DEFENCE

Hacker-themed tower defence.

The game

Threats follow the lit path toward your core. You build towers to stop them — and every wave gets harder. Runs are endless, but they always end: the wall catches up eventually. How deep you get is the score.

Between runs you spend what you earned in the Lab, making the next run reach further. Bosses are drawn from real malware, described technically — Morris Worm, Melissa, ILOVEYOU — with no country or attribution attached. The glitches you fight are real attack techniques.

Eight towers

Firewall, Chain, Honeypot, ICE Cannon, Zero-Day, Rootkit, Deep Probe, Crypto Miner.

Real threats

Bosses and glitches based on actual malware and attack techniques.

Endless runs

Five difficulty tracks. The exponential wall means every run ends.

No forced ads

Zero forced advertising. Opt-in only. Prices never rise.

Privacy policy

Last updated: 2 September 2026

Subnet Defence is developed by Keets Project (Stefan Ekström), Sweden. This policy explains what the app does and does not do with your information.

What we collect

Nothing. The app does not collect, transmit, or store any personal information on our servers. There is no account, no login, and no tracking.

The released app does not request the Android internet permission at all, so it cannot send data anywhere. There is no analytics, no crash reporting, and no advertising code in this version.

Data stored on your device

The game saves your progress locally on your device — your cores, upgrades, best waves, and settings. This data never leaves your phone. It is removed when you uninstall the app, and can be cleared at any time from the in-game settings ("Reset progress").

Reporting a bug

If you use the "Report a bug" button, the app opens your own email app with a pre-filled message. That message includes your device model, your Android version, the app build number, and which screen you were on — all of it visible to you in the draft before anything is sent. Nothing is sent unless you press send yourself.

If you do send it, your report — and the address it came from — lands in a Gmail mailbox, so it is stored with Google as the email provider. The technical details from a report — device model, Android version, build number, and the symptom you described — are copied into the project's bug notes so the issue can be tracked and fixed. Your email address is not copied there: the mailbox is the only place it is held.

A report is kept only while the issue it describes is open, and deleted once it is resolved. Your address is used to reply about that report and for nothing else — there is no mailing list, and it is never used for marketing.

Children

The app is not directed at children. It collects no information from anyone, regardless of age — that is true of the app itself, not of email: if you write to us, we have received your address. Bug reports from anyone under 18 should be sent by a parent or guardian, not by the child directly.

Changes

Future versions may add optional advertising or in-app purchases. If that happens, this policy will be updated before those features ship, and the change will be described here.
