Who we share it with
We do not sell your personal information for money. We share it only with service providers that run the Game for us:
- Google (AdMob): Google Privacy Policy, how Google uses data from partner apps.
- Cloudflare hosts our server that stores the ranking and play statistics: Cloudflare Privacy Policy.
- Apple and Google process payments under their own policies.
We may also disclose information if the law requires it, or to protect the Game and its players from fraud or abuse.
These providers may process data outside your country, including in the United States. Where required, they use safeguards such as the European Commission's Standard Contractual Clauses.
Your choices
- Personalized ads. On Android, go to Settings › Google › Ads (or Settings › Privacy › Ads) and delete or reset your advertising ID. On iPhone, the Game does not track you across other companies' apps unless you allow it; you can change this in Settings › Privacy & Security › Tracking.
- Ad consent (EU/UK). You are asked before personalized ads are shown.
- Ads are optional. Ads only play when you tap a button to watch one for a reward.
- Deletion. Deleting the Game removes your progress from your device. To remove your ranking records and play statistics from our server, email us from the Game's support page; tell us your nickname and the floor you reached.
- Access and correction. Email us and we will send you a copy of your data or correct it.
Depending on where you live (for example the EU, UK or California), you may have further rights, such as objecting to processing, restricting it, or complaining to your data protection authority. We will not treat you differently for using these rights.
Legal basis
If you are in the EU or UK: we process ranking and purchase data to provide the Game you asked for (contract); play statistics to improve and secure the Game (legitimate interests); and personalized advertising data only with your consent where it is required.
How long we keep it
Ranking records are kept while the ranking runs or until you ask us to delete them. Play statistics are kept for up to 14 months. Support emails are kept for up to 3 years so we can follow up on past issues. Records we must keep by law, such as for purchases, are kept for as long as the law requires.
Children
The Game is not directed at children under 13. We do not knowingly collect personal information from children. If you believe a child has given us information, email us and we will delete it.
Security
Data is sent over encrypted connections (HTTPS), and requests to our server are signed by the Game. No method of storage or transmission is completely secure, but we work to protect your information.
Changes
If we change this policy, we will update the date at the top of this page. For significant changes we will also tell you in the Game.
