In short. Stackborne has no accounts and never asks for your name, email, photos, contacts or location. Your game progress stays on your device. The app shows ads through Google AdMob and sells one optional purchase (the "No Ads" pack) through Google Play and RevenueCat, and sends crash reports to Sentry so we can fix bugs; those services receive the limited technical data described below. We never sell your data.
1. Who is responsible
Stackborne is published by Novaku, an independent developer established in Spain, which is the data controller under Regulation (EU) 2016/679 (GDPR) and Spanish Organic Law 3/2018 (LOPDGDD).
Contact for privacy matters: novakuapp@gmail.com (subject "Privacy – Stackborne").
2. What stays on your device
Your records (the Ascent and the Classic mode), the zones you have reached, whether you own the No Ads pack, and your settings (sound, music, vibration, reduce motion) are stored only on your device. They are not sent to us and are deleted when you uninstall the app or clear its data.
3. Data processed by third-party services
| Service | Data | Purpose | Legal basis |

The data above is not linked to your identity: Stackborne has no accounts and we cannot identify you from it.
4. Your choices about ads
- In the EEA, the UK and Switzerland, a consent form is shown on first launch. You can change your choice at any time in Settings → Privacy options inside the game.
- You can reset or delete your advertising ID in your device's Android settings (Google → Ads).
- The optional No Ads pack removes the banner and the interstitial ads, and grants the "second chance" without a video. Videos with a reward (the second chance) are always optional.
5. Sharing
We do not sell or rent personal data. Data is only processed by the providers listed in section 3. The game has no sharing, chat or social features.
6. International transfers
Google and RevenueCat may process data in the United States, and Sentry's support staff may access EU-stored reports from the United States. These transfers rely on the EU–US Data Privacy Framework and/or the European Commission's Standard Contractual Clauses.
7. Retention
- On-device game data: until you uninstall the app or clear its data.
- AdMob data: according to Google's retention periods.
- Purchase records at RevenueCat: while needed to keep your purchase active and restorable, and to comply with accounting and tax obligations.
- Crash reports at Sentry: deleted automatically after at most 90 days.
8. Your rights
Under GDPR Arts. 15–22 you can request access, rectification, erasure, restriction, portability, object to processing based on legitimate interest, and withdraw consent at any time without affecting earlier processing. Write to novakuapp@gmail.com; we answer within one month. Because we hold no account data, we may ask for the purchase order number (GPA.…) from your Google Play receipt to locate purchase records.
You can also complain to the Spanish Data Protection Agency (AEPD, C/ Jorge Juan 6, 28001 Madrid) or the authority of your EU/EEA country.
9. Children
Stackborne is a general-audience arcade game and is not directed at children under 13. We do not knowingly collect personal data from children. If you believe a child has provided data, contact us and we will help delete it.
10. Security
All data sent by the app travels encrypted (HTTPS/TLS). The app requests no special permissions (no location, camera, microphone, contacts or files); it only uses the network for ads and purchases, and vibration for haptic feedback.
11. Changes
We may update this policy; the date at the top shows the latest version. Significant changes will be announced in the app or its store listing.
