Please do not send passwords, authentication codes, payment card numbers, or AI provider API keys. Even when needed for investigation, keep personal information to a minimum.
Before you write
Nyashiki runs entirely on your device. There is no account and no sign-in, and receipt images, household data, and learning data are all stored on your iPhone. Because the operator never receives that data, we cannot look inside it or restore it for you.
When reporting a problem, the following details help us investigate.
Your Nyashiki app version
Device name and iOS version
What happened, and what you did just before it
Any error message shown
A screenshot showing the problem
Before sending a screenshot, please check that it does not include unnecessary personal information such as your name, address, or card numbers.
Frequently asked questions
The receipt was read incorrectly
Recognition results are reference information meant to support your own review. On the confirmation screen shown before saving, you can correct items, quantities, amounts, and the date.
Accuracy improves when the whole receipt is inside the frame in a well-lit place, without shadows or folds. If you would like us to improve a case, tell us when it happened, your device, the kind of store, what was shown, and what you expected.
I want to correct a word's meaning or reading
You can change these on the word edit screen. If you cannot correct it there, send us the word, what you expected, and what was actually shown.
What do I need in order to use the AI features?
Nyashiki's core features work without AI. Receipts are read with on-device text recognition and local parsing, and word meanings come from a bundled dictionary, so the app works as-is with no setup.
To use the AI features (assisted receipt structuring, word explanations, image generation), register your own AI provider API key under Profile → AI. Nyashiki does not include an API key belonging to the operator. Any provider fees arise between you and that provider.
Where is my API key stored?
It is stored in the device Keychain and is never sent anywhere other than the endpoint of the provider you selected. You can delete it from the settings screen at any time.
I want to delete my data
Receipts, household data, learning data, images, and AI settings can each be deleted from the corresponding feature in the app. Deleting Nyashiki from your device also removes the information stored inside the app.
The operator keeps no copy, so nothing can be restored after deletion. Consider exporting a backup before deleting anything you may need.
I am changing devices. Can I move my data?
Export a file with the app's backup feature and load it on the new device. The backup is encrypted with a key derived from the passphrase you set. If the passphrase is lost, no one, including the operator, can decrypt it.
Does it cost anything?
Nyashiki is free, with no in-app purchases and no subscriptions. The only cost is the provider usage fee if you choose to use the AI features, which arises between you and that provider.
