Privacy Policy
Effective October 31, 2026
BabyBoom ("the app") is a baby journal made by Marian Pavel ("we"). This policy explains what information the app collects, why, who can see it, and the choices you have. The short version: your baby's journal is kept on your phone and on our server so it can sync, only the family members you invite can see it, we never sell it or use it for ads, and you can delete it anytime.
Your baby's journal
When you use BabyBoom you enter information about your child: the baby's name, birth date, sex and a color for the app, and the entries you log, such as feeds, bottles, pumping, sleep, diapers, food and drinks, and their times, amounts, details and notes. Some entries can be about your child's health and growth: temperature, medicine, vaccinations, symptoms, doctor visits, weight, height and head size. You decide what to log, and every field except the baby's name is optional.
The journal is saved on your phone first, so the app works offline. It's also stored on BabyBoom's server, so it can be backed up and synced between your phones and the people you share it with. We use this information only to provide the journal to you and your family. We don't sell it, we don't use it for advertising, and we don't share it with analytics or advertising partners.
If your phone shows BabyBoom widgets, the latest entries and running timers are also kept in the app's private storage on your phone so the widgets can show them. When you export your journal as a CSV file, the file is created on your phone and goes only where you choose to send it.
Your account
You don't need to sign up. When you first open the app, it creates an anonymous account on our server: a random identifier with no name or email. We also keep:
- Your name, if you add one (for example "Mom" or "Grandma"), which family members see next to your entries.
- Sign in with Apple or Google, if you use it: the provider's stable identifier for your account and your email address as the provider shares it (with Apple you can choose a private relay address). We use them only to sign you in and to keep your journal when you change phones. We never see your password.
- Sessions: a sign-in token for each phone (stored only as a one-way hash), the platform and device model, and when it was last used, so you can stay signed in.
- Premium status: whether you have Premium, which plan, and until when.
Sharing with your family
A family is the group that shares a journal. Everyone in a family can see and edit all of its babies and entries, and sees the family's name, the names and roles of the other members, and who logged each entry. People join only through an invite link or code that a member creates; each invite works once and expires after 7 days. We keep who created an invite and who accepted it. Free families can have up to 2 members, Premium families any number. An owner can remove members, and any member can leave.
Information collected by services we use
Purchases: Apple, Google and RevenueCat
Premium is bought through the App Store or Google Play, which handle the payment; we never see your card details. We use RevenueCat to check purchases and manage subscriptions. It receives your random BabyBoom account identifier, your purchase history and receipts from the store, and basic device and app information. See the RevenueCat privacy policy.
Usage statistics and crash reports: Firebase Analytics and Crashlytics (Google)
Help us understand how the app is used and fix problems. Analytics records app usage events: screens opened and actions such as an account created, a baby added, an entry added, a timer started, an invite created or accepted, the Premium screen shown or a purchase made. For an entry it records only which kind it was (for example "bottle" or "sleep"), never its details, times or notes, and never your baby's name. It also collects device information (model, operating system and version, language), an app instance identifier, your random BabyBoom account identifier (so the same person on two phones counts once), and an approximate location (country or region) derived from your IP address. Crash reports include technical details such as the stack trace, device model, operating system version, free memory and disk space, and a random installation identifier. You can turn both off anytime in the Family tab, under Share usage statistics. In regions where consent is required (such as the EEA, the UK and Switzerland), analytics storage stays off unless you allow it in the consent form.
Advertising: Google AdMob
The free version shows ads through Google AdMob; Premium families see none. To show, measure and limit ads and to prevent fraud, Google and its ad partners may collect your device's advertising identifier (IDFA on iOS, Android Advertising ID), IP address, device and app information, and how you interact with ads. They don't receive your journal. See how Google uses information from apps that use its services.
- EEA, UK and Switzerland: on first launch a consent form (Google's User Messaging Platform) lets you choose whether your data may be used for personalized ads and measurement. You can change this anytime in the Family tab, under Ad privacy choices.
- iOS: the app asks for permission to track through Apple's App Tracking Transparency prompt. If you decline, the advertising identifier is not shared. You can change this in iOS Settings → Privacy & Security → Tracking.
- Android: you can reset or delete your advertising ID in Android Settings → Privacy → Ads.
Non-personalized ads may still be shown when you opt out.
How the services handle data
Each service processes data under its own privacy policy:
- Google / Firebase: policies.google.com/privacy and firebase.google.com/support/privacy
- RevenueCat: revenuecat.com/privacy
- Apple (Sign in with Apple, App Store): apple.com/legal/privacy
- Google AdMob ad partners: listed in the consent form under List of partners
BabyBoom's server runs on a cloud server we rent and administer ourselves. Connections to it are encrypted and pass through Cloudflare, which protects the server from attacks; no other company receives the journal for its own use. We don't sell personal information, and we don't collect your contacts, photos or precise location.
How long we keep it, and deleting it
We keep your account and journal for as long as you use the app. Delete account, in the Family tab, removes from our server, for good: your account, your sign-in identities and sessions, and every family in which you are the only member, with its babies and entries. In families you share with others, the journal stays with the other members (it's theirs too), your name is removed from it, and if you were the owner, the longest-standing member becomes the owner. Signing out of a guest (anonymous) account doesn't delete it: the journal can't be reached again but stays on our server, so delete your account first if you want it gone. To delete only a baby or an entry, delete it in the app.
When we update the server, we take a backup of the database first and keep the last 14. Deleted data disappears from backups as they're replaced. Data that the services above collect is kept according to their own policies.
Legal bases (EEA and UK)
We process the journal and your account to provide the service you asked for (performance of a contract). Health information you choose to log about your child is processed on the basis of your explicit consent, which you give by entering it and can withdraw by deleting it. Analytics, crash reports and personalized ads rely on your consent where the law requires it, and otherwise on our legitimate interest in keeping the app stable and free.
Children
BabyBoom is meant for parents and caregivers, not for children to use. The information it holds about a child is entered by their parent or caregiver, who controls it and can delete it at any time. If you believe someone has entered information about your child without your permission, contact us and we'll help remove it.
Your rights
Depending on where you live (for example under the GDPR or US state privacy laws), you may have the right to access, correct, export or delete your personal data, and to object to or restrict its processing. You can see and edit your journal in the app, export it as CSV with Premium, and delete it from the Family tab. For anything else, including a copy of your data, email us and we'll help, including forwarding a request to the relevant service. You can also complain to your local data protection authority.
Changes
If this policy changes, we'll update this page and its effective date.
