Skyscraper 4D LLC ("we") makes the Skyscraper 4D app for iPhone and iPad and runs skyscraper4d.com. This policy explains what data the app and the website collect, why, who receives it, how long it is kept, and the choices you have.

In short: the app has no accounts and shows no ads. We don't track you across other companies' apps or websites, and we don't sell your data. We collect crash reports and usage statistics to keep the game working and to improve it, and we receive what you choose to send us through the in-app feedback form.

Crash reports and diagnostics (Firebase Crashlytics, a Google service), sent automatically:
• crash logs, and errors the app records itself;
• your device model and memory, iOS version, app version, language, region setting, and mobile carrier name where iOS provides it;
• how many times you have opened the app;
• a random ID the app creates the first time it runs. It is not your name, email address or Apple Account;
• a record of certain moments in the game, such as finishing the tutorial, seeing the upgrade screen, or buying or restoring an upgrade (with its product and price).

Usage statistics (Google Analytics for Firebase), sent automatically:
• an ID for each installation of the app;
• when and for how long you use the app, and which screens you view;
• in-app purchases, with the product and price;
• your device model, iOS version and app version;
• your approximate location (such as your country or city), which Google works out from your IP address. The app never uses GPS or Location Services.

Feedback and bug reports (Instabug, now called Luciq), only when you open the feedback form (Report a Bug or General Feedback) and choose to send a report:
• your message, and your email address if you enter it (it is optional);
• a screenshot of the app, and any images, screen recordings or voice notes you attach;
• your device details, the random ID and diagnostics described above, the steps you took in the app before sending, and app and network logs.
Once the form has been opened, Instabug may also send crash and performance reports until the app is closed.

Purchases. Apple processes all payments, and we never see your payment details or your Apple Account. The app asks Apple which upgrades your Apple Account owns so that it can restore them.

iCloud. The app keeps some settings and progress in your own iCloud account so they follow you across your devices. Apple stores this data, and we cannot access it.

Your cities are saved on your device and are not sent to us.

• To find and fix crashes and bugs.
• To understand how the game is played, so we can improve it.
• To read and reply to your feedback.
• To restore the upgrades you have bought.

We do not use your data for advertising, we do not track you across other companies' apps or websites, and we do not sell your personal information.

• Google receives crash reports and usage statistics through Firebase Crashlytics and Google Analytics for Firebase (Firebase privacy, Google Privacy Policy).
• Instabug (Luciq) receives the feedback and bug reports you send (Luciq Privacy Policy).
• Apple processes purchases and stores your iCloud data (Apple Privacy Policy).

These companies process the data on our behalf, and we only use providers that protect it at least as well as this policy describes. Their servers may be outside your country, including in the United States.

• Crash reports: 90 days, after which Google starts deleting them.
• Usage statistics: Google keeps data tied to an installation for up to 14 months. Totals that identify no one, such as daily player counts, are kept longer.
• Feedback and bug reports: until we no longer need them to reply to you or to fix the problem.

• Sending feedback is always your choice, and adding your email address is optional.
• Crash reports and usage statistics are tied to random IDs, not to your name or email address. Deleting the app resets those IDs, so anything collected afterwards is not connected to what came before.
• You can ask us to access, correct or delete your data by emailing us. We can find feedback you sent by your email address. Because crash reports and usage statistics are not tied to your identity, we usually cannot tell which records are yours, and they are deleted on the schedule above.

If you are in the European Economic Area or the United Kingdom, we rely on our legitimate interests to collect crash reports and usage statistics (keeping the game working and improving it), on your consent for feedback you choose to send, and on our contract with you to restore purchases. You can object to processing based on legitimate interests, withdraw your consent, and complain to your local data protection authority.

If you are in California, we do not sell or "share" your personal information as California law defines those terms.

Skyscraper 4D is not directed at children under 13, and we do not knowingly collect personal information from them. If you believe a child has sent us personal information, for example an email address in a feedback report, contact us and we will delete it.

The app sends crash reports, usage statistics and feedback over encrypted connections, and this website is served over HTTPS.

Our own pages do not set cookies or run analytics or ads. Cloudflare delivers the site, and pages load fonts and scripts from Google Fonts, Google Hosted Libraries and cdnjs, so those services receive your IP address when you visit. The home page and press kit embed videos from YouTube and Vimeo, which may set their own cookies under their own policies.

If our practices change, we will update this page and the date below.

For questions about this policy or your data, email us at [email protected].
