1.Before you write

Two things make a bug report far easier to act on, and both are things only you can see:

• What you did, and what happened instead. "Search finds nothing for X" is fixable. "It's broken" usually is not.
• Your device and OS version, and the app version from Settings.

Please do not send screenshots of your diary unless you want to. Your entries are health data, they never leave your device on their own, and nothing about supporting you requires me to see them.

2.Read this before you reinstall or change phones

This is the honest trade-off of a fully offline app, and it is worth stating plainly rather than burying: privacy of this kind and automatic cloud backup are mutually exclusive. You are getting the first, so the backup step is yours.

3.Getting your data out

The app exports a PDF summary intended for a doctor or dietitian appointment. Export it before any reinstall, and keep it somewhere you control.

Because the export is a normal file, what happens to it afterwards is up to you. Once it leaves the app it is no longer covered by the app's guarantees — if you email it, it is in your mailbox and your provider's.

4.Common questions

Why does a food I ate not appear in the results?
Some foods have no published composition data. Those are marked "no data" and are deliberately left out of the analysis rather than given an invented number. You can still log them; they simply do not generate hypotheses.

Why does the app say a marker is not a diagnosis?
Because it is not. A marker such as "lactose" or "gluten" describes what a typical portion of that food commonly contains. It is a fact about the food, not a prediction about you. Whether you react to it is exactly what the diary is for finding out.

Can the app tell me what I am intolerant to?
No, and it will not pretend to. It finds statistical associations in your own records and reports them with confidence intervals, so you can see how strong the evidence actually is. Identifying an intolerance is a clinical matter — often breath testing, or a supervised elimination and reintroduction. The app is for arriving at that appointment with real data instead of a vague story.

Why does it refuse to support IgG4 food panels?
Because the major allergy societies advise against them for diagnosing food intolerance. The app explains this in context, with citations, rather than silently omitting it.

Is there a subscription?
No. One purchase, no advertising, no in-app purchases, no analytics.

Which languages are supported?
English, German, Spanish, Chinese and Hindi, including the ingredient database.
