Who we are
Our Solar System (3dsolarsystem.online) and its apps (the Our Solar System app for Apple Vision Pro, iPhone, iPad and Mac, the 3D Solar System app for Meta Quest, the Qmax desktop app and the screensaver for Mac, Windows and Linux) are made by Polyxmedia. Write to hello@polyxmedia.com about anything on this page.
The short version
The 3D viewer works without an account. We keep what we need to run accounts, purchases, reminders, classes and support, and we measure how the website is used (with cookies in the UK, the EEA and Switzerland only if you agree), never on the pages pupils use. We do not sell personal data, and there are no ads. Some sky event and planet pages link to telescopes, binoculars and eclipse glasses at Agena AstroProducts, and we earn a commission on what is bought through those links.
What we collect, and why
An account, if you make one. Your email address, a name if you give one, and your password (stored only as a one-way hash) or the sign-in codes we email you. We also keep when you joined and were last seen, the country your connection comes from (from our host's network, not your location), where you signed up (for example the game or a reminder) and whether you want our occasional news email. For each signed-in device we keep its IP address and browser name, so you stay signed in and can sign other devices out.
Game saves you keep in the cloud: your Qmax career and rocket designs, with a short history so you can roll back.
Purchases are taken by Stripe. We receive your email address, country, the amount and the tax; your card details go to Stripe and never reach us. The licence we issue is tied to the purchase. When something you bought gets an update we email you what is new in it, and keep a record of that email; the link at the bottom stops them for that product.
Sky reminders and launch notices: the events you asked to hear about, and when we emailed you.
ISS pass alerts, if you turn them on: the place you picked, rounded to about 10 km, its name, your time zone, and when we last emailed you. We use them only to work out when the space station passes over and to send you the times. Your browser's location is used only when you press Use my location on the ISS page, to show passes there; it is sent to us only if you then turn alerts on, and then only rounded.
Classes, if you teach: the classes you make, the lessons you set them and the pupils in them (see Classes and pupils below).
Support messages you send us, and our replies.
Usage statistics through Google Analytics, on this website: pages viewed, and events such as which features are used, when a product page is seen, when a checkout starts, when a purchase completes (Stripe’s reference for the checkout, the product and the amount; never your name, email or card), downloads, a licence unlocking the game, VR or AR starting in a headset, and a click on one of the gear links (which link, on which page). Google processes your IP address to do it. Its cookies, and your choice about them, are under Cookies and analytics below.
Bot protection: when an account is created, Vercel BotID checks that a person is behind it.
On your device: your settings, the game career, licences and an anonymous id (used to switch features on for testing) are kept in your browser's storage and never leave it unless you sign in and sync.
Cookies and analytics
Google Analytics measures visits to this website. Where it is allowed to, it keeps two cookies in your browser, _ga and _ga_HCFE53G4HN, for up to two years, so a returning visit can be told from a new one. It runs only on 3dsolarsystem.online: the screensaver, the live wallpapers, the Qmax desktop app and the App Store apps carry none, and neither do the pages pupils use.
In the UK, the European Economic Area and Switzerland it starts switched off. Until you agree, Google Analytics sets and reads no cookies. Each page still tells Google it was viewed, with no cookie or identifier from your device, and Google uses those signals to estimate visitor numbers (Google calls this Consent Mode). When your device’s time zone is in Europe we ask once, at the bottom of the screen. Accept turns the cookies on in this browser. Decline keeps them off and deletes any Google Analytics cookies already set.
Everywhere else Google Analytics uses its cookies from your first page, and you can turn them off below at any time.
Advertising storage stays off whatever you choose: there are no ads here. Your choice is kept in this browser’s storage (ss.consent) and applies on every page of the site until you change it or clear your browser’s data. Ad blockers and browsers that block Google Analytics stop it too.
Classes and pupils
Teachers can make a class for their pupils on the teachers’ page. A teacher has an ordinary account and accepts our school terms once before making a class. The school decides how its pupils’ class data is used, and we keep it only to run the class: it is never used for advertising or analytics and never sold.
