A cake that won't scan, a question, or something broken: write to support@sevenshelves.example. Include your phone model and what you were doing; a photo of the wrapper helps.
How does scanning work?
Seven Shelves reads the printed text on a wrapper (Chinese and English), such as the factory, the recipe number and the year, and matches it against its catalog of teas. When it isn't sure, it shows three guesses. When a wrapper has no readable text, it keeps your photo and asks who made it.
Can I use it on a computer?
Yes, for browsing your shelf and importing a spreadsheet. In the app, open Settings and tap “Use Seven Shelves on the web”, then sign in with the code it shows.
How do I get my data out?
Export your shelf as a CSV spreadsheet from Settings in the app, or from your shelf on the web. Export is free on every plan.
How do I delete my account?
See Delete your account.
