1. The short version
There is no YendleBox account and no YendleBox server holding your library. Your games, saves, playtime and settings sit in one file on your own disk and are never uploaded by us.
No analytics, no crash reporting, no telemetry. Out of the box the application makes no network request you did not configure.
The only things below that involve the internet are ones you opt into: pre-registration, cloud saves, Retro Lobby, and the optional metadata and achievement services.
2. Who this covers
This policy applies to the YendleBox desktop application, the Pocket YendleBox Android application, the yendlebox.com website, and the Retro Lobby rendezvous service. The data controller is the YendleBox Development Team.
3. What stays on your device
YendleBox stores your library, play history, save-file backups, progress readings, screenshots, settings and any API keys you enter on your own computer, in a single database file beside the application and its backups folder. None of it is transmitted to us, because there is nowhere for it to go.
Your game files and save files are read, never written to. Nothing in your ROM folders is moved, renamed or modified, and save states are out of scope entirely.
4. This website
The site is static. It sets no cookies, runs no analytics, and has no tracking pixels, advertising tags or embedded social widgets. Fonts and scripts are served from this site, so loading a page does not cause your browser to contact any third party.
The site is served by Cloudflare, whose infrastructure may keep standard connection logs under Cloudflare’s own privacy policy. We do not receive, store or analyse those logs.
5. Pre-registration
If you pre-register, the email address you enter is stored in Cloudflare key–value storage and used for exactly one thing: a single email containing the download link when YendleBox launches. It is not shared, not sold, and not used for a newsletter. The list is deleted once that email has been sent. Ask us sooner and we will remove you.
6. Optional services
YendleBox can fetch artwork, metadata and achievements from outside services. Every one is off until you enable it, and when you do, your computer contacts that service directly — the request does not pass through us, and any key you supply is stored on your machine and sent only to the service it belongs to.
Depending on what you turn on these may include ScreenScraper, IGDB, SteamGridDB, EmuMovies, TMDB, Hasheous, RetroAchievements, Steam, Exophase, Open‑Meteo, GitHub, Discord, ElevenLabs and YouTube. Each has its own privacy policy, which governs what it does with your request. Settings → Connections shows what is configured, and you can disconnect any of them at any time.
7. Google Drive
Cloud saves are off by default. If you enable them, YendleBox uses your own Google Drive with the drive.file scope, which allows an application to see and manage only files it created itself. It cannot read anything else in your Drive. Nothing is uploaded to us, and the sync client has no delete capability at all.
YendleBox’s use of information received from Google APIs adheres to the Google API Services User Data Policy, including its Limited Use requirements. You can revoke access at any time from your Google Account permissions page.
8. Retro Lobby
Retro Lobby lets someone join a game from their browser. Playing on your own local network involves no outside service. If you invite someone over the internet, a rendezvous service introduces the two browsers, and to do that it necessarily handles the lobby code and seat assignments, any display name typed, the game title, timing, and — because the connection handshake contains network addresses — the IP addresses of everyone connecting, including yours.
Where a direct connection cannot be made, encrypted traffic is carried by a relay. Credentials are short-lived and records are ephemeral: they exist while a lobby is open and are discarded when it closes. Your library, saves and the game itself never leave your PC. Retro Lobby can be switched off entirely.
9. Your home network
YendleBox serves your library to your local network and it has no password. By default anyone on your Wi-Fi can browse your library and launch games on your PC. This is deliberate — the phone remote, marquee, Retro Lobby and Android app all need it.
Settings → Network access → Only this PC shuts that off. Kiosk lock adds a PIN to Settings. Do not forward YendleBox to the public internet.
10. Children
YendleBox is not directed at children and we do not knowingly collect information about them. Because there are no accounts, we do not gather personal information from anyone through the application itself.
11. Seeing and deleting your data
Your data is on your own machine, so you already control it. Open the database file beside the application to see everything YendleBox knows. Uninstall it and delete its folder to remove all of it — nothing is left on any server, because there was never a copy on one. Revoke Drive access in your Google Account to stop cloud sync, and remove any service key in Settings → Connections.
12. Your rights
Where we do process personal data — realistically the pre-registration email and the lobby handling above — we rely on your consent, and on our legitimate interest in operating the feature you asked to use. Depending on where you live you may have the right to request a copy of your data, or its correction or erasure, and to complain to your data-protection regulator.
We do not sell personal information and we do not share it for advertising or profiling.
13. Changes
If this policy changes, the date at the top changes with it. Where a change materially affects what leaves your machine, it will be noted in the release notes for the version that introduces it.
