Support

Updated 29 October 2026

Diet Handbook is made by one person, Ivan Shakhorski. Write to support@diet-handbook.com and you will get an answer from Ivan, usually within a few days.

To say what you think without needing a reply, use Send feedback in the app: tap the person button at the top of Recipes, then Send feedback. Those messages are read but can’t be answered, because the app has no way to write back.

What to include

• What you did, what you expected, and what happened instead.
• The app version, shown at the foot of Account and settings, and which iPhone and iOS version you have.
• A screenshot, if something looks wrong.
• Not your allergies or anybody’s health details unless they are the problem. If they are, say only what is needed.

Common questions

A recipe says it is free of something it contains

Open the recipe and tap Report a problem under it, then choose “Allergen or diet information is wrong”. That report goes to the person who checks the ingredient data, and it is the fastest way to get it fixed. If it is urgent, email as well.

A recipe copies my work, or is about me

You don’t need the app to tell us. Report a recipe says what to send; a person answers, usually within a day, and you hear what we decided.

How do I get a copy of my data?

In Account and settings, under Your data, tap Export your data. The app prepares one file and opens the share sheet to save or send it.

How do I delete my account?

In Account and settings, scroll to the end and tap Delete account. It is deleted straight away, with what you wrote, your plans and your diet profiles. The privacy policy says exactly what goes and the little that stays.

How do I leave a household?

Open People from the person button at the top of Recipes. Leave this household is at the end of the page. You keep a copy of the meals you were eating from today on.
