Privacy Policy

Crypto City is designed to work without knowing who you are. There is no registration, and we never ask for your name, e-mail address, phone number, date of birth, location, contacts, payment details or a cryptocurrency wallet.

What we store. When you tap Start Building, the app creates a random installation identifier and our server creates an anonymous guest record with a city. We store your city (its name, buildings, levels, districts, City Coins and settings), the times it was created and last used, and securely hashed sign-in tokens for your installation. The tokens themselves are kept only in the secure storage of your phone.

Technical logs. Like any internet service, our server briefly processes your IP address to deliver the app and to limit abuse. Access logs are kept for a short period for security and troubleshooting and are not used to identify you.

What we do not do. We do not sell personal data, show third-party advertising networks, or use analytics or tracking software development kits in the app.

Market data. Prices are fetched by our server from Twelve Data. Your phone talks only to our server, so the data provider does not receive your requests.

Sponsored links. If you choose to tap a sponsored eToro link, we count the click (without your identity) and your browser opens eToro's website. From then on eToro's own privacy policy applies. We may earn a commission.

Deleting your data. Settings > Delete City permanently deletes your city, its history and your sign-in tokens from our server and clears the app. Because there is no account, we cannot find or restore a city after it is deleted, or after the app is removed from your phone.

Children. Crypto City is intended for adults and is not directed at children.

Changes and contact. We will update this policy in the app if it changes. For questions, contact the developer through the support address shown on the app store page.
