Privacy Policy

Littlest Pty Ltd (ACN 690 052 709), Brisbane, Queensland, Australia

Last updated: 23 October 2026

Littlest is a baby tracking and parenting support app for iOS and Android, made by Littlest Pty Ltd. This policy explains what we collect, why we collect it, who helps us handle it, and the choices you have.

We handle personal information in line with the Australian Privacy Act 1988 and the Australian Privacy Principles. If you are in the European Economic Area or the United Kingdom, please also read the section near the end written for you.

Who uses Littlest

Littlest is for parents and carers aged 18 or over. Children never use the app themselves. Parents enter information about their children, and we treat information about a child as sensitive information.

What we collect

About you

• Your name and email address.
• Your stage, such as trying to conceive, pregnant, or parenting.
• If you use those features: cycle and basal body temperature data, and mental wellbeing check-ins.
• Optional details you choose to add, such as a midwife or maternity unit phone number, and salary figures if you use the leave planner.
• Coarse location only: postcode or suburb, and country. We do not collect your street address or precise GPS location.

About your child

• Name, date of birth or due date.
• Feeds, sleep, nappies, growth, milestones, medicines, symptoms and temperatures that you log.
• Photos and videos you upload.

What you share with the AI coach

• Chat messages you send, transcripts of voice conversations, and any image you attach to a chat message, together with the care details needed to answer you.

AI support is optional. Before your first AI conversation, the app asks you to agree to the processing described in its AI notice. You can use tracking without agreeing. Journal entries remain private unless you choose to share an entry with the coach. Plans store the goals, notes, check-ins and attachments you choose to add. These plans and their attachments are private to your account; shared care tools keep their own sharing controls. When you ask the coach for help with a plan, relevant plan details are used to answer you.

Technical information

• Crash and error reports.
• If you leave analytics switched on, counts of screens viewed and features tapped, plus coarse bands such as an age band. Never the content of your logs, chats or photos.

We do not sell your information. We do not use it for advertising. Littlest contains no advertising software kits and no advertising identifiers, and we do not track you across other apps or websites.

Why we collect it

To create and run your account; to show and organise your child's record; to answer your questions through the AI coach; to send the reminders and notifications you turn on; to keep the app working, secure and free of bugs; to manage your Littlest Plus subscription; to send requested sign-in and service messages; and, if you choose, to send Littlest tips and updates that you can unsubscribe from at any time.

Who helps us handle it

The companies below process information for Littlest under contract, on our instructions only. They are not permitted to use it for their own purposes, to sell it, or to use it for advertising.

• Google Firebase (sign in, database, file storage, server functions, push notifications). Your account data, child records, photos and videos are stored in Australia, in Google's australia-southeast1 region.
• Google Analytics for Firebase, for usage events such as screen and tap counts and coarse bands, never content. Analytics is on by default. You can switch it off in Settings > Confidentiality.
• Firebase Crashlytics and Sentry, for crash and error reports. These carry an account identifier and no content.
• Google BigQuery, for product events with an account identifier. Stored in Australia.
• Customer.io, for requested sign-in emails and optional marketing email. Marketing is off until you opt in. If you opt in, we send your email address, first name, coarse lifecycle and age bands, number of babies, plan state, activity indicators and consent flags. Waitlist signup gives permission for launch updates only, not an ongoing tips subscription. Marketing emails have an unsubscribe link, and you can also turn off Emails and tips in Settings. We do not send connected health readings or private plan content to Customer.io. Our Customer.io workspace is hosted in the European Union.
• RevenueCat, for subscription status keyed to your account identifier, including receipts from Apple and Google.
• Anthropic, OpenAI and Google, as AI model providers. Chat messages, voice transcripts, an image attached to a chat message, and the care details needed to answer are sent through Littlest's own gateway. Processed in the United States.
• Fireworks AI, which creates numerical representations of memory and retrieval text so the coach can recall context. United States.
• Deepgram, which turns live voice audio into text. United States.
• Cartesia, which turns reply text into speech. United States.
• Langfuse, which stores redacted traces of model calls so we can debug quality problems. United States.
• Apple and Google speech recognition, when you use the dictation microphone in the chat bar. This uses the speech service built into your device or platform.
• Google Calendar, read only, and only if you choose to connect it. We read busy blocks or event titles, which are sanitised on your device before use. Our use of information received from Google APIs follows the Google API Services User Data Policy, including the Limited Use requirements.
• Apple App Store and Google Play, for payments. Littlest never sees your card details.

We may also disclose information if the law requires it, or to protect someone's safety.

