Fishdoku Privacy Policy

Last updated: November 10, 2026

Fishdoku is a fishing puzzle game. This page explains what information the game uses and why. In short: the game works fully offline. It only sends your game data off your device if you choose to sign in, the anonymous gameplay stats described below can be turned off, and the only ads are optional ones you choose to watch for a bonus.

Without signing in

Your progress (your catches, coins, settings, aquarium and so on) is saved only on your device. Nothing is sent to us or to anyone else. Uninstalling the game deletes it.

If you sign in with Google (optional)

Signing in lets you back up your progress and appear on the leaderboards. It uses Google Firebase (Firebase Authentication and Cloud Firestore), run by Google. When you sign in:

• Your Google account's name, email address and a user ID are handled by Firebase Authentication so the game knows which save is yours. Your Google name and email are never shown to other players.
• An angler name. When you first sign in, the game gives you a random angler name (like "Salty Pike 42"), which you can change. This is the only name other players see. Names have to follow simple rules (no rude words, links or pretending to be us), and we may change or remove a name that breaks them.
• A profile picture: one of the fish you've caught, which you pick. Other players see it next to your angler name.
• A copy of your game save is stored in Cloud Firestore, linked to that user ID. Only you can read or change it.
• Leaderboard entries (your biggest catches, Daily Pond times, Weekly Tournament scores and your weekly "Biggest Haul" total weight) are stored with your angler name, your picture and the nameplate style you picked. Other signed-in players can see these entries.
• A player profile: your angler name and picture, angler title, total weight caught, number of catches and species, your five heaviest catches, and how your dock looks (your angler character and outfit colors, hat, rod, pet and its accessories, and the decorations on your dock). Signed-in players can see it (it's what friends see when they tap your name), and your total is used to show your rank among all players and the weekly total for everyone together.
• Your friend code and friends list. Your code lets friends add you. The friends you add are kept in your save.
• Reports. If you report another player's name, we receive their angler name and user ID and yours, so we can look into it. Hiding a player happens only on your phone.

Your email address is never shown to other players. Google's own privacy policy covers how Google processes sign-in data: policies.google.com/privacy.

Error reports (optional, off unless you turn them on)

If you turn on Send error reports in Settings, the game sends us a short note when something goes wrong: the error message, the game version and your phone model. It contains no name, account or save data, and isn't linked to you. We use it only to fix bugs.

Gameplay stats (optional, you can turn them off)

The Android app sends anonymous gameplay moments through Google's Firebase Analytics: which screens you open, starting, winning or losing a pond (its size, twist, the fish's rarity, time, hints and mistakes), using a hint or a fishing tool, buying something in the Tackle Shop, tutorial steps, opening a new fishing spot, choices on the game's one-time offers (like the reminder or the sign-in), feeding the aquarium, and how many fish you've caught so far. Firebase also records basic app usage, like when the app opens, along with a random app-install ID, your phone model, Android version and rough country. None of it includes your name, email or save, and we use it only to see where players get stuck so we can improve the game. Turn it off any time in Settings › Help & privacy › Share gameplay stats.

Purchases

Purchases (like the Fishing Pass) are made through Google Play. We never see your card or payment details. To check and restore what you've bought, the game uses RevenueCat, a purchase service, which receives a random app user ID, the purchase record from Google Play (what was bought, when, its price and currency, and a purchase token), your rough country, and your phone model and Android version. It doesn't receive your name or email. RevenueCat's privacy policy: revenuecat.com/privacy.

Optional ads

Some bonuses (like double coins from a catch) can be earned by choosing to watch a short ad. Ads never play on their own or in the middle of a pond, and with the season's Fishing Pass the bonuses come without the ad. The ads come from Google AdMob. When an ad loads, AdMob receives your phone's advertising ID, your IP address (and the rough location it suggests), your phone model and Android version, and how you interact with the ad. It uses these to show the ad, count it, prevent fraud and, where you allow it, choose ads that suit you. In the European Economic Area, the UK and Switzerland, Google's consent message asks for your choice first. You can change it any time in Settings › Help & privacy › Ad choices. Anywhere, you can reset your advertising ID or stop personalised ads in your phone's settings (Settings › Privacy › Ads on most Android phones). How Google uses this information: policies.google.com/technologies/partner-sites.

What we don't do

• No forced ads. The only ads are the optional ones above, and the advertising ID goes only to AdMob for them. Our gameplay stats and error reports never use it.
• No selling of your information. Apart from the services named on this page (Google Firebase, Google AdMob and RevenueCat), we don't share it with anyone.
• No location, contacts, camera, microphone or files are accessed.

Permissions

The Android app asks for INTERNET (for the optional cloud saves and leaderboards, purchases and the optional ads), BILLING (to buy through Google Play), AD_ID and Android's ad-services permissions (used only by AdMob for the optional ads) and VIBRATE (for haptic feedback, which you can turn off in Settings). If you turn on the optional daily reminder, it also asks to show notifications, and uses RECEIVE_BOOT_COMPLETED so the reminder survives a restart. The reminder is set on your phone; nothing is sent anywhere.

Deleting your data

You can delete your cloud data yourself in the game: Settings › Cloud save › Delete my cloud data. It removes your cloud save, profile, friend code and leaderboard entries, and your sign-in. You can also ask us by email; see fishdoku-5615a.web.app/delete. Progress saved only on your device is deleted when you uninstall the game.

Children

Fishdoku is not directed at children under 13, and we don't knowingly collect personal information from them.

Changes

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