Privacy Policy - Roast Log

Last Updated: November 8, 2026

Overview

Roast Log ("the App") is a home coffee roasting log, published by WittyApps. This policy explains what information the App handles, what stays on your device, and what is shared with service providers. The App works offline and requires no account and no sign-in. The App contains no advertising.

Information We Collect

Stored only on your device (never uploaded):

• Your green bean inventory, roast logs, roast milestones and temperatures, comparisons and cupping notes.
• Your settings, reminder preferences and your Pro subscription status.

Collected automatically (sent to service providers):

• Crash reports (via Google Firebase Crashlytics): technical information such as device model, operating system version, app version and the state of the App when an error occurred.
• Usage analytics (via Google Firebase Analytics): which features are used (for example, starting a roast or exporting a CSV), together with a random app instance identifier and general device information. These events are not linked to your identity and contain no bean names, roast data, notes or other values you enter.

We do not collect your name, email address, phone number, contacts, photos or precise location, or the contents of your roast logs.

How We Use Information

• Crash reports: to find and fix bugs.
• Usage analytics: to understand which features matter and improve the App.
• Cupping reminders are scheduled as local notifications on your device. No push server is used.

We do not sell or share your personal information, and we do not use it for advertising or tracking.

Data Storage

Your beans, roast logs, notes and settings are stored locally on your device only. Deleting the App deletes this data. We operate no servers and hold no copy of your data. CSV files you export are created on your device and shared only where you choose to send them through your device's share sheet. If you use your device's own backup features, your data is handled under your device platform's terms.
