Version 2026-11-01 · Last updated: 1 November 2026 · Effective on publication
In short: Sheina stores your baby's data in your account in the cloud (Google Firebase, region me-west1, Israel), so both parents see the same record and nothing is lost if you change phones. The app's own engine calculates the recommendations from what you record, and we keep a record of each recommendation so we can check and improve it. To improve the app we also record how it is used — which screens and actions, from a fixed list, linked to your account. This is part of using the app; to stop it and have what was recorded deleted, write to us at hello@sheina.ai. We do not sell your data, there are no ads, and we do not use your data for advertising tracking.
Version 2026-10-31. It takes effect on the day it is published on this page.
Sheina AI is operated by PALATNIKS LTD ("we"), which is the controller of the database for the information described here.

You are not required by law to give us any information. An account is needed to use the app (section 2). Everything else in the journal is recorded only if you choose to record it. If you do not provide something, the feature that depends on it will not work. Usage analytics (section 7) are not required by law; they are part of how the app works, and you can ask us to stop them.
An account is required to use the app. There is no anonymous mode. You sign in one of three ways:
We store your email address, first name, parent gender (Hebrew needs it to address you correctly), interface language, a user id (Firebase UID), the identifiers of the sign-in service you used, when the account was created, which versions of the Terms of Use and this policy you accepted and when, and the choices you made in the app's privacy settings.
We do not collect a phone number, a postal address or a parent's date of birth.
Information you enter that describes your child:
Called out separately because it is information of special sensitivity:
This is stored only if you choose to record it. We use it to show it to you and to the other parent in your family, in reports and charts, and in the app's features that depend on it. It is not part of usage analytics (section 7) and is not exposed by a public share link (section 11).
Sheina is not a medical device and does not diagnose. See the medical section of the Terms of Use.
Sheina's recommendations (for example, when to start settling for the next sleep) and insights are calculated by the app's own engine from what you record — your baby's age and the sleeps, feeds and events in the journal — and become more personal as data accumulates. The app currently has no AI chat, and your data is not sent to any external AI service. Earlier versions included a chat, in which a message you typed was sent through our server to an AI provider (OpenAI or Google Gemini) to produce a reply. That chat is no longer available.
Recommendation records. For each recommendation, the app stores a record in your baby's shared record. It is part of the journal, both parents can see it, and it contains no names and no free text:
Per-parent entries follow usage analytics. The parts that are about a particular parent — when the recommendation was shown to that parent, whether that parent opened the explanation, and the settling attempts that parent started — are recorded together with usage analytics (section 7): if a parent asked us to stop usage analytics, these entries are not recorded for that parent. The recommendation itself, its inputs, the learning state and the outcome are part of the baby's shared journal record, which both parents see.
We use these records to run the recommendations (the engine learns from earlier outcomes), to investigate a recommendation you report as wrong, and to measure and improve the engine's accuracy (section 8). Some of the details listed above are switched on from our servers, so not every record contains all of them.
To understand how the app is used and to improve it, the app records usage analytics. They are recorded automatically for a parent who has been told about them: a new parent accepts this policy when signing up. A parent who already had an account is recorded only if they acknowledged, in the app, the one-time notice that the policy had been updated, which listed what is recorded and how to stop it (earlier versions of the app showed it); a parent who did not acknowledge it is not recorded. There is no switch for usage analytics in the app.
To stop usage analytics, write to us at hello@sheina.ai from the email address of your account. Providing this information is not required by law, and stopping it has no consequence: every feature of the app works the same.
What is recorded: which screen of the app was opened and which action was taken, from a fixed list (for example "opened the reports screen" or "started a sleep"); the time; a coarse result (succeeded, cancelled, failed); a coarse kind (for example feeding, diaper or sleep, or the sign-in method); a duration range; whether the action was yours or automatic; the app version and the platform (iOS or Android). Events are collected on the device and sent in batches to a separate database (Google Cloud Firestore, region me-west1, Israel), where they are stored under your user id. They are linked to your account.
What is never recorded: anything you type, your baby's name or identifier, amounts (millilitres, minutes, sides), any health screen or action (temperature, medication, vaccines, growth, milestones), promotional codes, product ids or prices, email addresses, links or sign-in codes, anything about the other parent, and device or advertising identifiers.
When we stop it at your request, recording stops and the usage events already collected are deleted, both those still waiting on your device and those in our database. From then on, the per-parent entries in the recommendation records (section 6) are not recorded for you either. Deleting your account deletes your usage events too.
Legal basis. We record usage analytics on the basis of your informed consent, which you give by accepting this policy when signing up, or by having acknowledged the update notice in the app. You can withdraw that consent at any time by asking us to stop usage analytics (write to us at hello@sheina.ai).
