Privacy Policy

Last updated: September 28, 2026

Short version: your register stays on your phone. We don't collect it, we can't see it, and we don't run a server that could hold it.

What Tijori stores, and where

Everything you enter is stored only in the app's private storage on your device: pieces, weights, hallmarks, bills, people, sets and photos taken in the app. Other apps can't read that storage.

No account, no server, no tracking

• Tijori doesn't ask for an email, phone number or any sign-up.
• The app has no analytics, advertising or crash-reporting SDK that sends your data to us or to third parties.
• We don't operate any server that receives your register.

Backups

Tijori is deliberately excluded from Android's automatic cloud backup and device-to-device transfer, so your register isn't copied into a Google account. As a result, if you uninstall the app, clear its data or lose your device, the register can't be recovered. We are working on a backup feature that saves your register and photos to a place you choose. This policy will be updated before it ships.

Permissions

• Camera (optional): when you tap to photograph a piece, hallmark or bill, Tijori opens your phone's camera, and the photo is saved straight into Tijori's private storage, not your gallery.
• Photos / media (optional): used only when you choose to attach an existing photo, through the system photo picker.
• Biometrics / device credential (optional): used to lock the app. Your fingerprint or face data is handled by Android and never reaches Tijori.

The current app has no internet permission and makes no network connections at all. If a future version fetches public reference data, such as updated safe-harbor figures, it will not send any of your data, and this policy will be updated first.

This website

tijori.zenkasu.com is a static website. It sets no cookies and uses no analytics or third-party trackers. The calculators on the Tools page run entirely in your browser, and nothing you type into them is sent or saved. Our hosting provider may keep standard server logs such as IP address and pages requested for security and operations.

Children

Tijori doesn't collect personal information from anyone, including children.

Changes

If this policy changes, the new version will be posted here with a new "Last updated" date. Any change affecting where your data goes, such as a backup feature, will be described here before it's released.
