Privacy

Our apps keep your data on your device. Here's the whole policy, in plain language.

The short version

Our apps keep your data on your device. We don't run accounts, we don't collect analytics, we don't use tracking or advertising SDKs, and nothing you create in an app is sent to us or to anyone else. Infinite Art Gallery is the one app that talks to a server of ours, and only to fetch free photography by subject; what it records is set out below.

Apart from emails you send us, the only personal detail we hold is your email address, and only if you join our mailing list.

What our apps store

Everything you create in an Altroad Studio app, such as notes, photos, settings, and preferences, is stored locally on your device. If you delete the app, that data is deleted with it.

Cabernet, our wine tasting notebook, keeps your tasting notes, cellar entries, and label photos on your device. Photos you take never leave your phone. The camera and photo library are used only when you choose to add a label photo, and only for that photo.

Flipspark, our prompt-card deck for music producers, keeps your custom prompts and draw history on your device.

Black Hole Sandbox, our black hole simulator, keeps your settings, presets, and preset thumbnails on your device. The camera is used only in augmented reality mode, to place the black hole in your room, and nothing it sees is recorded or stored. If you pick a photo for the accretion disc, the app receives only that photo, and it stays on your device, including when you save it into a preset.

Infinite Art Gallery, our endless walkable gallery, keeps your settings, presets, and saved tags on your device. When you choose an album, your photos are read from your photo library and hung on the walls as you walk; they are never uploaded, and the app only reads albums you pick. The free photography that fills the gallery by default comes from Pexels, and is fetched through a server we run.

Fly Brain, our 3D fruit fly, keeps your settings on your device. It uses the camera, microphone, and motion sensors so the fly can react to what it sees, hears, and feels, and in augmented reality mode the camera places the fly in your room. All of it is processed on your phone as it happens: nothing the camera or microphone picks up is recorded, stored, or sent anywhere. The camera and microphone are optional, and without them the fly still reacts to touch and motion.

Planet Crash Sandbox, our planet collision sandbox, keeps your settings and tuning on your device. The camera is used only in augmented reality mode, to place the solar system on your table, and nothing it sees is recorded or stored. A collision you compute in cinematic mode is held in temporary storage on your phone while you watch it, and is deleted when you leave it.

What we receive

If you email us feedback from inside an app, we receive your email address and whatever you write, along with the app version and device model the app includes so we can reproduce bugs. We use that only to reply to you and to fix problems, and we never share it.

Infinite Art Gallery asks our server for photographs by subject, such as nature or cityscape. We record the subject asked for, the page number, and the time, so we can keep the app inside the Pexels API's monthly quota. Nothing identifies you: no account, no device identifier, and no IP address is stored alongside it, so a recorded subject cannot be traced back to a person or a device.

Apple provides developers with aggregated, anonymised App Store statistics such as download counts and crash reports. These are governed by Apple's own privacy policy and the choices you make in your device settings.

Our mailing list

If you sign up for news on this site, we keep your email address, which list you joined, and when and where you signed up. We use it only to email you about our apps and games. The address is stored with Supabase, and our emails are sent through Resend; neither uses it for anything else, and we never sell it or share it with anyone else.

Every email has an unsubscribe link, or you can just reply. Once you unsubscribe, we keep your address only so we never email you by mistake. If you'd like it deleted entirely, email support@altroadstudio.com and we will.

If you signed up for Flipspark news or bought a deck on the original Flipspark website, your details were moved here when that site closed.

This website

altroadstudio.com sets no cookies. It uses Vercel Web Analytics, which counts page visits in aggregate, without cookies and without building a profile of you.

It, and our browser games at holdthehorde.io and badaboomtaxi.io, also use PostHog to understand how visitors find and move around them: which pages they visit, which site sent them, and which links and buttons they press. PostHog keeps a random ID in your browser's local storage so one visit's pages can be linked together. It is not tied to your name, email or account, it does not record your screen, and we never sell it or use it for advertising. Clearing your browser's site data removes it.

Changes and contact

If a future app ever needs to handle data differently, this page will say so plainly before that app ships, and the change will never apply retroactively to data you already have.

Questions about any of this: support@altroadstudio.com.
