Privacy & ads

Updated 21 October 2026

Your aquarium stays on your device.

Oddwater saves your aquariums, unlocked companions, chosen crew and sound preferences in your browser’s local storage. The game has no account or login. Clearing site data removes these saves. A different browser or website address has its own saved progress.

One banner, outside the water.

The public game can show a 300×250 Adsterra banner above the play area. The game works when ads are unavailable or blocked. There are no rewarded ads, ad-linked purchases or automatic refresh timers.

Adsterra and its advertising partners may receive information such as your IP address, browser/device details and the website showing the ad. Their ads may use cookies or similar technology. Read Adsterra’s privacy information for their practices.

The banner uses Adsterra’s standard script directly in the game page. Third-party scripts can access browser information available to that page. Clicking an ad may open an external website. Oddwater does not load this banner when your browser signals Global Privacy Control. You can also hide banners on this device:
