Private custody log for iPhoneOne parent
Stop carrying the whole story
in your head.
Start the record now, before you need it, not after. Log what happened in two minutes: dates, details, a photo when you have one. Most weeks, nothing comes of it. The day something does, you'll have it: timestamped, with the edits you make on your iPhone kept in its history. No invitation, no shared account, nothing to set up together.
Your record. Every entry in one private place, with its importance, its category and the children it's about.
Timeline. Entries and expenses together in date order, so the whole story reads in sequence.
Expenses. Shared costs with receipts and splits, and what each of you owes, kept apart.
The PDF. Pick what goes in, review every entry, and get a dated PDF for your files, a mediator or a lawyer.
Why Oya Shield is different
Most co-parenting apps need your co-parent to agree. This one doesn't.
A record is only useful if it already exists on the day you need it, which means it has to survive on its own, without anyone else's cooperation. Shared platforms don't work that way: they only produce a record if the other parent signs up, often pays for their own plan and keeps using it. Sometimes that works. Often it doesn't, because they won't, because they forget, or simply because proposing a shared app is a conversation you'd rather not start yet.
Oya Shield needs one parent. Yours. It records what actually happens in your life, not only what happens inside an app you both agreed to use, whether you're co-parenting amicably and just want your own clear account, or things are harder than that.
What makes a record credible
The details people look for are already there.
Mediators and lawyers ask the same questions: when was it written down, has it changed, and how do you know? Every entry answers them.
times on every entry
When it happened, and when you wrote it down.
Edits don't overwrite
The original stays in the entry's history on the iPhone where you changed it.
- I saw or heard this myself
- The child or another person told me
- This is my inference or opinion
How you know this
Note whether you saw it yourself, were told, or are giving your own view.
invitations to the other parent
Nothing for them to install, join or agree to.

The app, its PDF reports and this website.
Read on your iPhone
Screenshots, receipts and dictation are processed on the device. Nothing is uploaded for the analysis.
The Shield
Edits don't overwrite.
The original stays.
Any record invites one question: how do we know this wasn't changed later? Oya Shield answers it by design: on the iPhone where you make a change, the original stays in the entry's history, and the record journal notes every entry added, changed or removed.
Edits go into the history
Change a detail on your iPhone and the original stays in the entry's history, showing exactly what changed and when.
A journal on your iPhone
Every entry you create, change or remove on this iPhone adds a linked line to its record journal, and Reports shows whether the journal still checks out. It uses this iPhone's clock and stays on this iPhone.
Photos keep their own clock
Attach a photo days later and the PDF still prints the time the camera recorded, with location details stripped out.
Exports show their work
The PDF flags amended entries, so what you hand to a mediator or adviser is transparent about its own history.
Assisted drafts keep their origin
The assistant's original wording stays on record, and exports label what you rewrote.
Two ledgers, one record
Everything that happens, in its place
The custody log
A fair account, captured in two minutes
Every entry gets a title, description, category, importance and the date it happened, plus photos when you have them. Filter by importance, or see entries and expenses together on one timeline, and tell at a glance what's genuinely recurring and what was one bad week.
- Dictate it: the audio never leaves your iPhone
- Log from Siri or a Lock Screen control
- Tag the children involved
- Note how you know: you saw it, were told, or inferred it
The expense ledger
Shared costs, without the back-and-forth
Log each expense as it happens and split it by percentage or exact amount. Attach the receipt, pick a category, and the ledger keeps the running account, so nothing has to be reconstructed from screenshots six months later.
- Split by percentage or fixed amounts
- Categories for school, medical, activities and more
- Attach receipt photos to any entry
- What you're owed and what you owe, kept apart, plus settled and this-month totals
- Each expense keeps its own currency
The PDF
Asked for a timeline? It's already written.
Choose a period, a child and what goes in, then review every entry before it's included. The report lays out a summary, a combined timeline and each entry with its record history.
- When it happened, and when it was written down
- Each entry's record history, edits included
- Expenses: who paid and what's still owed
- A fingerprint on each export, so two copies can be compared

