App: Capybara Court, listed in Korean as
카피바라 법원 (package com.tinygavel.tiny_gavel)

Capybara Court is two rooms under one roof. In the private court, two partners each write their side of a small dispute and an AI judge issues a lighthearted ruling that only they see. In the public gallery, one person can publish a story anonymously, get the same judge's first read of it, and hear what strangers would say. This page says exactly what the app stores in each room, for how long, and who can see it.
The short version of the difference: nothing in the private court is ever shown to anyone but the two people in it. In the public gallery you decide, story by story, what strangers see — and once something is published, other people can read it, answer it and pass the link on.
What we collect
- Your testimony — the answers you type to the four case questions.
- Names — the names or nicknames you choose for the two of you. They appear on your rulings.
- Case details — a case title generated from your words, filing time, an optional hearing time, and your app language.
- An anonymous ID — created by Firebase Authentication. No account, email, phone number, or password is ever collected.
- A push token — only if you allow notifications, so the verdict can reach you.
And, only if you use the public gallery:
- Your story — what you write, kept in two separate places: the original, which only you and the judging service can reach, and a masked version for publication.
- A per-story alias — a nickname the server issues, like "Quiet Otter". It is not derived from your ID and cannot be traced back to it by other readers.
- Answers you leave — comments and replies under other people's stories, shown under an alias.
- Marks and reports — which reaction you left on a story, visible to nobody but you, and any report you file.
- Aliases you have silenced, so they stay silenced.
The seal
Your testimony is sealed by database rules, not by promise: your partner's device is refused permission to read your words, and yours is refused theirs. The only reader of both sides is the judging service that writes the ruling.
A story you publish is sealed the same way, in a different direction. What you typed is stored where no other reader has permission to open it. What strangers see is a separate, masked copy that the server writes — so a story published as "verdict only" is not a hidden field that a clever request could ask for. The text is simply not in the document anyone else can read.
What other people can see
You choose this for every story, and the default is the quietest one:
- Just for me — nobody else can open it at all.
- Anyone with the link — only people you hand the link to.
- The gallery — it appears in the public feed.
- The verdict only (the default) — your story is judged, but only the judge's reading is published. Your words are not.
Before anything is published, names, phone numbers, email addresses, account handles, workplaces and schools are removed automatically, and you are shown the masked version to check and edit before it goes out. Automatic masking is careful but not perfect: please read what you are about to publish. You can narrow a story's reach or delete it at any time. Reach only ever narrows: a story can be made quieter later, never louder, because everyone who could already read it has.
How it is used
Testimony and stories are sent to Google's Vertex AI (Gemini) to produce a ruling, to mask personal details, and to check for content that must not be published. They are not used to train models, not sold, and not shared with advertisers. The app contains no ads and no analytics trackers.
Reporting, and when a person reads something
Anything published in the gallery — a story or an answer — can be reported by any reader, and enough reports put it in front of a person sooner. Nothing is hidden by a count: an unpopular story would otherwise be a takedown that costs three installs. Reported content is read by a person: the developer named at the top of this page, and only that person can take something down. That is the one case in which a human being reads what you wrote, and it exists because a public room without it is not a safe one. The report itself is not readable by anyone else, and the author of a reported story is never told who reported them.
You can also silence an alias, which hides that voice from you without telling them.
Some stories are never given a public verdict at all. When a story involves harm to yourself or someone else, abuse, or an urgent medical or legal situation, the app answers with professional resources for your region instead of a ruling, and does not publish it. Cappy is a cartoon capybara, not a lawyer, doctor or counsellor, and the app never claims otherwise.
How long it lives
Every case shreds itself 30 days after filing: testimony, ruling, title, and names are permanently deleted from our servers on a daily schedule. If you want to keep a ruling, export the card before then. Withdrawing a case discards its testimony immediately.
Stories work the same way, counted from the server's clock rather than your phone's: 30 days after publication a story, its verdict, every answer under it and every mark on it are deleted together. You can delete your own story before then, at any time, and a shared link stops working when the story goes.
Where it lives
Data is stored in Google Cloud (Firebase Firestore, United States) and encrypted in transit. Google acts as our processor, and no other company receives your data. What you publish in the gallery is, of course, visible to the other people using the app — that is what publishing is, and it is the only sense in which anything you write goes further than Google and us.
Your choices
- Notifications are optional and asked for in context.
- Uninstalling the app abandons your anonymous ID; any remaining cases and stories still shred on their 30-day schedule.
- You can delete any story you published at any time, and narrow who can see it at any time. Narrowing is the only direction: widening would hand your words to people you never chose, so the database refuses it.
- Your anonymous ID lives on this phone. Reinstalling gives you a new one, which means the app can no longer show you the stories you wrote before. That is the price of publishing under no account, and we would rather pay it than ask you for one.
- For an earlier deletion or any question, write to us and include your case number.
Age
Capybara Court is for ages 13 and up, and the public gallery is meant for adults: what you publish there goes to strangers.
The app does not verify anyone's age and never asks for a birth date. What it does ask, before your first story, is that you agree to the gallery's rules, which cover what may not be posted and how to report it.
