Is there a private baby tracker you can still share?
Short answer
Yes. Bunavi stores your baby's records in the EU (Frankfurt, Germany), encrypted in transit and at rest. It shows no ads, uses no advertising identifiers, never sells your data, and has no chatbot and no cloud AI. Sharing stays off until you invite someone. Your log is kept on a server, because sharing it live between phones needs one.
Android: in closed testing on Google Play; no public date yet.
What does Bunavi do with your baby's records?
A summary of Bunavi's privacy policy and of what the app does; the policy is what applies.
| Fact | What Bunavi does |
|---|---|
| Where your baby's records are stored | In the EU: profiles, logs, health entries and photos are stored with Supabase in Frankfurt, Germany (AWS eu-central-1). |
| How they are protected | Encrypted in transit (TLS) and at rest. Access is enforced row by row in the database, so an account can only reach the babies it owns or was invited to. |
| Who can see them | In the app, only the people who share that baby. The services named in the privacy policy process data for Bunavi; nothing is sold, rented or shared with advertisers. |
| Sharing | Off until you invite someone. Free for you and up to 3 others per baby (since version 1.7.0); each invite code is single-use and expires after 7 days, and the baby's owner can remove anyone in Settings. |
| Ads and ad identifiers | No ads and no advertising identifiers. Bunavi builds no advertising or analytics profile of you. |
| App Store privacy label | It has no “Data Used to Track You” section. Data Linked to You: Health & Fitness, Purchases, Contact Info, User Content, Identifiers (User ID, Device ID), Other Data. Data Not Linked to You: Usage Data, Diagnostics. Labels are the developer's own statement, which Apple does not verify. Checked on the US App Store page, 30 October 2026. |
| AI | No chatbot and no cloud AI. Nothing from your baby's log is sent to an AI service or used to train AI. On iPhones that support Apple Intelligence (iOS 26 or later), a few optional writing touches run entirely on the phone, in English. |
| Not collected | Your location, contacts, photo library or camera, microphone audio, or any advertising identifier. Bunavi uses only the photo you pick or take for a baby's profile, and optional cry detection listens on your phone without recording, saving or sending the audio. |
| Copy on your phone | A small read-only copy of recent data, so the app works offline; it is cleared when you sign out. |
| Without an email address | Start as a guest: the account then has only a random identifier, plus a display name if you add one. Sharing a baby needs a free account. |
| Export | Free, in the app: Settings → Account & profile → Export my data gives a summary PDF (in English), spreadsheets (CSV) for each baby and one complete JSON file. |
| Deleting your account | In the app, Settings → Account & profile → Delete account works immediately; by email, within 30 days. A baby you share passes, with its history, to the caregiver who has been on it longest. |
| Who is responsible | Rostislav Antonovich, an independent developer in Bulgaria (EU), is the data controller. Your rights under the GDPR, and how to use them, are in the privacy policy. |
Which services outside the EU are involved?
Your baby's profiles, logs, health entries and photos are stored in the EU with Supabase. A few services Bunavi relies on are run by companies based in the United States, and the privacy policy names each one with what it receives:
- RevenueCat manages Bunavi Plus subscriptions. It receives your account identifier and App Store or Google Play purchase and renewal events.
- Sentry receives crash reports and app-health data, tied to a random identifier for your installation of the app and never to your account, and anonymous usage counts. They are designed to contain none of your records.
- Resend delivers Bunavi's emails. It receives your email address and the message; its sending infrastructure runs in the EU, in Ireland.
- Apple's push notification service delivers partner notifications on iPhone, such as “Ana logged a feed”. It receives your phone's push token, the notice's text (the partner's first name and the kind of entry), an internal code for the baby and the link the notice opens, never amounts, notes or other details of the entry.
- Google: Firebase Cloud Messaging delivers the same notices on Android and receives the same details, and the ML Kit scanner that reads invite QR codes in the Android app sends Google data about its use and performance, never the camera image or the code you scanned.
- Cloudflare hosts this website and receives your IP address and the details of each request. Cloudflare Web Analytics counts page views without cookies and without identifying you; the site's only cookie remembers your language.
Where personal data is handled outside the EU/EEA, it is protected by safeguards such as the European Commission's Standard Contractual Clauses. If you sign in with Apple or Google, that company verifies your identity, and the store you buy Bunavi Plus from bills it under its own terms.
Why does a tracker you share keep its log on a server?
Because two phones need to see the same log. When your partner logs a 3 a.m. feed, it reaches your phone through Bunavi's database in Frankfurt. You can still log with no signal; it syncs when you are back online.
So Bunavi is private and shared, not on-device only, and sharing needs a free account. If you want nothing stored on any server, an app that keeps everything on your phone fits better; the trade-off is that a second phone can't see the log live.
Four checks for any baby app
- Where are the records stored, and who answers for them? The privacy policy should say where the database runs and name a responsible company or person, with a country and a contact address.
- Which outside services receive anything, and what? A clear policy names each one and what it gets.
- Are there ads or advertising identifiers? Read what the policy says about ads, and the “Data Used to Track You” part of the App Store privacy label (on Google Play, the Data safety section).
- Can you export your records and delete your account yourself? Look for both in the app before you sign up, not after.
Bunavi's own answers are in the table above.
When Bunavi is not the right choice yet
- Your partner uses an Android phone. Bunavi is on iPhone; the Android version is in closed testing on Google Play, with no public date yet.
- You want to bring your history from another tracker. Importing isn't supported yet.
- You want an Apple Watch app. There isn't one.
- You need pediatrician PDF reports in your own language. They are part of Bunavi Plus, and they are in English.
- You want a sleep schedule. Bunavi shows a next-nap estimate (from 8 weeks, once there is about a week of sleep logs), not a schedule.
- You want an app with years of reviews. Bunavi launched in August 2026.
Questions parents ask
Can a baby tracker be private and still shared with my partner?
Yes: in Bunavi, sharing stays off until you invite someone, and in the app only the people who share that baby can see its records. Each invite code is single-use and expires after 7 days, sharing is free for you and up to 3 others per baby, and the baby's owner can remove anyone in Settings.
Is there a baby tracker that doesn't sell your data?
Bunavi never sells or rents your data and shares nothing with advertisers; it shows no ads and uses no advertising identifiers. For any app, read its privacy policy and the “Data Used to Track You” part of its App Store privacy label (on Google Play, the Data safety section).
Where is my baby's data stored, and does any of it leave the EU?
Bunavi stores your baby's records (profiles, logs, health entries and photos) in the EU, with Supabase in Frankfurt, Germany, encrypted in transit and at rest. A few services run by US companies handle purchases, crash reports, email, push notifications and the bunavi.app website, and Bunavi's privacy policy names each one with what it receives.
Is my baby's log used to train AI?
Not in Bunavi: nothing from your baby's log is sent to an AI service or used to train AI, and there is no chatbot and no cloud AI. On iPhones that support Apple Intelligence (iOS 26 or later), a few optional writing touches run entirely on the phone, in English.
Can I use a baby tracker without giving my email address?
Bunavi lets you start as a guest, without an email address; the guest account has only a random identifier, plus a display name if you add one. Your records are still stored in Bunavi's EU database, but without an account you may lose them if you delete the app or switch phones, and sharing a baby needs a free account.
Can I export my baby's data and delete my account myself?
In Bunavi, yes: both are in the app, and exporting is free. Settings → Account & profile → Export my data gives you a summary PDF (in English), spreadsheets (CSV) for each baby and one complete JSON file, and Delete account on the same page removes your account immediately. A baby you share passes, with its history, to the caregiver who has been on it longest.
