FAQ
This public site only describes capabilities that are verified in the app and supporting documentation.
BrewTinker works as a fully local app by default. Signing in and enabling sync is optional.
The current supported device families are Acaia scales, Timemore scales, and Inkbird thermometers. Actual compatibility can still vary by model, firmware, and iOS environment.
When sync is enabled, brew records, beans, recipes, and equipment sync through Firebase Firestore. Bean images can also be uploaded to Cloudflare R2 through a secure proxy.
Analytics is opt-in and off by default. Crash reporting is on by default but can be disabled at any time in Settings → Privacy.
You can export individual brews as text, PDF, image, or JSON, and batch export brew history as CSV, JSON, or text.
BrewTinker currently supports English, Simplified Chinese, Japanese, Korean, and German.
