Progress is stored on your device, not on our servers, so it can't be recovered remotely. Deleting the app deletes the save with it. Restoring a device from an iCloud backup that included the game will normally bring the save back.
Yes — Settings → Reset Progress. It clears level stars, Scrap, Cores, upgrades and unlocked hulls, and puts you back at Sector 1. Your settings and any purchases are kept. It cannot be undone.
Rewards are granted when the ad reports that it finished. If you close an ad early, no reward is given — that's the ad network's rule, not ours. If an ad completed and nothing arrived, email us with the approximate time and what you were doing.
No. There are no banners and no ads between levels. The only ads in the game are ones you opt into — reviving after a death, doubling a run's payout, or an extra crate — and the game is fully completable without ever watching one.
No. Declining Apple's tracking prompt does not restrict any part of the game, and every rewarded ad still works. You may simply see less relevant ads.
Upgrades compound quickly — Hull HP and Shield in particular. If a level keeps stopping you, replaying an earlier one for Scrap and buying a couple of levels of an upgrade track usually moves things along faster than retrying.
Settings → Share Analytics. It's off until you turn it on, and switching it off also asks our analytics provider to delete what was collected from your device.
