Privacy Policy
What ClashDeckster collects, how it is used, how advertising and cookies work, and how to request deletion of your data.
Last Updated: November 2026
What We Collect
If you sign in with Google, we store your email address, name and profile picture from your Google account. We never receive or store your password.
When you look up a player, we store the public Clash Royale player tag, name and trophy count returned by Supercell's official API, so we can generate decks and improve our recommendations.
If you rate a generated deck, we store that rating along with the deck, and your email address if you are signed in.
When we generate a deck, we keep a record of it: the player tag, trophy count and King Tower level it was built for, whether you pressed Copy, and your account if you are signed in. We use this to learn which decks players actually take into the game.
If you save your own player tag, we keep it with your account so we can fill it in for you; if you are not signed in, it stays in your browser only. You can remove it at any time from the same menu.
We only send product emails to people who explicitly opted in — by ticking the optional box when signing up, or by accepting the in-app prompt. Signing in does not subscribe you.
These emails cover new features and Clash Royale meta updates. Every one of them has an unsubscribe link, and you can opt out at any time without losing access to anything. We do not sell or share your email address.
Cookies & Advertising
We use Google Analytics to understand how our website is used. Advertising on this site is managed by Journey by Mediavine. Mediavine and its advertising partners may use cookies, pixels and similar technologies, and may collect information such as your IP address, browser and device type, and the pages you visit, in order to show ads, limit how often you see them, measure their performance and, where allowed, tailor them to your interests.
In the European Economic Area, the United Kingdom and Switzerland, these technologies are only used for advertising and analytics after you agree to them in the consent message shown on your first visit. You can change or withdraw your choice at any time through the privacy settings control that message provides. Visitors in U.S. states with privacy laws can opt out of the sale or sharing of their personal information through the same controls.
Mediavine's own practices are described in the Mediavine Privacy Policy.
Your Rights
You may request a copy or deletion of your data, or withdraw email consent, by contacting us at hello@clashdeckster.com.
