Correct it once.
Eira starts there next time.

Soon — and we would rather say that than name a date we might miss. Eira is in the last stretch before submission to the App Store, and review takes as long as it takes. Leave your email and you'll hear from us the morning it's live — and now and then before that, a short note about something we built or took out, and why. Nothing else.

We store your name, your address, the exact sentence you agreed to with the date and time you agreed to it, and a note that the signup came from this site. It is never sold, never shared, and never handed to an advertiser. You'll get one email asking you to confirm the address, one when Eira goes live, and now and then a short note about something we built or took out, and why — which is what “news from Eira” beside the checkbox means. Nothing else. Unsubscribing stops all of it immediately; we then delete your name and address, and keep only the record that this address asked not to be written to again — see the privacy policy.

Honestly: it's an estimate, and it says so. Eira shows a range rather than a false decimal, and the number itself always comes from a nutrition database rather than from the model. Correct a portion and Eira starts from your figure the next time you log that same food — that food, not everything else you eat. If precision matters for a particular item, scan the barcode: that identifies the product instead of estimating it by eye, which is as close as Eira gets. The figures still come from a database rather than from the packet in your hand, so they can be missing or out of date — Eira shows you what it logged, with an undo beside it.

Photo and voice logging work from what the food is, not from a fixed menu — so a home-cooked dish, a regional staple or something with no English name is described the way you'd describe it, and you correct anything it gets wrong with a tap. Packaged food is a barcode scan — the code identifies the product, and the figures come from a nutrition database rather than from the packet in your hand. And when a product isn't in any database — a local brand, something from a market stall — you photograph the nutrition panel and type in what it says, once. From then on it is known, for you and for the next person who scans it.

No — there is no import, and nothing you logged elsewhere comes across. Eira starts on the day you start, and what it knows it learned from you: the portions you corrected, the things you told it, each one dated to the day it became true. So the first week is a first week. The second one starts from what you taught it in the first, and the quickest way to get there is to log the handful of things you eat most — after that they sit in Recents, one tap away.

Before anything is stored, the picture is stripped of its metadata — including where it was taken — and downscaled. The upload you sent is deleted as soon as it has been read, and anything left of it is swept within 24 hours. What is kept belongs to the meal: delete the meal and the picture goes with it, and deleting your account takes every one of them. Photos are never sent to the tracing service that records how Eira reasons, and never to analytics or advertising. The privacy policy gives the timings.

No. The phone app is the whole product. If you do wear one, the watch adds voice quick-log, one-tap water, complications and a glance — the wrist becomes an input, not just a second screen.

Nothing is taken away. You move to a free Lite account: the compounding features pause, and every meal, every fact and every note stays readable, editable and exportable. If you come back, the memory resumes from where it stopped.

Eira is built with that history in mind — there is no red “over budget” state, no shaming, nothing that punishes a gap, gentle mode puts the figures away entirely, and coaching that would push restriction is filtered before it reaches you. The fasting timer will not start until you have read and acknowledged who it is not for. But no food-tracking app is safe for someone with an active eating disorder, and Eira is not a treatment. If you are in treatment or in recovery, please use it only on your clinician's advice — and if food feels hard right now, the “Get help” screen lists support services and is never gated.

Yes — Eira is for adults, and you need to be 18 or older to use it. The app asks for your date of birth once and checks it on the server, so it is a rule rather than a tick-box. That is a deliberate line for a food-tracking app with a coach in it, not a formality.

Only what a request needs, only with your explicit consent, and only to providers acting as our processors — on our instructions and for no purpose of their own. Those instructions forbid training on what we send, and your name, email and account identifier are never sent at all. We don't yet claim their signed terms prohibit training or cap retention: until each provider's data agreement is in place we would rather say so than let an instruction read as a promise, and no health data reaches a provider before that. Nothing read from Apple Health goes to analytics or advertising. The full picture is in the privacy policy, written to be read.
