Tanker Defense privacy policy

0cog Inc. makes Tanker Defense.

Tanker Defense runs entirely in your browser and doesn't collect personal data. It has no accounts, no advertising and no analytics, and it makes no network requests beyond loading the game itself.

The number of sorties you've flown, your best score and grade for each difficulty, the difficulty you last picked and whether you've seen the instructor's notes are saved only in your browser's local storage on your device. Clearing the site's data in your browser deletes them.

Questions: contact 0cog Inc. through zerocog.us.
