Privacy Policy
- Without an account, your baby’s logs stay on your phone. We don’t receive them.
- If you create an account, we store your email and your logs so they’re backed up and shared with the people you invite.
- No ads, no advertising or analytics trackers, and we never sell or rent your data.
- You can export or delete everything at any time.
Who we are
This policy covers the Nuvle mobile app and this website (together, “Nuvle”, “we”, “us”). Nuvle is a baby sleep tracker that predicts nap and bedtime windows from the information you log. If you have questions, contact us at .
What we collect
Information you enter in the app
- About your baby: name or nickname, birth date (and due date if born early), an avatar emoji, typical wake time and nap count.
- Logs: sleeps, feeds, diapers and notes, with times, durations and details you choose to add.
- Caregivers: first names and roles (for example “Sam, partner”) so each log shows who added it.
- Parent check-ins: stored only on your phone. They are never uploaded or shared.
Without an account, all of this is stored only on your device. We do not receive it.
If you create an account
- Email address, used to sign in with a one-time code and to identify your account.
- A display name, if you give one.
- Your logs and baby details (listed above, except check-ins), stored in our database so they are backed up and synced to the people in your household.
- Household membership and invites: who belongs to your household, their role, and invite codes you create.
Purchases
If you subscribe to Nuvle Plus, payment is handled by Google Play or the Apple App Store. We never see your card details. We receive subscription status (for example “trial” or “active”), product, purchase and renewal dates, and an anonymous app user ID — or your account ID if you are signed in.
Technical information
Our service providers receive standard technical information needed to run the service, such as IP address, device type, operating system and app version, when the app talks to them (for example to sign in, sync or check a subscription).
What we don’t collect
We don’t use advertising SDKs or third-party analytics trackers. We don’t collect your location, contacts, photos, microphone or camera data. Nuvle doesn’t use your data to train AI models.
How we use your information
- To provide the app: predictions, history, insights, plans and reminders. Predictions are calculated on your device.
- To back up your logs and sync them with the caregivers you invite.
- To sign you in and keep your account secure.
- To provide and restore Nuvle Plus subscriptions.
- To answer your support requests.
Reminders are scheduled locally on your phone; we don’t send them from a server.
Who we share it with
We never sell or rent your data, and we don’t share it for advertising. We share it only with:
- People you invite. Members of your household can see and add to your baby’s logs. Anyone who has the invite code you send can use it to join until it expires, so share it only with the person you mean.
- Service providers that process data on our behalf, under contracts that limit how they use it:
| Provider | What for | Data |
|---|---|---|
| Clerk | Sign-in with email codes | Email address, account ID, sign-in sessions, technical information |
| Neon | Database hosting (EU, Frankfurt) | Account and household data and synced logs |
| RevenueCat | Subscription management | App user ID, purchase and subscription status, device information |
| Google Play / Apple App Store | Payments and app distribution | Handled under Google’s and Apple’s own privacy policies |
| Vercel | Hosting this website | Standard web server logs |
We may also disclose information if required by law, or to protect the rights, safety and security of our users or the public.
Children’s privacy
Nuvle is for parents and caregivers aged 18 or over; it is not directed to children. The app stores information about a baby — such as name, birth date and sleep logs — that a parent or caregiver chooses to enter. That information is controlled by the parent: it can be exported, edited or deleted at any time. We don’t knowingly collect personal information from children. If you believe a child has given us information, contact us and we will delete it.
How long we keep data
- Data on your device stays until you delete it or uninstall the app.
- Account data is kept while your account is active. When you delete your account, we delete your account, your logs and your household data (if you are its last member) from our live database right away. Copies in our database’s short-term recovery history expire within 7 days.
- Subscription records may be kept by our providers and app stores as required for tax and accounting.
Your choices and rights
- Export: download all your logs as CSV in the app (More → Export).
- Correct: edit or delete any entry, baby or caregiver in the app.
- Delete: delete your account in the app (More → Account → Delete account), clear this phone with Delete all data, or request deletion on the web.
- Leave a household or cancel invites at any time.
- Notifications: turn reminders off in the app or in your phone’s settings.
Depending on where you live (for example in the EU, the UK or California), you may have rights to access, correct, delete or port your data, and to object to or restrict certain processing. Email and we will respond within 30 days. You may also complain to your local data protection authority.
Legal bases (EEA and UK)
We process account and log data to provide the service you asked for (performance of a contract), keep the service secure (legitimate interests), and handle purchases and records (legal obligations).
International transfers
Our database is in the European Union. Some providers (such as Clerk and RevenueCat) process data in the United States. Where required, transfers rely on safeguards such as the EU Standard Contractual Clauses.
Security
Data is encrypted in transit (HTTPS). Database access is limited to members of your household by row-level security, and sign-in uses one-time email codes, so there are no passwords to leak. No system is perfectly secure, but we work to protect your data.
Changes
If we change this policy, we will update the date above, and for significant changes we will tell you in the app.
