LunaFlow Partner is an optional LunaFlow+ feature that lets you share a small summary with one person you choose, such as a partner or co-parent. Nothing is shared unless you turn it on, tick what to share, and approve the person who joins.
What can be shared
Only the categories you tick, which may include: cycle phase and expected period dates, fertile window estimates, suggested pregnancy test dates, pregnancy or postpartum stage, a one-line mood and symptom summary, and upcoming appointment dates (with titles only if you choose). Private intimacy logs, journal entries and personal notes can never be shared.
End-to-end encryption
What you share is encrypted on your device and can only be decrypted on your partner's device. The encryption keys stay on your devices. LunaFlow's servers store only encrypted data that we cannot read. This also applies to your partner's first name, support messages, weekly check-in answers and shared checklists.
We never sell shared information and never use it for advertising.
What our servers can see
To connect you, our servers hold: the two account identifiers and email addresses, that the accounts are connected, the connection status and dates, public encryption keys, a one-way scrambled (hashed) copy of the invite code, encrypted data with its size and update time, and push notification tokens. When a notification is needed, our servers know the kind of event (for example, that support was sent), but not its content.
Notifications
If you allow notifications, a push token for your device is stored and notifications are delivered through Expo and Apple's push notification service. Notification previews are always generic and never include fertility, pregnancy or health details.
Partner accounts
Partner accounts are free and are used only to view what has been shared with them. A partner account needs an email address. LunaFlow Partner does not require cloud sync to be turned on.
Stopping and deletion
You can pause sharing, or stop it at any time. When you stop, either with a notification to your partner or quietly, everything shared through the connection is deleted from our servers. Your partner can also leave at any time, with the same result. Deleting either account also ends the connection and deletes what was shared. Support messages are kept for up to 30 days, and the shared summary is replaced each time it updates.
If you ever feel unsafe with the person you share with, you can stop quietly at any time. If you are in danger, contact emergency services.
Some service providers may store or process data outside Australia.
Where this occurs, we take reasonable steps to ensure information is handled in accordance with applicable privacy obligations and industry security standards.
We will update this policy if our international data handling practices change. Transparency around overseas disclosures is an important privacy requirement.
LunaFlow+ subscriptions may be processed through:
Subscription providers may process payment information directly.
LunaFlow does not store your full payment card information.
We may collect limited analytics and diagnostic information to:
Where possible, analytics are anonymised or aggregated.
You may request access to personal information we hold about you.
You may also request correction of inaccurate information.
Requests can be submitted through our support channels.
We will respond within a reasonable period and in accordance with applicable laws. Australian privacy guidance generally recognises rights of access and correction.
We retain information only for as long as reasonably necessary to:
When information is no longer required, we will take reasonable steps to delete or de-identify it.
LunaFlow is intended for adults and older teenagers capable of managing their own wellness information.
Parents or guardians should supervise use where required by law.
You may request deletion of your account and associated personal information.
Where legally permitted, we will delete or de-identify your information within a reasonable timeframe.
Certain records may be retained where required for legal, regulatory, security, or operational purposes.
If you believe we have breached your privacy, please contact us first so we can investigate and resolve the issue.
We will respond within a reasonable period.
If you are not satisfied with our response, you may contact the Office of the Australian Information Commissioner (OAIC).
We may update this Privacy Policy from time to time.
When significant changes occur, we will notify users through the app or by other appropriate means.
The latest version will always be available within LunaFlow.
