Common questions
What applications does Zalo Design Studio support?
Two apps: Parergon, a professional metadata editor for Mac, and PromptLatch, a prompt library for Mac and iPhone. Both are supported by email at support@zalodesignstudio.com.
How do I get technical support for Parergon or PromptLatch?
Email support@zalodesignstudio.com. Every message is read by the developer who builds the apps.
I bought the PromptLatch unlock but another device still shows the trial. How do I restore it?
Use Restore Purchase inside PromptLatch on that device. The unlock is a one-time in-app purchase tied to your Apple ID, and one unlock covers PromptLatch on Mac and iPhone signed in to the same account. If Restore does not find it, confirm the device is signed in to the Apple ID that made the purchase, then email support@zalodesignstudio.com with your App Store receipt.
Where is my PromptLatch prompt library stored, and can I get it back?
PromptLatch stores your library on your Mac or iPhone, with optional iCloud sync through Apple CloudKit under your own Apple ID. You can export the whole library to JSON from the Mac app at any time, and import it again on another Mac. Zalo Design Studio holds no copy of your library, so keep your own export if the data matters to you.
What should I include in a support email?
Include the application name and version, your macOS or iOS version, what you were trying to do, what happened instead, and a screenshot or console output if the issue is visual or technical. This lets us resolve the issue without several rounds of clarification.
How do I submit feedback or feature requests?
Send feedback and feature requests to support@zalodesignstudio.com. Every suggestion is read, and requests that recur shape the roadmap.
Where can I find Parergon release notes and change history?
Release notes are published at https://parergon.io/releases/. Every version from launch to the current release is listed with features, improvements, and fixes.
