Frequently Asked Questions
Everything you need to know about Lumist Studio's local-first architecture.
How can Lumist Studio be 100% free with no monthly subscriptions?
Lumist Studio has no database servers, cloud compute, or API processing costs because it runs entirely on your local hardware. Since our cloud hosting costs are virtually zero, we don't need to rent your data back to you through a subscription model.
Does anything get uploaded to a server?
Absolutely zero. Your mockups, color palettes, kanban boards, code snippets, and timesheets are stored entirely inside your browser's sandboxed IndexedDB. We have no tracking, no analytics, and no remote servers. Your private data never leaves your machine.
Do I need an internet connection to use the suite?
Only to load each tool for the first time. To protect your bandwidth (especially on metered or cellular connections), we do not force-download the assets for all 15 apps at once. You need a connection to navigate to a tool's page, but once loaded, strictly zero data is transmitted. All image compression, color scraping, and document parsing happen entirely on your local machine.
Why do the browser extensions require permissions?
Our MV3 extensions use the most secure permission model possible: activeTab. Unlike typical extensions that demand broad, permanent 'host permissions' to read your data on every website you visit, Lumist extensions can only read the tab you are currently on when you explicitly click their icon in your toolbar.
Can I lose my local data if I clear my browser cache?
While browser storage is highly persistent, we built Lumist Safe specifically to eliminate any risk of data loss. Safe utilizes the native File System Access API to request permission to write to your local drive, performing rolling 15-minute background auto-saves of your entire workspace directly to your physical hard drive.
How can I verify that my data is genuinely staying on my local device?
We encourage you to audit us. Open your browser's Developer Tools (F12), click the 'Network' tab, and perform any action—compress an image, crop an asset, or test a regex. You will see strictly zero outgoing HTTP payloads. No analytics, no telemetry, and no third-party tracking pixels are loaded or executed.
What happens if the browser clears my IndexedDB storage? Will I lose my work?
Modern browsers treat IndexedDB as highly persistent, but storage pressure can occasionally trigger cleanup. To completely eliminate this risk, we built Lumist Safe. Safe requests persistent storage permissions from your browser and runs a background local file sync, meaning your master backups live safely in a folder on your physical hard drive, completely independent of browser cache.
Does the local folder auto-sync feature (Lumist Safe) work on all browsers?
Lumist Safe utilizes the native File System Access API, which is fully supported in Chromium browsers (Chrome, Edge, Brave, and Opera). For non-Chromium browsers (Firefox, LibreWolf, and Safari) which restrict direct directory access due to sandboxing policies, Safe gracefully degrades to a 1-click manual JSON export so you never lose your work.
