Your words, and how they’re handled.
Storymantle is a free testing version. This page describes the current product, as of September 5, 2026.
Device preview
Projects, notes, profiles, and imported text are saved in your browser’s local storage. They remain on that browser and device unless you choose to export them or bring them into a signed-in account. Clearing browser data can remove that copy. Download a backup from Your space.
Google sign-in and cloud storage
When enabled, Google sign-in provides your email address, name, and profile image to identify your account. It does not give Storymantle access to your Google Drive files. Signed-in projects are stored using Supabase, with access rules tied to your account. The service operator can administer the backend; cloud storage is not end-to-end encrypted.
Manuscripts and voice
You choose which text files to import. The first release does not continuously read or update Google Docs. Live dictation uses your browser’s speech service, which may process audio through its own provider. Storymantle saves the text you review and submit; it does not store the audio. Automated AI filing is not active in this release.
Hosting and feedback
Vercel hosts the site and may process technical request data to operate it. Feedback opens your email app; only send story details or screenshots you want to share. Storymantle does not sell your writing or run advertising trackers.
Your choices
Export a restorable backup or readable Markdown from Your space. For help accessing, correcting, or deleting cloud account data, email natwalstead@gmail.com. Please keep a separate copy of important writing while testing.
