Short version: your footage, projects and API keys stay in your browser. We count visits with analytics. We have no accounts and no upload storage.
Your Files
The editor runs in your browser. Footage you import is read on your device and kept in your browser’s private storage for this site, renders happen on your device, and saving or rendering creates a download on your device. The Site has no upload endpoint and no storage for your projects or media.
AI Panel
When you use the AI panel, your browser sends the prompt and the image or frame you picked directly to the provider you selected (OpenAI, Google, OpenRouter, or the custom endpoint you entered), authenticated with your API key. These requests do not pass through our servers. The provider’s privacy policy applies to that data.
Your API key is stored in your browser: in sessionStorage (cleared when the tab closes) by default, or in localStorage if you tick “Remember my key on this device”. “Forget all keys” in the panel deletes it.
Data Stored in Your Browser
EffectCraft keeps its settings, your current session, saved projects, imported media, auto-saves and a frame cache in your browser’s storage for this site (the Origin Private File System, or IndexedDB). Its service worker keeps a copy of the app files so it opens offline. Folders you open in the Media Browser are remembered as browser permissions, not copied. The AI panel stores your chosen provider and model in localStorage. None of this is sent to us. You can clear it in the app (Settings › Disk › Browser Storage) or by clearing this site’s data in your browser.
Analytics
We use Umami, which does not use cookies, and Google Analytics, which does set cookies, to count page views and a few anonymous events such as opening the AI panel or running an AI request (provider name and success or error only). Events never include your footage, frames, prompts, file names or keys. Google’s use of this data is described in its privacy policy.
Hosting
The Site is served by Cloudflare, which processes standard request data such as IP addresses to deliver pages and app files and to protect against abuse.
If you email us, we receive your address and message and use them only to reply.
Changes
We will post any changes to this policy on this page with a new effective date.
