1. In one line
UFDI does not send your files anywhere. There is no account, no sign-in, no tracking and no usage analytics in the program. Everything, including background removal and text recognition (OCR), runs on your computer. The program uses the internet only when you choose to: to download an optional AI model (section 3b), and to show sponsored pictures if you switch them on (section 3c). Neither sends photos, file names or personal data.
The website (section 3d) counts page views and downloads without cookies and without storing IP addresses, and may show advertisements.
2. Personal data the program collects
None. UFDI does not collect, store or transmit names, e-mail addresses, phone numbers, device identifiers, location data or usage history. No account and no sign-in is required to install, run or use it.
2a. Personal data processed when you contact us
If you write or call using the details above, we process what you send us, for as long as it takes to answer you. You provide this yourself; the program does not collect it.
| Data | Purpose | Retention |
|---|---|---|
| Your e-mail address or phone number, and anything contained in your message | receiving and answering your enquiry | one year after the enquiry is closed, or immediately on your request |
This is never used for anything else and is never passed to a third party.
3. Your files
The contents of the images and PDFs you open are processed only on your computer.
- A file is read only when you opened it yourself: through the file dialog, by
dropping it on the window, by opening it with UFDI from Explorer, or because it sits in the same folder as a file you opened that way.
- Any other path is refused inside the program.
- File contents, file names and paths are never sent to a server.
3a. AI features (background removal, text recognition)
Background removal and text recognition run only on your computer, using AI models included in the installer. Your photos and the results are never uploaded and never used to train anything. The usage-statistics feature of the AI runtime (ONNX Runtime) is switched off in the program's code.
3b. Optional model download (high-quality background removal)
The high-quality background-removal model (about 170 MB) is not in the installer; you download it if and when you want it.
| Item | Detail |
|---|---|
| When | Only after you press "Get the high-quality model" and then "Download" in a dialog that shows the size, the source and what is sent. Never automatically |
| From | github.com (GitHub, Inc.) and the servers GitHub uses to deliver files |
| What is sent | One HTTPS request for the model file. As with any internet request, the server can see your computer's IP address and a fixed program label (UFDI/version (model download)); its own privacy policy governs its server logs |
| What is not sent | photos, file contents, file names or paths, device identifiers, usage history, account details |
| Verification | The file is used only if it matches the SHA-256 recorded in the program; otherwise it is deleted |
3c. Sponsored pictures in the program (off unless you switch them on)
| Item | Detail |
|---|---|
| Default | Off. Nothing is requested while it is off |
| How to switch on or off | Settings → Privacy → "Show sponsored pictures", or "Turn off" on the picture itself |
| When on | The home screen and the info panel each show one picture labelled "Sponsored". Every few hours the program asks the operator's server (section 3d) for one |
| What is sent | the place in the program (app-home or app-info) and the interface language. The server necessarily sees your IP address for the moment of the request, but does not store it |
| What is not sent | photos, file contents, file names or paths, usage figures, device identifiers |
| What comes back | an image (PNG, JPEG, WebP or GIF, checked by the program) and a link. No code from the server ever runs in the program |
| Clicking | opens the link in your web browser; from then on the advertiser's site and its own privacy policy apply |
3d. The website and its server
The website (ufdi.pages.dev) is a static site delivered by Cloudflare. A small server run by the operator (hosted by Railway, with a PostgreSQL database) counts page views and downloads and serves advertisements.
| What | How | Kept |
|---|---|---|
| Page views | the address of the page (without its query string), the language, the referring site's host name, country (from Cloudflare), operating-system family | aggregate counts for statistics, up to 2 years |
| Downloads | the same, plus which installer and which button | aggregate counts for statistics, up to 2 years |
| Unique visitors | a one-way hash of the IP address and browser label with a salt that is random, different every day, and deleted with the next day's first visit. The IP address itself is never stored, and the hash cannot be linked to you or across days | with the counts |
- No cookies are set, and nothing is stored in your browser for statistics.
- If your browser sends Do Not Track or Global Privacy Control, no page
view is recorded.
- Search engines and other bots are not counted.
Advertisements on the website. Some areas of the website may show advertisements. An advertisement runs in an isolated frame served from the operator's server, so it cannot read or change the page you are reading. If an advertisement comes from an advertising network, that network may set its own cookies or collect data according to its own privacy policy; you can block or delete those cookies in your browser. Before any advertising that uses personal data for targeting is shown to visitors in regions that require consent (such as the European Economic Area), the website will ask for that consent first.
4. What is stored on your computer
| Item | Location | Contents | How to remove |
|---|---|---|---|
| Settings | UFDI folder under the OS config directory (%APPDATA% on Windows), settings.json | theme, language, default zoom, thumbnail size, up to 20 recent file paths, whether sponsored pictures are on | "Clear recent list" in Settings, or delete the file |
| Library | same folder, library.json | stars, favourites and last PDF page per file, first-step checklist, monthly counts used for "time saved" | delete the file |
| Thumbnail cache | UFDI folder under the OS cache directory (%LOCALAPPDATA% on Windows) | preview images | delete the folder (entries older than 30 days are pruned automatically) |
| Logs | UFDI folder under the OS log directory | diagnostic messages | delete the files |
| Background-removal previews | cutouts folder inside the thumbnail cache | preview images of cutouts | delete the folder (cleared with the cache) |
| Sponsored pictures | promo folder inside the thumbnail cache | pictures shown while sponsored pictures are on | delete the folder |
| Optional models | models folder in the UFDI folder under the OS data directory (%APPDATA% on Windows) | the high-quality model you downloaded | delete the file |
All of this stays on your computer; the library and its counts are never sent anywhere. Release builds log warnings and errors only, and never log file contents.
5. Third parties and hosting
The program contains no advertising SDK, no analytics SDK and no crash-reporting service. The operator does not sell or provide your data to anyone. The services below process data only to deliver what you asked for:
| Service | Role | Data | Location |
|---|---|---|---|
| GitHub, Inc. | delivers installers and optional models | IP address and request, in its server logs | United States |
| Cloudflare, Inc. | delivers the website | IP address and request, in its server logs | worldwide network |
| Railway Corporation | hosts the operator's statistics and advertising server and its database | the counts in section 3d; the IP address only for the moment of a request | United States |
| Advertising networks (if used) | serve advertisements on the website | under their own privacy policies (section 3d) | varies |
Hosting data abroad (Railway) is necessary to run the server; the data stored there contains no IP addresses and no identifiers. You may object to this by not using the website's download button (use the GitHub releases page directly) and by blocking the website's requests; the program itself works without it.
6. Bundled software
UFDI never installs additional programs, toolbars or advertising software during installation or update.
7. Future features
Later phases may add document-analysis (AI) features. If such a feature needs to send data off your computer, the program will say so plainly before it runs and will act only after you explicitly agree. No such transfer will ever be the default.
8. Children
UFDI collects no personal data from anyone, including children. Sponsored pictures in the program are off unless switched on and are never chosen based on who is using the computer.
9. Your rights
Because the program collects nothing and the website's statistics hold no IP addresses or identifiers, there is no data about you to access, correct or delete on our side. The settings, cache and logs stored on your computer can be removed by you using the table above.
For data processed through an enquiry (section 2a) you may request access, correction, deletion or suspension of processing under Articles 35 to 37 of the Korean Personal Information Protection Act. Write to the address above and we will act without delay.
