Privacy Policy — Piggy Tower
Last updated: November 3, 2026
DukItan Software built the Piggy Tower game, which you can play in full without an account. This page explains what data the game uses, why, and how you control it.
1. Data stored only on your device
Progress (coins, records, characters, upgrades, items), preferences, daily gifts and reminders are saved on your device. They do not leave it unless you make a cloud backup (section 2).
2. Google or Apple account (optional)
If you sign in with Google or, on iPhone, with Apple, we receive an account identifier, your name and your e-mail through Firebase Authentication. With Apple, the name is only shared if you allow it, and the e-mail may be Apple’s hidden address. They are used for:
- Cloud backup: a copy of your progress is kept in Cloud Firestore, accessible only to your account;
- Leaderboard: a nickname (your first name, or “PiggyNNNN” when the name looks like an e-mail) and your best height are shown publicly. Your e-mail is never shown.
You can sign out at any time and delete your account in Settings. This erases the backup and your leaderboard entries.
3. Usage and crash data (anonymous)
To balance the difficulty and fix bugs, we use Firebase Analytics and Firebase Crashlytics.
- Analytics: game events such as run start and end, height reached, biome, what ended the run, bosses beaten, items bought with coins and gifts collected. Firebase also collects technical data automatically: an app-instance identifier, device model, operating system, language and approximate country.
- Crashlytics: crash reports, with the error trace, device model, operating system and the biome/height at the time of the crash.
We do not send your name, e-mail or account with these events. In these events, we do not collect the advertising ID, and ad-personalisation signals are off. You can turn all of this off in Settings → Share usage data.
4. Purchases
Real-money purchases are processed by Google Play or the App Store. We never receive or store payment details. We only receive the purchase confirmation, so we can deliver the pack.
5. Notifications
Reminders (daily gift and free chest) are local notifications, scheduled on your device, with no server. They only appear if you allow them, and you can turn them off in Settings → Reminders.
6. Ads
When you fall, you can choose to watch a rewarded video to get a second chance. It is always optional: no video starts on its own and there are no banners during a run. The videos come from Unity LevelPlay (Unity Technologies) and its partner ad networks. We ask them for non-personalised ads only: we do not allow your data to be used for targeted advertising and we do not ask for tracking permission on iPhone. Even so, to show the video, limit repeats and prevent fraud, these companies may collect technical device data such as IP address, model, operating system and, on Android, the advertising ID, which you can reset or delete in Android settings.
7. Sharing and storage
The data in sections 2 and 3 is processed by Google (Firebase) as a processor, on servers that may be outside your country, under Google’s safeguards. The technical data in section 6 is handled by Unity LevelPlay and its partner networks, under their own policies. We do not sell data. Usage data is kept for the Firebase Analytics default period (up to 14 months). The backup and leaderboard entries are kept until you delete your account.
8. Children
The game is not directed at children under 13, and we do not knowingly collect children’s data. If you believe a child has sent us data, write to the contact below and it will be deleted.
9. Your rights
You can ask for access, correction, portability or deletion of your data, and withdraw consent at any time, at the e-mail below. We reply within 15 days.