We use usage analytics only to understand how the app is used and to improve it — for example to find screens that confuse parents or flows that fail. They are not used for advertising or sold, and no one outside our service providers (section 16) receives them: they are not given to an analytics company, but stored in our own database at Google Firebase. Collection is also controlled from our servers, so at times nothing may be recorded even while the setting is on.
Aggregate statistics in the future. We may in the future produce statistics about babies' sleep in aggregate form — for example average sleep durations by age group. We will do so only after the result has been tested to ensure that no family, parent or baby can be identified from it, and we will update this policy before doing so. We do not produce or publish such statistics today.
The journal, the baby's details and the recommendation records are stored in Google Cloud Firestore and processed by Cloud Functions in region me-west1 — Israel. Usage analytics are stored in a separate Firestore database in the same region.
Some Google services we use run on Google's global infrastructure and may process data outside Israel: Firebase Authentication (your sign-in account), Firebase Crashlytics (crash reports) and Firebase Cloud Messaging (notifications). See section 21.
Your data is not kept on the device alone. Deleting the app removes the local copy only; the cloud copy remains until you delete your account. See section 18.
You can invite a second parent into your family. A parent who joins:
The recommendation records note which parent saw a recommendation and when, so a parent can see, through the shared record, that the other parent viewed it. This is not recorded for a parent who asked us to stop usage analytics (section 7).
If one parent leaves — leaves the family or deletes their account — the baby and the shared journal stay with the parent who remains, including the entries the departing parent made. When the departing parent deletes their account, their name is removed from those entries, which then read as "a parent"; their internal user id stays in the shared record as the technical marker of who created or changed an entry, without a name; and the records of which recommendations they saw are converted into counts with no identifier. Section 18 has the full details.
An invite link is a credential. Whoever holds it can join the family and see the whole record. Send it only to someone you mean to give full access.
You can send the invitation yourself (over WhatsApp, say) or ask us to email it. If you choose the second option:
On Android, the app reads the Google Play install referrer once, after installation. If the install came from an invitation link, the app takes the invitation code from it; if it came from a partner's link, the partner code (section 13A). If it holds neither, the app does nothing with it.
You can create a link that shares the journal — with a grandparent, a nanny or a sleep consultant, for example.
You decide who receives the link, and you are responsible for that choice.
Resend is used to deliver service-related email messages. Messages sent through it include:
The app also includes an optional "email tips and updates" preference, stored on your account, which you can turn off at any time. If we send optional tips or product updates in the future, they will be sent according to that preference, and you will be able to stop them through the app setting or an unsubscribe link.
Turning off optional tips and updates does not stop necessary service messages, such as sign-in links or family invitations you ask us to send.
For delivery, the provider receives the recipient's email address and the message content, and may retain technical delivery logs under its own policies. Verification and email-address-change messages sent by Firebase Authentication are handled by Google.
We do not sell email addresses and do not use them for advertising tracking.
Some offer codes, and the links at sheina.ai/r/…, belong to partners — for example influencers, sleep consultants or professionals — who may receive a reward from us for families that came through them.
Professionals can leave their details at sheina.ai/pro to get to know and try Sheina AI, receive explanatory materials, explore a professional collaboration (including joining the partner network) or hear about taking part in our podcast. This section is about the details of people who contact us there or are partners, not about parents. The controller is PALATNIKS LTD (section 1).
If you allow notifications, we store a device token for each install. Delivery is through Apple APNs and Google FCM, including iOS Live Activities on the lock screen.
Note that notification text contains your baby's name and the other parent's first name — "Dana put Noam down", for example. That content passes through Apple's and Google's notification infrastructure.
Notifications scheduled locally on the device (engine alerts, some reminders) never reach a server.
The app contains no advertising, and we do not sell personal information.
We use these providers to run the service. They process information on our behalf for the purposes described here:
| Provider | What for |
|---|---|
| Google (Firebase and Google Cloud) | Database (Firestore), server functions, file storage for the reports you send (Cloud Storage), sign-in accounts (Firebase Authentication), crash reports (Crashlytics), notifications (FCM), app-integrity checks (App Check), hosting of the share-link and invitation pages, server logs |
| Apple | Sign in with Apple, notifications (APNs) and Live Activities, App Store payments, App Attest integrity checks |
| Google Sign-In, Google Play payments, the Play install referrer (invitations and partner links), Play Integrity checks | |
| RevenueCat | Subscription management (section 13) |
| Resend | Delivering service email (section 12) |
| Cloudflare (Turnstile) | Checking that the form on the professionals page was sent by a person, when the check is on (section 13B) |
| Netlify | Hosting the sheina.ai website, the download page and partners' link pages (sections 13A and 25) |
We do not use advertising networks, data brokers or third-party analytics services. We may disclose information if the law requires it or to protect rights and safety.
