Blasonia

Privacy policy

Last updated: October 18, 2026

This policy explains what data Blasonia uses, why, who it is shared with and how you can have it erased. Blasonia does not ask for your name or age, only asks for an email address if you choose to create an account with it, shows no ads and uses no analytics or tracking tools.

Who we are

Blasonia is published by Djoox Studio, a brand of CERTYNEO, 14 rue Beffroy, 92200 Neuilly-sur-Seine, France, which is the controller of your data.

For any question or request: contact@djoox.com.

The data we use

• Account: on first launch, a guest account is created automatically (a technical identifier, with no name or email address). This account is shared by Djoox Studio games.
• If you secure your account (optional): your email address, or the identifier and email address that Google or Apple send us if you choose to sign in with them. There is no password: email sign-in uses a one-time code.
• Previous profile: profiles created before accounts (an identifier generated at random by your device) are attached to your account on first launch.
• Player name: suggested automatically and editable. Other players see it in leaderboards, lobbies and matches. Do not use your real name.
• Game: league and league points, a skill rating used only to find opponents of your level, wins and losses, collection (hero cards, crowns, hero levels), chests and their unlocking. During a match, your actions (purchases, hero placement) are processed by the server, which does not keep them once the match is over.
• Server technical logs: IP address, date and time, requested address and browser or device type, recorded on every exchange with the server.
• Performance test (optional): only if you start it yourself from Settings, the game sends the graphics processor model, screen size, browser or device type and the measured smoothness.
• On your device only: your account session, the previous profile identifier, the chosen language, settings (sound, tips, graphics quality) and whether you have seen the tutorial.

Why we use it

• To run the game: online matches, leaderboards, leagues, collection and chests (performance of the service you use).
• To let you find your progress on several devices and never lose it, if you secure your account (performance of the service you use).
• To find opponents of your level and keep matches fair (legitimate interest).
• To keep the server secure, detect abuse and fix outages, using the technical logs (legitimate interest).
• To make the game smoother on older devices, using the performance test, only if you start it (consent).

We do not sell your data and do not use it for advertising or commercial profiling.

Who it is shared with

• The game and Djoox Studio account servers: our own servers, located in the European Union. No other company receives your game data.
• Resend (Resend, Inc., United States): only if you choose email sign-in, it receives your email address to send you the sign-in code.
• Google and Apple: only if you choose to sign in with them; sign-in happens on their pages, under their own privacy rules.
• Other players: they see your player name, league and results in leaderboards, lobbies and matches.
• Google Play and the App Store: they distribute the app and apply their own privacy rules to downloads. Blasonia contains no in-app purchases.

How long we keep it

• Account, email address, player name and game data: as long as your account exists. When you delete it, they are erased from our servers immediately.
• Technical logs: erased automatically over time, the oldest being removed as soon as the planned volume is reached.
• Performance tests: 12 months at most.

Your rights

You can access your data, correct it, have it erased, obtain a copy, object to certain uses or ask for them to be restricted, and withdraw your consent at any time.

• Delete your account: directly in the game, Settings > My account > Delete my account. Your account is deleted for all Djoox Studio games, along with your Blasonia progress, immediately.
• Without the game: write to contact@djoox.com from your account’s email address, or with your player name (we may then ask for a screenshot of the game to check that the account is yours). We delete it within 30 days.
• Uninstalling the game erases the data kept on your device.

If you believe your rights are not respected, you can complain to the French data protection authority (CNIL, www.cnil.fr) or to the authority of your country.

Children

Blasonia does not ask for a name or age, only asks for an email address if you choose to create an account with it, contains no ads or real-money purchases, and has no chat with other players. We advise children not to use their real name as their player name. If you are a parent and want your child’s profile erased, use Settings > My account > Delete my account or write to us.

Security

Exchanges between the game and our servers are encrypted (HTTPS). Server access is restricted to the team that runs them. Your account session is kept only on your device; the game never knows any password (one-time codes, or sign-in on Google’s and Apple’s pages).

Changes

If this policy changes significantly, we will let you know in the game before the changes apply. The date of the last update is shown at the top of this page.
