The app doesn't phone home. The site doesn't track you.
This page is short because there isn't much to tell. Last updated: August 5, 2026.
The details
The application
Douga has no accounts, no telemetry, and no analytics, and it opens no network connections. Everything you draw stays on your machine. Nothing you make, and nothing about you, is ever sent anywhere.
The optional update-check plugin, if you choose to install it, asks this website for the latest version number when you pick Help → Check for Updates. The same window lists the optional add-ons, and if you press Install it downloads that add-on from this website: a file coming down, nothing going up. Neither request carries anything about you or your machine beyond what any web request carries, and nothing is stored from either. The optional extra-format add-on runs through an ffmpeg you install and control yourself.
License keys
A license key has the buyer's name and email signed into it; that is what a key is. The developer receives that name and email from the store when you buy, and keeps a record of the keys issued so yours can be reissued if you lose it and so refunds can be sorted out. That information is used for nothing else, and is never shared or sold.
Purchases
Payments are handled entirely by Paddle, the merchant of record for purchases on douga.app, under Paddle's own terms and privacy policy. The developer never sees your card number or payment details, only the name, email, and order information Paddle passes along to issue your key.
The buy page is the one page here that runs code from somewhere else. Paddle's checkout script loads on it, and Paddle's own analytics (Paddle Retain) comes down with that script. Both are Paddle's, under Paddle's privacy policy, and both load on that page only. Every other page on this site is a static file and nothing else.
This website
douga.app is static pages. It sets no cookies of its own, has no sign-in, and asks you to fill in nothing. It is hosted on Cloudflare, whose servers keep the standard short-lived request logs any host keeps. Traffic is counted with Cloudflare Web Analytics, which is cookieless and anonymous: it counts page views without identifying, fingerprinting, or following anyone.
Downloads are counted as well: a running total per file, and a total per day. That is the whole record: no address, no identifier, nothing that could be tied back to a person or a machine, and nothing that says who downloaded what. It exists so I can tell whether anyone is downloading the thing at all. The totals are public at /stats/downloads, which is a raw JSON file rather than a page: what you read there is the record itself, not a picture of it.
If you write to [email protected], your message is used to answer you and for nothing else. No mailing lists, no marketing.
