Timber Measure — Last updated 13 September 2026

Timber Measure is an iPhone app for measuring timber: log diameters, stacked roundwood and firewood, and brush piles (bundle identifier lv.timbermeasure.app). This page explains what happens to your information when you use it.

The short version: everything stays on your iPhone.

1. We do not collect any data

Timber Measure has no user accounts, no servers and no back end. The app never sends your information anywhere. Specifically:

We do not ask for, or receive, your name, email address or phone number.
There is no sign-up, no login and no password.
There are no analytics, no crash reporting, no advertising and no tracking of any kind.
There are no third-party SDKs that collect information about you.
The app does not read your advertising identifier, contacts, location, health data or microphone.

This is why the App Store privacy label for Timber Measure says Data Not Collected.

2. Camera and LiDAR

The app asks for camera permission because measuring works by pointing the camera (and, on iPhone Pro models, the LiDAR scanner) at a pile of logs. The camera image and the LiDAR depth data are processed entirely on the device — by an on-device machine-learning model that finds log ends, and by Apple's ARKit. No image, frame or depth data is uploaded, stored on a server, or shared with anyone. Frames are discarded as soon as the measurement is computed.

If you choose a photo from your photo library, the app only receives the single image you pick (Apple's picker), processes it on the device, and does not keep it.

3. What the app stores on your device

So that you can look back at earlier measurements, the app keeps a history in its own private storage on your iPhone. It never leaves the device and is not readable by other apps.

What	Why
Your saved measurements (dimensions, diameters, coefficients, computed volumes, date, optional note)	The History tab
Your settings (country/standard, default log length, default coefficient, marker size)	So you don't re-enter them each time

To delete everything: use "Delete all" in History, or delete the app — iOS removes its storage with it. There is no copy anywhere else.

4. Accuracy notice

Volumes are estimates computed from measurements and standard conversion coefficients (for example, stacking and packing factors). Results marked with ≈ are approximations. Timber Measure is a field aid and does not replace legally certified measurement where such is required.

5. Changes to this policy

If a future version of the app ever handles information differently, this page will be updated before that version is released, and the date at the top will change.
