not meant for children under 13, and we don't knowingly collect their data.

Changes

If this policy changes, we'll update this page and its date. For significant changes we'll also tell you in the app.
