BEFORE YOU BUY
Check family access, device replacement and updates. The app license and separately purchased study decks are different products.
CHANGING DEVICES OR PLATFORMS
Moving between iPhone and Android phones, Android tablets and iPad, Windows and Mac, or tablet and desktop editions? Contact purchase support before buying again. We check the purchase channel, product, ownership, and installation and activation route on the new platform, then explain what we can support and any restrictions.
You can redownload a purchased app when it remains available for redownload and is compatible with the new device. This does not add a separate app product or another operating-system license. In-app purchase restoration depends on the product and app.
We cannot move your purchase record between Apple, Google and Microsoft, or automatically register a website purchase in a store. Using the same email address or Family Sharing does not make a different platform edition free.
These are routes that platform policies may permit. Quiz Notebook automatic platform switching and app-to-web deck linking are still in preparation and are not current purchase benefits.
| Purchase method | Possible route and restrictions |
|---|---|
| Website or reseller Our own license | Where a product supports switching, we can verify ownership, deactivate the old activation and connect the new platform. An approved installation route and applicable store conditions are required. An external purchase cannot bypass a paid-download charge. |
| Paid app download From a store | The destination store may require another purchase before installation. We do not arbitrarily transfer or cancel the original store purchase and restoration rights to move them elsewhere. Individual assistance is offered only when a supported delivery route is confirmed. A free exchange is not guaranteed. |
| Free app with An in-app license purchase | Verifying a purchase and connecting it to a Quiz Notebook account for use on another platform may be permitted, subject to policy conditions. The destination app must support the connection and meet review requirements. Billing, restoration, refunds and family access retain their original purchase-channel conditions. |
Support and procedures may change with Apple, Google and Microsoft policies, country or region, product terms and implemented app capabilities. This page will identify affected products and effective dates when guidance changes. This notice does not arbitrarily reduce agreed purchase terms or statutory consumer rights.
Include the purchase channel, product name, current platform and destination platform. We will explain the supported procedure or why the request cannot be supported.

| Channel | Family access | Direct or reseller purchase | Devices & updates |
|---|---|---|---|
| Apple iPhone · iPad · Mac | Eligible app purchases support Family Sharing. Non-consumable in-app purchases require product-specific developer support and the family’s sharing settings. Apple guidance ↗ | Purchases not billed by Apple do not qualify for Apple Family Sharing. A separate Quiz Notebook entitlement connection would be needed. | Store-installed apps use the store update channel. A directly distributed Mac app needs its own update channel. |
| Google Play Android | Eligible paid apps can be shared with up to five additional family members. In-app purchases cannot be shared through Family Library. Google guidance ↗ | We do not automatically add external purchases to Google Play purchase history. An in-app lifetime unlock after a trial does not automatically support Family Library. | Purchased apps can be reinstalled on compatible Android devices using the same Google Account. The cited guidance does not specify a common fixed app-device cap; this is not unlimited family access. Reinstallation ↗ |
| Microsoft Store Windows | Joining a Microsoft family group has not been verified to grant this app to each family member’s account. Multiple devices on a purchaser’s account and family entitlements are different. | Direct-sale and Microsoft Store entitlements are separate. Recognizing a direct purchase requires our own account and license connection. | Microsoft’s default app rules allow ten compatible Windows devices, unless the product specifies different terms. Usage rules ↗ Device management ↗ |
These services are not yet available. Supported products, limits and app versions will be published before launch.
Verify orders and attach the included products and operating systems to a Quiz Notebook account. This would not create a store receipt.
Separate accounts and private learning materials for each member. Eligible products, member limits, device limits and paid-deck eligibility are not yet decided.
View and remove registered devices, with support for lost or replaced hardware. We will publish limits before sale and preserve existing purchase terms.
Store apps use store updates; direct editions need signed installers and version notices. Maintenance updates, separate products and paid decks have distinct entitlements.
A paid-download app may require payment before you can install it and sign in. We must first provide an approved installation and activation route for direct buyers that does not require repurchasing. Do not buy again on the assumption that external purchase linking already works.
Installing on another device does not automatically transfer study data. Use supported backup, restore or sync options. A one-time purchase does not automatically include separate platform editions or every future product.
Contact purchase supportExternal access and in-app purchase links must follow platform and regional rules. Apple multiplatform services have conditions including in-app purchase availability; Google distinguishes consumption-only access from purchase flows. Microsoft allows non-game apps to use their own commerce platform.
