Terms of use

Effective 3 November 2026

Diet Handbook is an iPhone app for keeping recipes and planning meals around what you and the people you cook for can’t eat. It is made and run by Ivan Shakhorski as an individual developer. Signing in means you agree to these terms and to the privacy policy. If you don’t agree, don’t use the app.

Not medical advice

Diet Handbook is not medical advice and does not replace a doctor or a dietitian. When it says a recipe is free of something, that comes from reading the recipe’s ingredient lines and matching each one to a food. The lines can be wrong, a product can contain more than its name says, and a recipe can be cooked differently from how it was written. Always read the packet, and ask a professional about a diagnosis, a serious allergy or a diet a doctor gave you. When the app can’t read a line, it says it doesn’t know rather than guessing, and such a recipe is never shown as safe.

Calorie and nutrition figures are estimates from public food tables, worked out from the same lines.

Your account

You sign in with Apple or Google. You are responsible for what is done from your account. You must be at least 13. You can export everything it holds and delete it at any time from Account and settings; deletion happens at once, and the privacy policy says what goes and the little that stays.

Recipes you offer to the community

When you choose Community for a recipe, you’re telling us that you wrote it and that its photos are yours, or that you have the right to share them. The recipe stays yours. You give us a non-exclusive, worldwide, royalty-free licence to show, store and adapt it (for example, to scale servings, list ingredients or check allergens) in the app and on our website. Before anyone else sees it, a model and sometimes a person check it. Taking it back to My handbook removes it from the community catalogue. If you delete your account, an approved recipe that other people have already planned or saved may stay in the catalogue, without your name and without your photos. We keep a record of which version of these terms you agreed to for as long as we keep the recipe.

What isn’t allowed

There is no tolerance for objectionable content or abusive users. A recipe or photo is refused or removed when it is:

• Copied from somebody else without the right to share it.
• Unsafe or misleading, including allergen or diet claims that aren’t true, or a method that could hurt somebody.
• Not a recipe, or a photo that isn’t of food.
• Spam, advertising or links to sell something.
• Offensive: hateful, harassing, sexual, violent, or aimed at a person.
• Illegal, or about somebody who hasn’t agreed to it.

We can remove any recipe or photo from the community, and suspend or close an account that breaks these rules or harms other people. You can block an author from any of their community recipes, and their recipes disappear for you; they are never told.

How we decide what appears in the community

Before a person sees anything you offer to the community, an automated model checks its method and each of its photos. The model can hold a recipe for a person to review, or keep a photo to you and your household, but it never removes a recipe: a person makes every refusal and takedown. If enough people report a community recipe, it is taken out of the community until a person has looked at it.

Whenever we hold back, refuse or remove one of your recipes or photos, we tell you on the recipe: which rule it breaks, the reviewer’s own note where there is one, and whether a person, our automated check or reports decided. We never tell you who reported a recipe or what they wrote. If you think we got it wrong, tap Ask for another look under the decision: a person, never the model, reads your message and answers you there, usually within a day. You can also fix your recipe and offer it again at any time.

Notices about a recipe

Anyone can tell us about a recipe in Diet Handbook, with or without the app: that it copies their work, breaks the law, is about them, or has wrong allergen information. In the app, use Report a problem under the recipe; otherwise follow Report a recipe, which says what to send and emails it to us. A person reads every notice and answers it, usually within a day, and may take the recipe out of the catalogue while deciding. The sender hears what we decided and why. If we hold back or remove a recipe, its author is told the reason, whether a person or an automated check decided, and how to ask again. We never give the author the sender’s email address.

AI features

The app can read a recipe from text, a photo or a link, write one for a wish, and suggest meals for a week. A model does the reading and writing, and it can be wrong: check what it gives you before you save it. A model never decides what is safe for anyone. Which recipes are safe for whom is worked out on our server first, and a model only ever chooses among those. A recipe a model wrote is marked “Written with AI” and can’t be offered to the community.

Plus

Plus is an optional subscription that unlocks Suggest meals. Everything that keeps you safe stays free, and so does reading and writing recipes.

• It is bought and billed through Apple, to your Apple Account, at the price shown before you confirm.
• It renews automatically at the end of each period unless you cancel at least 24 hours before it ends. Your Apple Account is charged within 24 hours before the new period starts.
• Cancel or change it in your iPhone’s Settings → your name → Subscriptions. Cancelling stops the next renewal; Plus stays until the end of the period you paid for.
• Deleting your Diet Handbook account does not cancel the subscription. Cancel it with Apple first.
• Refunds are handled by Apple, at reportaproblem.apple.com.

The service

We try to keep Diet Handbook working and your data safe, but it is offered as it is, without a promise that it will always be available or free of mistakes. As far as the law allows, we are not liable for loss that comes from relying on it in place of reading the packet. Nothing here limits rights you have under consumer law where you live.

We may change the app and these terms. When a change matters, the date at the top changes, and a change to the community rules is shown in the app before you offer another recipe. You can stop using the app and delete your account at any time.
