Privacy Policy

Last updated: 2026-08-29

The main tool on Griduna.com runs in your browser. Drop a reference photo, overlay a drawing grid, then download PNG, JPG, or 4× PNG. The photo is read with FileReader and drawn on a canvas in this tab. It is not uploaded to griduna.com, and you do not create an account.

Hosting may keep normal server logs (IP, user agent) for a short period.

PageView

The live site loads PageView (app.pageview.app) to count page visits. It receives the page URL and ordinary browser request data. It does not receive the photo you drop or the PNG/JPG you download. Local preview builds do not send PageView events.

Feedback form

The header Feedback button sends the text you type to a self-hosted Feedback Hub on Cloudflare Workers (feedback-hub.pvb-259.workers.dev). Typical fields: type (bug, idea, question, thanks, other), message, email, page URL, language, and basic diagnostic context. Email notifications go through the configured Cloudflare email service.

The tool does not attach your file or secret. Do not paste passwords, ID numbers, or private documents.

Ko-fi

The feedback modal may link to ko-fi.com/dylan199. Opening that link is optional and uses Ko-fi’s own policy.