Pupils do not make accounts, and they are never asked for an email address, an age or where they live. For each pupil we keep the first name or nickname they or their teacher chose (40 characters at most; email and web addresses are refused), a four-character login code for carrying on from another device, and, for each device they join on, a random token stored only as a one-way hash, with when it was last used. We also keep how far they got in each lesson their teacher set, their answers to its questions, whether each answer was right and how many tries it took.
The teacher sees the nicknames, login codes, progress and answers, and can download them as a spreadsheet. Anyone with the class code sees the list of nicknames, so a pupil can pick theirs when signing back in.
The class page, the teachers’ class pages and lessons opened from a class load no Google Analytics. A pupil’s device keeps its token, and any answers waiting for a connection, in the browser’s storage; leaving the class on that device removes them.
A class and everything in it is deleted 13 months after it was made, or sooner when the teacher deletes it, removes a pupil or deletes their own account. Joining closes by itself 14 days after the teacher last changed the class, so an old class code lets nobody new in.
A parent or pupil who wants a pupil’s class data changed or removed can ask the teacher, who can rename or remove the pupil at once, or write to us at the address above.
The apps
The Our Solar System app on Apple Vision Pro, iPhone, iPad and Mac collects no data: no account, no analytics, no tracking and no advertising. Positions are computed on the device and your saves stay on it.
When it is online, the iPhone, iPad and Mac app downloads sharper imagery of the Earth, Moon and clouds and the latest satellite positions, from our servers, NASA (GIBS), EOX and CelesTrak. Those requests carry only what any download does, such as your IP address, and we do not keep them or link them to you.
The 3D Solar System app for Meta Quest is bought on the Meta Horizon Store: Meta takes the payment and tells us nothing about you, and the app has no account, no sign-in and no in-app purchases. It is this website in a headset, so it loads the same imagery and positions as the viewer and measures use with Google Analytics like the website, each event marked as coming from the Quest app. It never asks the cookie question, so in the UK, the EEA and Switzerland it sets no analytics cookies unless you accepted them on this website on the same headset. It reads the headset's position and the controllers or hands only to draw the view and answer them, on the headset; none of that is stored or sent anywhere.
Who handles it for us
Vercel hosts the site and its servers (United States). Neon stores the account database (United States). Stripe takes payments on the website, Meta for the Quest app. Resend sends our email. Google provides Analytics and the fonts on our pages. A gear link takes you to agenaastro.com with our affiliate code on it; Agena and its affiliate platform, Refersion, then set their own cookies there so a purchase is credited to us, under their own privacy policies. They tell us a purchase was made and our commission, and we never receive your name, address or payment details from them.
The Earth imagery is requested by your browser from NASA (GIBS) and EOX, and they see your IP address as any website you load from would. Satellite positions reach you through our server from CelesTrak.
How long we keep it
Account data stays until you delete the account. Purchase records are kept as long as tax and accounting law requires. Reminders are deleted a week after their event. An ISS alert is kept until you stop it, from the email, the ISS page or your account. A class is deleted 13 months after it was made, or sooner by its teacher. Google Analytics keeps event data for up to 14 months.
Your choices and rights
From your account you can download everything we keep about you as a file (a teacher’s file includes their classes), change your details, turn the news email off, and delete the account. Every reminder, ISS alert and update email has a one-click unsubscribe.
Wherever you live you can ask us for a copy of your data, to correct it or to delete it, at the address above. In the UK and the EU you also have the right to restrict or object to how we use it, to take it elsewhere, and to complain to your data protection authority (in the UK, the Information Commissioner's Office). We handle account, purchase and reminder data to provide what you asked for, security and bot checks in our legitimate interest, and the news email and, in the UK, the EEA and Switzerland, analytics cookies only with your agreement. Cookie settings, under Cookies and analytics above, changes that choice at any time.
Children
The viewer is for everyone. Accounts are for people aged 13 and over.
Younger pupils take part in lessons through their teacher’s class, which asks for no account, no email address and no age (see Classes and pupils above). We do not knowingly collect personal data from children under 13 in any other way. If you think a child under 13 has made an account, write to us and we will delete it.
