Privacy

The short version

The Sheet Maker, Sheet Cutter, GIF tools and Image to Pixel Art converter run entirely in your browser tab, using your device's Canvas implementation. Your images are decoded, processed and re-encoded locally. They are never uploaded to us or to anyone else, and nothing about them is stored: close the tab and they are gone.

What we collect

• No accounts. There is nothing to sign up for.
• No file storage. We have no server-side copy of anything you process — there is no server-side processing at all for the tools.
• Preferences only. The language toggle stores one value (sb-lang) in your browser's localStorage so the UI remembers EN/中文. That is the only local storage this build sets.
• Analytics: none are embedded in this build. If privacy-friendly, aggregate analytics are added later, this page will be updated before they ship.

The AI Beta boundary

The AI Sprite Generator is the one feature that cannot be local: text-to-image generation happens on a model provider's API. In this build the generation backend is not connected and the Generate button sends nothing anywhere. When it is connected, the page will state — at the point of generation — that your prompt and any reference image you attach are sent to the model API, and only successful generations will count against a daily per-visitor limit. The pixel post-processing demo on that page is fully local, like the other tools.

Third-party requests

This build loads no external fonts, trackers or CDNs; the pages and tool code are served as static files. Sample images shown on the site are our own test outputs, labelled as samples.
