Common questions
My satellite is out of propellant. Can I get more?
Not for real money — nothing in Celestrike is. Propellant is restored only by a servicing flight, which costs in-game credits and takes real transit time. A satellite with an empty tank is not dead: it still works perfectly well in the orbit it is in. It just cannot change that orbit any more until a flight reaches it.
I deleted the app and lost my progress.
Your save lives only on your device, so deleting the app deletes it. There is no cloud save in v1.0 and no copy on our side, which means we genuinely cannot recover it — we are sorry.
Does it work offline?
Yes, entirely. There is no server and nothing to connect to. Orbits are computed from the clock on your device, so time keeps passing whether you are online, offline or have the app closed — you will find the intel where the physics says it should be when you come back.
Time seems to have jumped forward while I was away.
That is correct behaviour. Nothing runs in the background; instead, positions are computed from elapsed time whenever you open the game. Two hours away is two hours of passes. Note the flip side: changing your device clock changes what the game computes.
Is there an Android version?
Yes — it has been on Google Play since 21 September 2026. It is the same game as on iPhone, and a campaign lives on the device it was played on.
Is there an iPad version?
Not in v1.0. The game ships portrait-only on iPhone. It will run on an iPad in compatibility mode, but the layout is not designed for that screen yet.
I found a bug, or the physics looks wrong.
Please tell us — the second one especially. Email support@celestrike.com with what you saw and what you expected. Orbital mechanics is counterintuitive often enough that a "bug" is sometimes the simulation being right, but we would much rather check than assume.
How do I delete my data?
Delete the app. That is the whole procedure — there is no account and no server-side copy. See the privacy policy for the detail.
