Terms of Service

These terms are between you and Nikolay Lyutov, an individual established in the European Union, who builds and runs Day So Far. They cover daysofar.com and the Day So Far apps for iOS and Android. Making an account means accepting them.

The software is also open source. Running your own copy is governed by its licence, not by this document — these terms are about the service run at daysofar.com.

Day So Far gives you estimates of what you ate and a calorie target worked out from a formula. That is general information, not advice about your body. It is not a medical device, it has not been assessed by anyone as one, and nothing it says is a diagnosis, a treatment or a prescription.

Talk to a doctor or a registered dietitian before making a real change to how you eat, and especially if you are pregnant or breastfeeding, are under 18, have diabetes, kidney or liver disease, a heart condition, or take medication whose dose depends on what you eat. If a professional’s advice and this app disagree, the professional is right.

If you have or have had an eating disorder, calorie tracking can make it worse. This app counts things, every day, and will keep counting whether or not that is good for you. Please talk to someone before using it. In the UK, Beat takes calls on 0808 801 0677; elsewhere, this list has a line for most countries.

“Two eggs and some cheese” does not contain a fact about grams. A language model reads what you wrote, decides what you probably meant, and looks the nutrition up; the app marks a guess as a guess for exactly this reason. Barcode data comes from public catalogues written by other people and can be wrong or out of date. Targets come from population formulas, and you are one person.

Treat a single number as approximate and a trend over weeks as meaningful. Correct anything that looks wrong — that is what the conversation is for, and a correction rewrites the entry rather than appending to it.

You must be at least 16 to have an account. One account per person; it is yours and not to be shared. Keep the password to yourself, and tell support@daysofar.com if you think somebody else has it. The app emails you when a new device signs in, which is the fastest way to find out.

The profile details asked for at setup — age, height, weight, activity — decide your target. Nonsense in, nonsense out; nobody is checking them but the arithmetic uses them.

• Do not use it to break the law, or to build something that hurts people.
• Do not attack it: no probing for holes, no attempts to reach another account’s data, no getting round the rate limits, no scripting the chat endpoint. Genuine, good-faith security research is welcome — write first.
• Do not resell it, wrap it, or use it as an unpaid API for something else. Every conversation costs real money to answer.
• Do not scrape it, or feed it into a crawler.
• Do not upload anything you have no right to upload, or anything illegal.

There are ceilings on the routes that cost money or guard a password — around forty chat turns an hour per account, and tighter limits on signing in and on password resets. They are set well above what a person tracking their meals will ever reach. Hitting them repeatedly on purpose is a breach of this clause.

Your meals, photos, weights and conversations are yours. No ownership of them is claimed, and they are not used to train any model or shown to anyone else.

The only permission granted here is the narrow one needed to run the service for you: storing your data, sending it to the providers named in the Privacy Policy so a turn can be answered, and displaying it back to you. That permission ends when you delete the data.

The app itself — the name, the mark, the design, the code — stays with its authors, under whatever licence the source is published beneath.

Day So Far is provided as it is, free of charge, with no uptime guarantee and no warranty of any kind beyond what the law insists on. It is run by one person on one server. It will occasionally be down, features will change, and some of them will go away.

If the service is ever going to shut down, account holders will be emailed with enough notice to get their data out.

To the fullest extent the law allows, there is no liability for indirect or consequential loss, for lost data, or for any decision you made about your health on the strength of a number in this app. Where liability cannot lawfully be excluded, it is limited to what you have paid for the service — which, today, is nothing.

Nothing here excludes liability for death or personal injury caused by negligence, for fraud, or for anything else that cannot be excluded under the law where you live.

There is no charge for Day So Far today, and no payment details are collected. If a paid tier is ever introduced, existing accounts will be told beforehand, and no account will start being charged without agreeing to it first.

You can leave whenever you like: Delete account, in Settings, erases everything at once and needs no explanation.

An account can be suspended or closed from this side for a serious or repeated breach of §5, or where the law requires it. Except where that is impossible — a legal order, an attack in progress — you will be told why, and given a chance to get your data out first.

The service is operated from the European Union and EU law applies to it. If you are a consumer, nothing in these terms takes away the rights you have under the law of the country you live in — that protection travels with you, whatever this document says. Consumers in the EU can also use the European Commission’s consumer redress platform.

The service is available worldwide, including in the United States. Signing up from outside the EU is welcome; your data is stored in the EU either way.

If any clause here turns out to be unenforceable, the rest of the document still stands.

These terms can change. The date at the top says when they last did, and any change that materially affects you will be emailed to account holders before it takes effect. Carrying on using the app after that is acceptance; if you would rather not, delete the account.
