Terms of Use
Circuit Defense
Last updated: October 12, 2026
Circuit Defense is a game for entertainment. Progress and virtual rewards are stored locally. Keep your device backup settings in mind: the app does not provide a developer-operated cloud backup or progress transfer service.
1. About these terms
Circuit Defense is provided by Mikhail Sterlikov (“we”, “us”, “our”). Your license is governed by Apple’s Standard Licensed Application End User License Agreement. These terms supplement it and do not replace it. In a conflict the standard agreement controls, subject to applicable law.
2. The game
The app provides procedural tower defense runs, tower modules, mutations, an Endless mode and persistent core progression. Difficulty, rewards and compatibility may change with updates. Progression and winning are not guaranteed.
Some abilities, such as the Spike Sphere, are steered by tilting your iPhone. Play in a safe place, hold the device securely and be aware of your surroundings. Do not use tilt controls while driving, walking or doing anything that needs your attention.
3. Virtual rewards
Gold, fragments, modules and components are in-game items. They have no monetary value, cannot be redeemed for cash and are not transferable between players. The current version offers no in-app purchases or subscriptions. Spending fragments uses earned game currency and does not charge money.
4. Local saves
Run history and progression are stored on your device. Automatic saves and recovery copies reduce the risk of lost progress but cannot guarantee recovery in every situation. An interrupted wave resumes from its beginning. Deleting the app removes local data; Apple backups are managed separately. We cannot restore progress from our servers.
5. Responsible use and ownership
Use the app lawfully and respect the rights of others. The app’s software, artwork and other materials remain owned by their respective rights holders; your license does not transfer ownership. These terms do not restrict rights that applicable law expressly grants you.
6. Price and services
Any download price is shown in the App Store. The current version has no ads, subscriptions or in-app purchases. If paid features are introduced, prices and conditions will be presented before purchase; current use does not authorize future charges.
Gameplay works offline. Updates, website links, email support and Apple services may require internet access and are subject to those services’ terms.
7. Privacy
See our Privacy Policy for local game information, support correspondence, Apple services and website hosting.
8. Updates and support
We may update the app to fix issues, adjust balance or support newer devices. Features and compatibility can change. We do not promise indefinite support for every device or operating-system version. You may stop using the app at any time.
9. Warranties and liability
To the extent permitted by law, the app is provided “as is” and “as available”, without additional promises that it will always be error-free. Apple’s standard license warranty and liability provisions apply. Nothing here excludes mandatory consumer rights or liability that cannot lawfully be excluded.
10. Changes
Updates to these terms will appear here with a revised date. Where required, we will provide additional notice or request agreement. Changes do not remove accrued rights.
