Privacy policy

Last updated 18 October 2026.

This policy covers this website, tsunagubit.com, and the apps and games TsunaguBit makes, starting with Techno Tower Defense. The short version: we do not collect personal data.

This website

• No cookies, no analytics, no advertising, no tracking of any kind.
• Fonts and images are served from this site itself; no third-party scripts are loaded.
• The site is hosted on Google Cloud (App Engine). Like any web host, Google keeps standard request logs (IP address, browser, the page requested and the time) to run and protect the service. We use them only to keep the site working.

Techno Tower Defense

• The game has no accounts and makes no network connections of its own.
• Your progress, settings and achievements are saved only on your own device.
• The game collects no personal data, analytics or crash reports.

Stores and platforms

When you get the game from a store or play it on a platform (for example itch.io, the App Store, Game Center or Steam), that service handles your account, purchases and any data it keeps under its own privacy policy.

Children

Because we collect nothing, we collect nothing from children either.

Changes and contact

If this policy changes, the new version will be posted here with a new date. Questions are welcome on the support page.
