Terms of Service
Last updated 13 August 2026. The Privacy Policy follows below.
Who provides the game
Tiny Aquarium is made and operated by Lunheim Studios, Germany. These terms cover the game on Google Play, the App Store and Steam. You can reach us any time at contact@lunheimstudios.com.
Lunheim Studios, Pacelliallee 20, 36043 Fulda, Germany
Your account
You sign in through Steam, Google or Apple. There is no separate registration and no password to remember — your platform account is your identity, and the only thing we store from it is the account identifier that platform gives us.
You are responsible for what happens on your account, so keep your platform sign-in secure.
Rules of conduct
Tiny Aquarium is a shared space. Playing here means:
- No cheating, tampering with the game client, or manipulating game data
- No offensive or abusive usernames
- No abusive behaviour toward other players — you can report anyone in-game
- No manipulation of the fish market
Enforcement
We review player reports and act on them. Where an account breaks the rules, we may:
- Suspend it temporarily, with a stated reason and an expiry time
- Suspend it permanently
- Restrict access to individual features rather than the whole game
- Reduce how visible its content is to other players
We keep a record of suspensions and restrictions even after an account is deleted. It is what stops a suspension being sidestepped by starting over, and it is how the game stays fair for everyone else playing.
What you create
Your aquariums are yours. When you publish one, choose a username, or react to someone else's tank, you are making that visible to other players, and you give us the licence we need to display it in the game and show it to them. We may remove content that breaks the rules above.
Virtual items and currency
Shells, pearls and coins are in-game currency. They have no real-world value, cannot be exchanged for money, and cannot be moved outside the game. Fish, decorations and other items are a licence to use them in-game, not property you own.
The fish market is player-to-player and runs on in-game currency only. We may adjust balances and prices, and items may change or be removed as the game develops.
Availability
The game runs on our servers, and maintenance sometimes takes it offline. We don't guarantee uptime, and we may change or discontinue the service.
Ending the relationship
You can delete your account from inside the game at any time — open Settings and tap Delete progress. It takes effect straight away and can't be undone. There is also a request page if you can't sign in.
We may suspend or terminate accounts that break these terms.
Liability
We are liable without limitation for damage caused intentionally or by gross negligence, for injury to life, body or health, and wherever German law otherwise requires it, including under the Produkthaftungsgesetz. For slight negligence, we are liable only where an obligation essential to the contract is breached, and only for the damage typically foreseeable in this kind of agreement. Beyond that, the game is provided as it is, and we don't warrant that it will be uninterrupted or error-free. Your statutory rights as a consumer are unaffected.
Governing law
German law applies. If you are a consumer, this does not deprive you of the protection of mandatory law in the country where you live.
Changes to these terms
If we change these terms, we update this page and change the date at the top. Where a change materially affects you, we tell you in-game before it takes effect. Carrying on playing after that means you accept the new version.
Legal notices

Privacy Policy
This explains what Tiny Aquarium collects, why, how long we keep it, and how to get rid of it. It covers the game on Google Play, the App Store and Steam. Last updated 13 August 2026.
Who we are
Tiny Aquarium is made by Lunheim Studios, Germany. We are the controller for the data described here. You can reach us any time at contact@lunheimstudios.com.
Lunheim Studios, Pacelliallee 20, 36043 Fulda, Germany
What we collect
Your account. When you sign in through Steam, Google or Apple, we store the account identifier that platform gives us. We never receive or store your email address, your real name, or your password.
Your profile and game data. The username you choose, your aquariums and everything in them, your shells, pearls and coins, your experience, your friends list, aquariums you publish, reactions you give, reports you file, and the in-game mail you receive.
How you use the game. Which panels and features you open, when a session starts, when you sign in, what you buy and earn with in-game currency, how far you get in the tutorial, and your activity on the fish market. Each is stored with your account identifier, a session identifier, the app version and the platform you play on.
Crashes. When the game hits an error, we record the error message and the stack trace, along with the app version and platform, so we can fix it.
Keeping the game fair. We record the results of automated integrity checks on your game session, so that everyone is playing the same game.
We do not collect your real name, email address, postal address, phone number, location, contacts, photos, or any advertising identifier. There are no ads in Tiny Aquarium.
Why we collect it
- To run your account and the game itself — necessary to provide what you signed up for (Art. 6(1)(b) GDPR).
- To understand how the game is used and to fix crashes — our legitimate interest in maintaining and improving our own game (Art. 6(1)(f) GDPR).
- To keep the game fair, handle reports, and enforce the rules — our legitimate interest (Art. 6(1)(f) GDPR).
Who we share it with
Nobody. We do not sell your data, we do not share it with advertisers, ad networks, analytics companies or data brokers, and there are no third-party tracking SDKs in the game. Everything above goes to our own servers and stays there.
Our servers and database are hosted with Supabase, which acts as our processor under a data processing agreement and stores the data on AWS infrastructure in the EU (eu-central-1, Frankfurt). Supabase handles the infrastructure — it does not use your data for anything of its own.
Signing in goes through Steam, Google or Apple, and their own privacy policies cover what they do on their side. And anything you choose to make public in the game — your username, aquariums you publish, reactions you give — is visible to other players, which is the point of it.
How long we keep it
- Your account and game data: until you delete your account.
- Individual usage and crash records: 30 days. After that they are rolled into daily totals not linked to you or any individual player, and the individual records are deleted.
- Enforcement records: if an account has been suspended or restricted, we keep that record even after the account is deleted. This is what stops a suspension being sidestepped by starting over, and it protects everyone else playing.
Deleting your account
You can delete your account from inside the game — open Settings and tap Delete progress. It takes effect immediately and cannot be undone. If you can't sign in, there is a request page.
Deleting removes your account, your aquariums and everything in them, your published aquariums, your friends list, your in-game mail, your usage and crash records, and your integrity records. Enforcement records are the one exception, as described above. Your progress and anything you bought cannot be restored afterwards.
Your rights
You can ask us for a copy of the data we hold about you, ask us to correct it, ask us to delete it, ask us to restrict or stop processing it, or ask for it in a portable form. Email contact@lunheimstudios.com and we will handle it. You also have the right to complain to a data protection supervisory authority in your country.
Children
Tiny Aquarium is not directed at children under 13, and we do not knowingly collect data from them. If you believe a child has created an account, email us and we will delete it.
Security
All traffic between the game and our servers is encrypted in transit.
Changes to this policy
If we change what we collect or what we do with it, we will update this page and change the date at the top.
