Security and privacy
Your family’s information, looked after properly
Halven holds your children’s medical details, your schedule and your household finances. That deserves proper care, and it deserves to be explained plainly rather than buried in a policy.
Reliability
Why you can rely on what you see
Two people are working from the same information. It has to be right, and it has to be the same on both screens.
- Nothing changes behind your back
- Messages, check-ins and payment history stay as they were written, so neither of you has to re-read a thread wondering whether it moved.
- Times you can trust
- The time on something comes from us, not from either phone — so a device with the clock set wrong cannot put the wrong time on anything.
- Removed things stay visible
- An expense that should not have been added can be voided. It stays in the list, struck through, with the reason — so the balance makes sense to both of you afterwards.
- Summaries say what they contain
- Every PDF opens with a page saying what is included and the period it covers, so it still makes sense when you open it again next year.
- Both parents see the same thing
- There is no filtered view and no partial version. What you see is what your co-parent sees, which removes an entire category of disagreement before it starts.
- A history you can both read
- What you have agreed, who else has access, and any summaries prepared are all listed where both parents can see them.

This summary covers everything in your family for the period above. Both parents can prepare the same one, and both are told whenever a summary is generated.

Every summary opens with a page like this, so it is clear what is inside it.
Security
How the data is protected
Standard practice, applied properly, is most of the job. Here is what is actually in place.
- Encrypted, coming and going
- Everything is encrypted on its way to us and while it sits with us, and it is backed up every night.
- We cannot read your password
- Passwords are stored scrambled, using the method security people currently recommend. Nobody here can look yours up.
- Your files stay private
- Receipts, documents and photos are never public and never guessable. Only the people in your family who are meant to see a file can open it.
- Sensitive numbers stay hidden
- Medicare and NHI numbers stay covered until you tap to reveal them, so they are not sitting on screen when you hand someone your phone.
- Nobody sees another family
- Every family is sealed off from every other one. There is no shared view and no way to end up looking at somebody else’s children.
- Built for New Zealand and Australian rules
- We work to the Privacy Act 2020 in New Zealand and the Australian Privacy Principles, rather than treating either as an afterthought.
Privacy
What we do not do
In this category, the restraint matters more than the features.
- Location only at the tap
- A check-in captures your position at the moment you press the button. The app never tracks in the background, holds no continuous location permission, and has no history of where you have been.
- No ads, ever
- No advertising, no ad networks, no cross-app tracking, no data sold or shared with brokers. There is no version of this product where a custody arrangement becomes ad targeting.
- As little about the children as possible
- Children do not have accounts or email addresses, and nothing in the app is aimed at them. We hold what is needed to run your calendar and your list of costs, and no more.
- Tone help leaves no trace
- Tone check and rewrite results are visible only to you, are never stored, and your co-parent is never told the tool ran.
- Professionals are visible and time-boxed
- Anyone you bring in to help — a mediator, a lawyer, a parenting coach — gets read-only access to the parts you choose, for a set period, and it ends by itself. Both parents are told.
Leaving
If you close your account
You can delete your account from inside the app at any time. Your name becomes “Former co-parent”, your login is purged, and your own private files are deleted.
What stays is the shared part — the messages between you, the expense list, the calendar. That history belongs to both of you, so closing one account does not empty the other parent’s calendar or wipe out what they are still owed.
We say this at sign-up and again at the moment you delete, so it is never a surprise. If both of you want the whole family removed, it is — after a 30-day grace period, then deleted completely, files included.
Reporting a vulnerability
If you believe you have found a security issue, please email privacy@gethalven.com with enough detail to reproduce it. We will acknowledge you within two business days. Please do not access, alter or keep any family’s information while investigating.
