Privacy policy

Firefly Trail (“the game”) is a logic puzzle game for Android published by ND Inovation Groupe (Paris, France) under its Artronic brand (“Artronic”, “we”). This policy explains what happens to your data when you play.

In short

Your progress stays on your device. Artronic collects no personal data such as your name, email or location, and has no server. The game shows ads from Google AdMob, which processes some data as described below (in Europe, the UK and Switzerland, only with your consent for personalized ads). It can measure anonymous usage statistics, but only if you accept when it asks. Optional in-game purchases exist, handled entirely by Google Play, and the “Remove ads” purchase turns the ads off.

Data stored on your device

To remember your game, Firefly Trail saves the following on your device only:

• the grids you solved, your times and stars, your daily streak and your achievements;
• the grid you are playing, so you can resume it;
• your profile (the player name you choose or the one drawn at random, and your figurine) and your weekly league (points, rank and past weeks). The other players of the league are simulated by the game on your device: your name and points are never sent anywhere;
• your settings (language, theme, colorblind colors, sound effects, vibration, daily reminder).

This data never leaves your device. You can delete it at any time with Settings → Erase my progress in the game, by clearing the app's data, or by uninstalling the game.

Data we collect

Artronic has no account system and no server of its own. The game does not access your contacts, location, camera, microphone or files. Artronic itself collects nothing. Two Google services can process data: the ads (Google AdMob, see below) and the optional usage statistics, which are off until you accept.

Anonymous usage statistics (optional)

After your first finished grid, the game asks whether we may measure anonymous usage statistics. If you say yes, the game uses Google Firebase Analytics to receive events such as: a level started or finished, its size and difficulty, the time taken, the stars earned, hints used, purchases made in the Shop, and basic technical information (app version, Android version, device model, country and language). No name, email or account is collected, and the statistics do not use the advertising ID. The purpose is to see which levels are too hard and to improve the game. The data is processed by Google (see Google's Privacy Policy and Firebase's privacy information) and is kept in a project owned by Artronic. You can change your choice at any time with Settings → Share anonymous usage statistics; turning it off stops the collection immediately. If you say no, nothing is sent.

Permissions

• Vibration: short vibrations as you draw your trail. You can turn them off in the game's settings.
• Notifications (optional): if you turn on the daily reminder, the game schedules a notification on your device at the time you choose. It is created and shown by your phone: no server is involved. You can turn it off in the game or in your phone's settings.
• Internet and network state: to load the ads and, if you accepted the statistics, to send them; the game itself plays fully offline.
• Advertising ID (AD_ID): used by Google AdMob, see below. You can reset or delete it in your phone's settings (Google → Ads).
• Billing: lets Google Play handle the optional purchases: “Remove ads”, “Premium packs” (the 7×7, 8×8 and 9×9 puzzle packs) and packs of hints (10, 30 or 100).

Sharing your result

The Share button only opens your phone's share sheet with a short message you can edit. Nothing is sent unless you choose an app and send it yourself.

Purchases

Firefly Trail offers optional purchases from its Shop: “Remove ads” and “Premium packs” (one-time purchases that stay unlocked), and packs of 10, 30 or 100 hints (consumable: hints are added to a stock kept on your device and used up as you play). Payments are handled entirely by Google Play: Artronic never sees your payment details, name or card. The game only learns from Google Play whether a purchase was made, so it can unlock the content or add the hints, and it stores the result on your device. “Restore purchases” in the Shop or the settings asks Google Play again after a reinstall or on a new phone; unused hint packs are consumed at purchase and cannot be restored. See Google's Privacy Policy.

Advertising (Google AdMob)

The game shows a full-screen ad now and then between two grids (never during a grid, never in your first grids), and offers optional videos you choose to watch, for example to get a hint or a streak freeze. Ads are provided by Google AdMob. To show ads, measure them and prevent fraud, Google may collect and process your device's advertising ID, IP address, approximate location derived from it, device and app information, and how you interact with the ads. In the European Economic Area, the United Kingdom and Switzerland, the game asks for your consent with Google's consent form before personalized ads are shown; you can change your choice at any time with Settings → Ad privacy choices. The “Remove ads” purchase turns off all ads: what a video would give is then given without one.

Children

The game is intended for players aged 13 and over and is not directed at children. Artronic does not knowingly collect any information from children.

Changes to this policy

If this policy changes, the new version will be published on this page with a new date.
