Privacy policy

Effective November 11, 2026

Quasi Convex Union, California, USA, operates Dino Battle. Contact ask@convex.io with privacy questions or requests.

Guest play stays on your device

Guest adventures are stored in your browser, not uploaded to our account database. They include dinosaur choices, game progress, items, and any camp or dinosaur name you choose. Clearing site data removes locally stored adventures and sign-in information.

Accounts, saves, and payments

For accounts, we store the account email, account identifiers, and subscription information. Signing in uses email codes or links. Your browser stores session credentials, cached account saves, and temporary checkout information so the game can restore your session and purchase.

When you open subscription checkout, we store a random offer identifier in your browser and record the offered price, discount, and assignment date. We use these to keep your offer consistent and compare subscription offers. After signing in or subscribing, the offer may be associated with your account. Assignment does not use your game progress or personal profile.

When you claim an adventure or play through an account, account saves contain the adventure name, identifiers, update timestamps, and game state, such as dinosaurs, inventory, and progress. We use these to restore adventures, sync devices, and resolve conflicting updates. Saves are private to the account and are not publicly posted.

Our payment provider collects payment and billing details through its payment form. We receive the checkout email, customer and subscription references, payment status, and billing information needed to manage the subscription, such as invoices and the payment method's brand and last four digits. Our application does not receive or store full card numbers or security codes.

Children and parent-managed accounts

Children can play without creating an account. An adult must manage subscriptions, and a parent or legal guardian must manage an account used by a child. Account and checkout email fields are intended for that adult.

We do not ask children for their real name, email, age, address, photographs, voice, or precise location. Please use made-up camp and dinosaur names and do not put personal details in them or in support messages. Game identifiers and saved progress are used to operate the game and restore adventures, not to target advertising. A parent can contact us to review or request deletion of information associated with their account or child.

Service providers and technical information

We use service providers for hosting, accounts, authentication, cloud saves, email delivery, and payment processing. These providers process the information needed to deliver their services.

Our application does not store IP addresses. Hosting and other service providers may process technical information such as IP addresses, browser information, and request logs for delivery, security, fraud prevention, and their other disclosed service purposes. Our hosting provider logs visitor IP addresses for security. Payment providers may use their own cookies or similar technologies, as described in the notices and privacy policies available in the payment form.

We use account data to provide the game, authenticate access, manage purchases, respond to support requests, and protect the service. Providers may process data outside your state or country. We may disclose information when required by law or reasonably necessary to protect users or the service.

Basic usage statistics

We use a random browser-tab identifier, basic gameplay and subscription activity, and broad referral sources to understand usage and improve Dino Battle. These statistics are stored separately from adventures with restricted access. They are not used for behavioral advertising, tracking across websites, or building individual profiles.

We delete session records and temporary purchase references after 30 days. Totals without identifiers are kept for one year.

Advertising and tracking

We do not sell personal information or share it for cross-context behavioral advertising. We do not add advertising networks or third-party analytics to gameplay. We do not use game data to track you across unrelated websites. Our application does not change its behavior in response to browser Do Not Track signals.

Retention and your choices

Local data stays in your browser until you delete it or clear site data. Account data and cloud saves are retained to operate your account and preserve adventures for your return, including after a subscription ends. Cancellation stops billing renewals; it does not delete your account or saves.

Email ask@convex.io to request access, correction, an export, or deletion of account information and saves. We will verify your authority before acting. You may also ask us to stop further collection associated with your account. We may retain limited records where necessary for legal obligations, accounting, disputes, or fraud prevention; provider backups and logs follow their applicable retention schedules. Deleting an account does not clear copies already stored in your browser.

Changes

We will update the effective date when this policy changes. For material changes, we will provide notice in the game or by email before they take effect and obtain consent where required.
