At Liko, we understand that your baby's information is precious and personal. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our mobile application. We are committed to protecting your privacy and being transparent about our data practices.
When you create an account and use Liko, we collect information you voluntarily provide:
| Data Type | Examples | Purpose |
|---|---|---|
| Account Information | Email address, password, name | Account creation and authentication |
| Baby Profile Data | Baby's name, date of birth, gender, profile photo | Personalized tracking experience |
| Tracking Data | Sleep sessions, nursing sessions, bottle feedings, pumping sessions, diaper changes, solid food entries, growth measurements | Core app functionality and reporting |
| Health-Related Data | Body temperature readings and medicine doses you log for your baby | Health tracking and history at your request |
| Photos | Baby profile photo you choose from your photo library | Personalizing the profile, home screen and widget |
| Sharing Data | Email addresses of caregivers you invite, and the access you grant them | Letting a partner or caregiver share a baby's records |
| Preferences | Notification settings, theme preferences, measurement units | Customized user experience |
When you use Liko, we automatically collect certain information:
Liko supports two ways to sign in: an email address and password that you choose, or Sign in with Apple. If you use Sign in with Apple, we receive the identifier Apple issues for you and the email address you elect to share — including Apple's private relay address if you choose to hide your real one. We do not offer Google sign-in and receive nothing from Google.
Liko asks for a permission only when a feature needs it, and the app works without them:
We use the collected information for the following purposes:
Liko uses trusted third-party services to provide certain functionality. Each service has its own privacy policy governing their use of your data:
| Service | Purpose | Data Shared |
|---|---|---|
| Supabase | Authentication and database storage | Account info, all tracking data |
| PowerSync | Offline storage and synchronization between your device and our database | Your tracking data, in transit and cached on device |
| Bugsnag | Crash reporting and diagnostics | Device info, crash logs, and your user ID, email address and display name |
| PostHog | Analytics, product improvement and session recordings | Usage events and screen recordings, linked to your user ID |
| RevenueCat | Subscription management | User ID, purchase history |
Liko does not use advertising networks and shows no third-party ads. We do not use Google Analytics, Facebook SDK, or any advertising or data-broker SDK.
Liko lets you share a baby's records with a partner, family member, or other caregiver. This sharing only ever happens because you start it:
Your data is stored securely using Supabase's cloud infrastructure with the following measures:
Liko is offline-first. Your entries are written to a local database on your device (PowerSync) and synced with our servers when you're online, so the app keeps working without a connection. Your baby's profile photo is also cached in a shared app container so the Liko home screen widget can display it without a network request. Local data is protected by your device's security features (Face ID, Touch ID, passcode), and removing the app removes it.
We implement industry-standard security measures including:
We retain your data for as long as your account is active or as needed to provide you with our services. Specifically:
When you delete your account, we will delete or anonymize your personal information within 30 days, except where we are required to retain certain information for legal or legitimate business purposes.
Depending on your location, you may have certain rights regarding your personal information:
Request a copy of the personal information we hold about you
Request correction of inaccurate personal information
Request deletion of your personal information
Request your data in a portable format
Request restriction of processing in certain circumstances
Object to processing for direct marketing purposes
To exercise any of these rights, please contact us at click to reveal email. We will respond to your request within 30 days.
Liko is designed for use by parents and caregivers to track their children's development. The App is not intended for direct use by children. We collect information about babies solely from their parents/guardians for the purpose of providing baby tracking services. We do not knowingly collect personal information directly from children under 13.
Your information may be transferred to and processed in countries other than your country of residence. These countries may have different data protection laws. When we transfer data internationally, we ensure appropriate safeguards are in place to protect your information in accordance with this Privacy Policy.
With your permission, Liko shows notifications for:
You can manage notification preferences in your device settings or within the App. Disabling notifications may affect certain features.
We use PostHog to understand how people use Liko so we can fix problems and decide what to build next. We record events such as which screens you open, which features you use, and when errors occur. Once you sign in, these events are linked to your account identifier rather than being anonymous, which lets us reproduce a problem you report. Signing out unlinks the association on your device.
We use recordings solely to diagnose bugs and improve the interface, access to them is limited to our team, and they are not sold or used for advertising. If you would prefer that we do not record your sessions, email us at click to reveal email and we will exclude your account and delete any recordings we hold for it.
Bugsnag collects a report when the App crashes or hits an unexpected error. A report contains device information (model, OS version), the technical state of the App at the moment of the crash, and — if you are signed in — your user identifier, email address and display name, so we can follow up on an issue you reported. Crash reports do not contain your baby's tracking entries or photos.
If you are a California resident, you have additional rights under the California Consumer Privacy Act (CCPA):
If you are located in the European Economic Area (EEA), you have rights under the General Data Protection Regulation (GDPR). Our legal bases for processing your information include:
Temperature readings and medicine doses you record are data concerning health, which the GDPR treats as a special category. We process them on the basis of your explicit consent, given by choosing to enter them: the App works fully without them, and you can delete any entry at any time. Our servers are operated for us by Supabase; where data is transferred outside the EEA we rely on the European Commission's Standard Contractual Clauses.
You may withdraw consent at any time where processing is based on consent, without affecting the lawfulness of processing before withdrawal.
We may update this Privacy Policy from time to time. We will notify you of any changes by:
We encourage you to review this Privacy Policy periodically. Your continued use of the App after any changes indicates your acceptance of the updated Privacy Policy.
The App may contain links to third-party websites or services (such as articles or recipes). We are not responsible for the privacy practices of these third parties. We encourage you to read the privacy policies of any third-party services you access through our App.
In the event of a data breach that affects your personal information, we will:
