The Android version of the App uses Firebase Crashlytics to help us identify and fix technical problems. If the App crashes or encounters an error, limited diagnostic information is automatically sent to this service, which may include: your device model and manufacturer, your Android OS version, the App’s version, a device installation identifier, and technical details about the error itself (such as a crash stack trace). In a small number of specific error-handling situations, this diagnostic information may also include your account’s internal user identifier — an anonymous string, not your name or email address — solely to help us locate and resolve the specific issue you encountered.
This diagnostic data is used only to identify, diagnose, and fix technical problems with the App. It is not used for advertising, marketing, or user tracking, and it is not sold or shared with third parties beyond the crash-reporting service itself (Google Firebase).
We do not send your email address, your name, or any of your actual garden data (plants, harvests, photos, journal entries, etc.) to this crash-reporting service.
Beyond the limited crash and diagnostic reporting described above, we do not collect your data for advertising or analytics purposes. We do not serve ads. We do not share your garden data with third parties.

Track saved, purchased, traded, and gifted seed lots per variety. Know exactly what's in your seed stash and where it came from.
Export your full season as a 5-tab .xlsx file — plants, harvests, journal entries, heaviest tomatoes, and seed inventory. Opens in Excel, Google Sheets, or any compatible spreadsheet app.
