Privacy Policy
Odd Stack is a single-player game made by Jorge Marco Arráez ("we"). This policy explains what data the app handles and why. Odd Stack has no accounts, no sign-in and no servers of its own. It needs an internet connection to play, so ads can load.
Data stored on your device
Your game progress stays on your iPhone or iPad: best height, saved tower, discovered objects, achievements, settings, and the number of lives you have. We never receive it.
If you buy Remove Ads, a single "already granted" flag is saved in your own iCloud key-value storage so the bonus lives are not granted twice when you restore on another device. This is stored by Apple in your iCloud account and is not visible to us.
Purchases
In-app purchases (life packs and Remove Ads) are processed entirely by Apple. We never see your name, payment details or Apple Account. The app only checks the signed receipt Apple returns to unlock what you bought.
Advertising (Google AdMob)
Unless you buy Remove Ads, Odd Stack shows ads from Google AdMob: a banner below the playfield while you play, a full-screen ad after some falls, and optional rewarded ads you can choose to watch to continue. To serve and measure ads, Google may collect:
- Device identifiers such as the identifier for vendors (IDFV)
- Approximate location derived from your IP address
- Ad interaction data, such as ads shown and tapped
- Diagnostic data, such as crash and performance information from the ad SDK
Odd Stack requests non-personalized ads only. It does not ask for App Tracking Transparency permission, does not access the advertising identifier (IDFA), and does not track you across other companies' apps or websites. Ads are limited to content suitable for all ages.
In the European Economic Area, the UK, Switzerland and US states with privacy laws, the app asks for your consent with Google's consent form before any ad is requested. You can change your choice anytime in Settings > Privacy choices inside the app.
Google's use of this data is described in How Google uses information from sites or apps that use its services and the Google Privacy Policy.
Analytics (Google Analytics for Firebase)
To learn which game settings people enjoy most, and to compare versions of them, Odd Stack uses Google Analytics for Firebase and Firebase Remote Config. They receive anonymous gameplay events:
- When a run starts and ends, the height reached and the number of objects stacked
- Whether you continued a run, chose a power-up, shared the app or completed an in-app purchase (product name only)
- An app-instance identifier, your approximate location derived from your IP address, and basic device information
This data is not linked to your identity and is not used for tracking or personalized ads. In the European Economic Area, the UK and Switzerland, analytics only stores data on your device if you agree in Google's consent form; you can change this in Settings > Privacy choices. Google's use of this data is described in the Firebase privacy information.
Sharing the app
If you choose to share Odd Stack with a friend, the iOS share sheet sends a link to the App Store. We do not see who you share it with; the app only counts completed shares on your device for the extra life.
What we do not do
- We do not collect your name, email, contacts, photos or precise location.
- We do not sell personal data.
- We do not use crash-reporting services, and we do not run analytics servers of our own.
Children
Odd Stack is a general-audience game and is not directed at children under 13. We do not knowingly collect personal information from children.
Your rights
Deleting the app removes all game data from your device. You can withdraw ad consent in Settings > Privacy choices, and reset or limit ad data in your device's privacy settings. For any privacy question or request, email jmararr1@gmail.com.
Changes
If this policy changes, we will update this page and its effective date.
