Grand Line Spin ("we", "us", the "Site") respects your privacy. This policy explains what information is collected when you visit grandlinespin.com and how it is used.
The short version
The game runs entirely in your browser. We do not ask you to create an account, and we do not collect your name, email, or personal details to play. We use Google Analytics to understand general usage, and Google AdSense to display ads, both of which use cookies as described below.
Information we collect
- Gameplay data: Your crews and scores are generated and displayed in your browser. If you choose to submit a legendary crew to the leaderboard, only the pirate name you type, your score, and your crew snapshot are stored — never any personal information.
- Analytics data: We use Google Analytics to see how the game is played (pages visited, features used, approximate location, device and browser type). This data is aggregated and is not used to personally identify you.
- Local storage: We may store small preferences on your device (such as which mode you last played or whether you collapsed the info panel) so the site remembers them on your next visit. These stay on your device.
Advertising & cookies (Google AdSense)
This Site is supported by advertising served through Google AdSense. Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this and other websites.
- Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to this Site and/or other sites on the Internet.
- You may opt out of personalized advertising by visiting Google Ads Settings.
- You can also opt out of some third-party vendors' use of cookies for personalized advertising at aboutads.info/choices.
- For more on how Google uses data when you use our partners' sites or apps, see Google's Privacy & Terms.
If you are in a region that requires consent for personalized advertising (such as the EEA, UK, or Switzerland), Google's consent mechanism will ask for your choices before such ads are shown.
How data is used
We use aggregated analytics only to improve the game — deciding which features to build, fixing bugs, and understanding how many people play. We do not sell your data, and we do not use it to identify you personally.
Children's privacy
This Site is intended for a general audience and is not directed at children under 13. We do not knowingly collect personal information from children.
Your choices
You can block or delete cookies through your browser settings, use the ad-personalization opt-outs linked above, and clear the site's local storage at any time. The game will still work with cookies disabled, though some ads may be less relevant.
Changes to this policy
We may update this policy from time to time. Any changes will be posted on this page with an updated date above.
