Privacy Policy
Last updated: November 6, 2026
This policy explains what Nanita collects, why, and what you can do about it. Nanita ("the app") is published by CloudArbitration LTDA ("we", "us"), the same company behind Nanu, Kaha Trainer and DietCoach. You can reach us at info@kahatrainer.com.
1. The short version
You can use Nanita without an account: in that case your pregnancy data stays only on your phone. If you create an account, we store your pregnancy, logs and photos on our servers so they sync between devices and can be shared, in part, with the partner you invite. Information about your pregnancy is sensitive health information: we use it only to run the app for you. It is never sold, never used for advertising and never sent to analytics. We collect anonymous usage statistics and crash reports. The free version shows a few banner ads on content screens, personalized only if you allow it.
2. Using the app without an account
Nanita works fully in guest mode. Without an account, your pregnancy, every log, your diary, lists and photos are stored only on your device; nothing about your pregnancy is sent to our servers. The trade-off is that the data does not sync to other devices, cannot be shared with a partner and is lost if you delete the app. Usage statistics, crash reports and ads (sections 3.5 to 3.7) still apply in guest mode.
The widgets and the contraction Live Activity read your data from the device itself. The PDF summaries (for your doctor and your birth plan) are created on the phone and go only where you choose to share them.
3. Data we collect
3.1 Account information — shared with Nanu
An account is optional. You can create one with an email and password, with Sign in with Apple or with Sign in with Google. We collect your email address and your name. With Sign in with Apple, we receive whatever Apple sends us — which may be a private relay address instead of your real email. Passwords are handled by our authentication provider and are never visible to us.
Nanita and our baby app, Nanu, share the same backend and the same account. Signing in to either app with the same account gives you access to the data you created in both.
3.2 Your pregnancy data
When you are signed in, we store what you record, which is the reason the app exists:
- Your pregnancy: due date and how it was calculated (last period, due date, ultrasound or IVF transfer), whether it is your first pregnancy, your height and pre-pregnancy weight if you enter them, and the baby's name if you choose one.
- Health logs: symptoms, mood, weight, bump size, blood pressure, blood sugar, supplements, water, sleep and exercise, kicks, contractions, prenatal appointments, exams, vaccines and ultrasounds.
- Your diary and notes, the list of baby names (with votes), and your checklists (hospital bags, baby gear, birth plan).
- Photos you attach — bump, ultrasound, diary and exam photos — stored in a private storage area of our database provider.
- If you record it: the birth (baby's name, date and time, sex, weight, length, type of birth and gestational age) or the end of the pregnancy.
This information is provided by you and is used only to show it back to you, to the partner you invite (as described below) and, after the birth, in Nanu.
3.3 Partner mode
You can invite one or more adults — usually your partner — with a 6-digit code that is valid for 7 days. A partner can see the week and due date, appointments, kicks, contractions, ultrasounds, bump measurements and photos. They can vote on baby names and tick items on checklists, but they cannot edit your pregnancy or your logs. They never see your symptoms, mood, weight, blood pressure, blood sugar, diary, exams or exam photos. We record who follows each pregnancy, and you can see their name and email in the list of people following. You can remove a partner at any time, and a partner can stop following on their own.
3.4 When the baby is born
When you tap "The baby was born" while signed in, Nanita creates the baby's profile in Nanu with the birth details above, and the partners following your pregnancy become the baby's caregivers there. Nothing is passed to Nanu if you are using the app without an account.
3.5 Usage analytics and crash reports
To understand which screens are useful and to fix what is broken, the app records product events in our own analytics table: a random identifier generated on your device at install, the screens viewed, the app version, actions such as "a log was saved" or "a timer started", ad decisions (whether an ad was shown or skipped, and why) and purchases. Events never include health data — not the content of a log, not even its type (symptom, weight, blood pressure…), and not your week of pregnancy. That identifier is not linked to your account or your email, and it is recreated if you delete and reinstall the app.
We also use Google Firebase Analytics, which receives the same events for aggregate statistics, and Firebase Crashlytics, which sends a crash report (device model, iOS version, app version and the technical state of the app when it crashed) if the app closes unexpectedly. Your pregnancy data is not included in either.
3.6 Advertising
The free version may show banner ads served by Google AdMob, only on content and history screens: Weeks, topics and articles, Diary and chart details. Never on Today, the kick counter, the contraction timer, warning signs or while you are logging. Depending on your choices and region, AdMob may process your device's advertising identifier (IDFA), general device and network information (including an approximate location derived from your IP address) and ad interaction data. Your health and pregnancy data are never shared with AdMob or used to choose ads.
