Terms
Last updated 25 August 2026.
Beatrice is made by one person, Brian Long, referred to below as "the developer". These terms cover the Beatrice iPhone app, this website, and the shared links the app can send on your behalf. Together those are "the service". Using the service means you accept what is written here.
The short version.
What you write stays yours. Do not use Beatrice to harm anyone or to store other people's information you have no business storing. The app is in beta and will sometimes break. It tracks cycles but it is not birth control, and none of it is medical advice. If it stops being worth it, take your data and go.
You need to be at least 16 years old. Beatrice holds journal entries, health records and notes about named people, and that is not material to put behind an account a child controls. If you are under 16, please do not create an account.
You also confirm you are not located in a country subject to a United States embargo, and that you are not on any United States list of prohibited or restricted parties.
You sign in with an email address or with Apple Sign In. Keep your sign-in details to yourself. You are responsible for what happens under your account. If you think someone else has access to it, write to hello@beatriceapp.com.
One person, one account. Do not share an account with someone else. A household is the supported way for more than one person to see the same material, and it shares only what is scoped to that household.
You keep ownership of everything you put into Beatrice. Notes, journal entries, photographs, task lists, health records, the answers you give to questions: all of it is yours.
You grant the developer a narrow, revocable permission to store, process and display that content, for one purpose only, which is running the service for you. That permission covers sending the necessary parts of it to the processors named in the privacy policy so the app can function. It does not extend to advertising, to selling anything to anyone, or to training any machine learning model. Deleting your content ends the permission for it.
This is the unusual part of Beatrice and it deserves saying plainly. The app is built to hold notes about people who are not you and who have not signed up for anything. Birthdays, photographs, what somebody told you about their divorce.
You are responsible for that material. By putting it in, you confirm you have a legitimate reason to hold it, that you will not use Beatrice to build a record about someone in a way they would object to, and that you will remove anything about a person who asks you to. Where the law in your country gives people rights over information held about them, those obligations are yours, because it is your relationship and your record.
Beatrice is not a contraceptive and must never be used as one.
The cycle tools estimate a likely window from the dates you have entered. An estimate is not a safe day, it is not protection, and it cannot prevent a pregnancy. If you are trying to avoid one, use an actual method of contraception and talk to a clinician.
More generally, Beatrice is not a medical device and it is not regulated as one. Nothing in the app is medical advice, a diagnosis, or a treatment recommendation, and that includes the cycle tools, the infant tracking tools, and anything Beatrice writes about either. Predictions are worked out from the dates you entered. They get less wrong with more data and they are never certain, which is why the app shows a range and a confidence word rather than a date and a percentage.
Talk to a qualified professional about your health, your pregnancy and your child. Do not delay doing that because of something an app said.
Some of what you read in the app is generated by a large language model. It is composed from what you have told the app, and it can still be wrong, clumsy, or oddly worded. Treat it as a starting point and check anything that matters.
Anything the app drafts for you to send to another person is a draft. You choose whether to send it, and once you do, it is from you.
Do not:
There are usage limits on the parts of the app that call an AI model. They exist so one account cannot spend the budget for everyone. Deliberately working around them is a reason for an account to be closed.
Beatrice can send a link to somebody who does not use the app, so they can answer a question or read something you sent. Those links are unguessable and expire. Anyone holding the link can open it, so treat one like an unlocked door and send it only to the person it is for.
Beatrice is early. Features change, move, and are sometimes removed. There will be bugs, including bugs that lose data. Keep your own copy of anything you could not stand to lose.
The service is provided as it is, with no warranty of any kind, express or implied, including any implied warranty of merchantability, fitness for a particular purpose, or non-infringement. There is no promise that it will be available, that it will be uninterrupted, or that anything in it is accurate. Some places do not allow a warranty to be excluded, and where that is true this paragraph applies only as far as the law allows.
Beatrice is free during the beta. If a paid tier is introduced, the terms will be published here first and you will be told inside the app before anything is charged. Nothing you have already written gets locked away behind a payment after the fact, and you can always export and delete your data at no cost.
You can stop at any time. Delete your account in the app, or ask at hello@beatriceapp.com, and the data goes with it. Deleting the app from your phone on its own does not delete what is stored on the server.
The developer may suspend or close an account that is being used to harm someone, that is breaking these terms, or that has to be closed for legal reasons. Where it is possible and appropriate to give notice and a chance to export first, that will happen.
To the fullest extent the law allows, the developer is not liable for indirect, incidental, special or consequential damages, or for lost profits, lost data, or a missed occasion, arising out of your use of the service. Total liability for any claim is limited to the greater of the amount you paid for Beatrice in the twelve months before the claim, or fifty United States dollars.
Nothing here limits liability for fraud, for death or personal injury caused by negligence, or for anything else that cannot lawfully be limited. Some jurisdictions do not allow these exclusions, in which case they apply only as far as they lawfully can.
These clauses apply in addition to everything above, and Apple requires them.
These terms will change as the app does. The date at the top moves when they do. If a change materially reduces your rights, you will be told inside the app rather than left to notice it here. Carrying on using Beatrice after a change means you accept it, and if you do not, the answer is to export your data and close the account.
These terms are governed by the laws of the State of Kansas, United States, without regard to its conflict of law rules. Any dispute goes to the state or federal courts located in Kansas, and you agree to their jurisdiction. If you are a consumer somewhere that gives you the right to bring a claim locally, or that applies protections you cannot waive, this paragraph does not take those away.
If any part of these terms is found unenforceable, the rest still stands. Not enforcing something once does not waive it. These terms, with the privacy policy, are the whole agreement between you and the developer about the service.
Brian Long, developer of Beatrice. hello@beatriceapp.com. Mail is read and answered by a person.