Your account, your baby's record, the journal, the recommendation records and usage analytics are kept for as long as the account exists. We do not delete them automatically because time has passed or because your child has grown. You can delete individual entries in the app at any time, and the whole account as described in section 18.
Shorter periods: crash reports — 90 days; bug reports and sleep-calculation reports — up to 90 days; server logs — about 30 days; a family invitation is valid for 7 days, and the invitee's email address is kept only while the invitation is pending.
You can delete your account in the app (Settings → Delete account) or by email (see the end of this section). The deletion is performed on our server.
In every case, deleting your account:
If another parent is in the family: the baby and the shared journal stay with them — including the entries you made and the recommendation records — and you are removed from the family. Your name is removed from the entries, which then read as "a parent"; your internal user id remains in the shared record only as the technical marker of who created or changed an entry, without a name; and the records of which recommendations you saw are converted into counts with no identifier. If you hold the family subscription, the app asks you to transfer it to the other parent first.
If you are the last parent: the baby's record is deleted together with everything in it — the journal, sleep history, health information, photo, recommendation records and correction history.
What may be kept, and why:
Sign-in providers. Deleting your Sheina account does not delete your Apple or Google account. If you signed in with Apple, you can remove Sheina from the apps using your Apple ID in your iPhone's settings (Settings → your name → Sign-In & Security → Sign in with Apple). If you signed in with Google, the app tries to revoke its access to your Google account during deletion; you can also check this at myaccount.google.com, under third-party connections.
Deleting your account does not cancel an active subscription. Cancel it in your App Store or Google Play subscription settings, or billing continues.
Pausing instead of deleting. You can also deactivate the account temporarily in Settings. While deactivated, the account cannot be used; the data is kept and returns when you reactivate.
You can also write to hello@sheina.ai from the account's email address. We will act within 30 days. The same details appear on the Delete account page.
Under the Israeli Privacy Protection Law, 1981, you may:
To make a request, write to hello@sheina.ai from the account's email address. We will answer within 30 days. If you believe we have not handled your request or your information properly, you may complain to the Privacy Protection Authority at the Israeli Ministry of Justice. If you live outside Israel, you may also have rights under the law where you live, including the right to complain to your local data-protection authority.
If you are one of two parents, deleting your account does not delete the other parent's account or the record that stays with them.
These are measures, not a promise of outcome: no online system can be guaranteed absolutely secure.
The main database is in Israel. Some of our providers process information outside Israel as well, including in the United States and in the European Union: Google (Firebase Authentication, Crashlytics, Cloud Messaging), Apple, RevenueCat, Resend and Netlify. They do so as our service providers, for the purposes in section 16.
Sheina is for parents and carers, to record information about their own children. Information about the baby is entered by the parents. The app is not designed for children to operate, is not marketed to children, and we do not knowingly collect information directly from children.
By entering information about a child you confirm that you are their parent or legal guardian, or that you have that person's permission.
Between September and October 2026, some versions of the app asked parents for consent to keep a pseudonymised copy of the journal events they recorded, for research. We have stopped this collection, and current versions of the app no longer ask for this consent. What was collected (journal events without names, some of which included notes you had written) is kept apart from the journal, is not used for analysis, and is held while we decide whether to delete it. Pseudonymised means the information is not anonymous: it can still be linked to a family by someone who holds the key.
If you gave this consent, you can withdraw it at any time in Settings → Privacy & research. Withdrawing deletes the research events you recorded. Deleting your account deletes them too, and so does deleting the baby's record.
We update this policy from time to time. A material change will be brought to your attention in the app or by email, and where a change requires your consent, we will ask for it. The version and date appear at the top of this page.
sheina.ai is hosted by Netlify. It has no ads, no cookies and no third-party analytics.
On the download page (sheina.ai/download), which our QR codes point to, we count visits to learn which source they came from: the time, the source named in the link (for example src=tipat_halav), the device type only (iPhone, Android or computer), and whether you were sent to a store automatically or by tapping. We do not store your IP address, your full browser identification, a device identifier or anything that identifies you, and visits cannot be linked to one another. In the same way, on sheina.ai/pro we count visits, taps on the download button and forms that were received, with only the source named in the link (for example utm_source=faceforward2026) — never anything typed into the form. Netlify, as the host, processes technical request data under its own policies.
Once you go to the App Store or Google Play, that store's privacy policy applies. The Google Play link includes the source name so that Google Play can report to us how many installs came from each source, in aggregate only.
Partners' link pages (sheina.ai/r/…) are described in section 13A.
