Privacy Policy

The short version: Plumi is built to keep your baby's data on your device. We don't require an account, we don't run third-party analytics, we don't show ads, and we never sell your data. The only times anything leaves your phone are optional end-to-end-encrypted sync and partner sharing (Pro) and an optional iCloud backup. This policy explains the details.

1. Who we are

This Privacy Policy describes how Plumi ("Plumi", "we", "us") handles information in connection with the Plumi mobile application and the website at plumi.app (together, the "Service"). If you have any questions, contact us at privacy@plumi.app.

2. Data stored on your device

The information you enter into Plumi — your baby's profile, logs (feeds, diapers, sleep, growth, health events, milestones), checklists, shopping list, notes and photos — is stored locally on your device. We do not have a copy of it on our servers, and we cannot read it.

3. Information we do not collect

• We do not require you to create an account to use the core app.
• We do not include third-party advertising or advertising identifiers.
• We do not embed third-party analytics or tracking SDKs.
• We do not track you across apps or websites, and we do not sell or rent personal data.

4. Sync, partner sharing & backup

With Plumi Pro you can sync your data across your own devices and share a baby's record with a partner or caregiver. This sync is end-to-end encrypted: your data is encrypted on your device with a key that stays on your devices, and our servers only ever hold ciphertext we cannot read. The encryption key is never sent to us. Sharing is per child: you choose which children each person can see and whether they can edit or only view. A child you don't share with someone is never delivered to them in any form; they never receive that child's encryption key or data.

You can also keep a local iCloud Drive backup through your own private iCloud account, governed by Apple's Privacy Policy. Sync, sharing and backup are all optional and off until you turn them on. Other than these, nothing leaves your device.

5. Accounts and subscriptions

You only create an account — using Sign in with Apple or Google — if you choose to subscribe to Plumi Pro, so your subscription can be linked across your devices. In that case we store a minimal account record (such as a provider identifier and, where provided, an email address) and your subscription status. Payments are processed by Apple through the App Store; we do not receive your card details.

6. How information is used

• To provide the Service and the features you use.
• To operate and secure end-to-end-encrypted sync and partner sharing for users who turn them on.
• To manage Pro subscriptions for users who choose to subscribe.
• To respond to you when you contact us.

7. Sharing

We do not sell your personal data. We share information only with service providers who help us operate the Service (such as Apple for payments and iCloud), and only as needed for those purposes, or where required by law.

8. Data retention & deletion

On the free plan, log entries older than one year are automatically removed from your device; Plumi Pro keeps your full history. Other data stored on your device remains until you delete it or remove the app. You can export your data to CSV at any time. If you contact support or subscribe, we retain related records only as long as needed for those purposes or as required by law. To request deletion of any account information, email privacy@plumi.app.

9. Children

Plumi is designed for parents and caregivers to record information about their own children. It is intended for use by adults (18+). The app is not directed to children, and children should not use it directly.

10. Security

On-device data is protected by your device's built-in security. Sync and partner sharing are end-to-end encrypted, so data in transit and on our servers stays ciphertext we can't read. No method of storage or transmission is perfectly secure, but we take reasonable measures to protect your information.

11. Your rights

Depending on where you live, you may have rights to access, correct, or delete personal information we hold about you. Because most data stays on your device, you can exercise many of these directly in the app. For anything else, contact privacy@plumi.app.

12. Changes to this policy

We may update this Privacy Policy from time to time. If we make material changes, we will update the "Last updated" date above and, where appropriate, provide additional notice.
