CubeLens scans and solves a 3×3 cube and offers on-device tutorials. You do not register, sign in, or receive an app account. On iOS, we generate a random visitor UUID, keep it in the Keychain, and send it to our server to count visitors and recognize returning installations. We do not use advertising identifiers or third-party analytics/tracking SDKs.
Camera frames are processed entirely on your iPhone by the models included in the app. Frames and recognized cube colors are not uploaded. Camera frames are not saved or retained after scanning. You may decline camera permission and use Fill Colors or Play.
| Information | Purpose and recipient | Storage |
|---|---|---|
| Camera frames | Recognize cube colors entirely on your iPhone. | Only transient device memory; never uploaded, saved or shared. |
| Random visitor UUID and first/most recent visit times (iOS) | Our server counts distinct visitors and recognizes a returning installation when the same Keychain UUID is available. The UUID is not linked to free-use counts or Apple subscriptions and is not shared for advertising. | UUID in the local Keychain, without iCloud synchronization; UUID and visit times on our server until deleted. Deleting/reinstalling the app may preserve the UUID; if it is unavailable, a new UUID is generated. |
| Successful scan/solve counts and temporary event keys | Apply the free-use limit and prevent duplicate counting only on your iPhone; never uploaded or shared. | Local app data; retained across normal updates and restarts, cleared when the app is deleted. Old Keychain counters are discarded when switching to local storage. |
| Apple transaction ID when verifying a purchase, restoring it, or refreshing a known subscription | Our server asks Apple to verify the transaction and current subscription. Apple handles payments; we never receive card details, your Apple Account login, name or email. | Transaction requests are processed to return subscription status. We do not create user accounts or associate a subscription with a device identity. |
| Apple subscription notifications: transaction IDs, product, purchase/expiry dates, renewal, refund and environment status | Apple sends signed notifications to our server for purchase support, security and subscription diagnostics. | Signed notification records on our server; kept as needed for subscription support, security and legal obligations. Contact us for access or deletion; legally required records may be retained. |
| Diagnostic/server logs: App version, OS version, language and time zone; request IP, service, time and error information | Our server uses this information for compatibility, troubleshooting and abuse prevention. No persistent device identifier is included. | Request metadata is processed with the request. Service logs contain request IP, time, operation and error information and are retained under server log rotation. |
Successful scan and solve counts and temporary event keys stay in local app data, not the Keychain. They are not uploaded or synchronized across devices. Deleting the app clears these records; reinstalling starts the counts at zero. Offloading the app while keeping its data does not reset them. Restoring a device backup may restore local app data. Preferences, subscription status and a known Apple transaction ID are cached locally to restore access and check subscription status. No tutorial progress is sent to a server.
Purchase records use Apple transaction/subscription identifiers, and diagnostic logs include request IP addresses. These data are disclosed as linked data in App Store privacy details. They are not used for advertising or tracking, and do not create a CubeLens account. The separate random visitor UUID is disclosed as a linked device identifier, with visit times used for analytics; it does not restore free-use counts.
We share purchase identifiers only with Apple for verification. Our infrastructure hosts visitor UUIDs and visit times, request logs and signed Apple notification records. We do not sell information, track you across apps or websites, or use collected data for advertising. App/server traffic uses TLS and request signatures. The service is hosted in the United States; using it may transfer the limited data above there.
Camera permission can be changed in iOS Settings. Contact us for access, correction or deletion of server records and provide the relevant Apple transaction information so we can locate the record. We respond within 30 days. There is no CubeLens account to delete. Removing local app data or contacting us does not cancel an Apple subscription; manage it in Apple Subscriptions. Apple processes refunds through Report a Problem.
CubeLens is a general-purpose utility and is not specifically directed to children under 13. Contact us if you believe a child has provided personal information. We publish policy changes here with an updated date.
