Privacy

Last updated: 8 September 2026

This explains what happens to your information when you use theluckyegg.com or the juni app. It is written to be read, not to protect us, so it says plainly what we collect and where it goes.

The Lucky Egg is published by Green Label LLC. Dr. Lucky Sekhon is a practising reproductive endocrinologist, and her clinical practice is a separate organisation from this website. Where that distinction matters below, we say so.

The short version

• We do not sell your information, and we never will.
• Nothing you type into the app leaves your phone, apart from crash reports and anonymous usage counts.
• Six of the seven calculators on this site run entirely in your browser and send nothing anywhere. One of them sends two numbers to our server to work out its estimate.
• If you give us your email address, it is so we can send you what you asked for. You can leave at any time, from the link at the bottom of every email.
• Reading this site is not a medical consultation, and nothing here becomes part of a medical record.

When you give us your email address

You can join three lists: the monthly newsletter, the free fertility preservation guide, and early access to the juni app. All three are held in Mailchimp, which stores them on our behalf in the United States.

We record your email address, which of the three you asked for, and the date. For early access we also record whether you signed up on an iPhone or an Android phone and which page you came from, so that we send you the right download link and know which pages are actually helping people find us. We do not ask for your name, your age, your diagnosis or anything about your treatment.

Every email we send has an unsubscribe link, and using it removes you. If you would rather we deleted you outright, write to us and we will.

Mailchimp records whether an email was opened and whether a link in it was clicked. We use that only to tell whether the writing is landing.

When you ask for a consultation

The consultation request form asks for your first and last name, your email address, your phone number, whether you are able to travel to New York, and the reason you are getting in touch.

That form does not submit to this website. It posts directly to a form belonging to Dr. Sekhon’s clinical practice, and this website neither stores nor sees what you wrote. It is a way of reaching her office, and once it arrives there it is handled under that practice’s own privacy practices, not this one.

The form is not a medical record and is not a place for anything urgent. If something is urgent, call your clinic.

The calculators

Six of the seven calculators — the IVF due date, beta hCG, egg freezing, frozen embryo transfer date, embryo grading and AMH-by-age tools — run entirely inside your browser. The dates, hormone levels and grades you enter are never transmitted, never stored, and disappear when you close the tab. We can never see them.

The seventh, the euploid embryo predictor, works differently, and it is only fair to say so plainly. To produce its estimate it sends your age and your AMH level to a model we run on our own servers. It sends nothing else — no name, no email, nothing that identifies you — and the result comes straight back to your screen.

Our server writes down the two numbers and the time they were sent. That record is not attached to your name, your email address or your device, and we cannot tell whose it is. We keep it for 30 days and then it is deleted.

That estimate comes from a statistical model built on population data. It is not a prediction about you, and it is not a diagnosis. Please go through any number this site gives you with your own fertility team.

Blocked signups

Automated bots try to sign up to mailing lists constantly, and in August 2026 several hundred did. To tell a bot from a person, the signup forms check how the form was filled in. When a submission is blocked as automated, we keep a short record of it — the date, the form, why it was blocked, the IP address and the email address that was submitted — and only the most recent two hundred of those are kept at all. Older ones are discarded automatically. If your genuine signup is ever blocked by mistake, that record is how we find it and fix it.

Analytics and how we know what to write next

We use Google Analytics, Piwik PRO and Ahrefs Web Analytics to understand which articles and tools people find useful. These record which pages were viewed, roughly which country or region the visit came from, and what kind of device was used. Google Analytics and Piwik PRO set cookies to recognise a returning browser; Ahrefs does not use cookies at all.

We have deliberately turned off Google’s advertising features, so this data is not used to build an advertising profile of you, and it is not connected to any Google account.

We also use OptiMonk, which shows the occasional message about the book. It records that a message was shown and whether it was clicked. Nothing about your reading, your searches or anything you typed into a calculator is attached to any of this.

We show a small number of our own promotional blocks on articles. They are our own, they are not an ad network, and no third-party advertiser receives anything about you.

The juni app

juni is our IVF companion app, in beta at the time of writing.

Everything you record in juni stays on your phone. Your cycle dates, your hormone and lining measurements, your embryo records, your beta results and anything you type are stored in the app’s own database on the device and are never sent to us or to anyone else. There is no account, no login, and no copy on a server. If you delete the app, that information goes with it.

Two things do leave the phone, and only these two:

Crash and problem reports. When something goes wrong, or when you use “Report a problem”, a report is sent to Sentry, an error-tracking service. It contains what the app was doing when it broke. If you write a description or attach a screenshot, those are sent too, because you chose to send them. Reports may include a short recording of the screens you moved through; on the version distributed to beta testers, the text and images in that recording are hidden before it leaves your phone.

Anonymous usage counts. The app reports what kind of thing happened — a stage was reached, a measurement screen was completed, an article was opened, a reminder was tapped — to Google Analytics. It never reports what you entered. No measurement, no date, no embryo grade or count, no text you typed, ever leaves the phone in these counts. They are tied to a random identifier belonging to that installation of the app, not to you, and we have turned off the Google advertising features that could connect it to a person.

Reminders are scheduled by the app on your own phone. Nothing is sent to a server to make them happen, which is why they still work when you have no signal.

Children

This site and the app are written for adults making decisions about their own fertility care, and are not intended for anyone under 18. We do not knowingly collect anything from children.

Where your information is held

We are based in the United States and the services described above store information in the United States.

What you can ask us to do

Write to us at hello@theluckyegg.com and we will:

• tell you what we hold about you, which for most readers is nothing more than an email address on a list;
• correct it;
• delete it.

If you asked Dr. Sekhon’s practice for a consultation, that request is held by the practice and not by us, so ask them directly.

Changes

If we change how any of this works, we will change this page and update the date at the top.
