The ancient systems of the keep have fallen silent. Circuits are broken, magnetic chambers are unbalanced, and lightning signals are escaping. Enter and become the new Keeper.
Every chamber of the keep introduces a different style of challenge — each one mastered on its own terms, each one feeding energy back into the restoration.
Reconnect broken energy paths by rotating and placing circuit tiles until a continuous line runs from source to terminal. Three levels of rising complexity, each with its own circuit architecture.
React to fast-moving electrical signals tearing through the tunnel. Catch the correct charge, avoid deceptive decoys, and build combo chains under pressure. Speed and pattern recognition.
Control attraction and repulsion to navigate a charged particle through three polarity routes. Flip the field to pull or push past barriers — get the polarity wrong and the particle reverses.
Recover, inspect, and stabilize mysterious energy relics sealed inside the archive. Rotate relics in three dimensions, mark favourites, and connect an active relic to the main Control Deck.
Every completed challenge feeds into your Keeper Records. Victories, efficiency ratings, combos, magnetic pulse records, and relic discoveries are all tracked and transformed into a five-axis profile.
The Voltage Vault holds a collection of charged artifacts — each one with a unique appearance, rarity level, and archive record. Rotate them in three dimensions and discover what they once powered.
3D inspection — rotate every relic in three dimensions before adding it to the archive
Rarity tiers — common, rare, epic, and legendary relics with individual archive records
Control Deck link — connect an active relic to the main Control Deck for a permanent bonus
Complete challenges to reveal achievements hidden inside the Storm Seal Wall. Some conditions remain encrypted until you complete them.

This privacy policy applies to the Thunderkeep app for mobile devices, together with any related services operated by Ando Metsaru (collectively, the "Application"). Ando Metsaru is hereby referred to as the "Service Provider".
The Application does not collect, log, or store any personal information when you download and use it. Registration is not required. If the Application is used with an active internet connection, technical protocol data (such as your ephemeral IP address) is transmitted to facilitate network connectivity, but this data is not retained or used for tracking.
This Application does not collect precise information about the location of your mobile device.
Since the Application does not collect any information, no data is shared with third parties.
Since the Application does not collect personal information through normal use, uninstalling it simply removes the Application from your device.
If you contact the Service Provider directly or voluntarily provide information by other means, you may request deletion of that information by contacting [email protected].
The Application is not intended for children under 13 years of age, or such higher age as required by applicable law. The Service Provider does not knowingly solicit data from children or market to them. Since the Application does not collect personal information through normal use, children's data is not at risk from use of the Application alone. If you voluntarily provide personal information through other means and are under 13 years of age, your parent or guardian must provide consent on your behalf where permitted by law.
Because the Application does not collect personal data, the risk of personal data exposure is minimal. However, no security system is completely secure. The Service Provider implements reasonable safeguards to protect systems and any data it holds.
Since the Application does not collect personal data through normal use, the risk of a data breach affecting your personal data is minimal. If a breach occurs involving any data you have voluntarily provided, the Service Provider will notify you as required by applicable law.
The Service Provider may update this Privacy Policy from time to time. The Service Provider will notify you of material changes by posting the updated Privacy Policy with an effective date. Where required by law, the Service Provider will seek your consent to material changes before they take effect.
Previous versions of this Privacy Policy will be maintained and made available upon request by contacting the Service Provider at [email protected].
If you voluntarily provide information to the Service Provider and processing is based on consent, you may withdraw that consent at any time without affecting processing carried out before withdrawal.
If you have any questions regarding privacy while using the Application, or have questions about the practices, please contact the Service Provider via email at [email protected].
This privacy policy is effective as of 2026-08-25
