Data used to offer the service

Without counting, the browser saves preferences and matches in local storage. When you create an account, we use Firebase Authentication to identify you by name, email, and user ID. When accessing with Google, we receive the profile information authorized by you. Passwords are managed by Firebase Authentication; are not stored in Deckopedia documents.

Firestore stores account-associated data, such as preferences, progress, statistics, and inventory, depending on available resources. Firebase and Google Cloud services may also process technical information, such as IP address and security logs, to run and protect the service.

Purposes and storage

We use the data for authentication, match continuity, personalization and account operation. The storage required for the service remains active. Local data remains until removed in the browser; Account data is kept as long as necessary for the provision of the service, security and applicable obligations. Deletion requests are received via the contact above.

Choose Brazilian Portuguese or English in the header. Your language preference is stored in a functional cookie and in your browser’s local storage.

Purchases and payments

Stripe processes payments in its secure checkout. We link your account to customer and purchase identifiers to confirm coins, ad removal, refunds and disputes. We do not receive or store full card numbers or CVCs. Local test environments are separate from real payments. For purchase questions or requests, use the contact above. See the Stripe privacy policy.

Optional advertising

Deckopedia reserves spaces for Google AdSense. Ads are only prompted when the integration is enabled and you allow advertising. Refusing does not prevent playing. When enabled, Google may use cookies, identifiers, and browsing information for ad delivery and measurement in accordance with its own policies. We do not sell your account data.

Read how Google uses data from partner sites and the Google privacy policy. Providers may process data outside Brazil.

You can request information, access, correction or deletion of personal data, clarify sharing and revoke consent for advertising through the contact information provided on this page. To serve you securely, we may need to confirm that the account belongs to you. Changes to this policy will be posted here.
