OpenCube collects no data.

Last updated October 20, 2026

Meral Software does not collect usage analytics, crash reports, camera images or solve history from the app. Puzzle processing and learning work on your device without an internet connection. Purchases and optional review requests use Apple's or Google's store services.

What stays on your device

Anything the app saves, such as your history, settings or scans, is stored only in the app's own storage on your device and in your device backups if you have those turned on. Deleting the app removes its local data; device backups are managed separately through your operating system.

Device permissions

Camera — used only to read the colours on your cube while you scan. Camera images are processed on your device and are not uploaded.

Purchases

OpenCube is free to download. A single one-time purchase of OpenCube Pro unlocks additional features, with no subscription. Your store shows the price in your currency. On iPhone and iPad, Apple handles payments through the App Store. On Android, Google handles payments through Google Play. The app uses the platform's purchase services to check products and purchase status and to restore access. Meral Software does not receive your card or payment-account details. Purchases are managed separately by each store.

Third parties

The app has no advertising, analytics or tracking SDKs. Apple StoreKit and Google Play Billing and review services handle platform transactions and optional review requests under their respective privacy policies. These services may process store-account and transaction information. Puzzle, camera and learning data are not sent to Meral Software.

Children

The app does not collect personal data from children. There are no in-app accounts, ads, chat or user-posted content. Store purchases are subject to the parental controls and purchase authorization settings of your platform.

Changes

If this policy ever changes, the new version will be posted on this page with a new date. The app itself cannot contact you, so it cannot notify you.
