Privacy Policy for GrainLog (dev.emberforge.grainlog)

Last updated: November 2, 2026

GrainLog is a film photography logging app for 35mm and 120 format photographers, published under the package name dev.emberforge.grainlog. This policy describes exactly what data the app collects, how it is used, and how to reach us. Questions should be directed to kat5nryn1hru@gmail.com.

WHAT WE COLLECT

GrainLog sends data to a server operated by the developer over an encrypted HTTPS connection. Three types of information are collected automatically while you use the app:

App activity: which screens you open, how long you spend on each one, the length of each session, and specific in-app actions such as creating a new roll, logging a frame, or advancing a roll's status. This data is collected every time you use the app and cannot be switched off.

App diagnostics: your device model, Android OS version, GrainLog app version, and the category of any handled in-app errors. No error message text is ever sent — only the type of error. The developer uses this to find and fix problems.

A random installation ID: a randomly generated identifier created the first time you launch GrainLog. It is stored on the developer's server and used only to count distinct installations. It is not linked to your name, Google account, or advertising profile. It is permanently deleted from our server when you uninstall GrainLog.

GrainLog does not collect your name, email address, physical location, contacts, photos, or any text you type into roll names, frame notes, or lab entries. No camera access is requested or used.

HOW WE USE IT

All collected data is used for analytics only: to understand which features are used, how frequently the app is opened, and where technical errors occur. The developer uses this information to improve GrainLog over time. The data is never used for advertising, profiling, or resale, and it is never used to identify you as an individual.

SHARING

GrainLog does not share any collected data with third parties. No advertising networks, attribution services, push notification providers, or external analytics platforms receive any data from this app. All information flows exclusively to a server the GrainLog developer operates and controls.

CHILDREN'S PRIVACY

GrainLog is not directed at children under 13. We do not knowingly collect information from anyone under 13.

CHANGES

We may update this policy from time to time. Material changes will be posted at the URL linked from GrainLog's Google Play listing.
