Logbook Time Calc

Privacy Policy

Last updated: June 24, 2026

Overview

Logbook Time Calc is designed to help pilots calculate flight-time totals from logbook photos. The app does not sell personal data and does not track users across apps or websites.

Data Collection

The app does not require an account, does not include advertising, and does not use third-party tracking tools.

Photos and Recognition

Photos are used to detect, crop, and read logbook tables inside the app workflow. Logbook images and detected values are used only to provide the app's scanning, correction, and calculation features.

The app offers two reading engines. With Local AI (the default), all scanning, handwriting learning, and calculations run entirely on your device; no images or data are sent to our servers or any third party, and an internet connection is not required.

Cloud AI (Optional)

You can optionally switch to Cloud AI for higher accuracy on difficult handwriting. Only when you enable Cloud AI and capture a page, that photo is sent over a secure connection to Google's Gemini API to read the handwritten hours and minutes. The image is used solely to return those values for that single request and is not stored by us. We ask for your consent the first time you turn on Cloud AI. This processing is governed by Google's Privacy Policy (policies.google.com/privacy) and the Google APIs Terms of Service. We do not send any account information, and the data is not used to identify or track you. If you prefer to keep everything on your device, simply use Local AI.

iCloud Backup (Optional)

If you choose to back up logbook pages, the images are stored only in your own private iCloud (iCloud Drive) under your Apple ID. They are accessible only to you; we have no access to them and they are never stored on our servers. Backup is managed by Apple iCloud and governed by Apple's Privacy Policy.

Camera and Photo Permissions

Camera access is used only when you choose to capture a logbook page. If photo access is requested, it is used only for images you select or capture for analysis.

Network and Tracking

Local AI works fully offline. A network connection is used only for optional features: Cloud AI (to read a captured page via Google's Gemini API), iCloud Backup, and in-app purchases handled by Apple. Logbook Time Calc does not use third-party advertising or tracking tools and does not track users across apps or websites.

Children's Privacy

Logbook Time Calc does not knowingly collect personal information from children.
