Fast Rocket
Fast Rocket Privacy Policy
Short version: Fast Rocket is an offline, single-player game. It does not collect, send or share any personal data. There are no accounts, no ads, no advertising IDs and no tracking. Your progress is saved only on your own device.
The game can optionally send anonymous diagnostics (device details, performance numbers and crash reports) to our own server, only if you say yes. It is off by default, and nothing is sent before you agree. You can turn it off, or reset its random ID, at any time. Details are under Optional diagnostics.
Who we are
Fast Rocket is made by Binary Helix ("we", "us"). This policy explains what the game does with information about you, which is very little.
What the game stores, and where
To remember your progress, the game saves a small amount of data on your device: in your browser's local storage on the web, in the app's private storage on Android and iOS, and in the app's own data folder on Windows and macOS. This includes:
- your settings (for example volume, controls, accessibility options and language),
- your rocket designs and saved flights,
- your progress: Flight School lessons, stars, rank, achievements, personal bests and daily-challenge streaks,
- your choice about diagnostics and, only if you said yes, a random diagnostics ID and a small queue of diagnostics waiting to be sent.
Apart from the optional diagnostics described below, this data stays on your device. We cannot see it, and it contains no name, email address, contact list, location, photo or device identifier.
What we do not collect
- No accounts or sign-in.
- No third-party analytics, crash-reporting or tracking tools, and no tracking across apps or websites.
- No diagnostics of any kind unless you opt in (see Optional diagnostics).
- No advertising and no advertising identifiers.
- No in-app purchases.
- No location, contacts, camera, microphone or file access.
- No chat, multiplayer, leaderboards or cloud saves.
All of the game's art, music, sound and voice lines are included in the game itself; nothing is streamed from us while you play.
Optional diagnostics
Once, in the Space Center (after your first flight, or after a couple of minutes there; never during a flight or a Flight School step), the game asks whether you would like to help improve it by sharing anonymous diagnostics. Until you answer yes, nothing is stored or sent. If you say yes, the game sends the following to our server at binaryhelix.dev over HTTPS, and nothing else:
- Device and game: the game version and platform (web, Android, iOS or desktop), operating system and version, device model, browser name and version, a cleaned copy of the browser's user-agent text, screen size and pixel density, orientation, number of processor cores, memory class, whether there is a touch screen, the graphics card (GPU) name and maximum texture size, and the graphics quality the game chose for your device and your graphics settings.
- Performance: averages over about 90 seconds for each screen (menu, Space Center, builder, flight): frames per second, frame times, draw calls, triangles, script time per frame, long tasks, and memory in use (the browser's JavaScript heap where it reports one, and decoded audio). Also how long the game took to start, how long each session lasted, and how long you spent on each screen.
- Flight School: the lesson and step you were on, how many seconds you spent on it, how far the hints went (0 to 3), and how the step ended (finished, skipped, left or failed).
- Errors and crashes: error messages and technical stack traces, on which screen and how often, the last 20 or so breadcrumbs (screen changes, lesson steps, quality changes), and whether the graphics context was lost. If the previous session seems to have ended without a clean shutdown (it could be a crash, running out of memory, or the system or you closing the app), the next session reports its last screen, frame rate, memory and lesson step. URLs, file paths, e-mail-like text and long tokens are removed before anything is sent.
- A random install ID and a random session ID, so that one device's numbers can be told apart from another's.
What is not included: your name, email address, any account, anything you type, your location, contacts, files, photos, microphone or camera, advertising identifiers, cookies, your saved rockets, your progress and achievements.
The random ID. The game makes it on your device when you opt in. It is not your name, email, advertising ID or hardware ID, it is not derived from your device, and we cannot tie it to you. You can replace it at any time with "Reset diagnostics ID"; after that, data already sent under the old ID can no longer be connected to your device by anyone, including us.
Who receives it. Only us, on our own server. No third party receives it: no analytics, crash-reporting, advertising or hosting-of-logs company. We do not sell it or share it.
Your IP address. The diagnostics collector stores no IP address and no User-Agent. It holds the connecting address only in memory, to limit abuse, and never writes it to disk or to its logs. The diagnostics address (/fastrocket/api/t) is configured to be excluded from the web server's access log, so the addresses of diagnostic uploads are not written there either. The web server's separate error log, which records faults only, could in rare cases show the address of a failed connection.
How long we keep it. At most 90 days, then it is deleted automatically. The store is also capped in size (per day and in total); if a cap is reached, older data is deleted first and new uploads may be refused until there is room.
Turning it off or resetting it. In the Workshop, open General and use "Share diagnostics" to switch it off, or "Reset diagnostics ID" for a new random ID. During a flight, the pause menu has the same two controls under Settings. Turning it off deletes the queue waiting on your device and the ID, and stops sending immediately.
Asking us to delete it. Email linh@ai-hacker.com with the diagnostics ID shown in Workshop > About, and we will delete everything stored under that ID. Without the ID we cannot tell which data is yours.
Permissions on Android
The Android app asks for two permissions. INTERNET is declared because the app's built-in web view needs it to display the game that is packaged inside the app. The game itself makes no network requests, except for sending the optional diagnostics described above if, and only if, you turned them on. VIBRATE lets the game give haptic feedback (for example on staging and landing). It never requests any other permission.
Sharing a rocket or a flight report
If the game offers to share a rocket code or a flight-report picture, it creates that text or image on your device. Nothing is sent anywhere unless you choose to copy it or share it with another app yourself, and then it is subject to that app's own policy.
The web version
If you play in a web browser at binaryhelix.dev/fastrocket or linh.com/fastrocket, your browser downloads the game's files from our web server. The game then saves your progress in your browser's local storage and keeps an offline copy of its own files in your browser's cache (through a service worker) so it can start faster and work without a connection. Like almost every web server, ours keeps standard access logs (IP address, time, requested file, browser type) for security and troubleshooting. Uploads of the optional diagnostics (the /fastrocket/api/t address) are excluded from that log. We do not use these logs to identify or track players, we do not combine them with other data, and we do not sell or share them. The web version sets no cookies and loads no third-party scripts, fonts or images.
App stores and backups
Google Play and the Apple App Store handle the download of the app under their own privacy policies. We receive only the standard, aggregated statistics those stores provide to all developers; they do not identify you to us. If you have device backup turned on (Android backup, iCloud), your device may include the game's save data in your own personal backup. We have no access to those backups.
Children
Fast Rocket is aimed at players aged 13 and over. The game collects no personal information from anyone. The optional diagnostics are anonymous and off by default, and the consent card is not designed for children. If you believe a child under 13 has turned diagnostics on, email us with the diagnostics ID and we will delete that data.
Deleting your data
All game data lives on your device. To delete it, uninstall the app, or clear the app's storage in your device settings. On the web, clear the site data for binaryhelix.dev or linh.com (whichever you played on) in your browser. We hold no name, email address or account for you, so there is normally nothing of yours to delete on our side. The one exception is the optional diagnostics: if you turned them on, use the switch or the reset described under Optional diagnostics on your device, and note that what we received is kept at most 90 days and is tied only to the random ID. To have it deleted sooner, email us with the diagnostics ID shown in Workshop > About.
Changes to this policy
If a future version of the game changes how it handles data, we will update this page and the date above before that version is released, and we will update the app's store data-safety information to match.
