Privacy Policy

DeckSequence is operated by Ayax Dev Studio LLC, a Delaware limited liability company ("we," "us," or "our"). We respect your privacy. This Privacy Policy describes how we collect, use, store, and protect information when you use the DeckSequence website and applications, including our mobile apps (collectively, the "Services").

Information We Collect and How We Use It

DeckSequence is a free, account-based tool for tracking your Pokémon Trading Card Game results. We collect only what the Services need to work:

• Account information. When you create an account we collect your email address and authentication identifiers through our authentication provider (Better Auth), including identifiers from any social sign-in provider you choose to use, and the session data needed to keep you signed in.
• Your Pokémon TCG Live username. If you provide it, we store the in-game username you enter so your imported games can be attributed to you. It may also appear inside the raw battle logs you paste in.
• The data you create. The matches, decks, deck versions, replays, and share links you record are stored so we can show them back to you, build your analytics, and power any links you choose to share.
• Product analytics. We use PostHog to understand how the Services are used and to diagnose problems, which involves limited usage and device information such as pages visited, actions taken, browser and device type, and IP address.

We use this information to provide and maintain the Services, generate your match and matchup analytics, keep your account secure, improve features, and comply with applicable legal obligations. DeckSequence is free, so we do not collect payment or billing information.

Sharing, Retention, and Security of Information

We do not sell your personal information. Your account and the data you create are private by default. Nothing is shared publicly unless you create a share link, and you can revoke a share link at any time. We share information only with the third-party providers that operate the Services on our behalf (such as our hosting, database, authentication, and analytics providers), and only to the extent needed to run the Services, or where required to do so by law.

We retain your information for as long as your account is active or as needed to provide the Services, unless a longer retention period is required or permitted by law.

We take reasonable administrative, technical, and organizational measures designed to protect information from unauthorized access, use, alteration, or disclosure. However, no method of transmission or storage is completely secure, and we cannot guarantee absolute security.

Your Choices, Updates, and Contact Information

You may choose not to provide certain information, though doing so may limit your ability to use some features. You can delete the data you create, and depending on your location you may have additional rights regarding your personal information under applicable laws.

You can permanently delete your account and all of its data at any time from inside the Services (Profile → Delete account on mobile, or Account settings on the web). See our account deletion page for details, including how to request deletion if you can no longer sign in.

We may update this Privacy Policy from time to time. Any changes will be reflected by updating the "Last updated" date at the top of this page.

If you have any questions about this Privacy Policy, or want to exercise your rights over your personal information (including account deletion), contact us at privacy@decksequence.com or visit our Support page.
