Privacy policy

Tankt is a cozy aquarium game, and we want your data to be as calm as your tank. This page explains what the game collects, why, who can see it, and how to remove it. We've tried to keep it short and in plain language.

What we collect

Your game, on your device

Your tanks, creatures, coins, settings and progress are saved on your phone or tablet. You can play the whole aquarium without an internet connection.

Your keeper account

When you're online, Tankt creates a cloud account for you automatically so your progress is backed up and friends can find your tanks. It holds:

• A random install ID that the game generates when it's first opened. It isn't your Apple ID, your Google account, your device's advertising ID or anything that identifies you personally. It just lets the game recognise your account.
• Your keeper name (it starts as "Keeper" and you can change it) and your friend code, a random eight-character code.
• A backup of your game: your tanks, creatures (names, species and genes), plants, decorations and items.
• Unlocks, such as rewards from promo codes you've redeemed.

Game Center and Google Play Games (optional)

If you're signed in to Apple Game Center on iPhone or iPad, or Google Play Games on Android, Tankt can link it to your keeper account so you can restore your account on a new device. We receive the player ID that Apple or Google gives Tankt and your gamer nickname, and they confirm the link is really you. We don't get your Apple ID, Google account, email address or gaming friends list. Linking is optional, and the game works fine without it.

Friends and activity

• Your list of friends.
• The tanks you share with friends, so they can visit them.
• Things friends do for each other: pets, likes, "Feed fish" and "Tidy tank" helping hands, and short notes (up to 180 characters) left on a tank or creature.
• Your activity feed, so you can see who visited and whether you've read it yet.

Notifications

If you allow notifications, Apple or Google gives the game a push token so we can let you know when a friend visits, likes, pets or leaves a note. Reminders about your tank (like "your fish are hungry") are scheduled on your device and don't involve our servers.

Purchases

If you buy something in the game, the App Store (on iPhone and iPad) or Google Play (on Android) handles the payment. We never see your card or payment details. We only receive confirmation of what was bought so we can deliver it.

Basic technical information

Like almost every online service, our servers briefly keep standard logs, such as IP address, time and the request made. We use them to keep the game running, stop abuse and fix bugs, not to build a profile of you.

Things we don't collect

We don't ask for or collect your email address, phone number, real name, birthday, contacts, photos, camera, microphone or location. Tankt doesn't include advertising or analytics tools, and it doesn't use your device's advertising identifier.

How we use it

• To run the game and back up your progress.
• To power friend features: visits, helping hands, likes, pets and notes.
• To send notifications you've agreed to.
• To deliver purchases, promo code rewards and unlocks.
• To keep Tankt safe, handle reports and fix problems.

That's it. We don't use your information for advertising or to build profiles, and we don't sell it or share it for advertising.

Who can see what

People with your friend code

Entering someone's friend code adds you as friends straight away. Only share your code with people you know, like friends and family.

Your friends

Friends can see your keeper name, your friend code and the tanks you share, including creature names, plants and decorations. They can visit, help out, and leave likes, pets and notes.

Notes you leave

A note you leave on a friend's tank can be seen by that friend and by their other friends when they visit, along with your keeper name. You can delete your own notes at any time, and they disappear for everyone.

Everyone else

Nobody else. Tankt has no public profiles, no search by name, no leaderboards that show your name and no chat with strangers.

Companies that help us run Tankt

A small number of service providers handle data for us, only to provide their service:

• Supabase hosts our database and servers.
• Apple provides Game Center, push notifications and App Store purchases on iPhone and iPad.
• Google provides Google Play Games, push notifications and Google Play purchases on Android.
• Amazon Web Services hosts this website.

When the law requires it

We may share information if the law requires it, or if we believe it's needed to protect someone's safety. If Tankt is ever sold or merged, this policy will continue to protect your information.

Kids and families

Tankt is made for everyone, and we know younger players enjoy it too. That's why the game is designed to collect as little as possible:

• No ads, no tracking and no data sales.
• No email, phone number, real name or birthday is ever requested.
• No public profiles, no search and no chat with strangers. Players can only connect through a friend code they choose to share.
• Notes are short and friends-only. Players can remove friends and delete their notes at any time.

The random install ID is used only to run the game: signing in, saving progress and keeping the service secure. We don't knowingly collect other personal information from children under 13 (or the minimum age where you live). Because keeper names and notes are typed by players, we encourage kids to use a made-up keeper name and to never put personal details such as their full name, school, address, phone number or social media handles in a note.

For parents and guardians: you can ask us to review or delete your child's account and everything in it by emailing tanktapp@gmail.com with the keeper name and friend code shown on the Friends screen. We'll take care of it promptly. Apple'sparental controls andAsk to Buy, and Google'sFamily Link on Android, can also limit notifications and purchases.

Keeping your data safe

Information sent between the game and our servers is encrypted in transit. Our database uses access rules so each player can reach only their own data and what their friends have shared with them, and only the people who run Tankt can access it for support. No system is perfect, but we work to protect your information and will let you know if something goes wrong that affects you.

How long we keep it

• Your keeper account and backup are kept while you use Tankt.
• Helping hands from friends expire after seven days if they aren't collected.
• Notes you delete are hidden for everyone right away.
• When your account is deleted, your profile, backup, friends list, shared tanks, notes, likes and notification tokens are deleted with it. Server logs and backups roll off on their own schedule shortly after.

Your choices

• Change your keeper name at any time in the game.
• Remove a friend from the Friends screen. They'll no longer see your tanks.
• Delete a note you wrote.
• Turn notifications off in your device's Settings.
• Skip Game Center or Google Play Games. Linking them is optional.
• Delete your account, or get a copy of your data, by emailingtanktapp@gmail.com with your keeper name and friend code. Deleting the app removes your local save, but not your cloud account, so please get in touch if you'd like that removed too.

Depending on where you live (for example, the EU, the UK or California), you may have legal rights to access, correct, delete or move your data, or to object to how it's used. We honour these requests for everyone, wherever you live. We use your information to provide the game you asked for, to keep it safe (our legitimate interest) and, for notifications, with your permission. If you have concerns, you can also contact your local data protection authority.

Where your data lives

Tankt is run from the United States, and our service providers may store data in the United States or other countries. Wherever it's stored, we protect it as described here.

This website

tankt.app doesn't use cookies, analytics or advertising. Our web host keeps standard server logs to deliver pages and prevent abuse.

Changes to this policy

If Tankt changes, this policy may too. We'll update the date at the top, and if a change is significant, we'll let you know in the game before it takes effect.
