Privacy Policy

Last updated: November 13, 2026

Teire is a bonsai care journal that works entirely offline. This page explains, in plain terms, what the app does and does not do with your information.

The short version

No account No server No tracking No ads

Teire does not collect, transmit, sell, or share any personal data. Everything you enter — your trees, their care history, your photos, your balcony and calendar settings — stays only on your device. There is nothing for us to see, because nothing ever leaves your phone.

What Teire stores, and where

Tree records, care log, wiring log, species calendars, balcony settings — saved in a local database inside the app's own storage on your device.
Photos you add — chosen through the system photo picker or taken with the camera, and saved inside the app's own storage. They are never uploaded anywhere.
App preferences (theme, haptics on/off, how many times you've logged care) — saved locally using Apple's standard UserDefaults mechanism, used only to remember your settings between launches.
Reminders — scheduled locally on your device with Apple's notification system. No reminder data is sent to any server, because there is no server.

Camera and photo permissions

Teire asks for camera access only when you choose to photograph a tree for its photo timeline, and for photo-library access only when you choose to pick an existing photo. If you'd rather save a card image to your library, Teire asks for add-only permission at that moment. You can change any of these choices at any time in the Settings app. Declining a permission simply disables the related feature — the rest of the app keeps working.

No analytics, no advertising, no third parties

Teire does not include any analytics, advertising, or crash-reporting software development kit. No identifiers are generated or shared. No data about your usage of the app is sent to Apple, to us, or to anyone else.

Children's privacy

Teire is a general-audience gardening and record-keeping tool. It does not knowingly collect personal information from anyone, including children, because it does not collect personal information from anyone at all.

Changes to this policy

If Teire ever changes what it collects, this page will be updated first, and the "Last updated" date above will change accordingly. Because the app currently has no network connection of any kind, you can always verify these claims by checking your device's own network activity.