Information held or processed overseas

Your account data, child records, photos and videos are stored in Australia. AI, speech, crash reporting and billing providers process information in the United States. Our email tool is hosted in the European Union. Where our providers process data outside Australia we rely on their contractual safeguards.

Sharing with a partner or caregiver

You can invite a partner or caregiver. They see the child record you choose to share with them, and nothing else. There is no public feed and no social sharing inside Littlest.

How we keep it safe

Information is encrypted in transit. Access to your records is controlled by Firebase security rules so that only you and the people you invite can read them. Littlest does not store passwords: you sign in with an email code, with Google, with Apple, or you can start anonymously.

No system is perfectly secure, so please keep your email account and device secure too.

How long we keep it

We keep your information for as long as your account is open, then delete it as described below. Some records we must keep for longer, such as payment and tax records we are required by law to retain for the statutory period, and anonymised aggregate statistics that no longer identify anyone.

Deleting your account

You can delete your account in the app, under Settings > Delete account, or Confidentiality > Delete. You confirm the deletion, and you may be asked to sign in again first.

We delete your profile and login, every child profile you own, all logged observations, your chat and voice history, the coach's memories, milestones, private Plans and their attachments, connected health summaries and consent records, and the photos and videos you uploaded. We also delete your subscription record at our billing processor, your email marketing profile and your analytics records. If you signed in with Apple, we revoke the Sign in with Apple tokens.

Two things stay behind. A child profile that a partner or caregiver also cares for stays with them and is simply unlinked from you, and your photos of that child stay with the child's record. And we keep the legal records and anonymised aggregates described above.

If you cannot use the in-app option, email admin@littlest.ai from your account email address and we will action it within 30 days.

Deleting your Littlest account does not cancel an App Store or Google Play subscription. Manage or cancel that subscription separately in your store account settings.

Children's information

We collect information about children from their parents and carers, never from children. We treat it as sensitive information, we never use it for advertising, and we never sell it.

Health information

Littlest gives general parenting, feeding and wellbeing information. It is not medical advice, and nothing in the app is a diagnosis or a treatment plan. Some safety features point you to your local emergency number. Always speak to a health professional about your child's health, and call emergency services in an emergency.

Optional Apple Health and Health Connect connection

If you connect a health app, Littlest asks for read-only permission for your sleep, steps, resting heart rate and heart rate variability. A manual sync reads available measurements from the previous 24 hours and summarises them on your phone. Littlest does not write to Apple Health or Health Connect, and reading permission alone does not upload these measurements to our servers.

You separately choose whether to use the summary in Littlest AI. If you turn this on, we store your latest summary in your private account and may send it with the context needed for your question to the AI providers listed above, through Littlest's gateway. It can inform your private text conversations, voice replies and Home guidance. It is not shared with your partner or added to the shared child record.

We retain the latest summary, not the underlying health samples or a health history. The summary stops being used for new AI requests after 24 hours and is scheduled for deletion; physical deletion may take longer. Turning AI use off or disconnecting clears the saved summary and private Home guidance when the app can connect. If you are offline, the withdrawal is queued until connectivity returns. Past conversations may still contain information you chose to share. You can also revoke health permissions in your device settings.

Connected health information is used only to provide the health and wellbeing features you choose. It is not used for advertising, marketing, data brokerage or training general-purpose AI models, and is not sent to Customer.io. Our use of information received from Health Connect follows the Health Connect permissions policy, including its Limited Use requirements.

Your choices

• Analytics: switch off in Settings.
• Marketing email: optional. Unsubscribe from a marketing email or turn off Emails and tips in Settings.
• Calendar: connect or disconnect at any time.
• Notifications: control in Settings and in your device settings.
• Access and correction: most information can be viewed and edited directly in the app. For anything you cannot reach, email admin@littlest.ai and we will help you access or correct it.

If you are in the EEA or UK

We rely on these lawful bases: performing our contract with you, to run your account and provide the app and your subscription; your consent, for marketing email and for analytics; and our legitimate interests, for security, fraud prevention and keeping the service reliable.

You have the right to access, correct, erase, restrict and object, the right to portability, and the right to withdraw consent at any time. Email admin@littlest.ai.

Our providers listed above process some data outside the EEA and the UK. Where that happens we rely on their contractual safeguards, including the European Commission's standard contractual clauses where the provider offers them.

Complaints

If you are unhappy with how we have handled your information, email admin@littlest.ai and we will respond. If you are still not satisfied, you can complain to the Office of the Australian Information Commissioner at oaic.gov.au. In the EEA or UK you can also complain to your local data protection authority.

Changes to this policy

If we change this policy we will update the date at the top and, for significant changes, tell you in the app or by email.