Ads are personalized only with your permission: on iOS, through Apple's App Tracking Transparency prompt; in the European Economic Area, the United Kingdom and Switzerland, also through Google's consent form. If you decline, the app works exactly the same and ads are simply less relevant. The "No Ads" plan removes ads altogether. Google's handling of this data follows its own policies; see How Google uses information from sites or apps that use our services.
3.7 Purchases
Purchases are processed by Apple through the App Store. Apple sends our server notifications about your transaction (which plan, whether it is active, renewal and expiry) so we can remove ads on every device of your account. We never see your card or payment details.
3.8 Notifications
The morning update and appointment reminders are scheduled locally on your device. For notifications sent by us (for example, a new week starting), we use Firebase Cloud Messaging: we store your device's push token, time zone, language, app version and which kinds of notification you opted into, so we can send them at a reasonable hour and in your language. They never contain your health logs.
3.9 What we do not collect
- We do not ask for your location.
- We do not access your contacts, microphone or the Apple Health app.
- We do not collect payment card details.
- We do not access your photo library beyond the photos you choose to attach.
4. Why we process it
| Purpose | Data | Legal basis (LGPD / GDPR) |
|---|---|---|
| Provide the service: store, sync and share your pregnancy logs and photos | Account, pregnancy data, logs, photos, partner memberships | For health data, your explicit consent, given when you create the account and record it; otherwise performance of a contract |
| Create the baby's profile in Nanu after the birth | Birth details, partner memberships | Your explicit consent, given when you record the birth |
| Remove ads for paid plans | Purchase status | Performance of a contract |
| Send the notifications you opted into | Push token, time zone, language, opt-ins | Consent |
| Understand product usage and fix crashes | Anonymous usage events, crash reports | Legitimate interest |
| Support the free version with advertising | Advertising identifier, ad interactions | Consent, where required |
Information about a pregnancy and a birth is sensitive personal data. We use it only to provide the app's features to you and to the people you choose — never for advertising, never for analytics, and we never sell it.
5. Who we share it with
We do not sell personal data. We share it only with the providers that make the app work:
- Supabase (Supabase Inc.) — hosts our database, photo storage and authentication, in the United States (us-east-1). Processes your data on our instructions.
- Google — Sign in with Google, Firebase Analytics, Firebase Crashlytics, Firebase Cloud Messaging and AdMob, as described above. None of them receives your pregnancy data.
- Apple — provides Sign in with Apple, in-app purchases and push notification delivery.
- The partners you invite — they see the parts of your pregnancy listed in section 3.3.
6. International transfers
Our database is hosted in the United States, and our other providers may operate infrastructure outside your country. Where required, transfers rely on the European Commission's standard contractual clauses or an equivalent mechanism offered by the provider.
7. How long we keep it
Account and pregnancy data are kept while your account exists. When you delete a log, its photo is deleted from storage too. Data kept in guest mode lives on your device until you erase it or delete the app. Anonymous usage events are retained in aggregate; because they are not linked to your identity, they cannot be isolated and removed per person. Crash reports are kept by Firebase for a limited period.
8. Your rights and deleting your data
Depending on where you live, you may have the right to access, correct, export, restrict or delete your personal data, to object to processing, and to withdraw consent at any time. To exercise any of these, write to info@kahatrainer.com from the address associated with your account. We answer within 30 days.
Deleting your account. In the app, go to Profile → Delete account. This removes, immediately and permanently, your account, the pregnancy you own with all its logs, lists and photos, and your partners' access to it. If you follow someone else's pregnancy, only your access is removed. Because the account is shared, this also deletes your account in Nanu, including the babies you own there. You can also ask us to delete it by email.
Guest mode. To erase data kept without an account, use Profile → Erase all data or delete the app from your phone.
If you are in the European Economic Area or the United Kingdom, you also have the right to lodge a complaint with your local data protection authority.
Practical controls — tracking, notifications, partner access — are listed on Your Privacy Choices.
9. Security
Data in transit is encrypted with TLS. Access to the database is restricted by row-level security rules, so an account can only read the pregnancies it owns or was invited to, and a partner only the kinds of log listed above. Photos are kept in a private storage area, not on public links.
10. Children
Nanita is made for adults: pregnant people and their partners. It is not directed at children and is not meant to be used by them. If you believe a child has created an account, write to us and we will delete it.
11. Health disclaimer
Nanita is a log and organizer with general information. It is not medical advice, does not diagnose or treat anything, and does not replace your doctor or midwife. In an emergency, call your local emergency number. See the Terms of Use.
12. Changes to this policy
If we change this policy, we will update the date at the top and, for changes that matter, tell you in the app before they take effect.
