Stack Drop Tower ("Stack Drop" on your home screen) is a single-player game made by Coderflight. There are no accounts and no sign-in. We do not operate a server for the game and we never receive your game data.
In short: there are no accounts and nothing you do in the game is sent to us. Your progress stays on your device. The game shows ads through Google AdMob, which collects some data under Google's own policy, and you decide whether your advertising identifier may be used.
1. What stays on your device
The game saves your progress locally, using the operating system's standard app storage. That is the whole list:
- your highest unlocked level, your best block count per level and your best Endless run;
- the coins you have earned;
- blocks stacked and perfect drops over your lifetime, used to award block finishes;
- the block finishes you own, and the one equipped;
- your daily bonus streak, and the day it was last claimed;
- your sound, music, vibration and reduced motion settings;
- whether Remove Ads was purchased.
None of this identifies you, none of it leaves your device, and none of it is readable by us. Deleting the app deletes all of it.
2. Advertising (Google AdMob)
Stack Drop shows ads through Google AdMob. Ads are how the game is funded.
AdMob is a third party and collects data itself, under Google's own privacy policy rather than ours. Depending on your choices, it may process your device's advertising identifier, your IP address, general device information and how you interacted with an ad. Google explains this in How Google uses information from sites or apps that use its services.
Rewarded ads are always your choice: for example, to continue a run once after a loss, or to double a reward. Breaks between runs appear after a few finished runs, never during play.
3. Tracking: your choice
On iOS, the game asks through Apple's App Tracking Transparency prompt whether it may use your device's advertising identifier. If you decline, it is not used. You can change this at any time in iOS Settings › Privacy & Security › Tracking. The game plays exactly the same either way.
4. Consent
Where data protection law requires it, for example in the European Economic Area and the United Kingdom, the game shows Google's consent form before any ad loads and before the advertising SDK starts. You can reopen it at any time from Settings › Privacy settings in the game and change your answer, even after buying Remove Ads.
5. Remove Ads
The optional Remove Ads purchase stops the ad breaks between runs. Rewarded ads remain available, only if you choose to watch one.
It is a one-off purchase handled entirely by Apple. Apple tells the game only whether the purchase is owned. We never see your payment details, and we do not receive your Apple Account information.
6. Children
Stack Drop is not directed at children, and we do not knowingly collect personal information from them.
7. Your rights
Because we hold no data about you, there is nothing for us to export or delete. To remove everything the game has stored, delete the app. For data held by Google as an advertising provider, use the consent and tracking controls above, or contact Google directly. You can always contact us for help.
8. Changes to this policy
If this policy changes, the date at the top of this page changes with it.
