Privacy policy
Last updated: November 5, 2026
This policy covers the apps and games made by Strobi LLC (“Strobi”, “we”, “us”): Tilery, RGB, Drift (formerly Transition), Colorize and Trace Race on iOS, Android and the web, Foldwing on iOS and Android, Trace Race on Reddit, Stampede on iOS, Android and the web, and this website, strobi.dev. EosLog, our field service software, has its own policy at eoslog.com/privacy.
What we collect
Nothing, in the apps themselves. Tilery, RGB, Drift, Colorize and Trace Race have no sign-in, no ads, no analytics and no crash reporting SDKs, and they don't send your data to us or to anyone else. They work without an internet connection.
What stays on your device
- Tilery saves your level stars, best scores, streaks, chosen theme and sound settings.
- RGB saves your saved colors, their names and your last color mode. If you use the live camera picker or pick a color from a photo, the picture is read on your device to find the color; it is never saved, recorded or sent anywhere.
- Drift saves your clock face, colors and night mode settings.
- Colorize saves your high scores, sound setting and button-press count.
- Trace Race saves your daily results, streak, practice best scores, sound settings and the path you traced in today's game.
This data never leaves your device. Uninstalling the app, or clearing site data in your browser for the web versions, deletes it. We can't see it, recover it or move it for you.
Some apps keep the screen awake or use vibration for haptic feedback, which you can turn off in their settings. These use device features only and collect nothing.
Foldwing
Foldwing scans, edits and signs documents on your phone. Your scans, PDFs and signatures are stored only on your device, and camera images are processed on the device. The app has no sign-in, no ads, no analytics and no crash reporting SDKs.
To keep track of fax credits, the app creates a random device ID when you first open it and stores it on our server with your device type (iPhone, Android or web). Credit purchases, fax charges and refunds are recorded against that ID. Purchases are made through Apple or Google and reported to us through RevenueCat, which tells us which credit pack was bought and the store transaction ID, not your name or payment details.
When you send a fax, the PDF, the fax number and any recipient name you type are sent to our server and to Telnyx, our fax provider, only to deliver it. We delete our copy of the PDF once the fax is delivered or fails, and in any case within two days. We keep a record of each fax (the number, recipient name, page count, status and time) so you can see your history and so failed faxes can be refunded.
Our server runs on Cloudflare. It uses your IP address briefly to limit how many new devices can be set up from one network, and doesn't store it. This data isn't sold, shared for advertising or used to track you.
Trace Race on Reddit
The Reddit version of Trace Race runs inside Reddit, on Reddit's developer platform. To run each community's daily leaderboards and streaks, it saves your Reddit username and user ID with your results in that community: your score, time, accuracy and which shape you got each day, plus the path you traced, which is kept for four days so you can watch the replay. This data is stored on Reddit's servers. Other players can see your username and score on the leaderboard. It isn't sold, shared with anyone else or used for ads.
If you tap “Comment your result”, the app posts your result as a comment from your account, and only after you allow it. Sound and vibration settings and practice best scores stay on your device. Reddit's own privacy policy also applies when you use Reddit.
Stampede
To help us balance Stampede, each run you play in the iPhone app, the Android app or on the web is saved to a database on Cloudflare: game stats like how long you survived, the waves, your gold, what you built and where, the monsters on the board at a few moments, and whether you played on a touch screen. Runs don't include your name, an account, your IP address or anything else that identifies you. If you send feedback from the game, your star rating and comment are saved too, plus a name only if you type one.
This data is used only to improve the game. It isn't sold, shared with anyone else or used for ads, and it isn't linked to you or your device. The game needs no account and has no ads, analytics SDKs or tracking. Your progress, settings and any name you type are also kept on your device (or in your browser on the web) so the game remembers them.
This website
strobi.dev doesn't set cookies or use ad trackers. It is hosted by Cloudflare, which processes standard technical request data (such as IP address, browser type and the page requested) to deliver and protect the site, and counts page views with Cloudflare Web Analytics, which doesn't use cookies or track you across sites. See Cloudflare's privacy policy. The theme switch remembers your choice in your browser's local storage.
App stores and game portals
When you download our apps from the Apple App Store or Google Play, or play our games on a portal such as CrazyGames or Reddit, that store or portal may collect information under its own privacy policy. In Foldwing, purchases also pass through RevenueCat and faxes through Telnyx, each under its own privacy policy. We don't receive personal information about you from them; we may see aggregated, anonymous statistics such as download counts.
If you email us, we receive your email address and whatever you include in your message. We use it only to reply and to improve our apps, and we don't sell or share it.
Children
Our apps are suitable for all ages and don't knowingly collect personal information from anyone, including children under 13. Trace Race on Reddit is only for people with a Reddit account, and Reddit requires users to be at least 13.
Your choices and rights
Most of our apps don't collect personal information, so there is usually nothing for us to access, correct or delete. To remove your local data, uninstall the app or clear your browser's site data. To have your Foldwing credit and fax records, your Trace Race on Reddit data or your Stampede feedback removed, or anything you've sent us by email, write to us and we'll delete it. For Foldwing, tell us roughly when you sent a fax and the number you sent it to so we can find your records.
Changes
If we change how our apps handle data, we'll update this page and the date above before the change takes effect.
