Techno Tower Defense is a neon cyberpunk tower defense for iPhone, iPad and Mac. You are Architect Construct 7, a defence AI guarding the Core of the Megagrid. Build a maze of walls and guns, read the enemy’s counter-moves, and find out who the intruders really are.

This page is a quick guide, the place for support, and the game’s privacy policy.

How to play

Build the maze

Intruders walk from the gates to the Core. Place Blocks to force them down the longest route you can draw, and put your guns where that route passes by. Destroyed intruders drop RAM, which you spend on more nodes and upgrades.

Evolve your nodes

Nodes level up, and at level 3 each one chooses a branch: a Compiler becomes a Railgun or a Chain-Laser, a Firewall a Searing Wall or a Cryo-Lock. New pieces unlock as a sector goes on: shooters, blockers, control pieces and support nodes, each with a job the others cannot do.

Watch the Director

Late in a sector the enemy studies your board and builds the next wave against it: armour against small guns, fliers against walls, a flank through the gate you left unwatched. The ARCHITECT LOG tells you what is coming, so you have the break between waves to answer it.

Grow between missions

Securing a sector earns CPU Cycles. Spend them in the Overclock Hub to evolve your arsenal and start every sector stronger. Play on Easy, Normal or Hard.

Privacy Policy

Last updated: October 15, 2026

Techno Tower Defense does not collect, store, or transmit any personal data.

What stays on your device

The game saves three things, only on your own device, so it can pick up where you left off:

  • Settings — volume, language and similar options.
  • Progress — which sectors you have secured, your stars, and your Overclock Hub upgrades.
  • A performance log — frame rates from your recent waves, kept locally to help diagnose slowdowns. It is never sent anywhere.

Deleting the game deletes all of it.

Data collection

  • No accounts. There is no sign-up or login.
  • No analytics or tracking. The game contains no third-party analytics, advertising, or tracking SDKs.
  • No network. The game has no backend, makes no network connections, and sends nothing off your device.

Because no data is collected, none is shared with or sold to third parties.

Children’s privacy

Techno Tower Defense does not collect any data from anyone, including children.

Changes to this policy

If this policy changes, the updated version will be posted on this page with a new “last updated” date.
