Privacy Policy

In short

There is no account, no advertising and no analytics. One feature sends your data off your device: the sign translator. (Purchases are checked with the App Store or Google Play — see below.) This page explains exactly what it sends and what it does not.

Translating a photo

When you take or choose a photo and tap analyse, the image is sent over an encrypted connection, through our relay server (which passes it on without keeping it), to Anthropic's Claude API, which reads the characters and returns a translation. Apart from asking the App Store or Google Play about purchases, that is the only time the app talks to a server. We do not keep a copy of your photo, and the app does not save it. Anthropic processes it to produce the answer under their API terms.

What stays on your device

The language you chose and whether you have unlocked the guide (so the app opens without waiting for the store). That is all. Photos you take in the app are not gathered by us, and deleting the app removes everything it kept.

What the app never does

It does not create an account or ask for your email. It contains no analytics or crash-reporting SDK. It shows no ads. It does not read your contacts, location or calendar.

Purchases

The app is unlocked with a single one-time in-app purchase (¥480 in Japan; the price in your country is shown in the app before you buy). It is not a subscription and is never charged again. Payment is handled entirely by the App Store (Apple) or Google Play (Google) — we never see your card or payment details, and no account with us is needed. The app asks the store only whether this Apple ID or Google account owns the guide. On iPhone, it also reads Apple's signed record of when you first got the app, so people who bought it while it was a paid app keep full access without paying again. People who started the earlier monthly plan keep full access while it is active and can cancel it at any time in their store's subscription settings. On a new device, use Restore Purchases in the app.

Camera and photo access

The app asks for camera and photo access only so you can pick the picture you want translated. It never opens either on its own.

A word of care

Whatever is in the photo you choose is sent for reading. Please avoid photographing people, documents or anything private that you would not want processed.

This website

Static pages, no cookies, no tracking scripts. The host keeps ordinary server logs for security and traffic counting.

Children

The guide is suitable for all ages. Nothing is collected about anyone, children included.

Changes

If the app ever starts collecting something, this page will say so before that version ships.

Contact

Through the support channel on the App Store listing.
