Your data
What you record stays yours. You let us keep and use it to run Fishfolk, as the privacy notice explains, and you can delete it at any time.
Terms
Last updated: 10 November 2026
The short version: Fishfolk gives guidance, you look after your animals, and what you record stays yours.
About these terms
These terms cover your use of Fishfolk, which Luis Varela runs. Creating an account means accepting them. Questions go to support@fishfolk.app.
What Fishfolk is
Fishfolk helps you keep an aquarium: it records your tanks and checks your stock against our species data. It is free.
Guidance, not a guarantee
Fishfolk's ranges and checks are compiled with care, but they can be incomplete or wrong. They are guidance, not veterinary advice. You remain responsible for your animals.
Not legal advice
The legal minimums shown for your tanks and the legal rules on species pages are information we compiled from laws and official lists. They are not legal advice.
They can be incomplete or out of date, and they cover only some countries and regions. Rules can also differ by region or municipality, and some species need a permit.
Before you rely on them, check with the authorities where you keep your animals, or ask a lawyer. Following the law there remains your responsibility. If a rule looks wrong, report it from the species' page.
Your account
Use an email that is yours, and keep the email and the passkeys that sign you in to yourself. An account is for one person, who must be at least 13 or have a parent's consent.
Fair use
- Don't try to break or overload Fishfolk, or to reach other people's data.
- Don't put anyone's personal details in a tank's name: a shared link shows it.
- The species pages are for reading: don't copy the catalogue wholesale for another service.
Changes to Fishfolk
We improve and change Fishfolk and may stop features. We aim to keep it running, but cannot promise it is always available or free of errors.
Ending
You can delete your account at any time in Your account. We may suspend an account that breaks these terms, and will tell you why unless the law prevents it.
Liability
As far as the law allows, we are not liable for indirect losses, or for losses from following or not following Fishfolk's guidance, including the loss of animals. Nothing in these terms limits your rights as a consumer, or any liability the law does not allow us to limit.
Law
Portuguese law governs these terms. If you live elsewhere in the EU, you keep the protection of your own country's consumer law and may bring a claim in its courts.
Changes to these terms
We announce changes to these terms on this page, with the date of the change at the top. Corrections, and changes that do not affect you, take effect at once.
An important change, one that reduces your rights or adds to your obligations, takes effect 30 days after we announce it. If you do not agree with it, you can delete your account before then.
