Something wrong with a run?

Neorun has no account and no server, so there is nothing for me to look up on my side. What you tell me in an email is all the information that exists — please be specific.

Before you write

My multiplier collapsed and I did not touch anything.

That is the rule, not a bug: the multiplier decays after 3.2s without a new near miss. It is the one thing in the game you cannot hold by playing safe.

I paid to remove ads and they came back.

Open Settings inside the app and tap Restore Purchases, then relaunch. Check you are signed in to the same Apple Account that made the purchase — a different account on the same device will not see it. If ads are still there afterwards, email me the purchase date and I will look at the receipt with you.

My best score and my prisms are gone.

They live on the device, not on a server. They are included in an encrypted iPhone backup, so restoring a backup brings them back; deleting the app deletes them permanently. There is no account, so they do not sync between two phones being used at once.

The Daily Challenge looks different from my friend's.

The track is generated from the calendar date in your device's time zone. If you are on opposite sides of a date line you can genuinely be on different days. Compare the date shown on the Daily card, not the clock.

A row felt impossible.

Every row is generated with one clear lane no more than one lane away from you, so it should never be. If you are sure you saw one, send a screen recording — that is a generator bug and I want it.

The game stutters or the fans spin up.

Turn the particle trail off in the shop and close other apps. If it only happens in Overdrive, tell me which world you were in — the grade change is the heaviest moment in the game.

How do I delete my data?

Delete the app. Everything it stored goes with it, because there is no copy anywhere else. See the privacy policy.

Refunds

Purchases go through Apple, not through me.

I cannot issue a refund even when I agree with you. Request one at reportaproblem.apple.com — and tell me what went wrong anyway, so it gets fixed.
