FAQ
Does it support offline writing?
Yes. Marlin is Local-First by design. Your notes live in IndexedDB on your device, meaning you can search, write, and edit with 0ms latency even without an internet connection. Changes sync automatically to GitHub once you are back online.
Where is my data stored?
Your data lives in your own GitHub private repository. We do not host, scan, or sell your notes. Marlin acts as a privacy-focused interface for your Git repo. Even if Marlin shuts down tomorrow, your data remains safe in your GitHub account.
What if I hit GitHub API rate limits?
It's highly unlikely. Marlin writes to your local database first and batches syncs intelligently. We also use ETag caching to prevent unnecessary requests. You can write thousands of notes without worrying about API quotas.
Can I export my data?
You don't need to "export." Since Marlin syncs directly to your repository, your notes are already stored as standard Markdown files. You can `git clone` your repo anytime and open them in VS Code, Obsidian, or any text editor.
