J-Card Studio does not collect, store, sell, or share any personal information. There are no accounts, no analytics, no advertising, and no tracking of any kind.
Everything you make in J-Card Studio — your designs, track lists, artwork, lyrics, notes, and settings — is stored only on your own device. Optimized Machining LLC operates no server for this app and never receives your designs or any file you create.
When you choose to use them, these features request public information directly from third-party services. Requests contain only what is needed to answer your search and are never tied to your identity:
These services receive the search terms or links you enter, subject to their own privacy policies. J-Card Studio sends them no personal identifiers, and it works fully offline for designing and printing once your content is in.
The optional subscription (a 7-day free trial, then billed monthly) is processed entirely by Apple through the App Store. Payment details are handled by Apple and never reach Optimized Machining LLC or this app. See our Terms of Use for the subscription's full terms.
Because nothing is collected, there is nothing for us to delete. Deleting a design inside the app removes it from your device; deleting the app removes all of its data. If you have any question about data, write to us and we will answer.
J-Card Studio is a general-purpose design tool. It does not knowingly collect information from anyone, including children.
If this policy ever changes, the revised version will be posted on this page with a new date.