Import & Bulk Add
For the weeks you never got around to writing up.
Pick the screenshots you already have, or paste the conversation. Oya Shield drafts the entries and you decide what's kept.
Entries and expenses, together
Up to 8 screenshots of a thread, or 20 receipts, in one pass.
Review before saving
Every proposal stays a draft until you confirm or discard it.
Analyzed on your iPhone
The reading and drafting happen on the device, not on a server.
Needs an iPhone with Apple Intelligence; without it, import still extracts the text for you.
And the rest
Small things that make it easy to keep going.
Recurring expenses
Set up school fees or lessons once. Each one waits as a draft for you to confirm, and is never added on its own.
Say it instead
Dictate an entry: your speech becomes text on your iPhone and the audio isn't kept. If you like, rewrite it in a calm, factual tone, and your own words stay on record.
Siri, widgets and the Lock Screen
Ask Siri to log an entry or an expense, or start one from a widget or a Lock Screen control.
Face ID lock
Keep the app behind Face ID or your passcode.
Tag each child
Tag entries and expenses with the children they're about, and make a PDF for one child.
iPhone and iPad
Your record syncs to your account, so it's on both and comes back on a new phone.
Share with a professional
Your lawyer sees what you choose, for as long as you choose.
When it's time to bring in a lawyer or mediator, give them a read-only view of your record instead of a folder of screenshots.
You choose what it covers
Entries, expenses or both, a date range, categories, children, and anything you'd rather leave out. A plain summary shows what they'll see, including new entries that match, until you end access.
Read-only, in their browser
They sign in free with the address you invite. Nothing to install, and nothing they can change or add.
Their visits are listed
When they open your record, it shows up in the share's activity (repeat visits within half an hour count once), and so does each PDF they save with the portal's Print or save PDF button.
End access anytime
The share stays live until you end it. End it, and they can no longer open your record.

A private Schedule tab is in testing. Choose your parenting pattern once, and Oya Shield shows who has the children today and when the next handover is.
The month at a glance
Start from a pattern like alternate weekends or week on, week off. Each day shows who has the children, with handovers marked.
Planned nights with each parent
See the nights your schedule plans with each parent, this month and this year.
Swaps and holidays
Add a swap, a holiday or make-up time, and note who asked and how it was agreed.
Only you can see it
It stays in your own account. Nothing is sent to the other parent, and they have nothing to join.
Still in testing, so details may change before it reaches the App Store.

Private by design
Your log is yours alone.
Documenting a difficult relationship takes trust. Oya Shield is built so you never have to wonder who can see what you wrote. Your co-parent is never told it exists.
Private to your account
Your records are sent over encrypted connections and stored with access controls, private to your account. There is no co-parent view, because there is no co-parent account. Nothing is shared unless you share it.
Passwordless
Sign in with a one-time email code. No password to remember, or to leak. Lock the app with Face ID.
Yours to take
Export your full record anytime, free, with or without a subscription: every entry and every attachment, in one ZIP file. Your documentation belongs to you.
Start free. Keep everything.
Free to download, and eligible new subscribers get the first week free through the App Store. After that, one simple subscription, not two: $8.99 a month or $85.99 a year. Every feature included: no tiers, no locked exports, and nothing extra to buy for a second person. Oya Shield runs on iPhone and iPad only.
Most months, you'll open it, log a few minutes, and move on. That's the point. It's low-cost precisely because most of the time you won't need it, and it's already there, unbroken, the one time you do. Cancel anytime in the App Store.
iOS 26 or later. Prices are in US dollars, and the App Store shows yours in your local currency. Renews automatically unless cancelled at least 24 hours before the trial or the current period ends.
FAQ
Fair questions
The things people ask before trusting an app with something this personal.
Does my co-parent need to use Oya Shield too?
No. There's no invitation, no shared account and nothing for them to agree to. They are never notified that you use it, and they can't see what you log unless you decide to show them. One parent, one subscription.
Can my co-parent see what I log?
No. Your records are private to your account: they're sent over encrypted connections and stored with access controls, and there is no co-parent view. Nothing is shared unless you share it yourself: a PDF you export, or a read-only view for a lawyer or mediator that you can end at any time.
What happens when I edit or delete an entry?
An edit doesn't overwrite the entry: on the iPhone where you make it, the original stays in the entry's history, with what changed and when, and your PDF reports can include that history. The history stays on that iPhone, so it doesn't come back on a new phone or after a reinstall, and Export Full Record is how you keep a copy. Deleting is different: it removes the entry and its attachments for good, so to correct something, edit it rather than delete it.
Can I use my records in court?
You can export your full log as a clean, dated PDF to share with a mediator or attorney, with amended entries clearly noted. Whether documentation is admissible is up to the court and varies by jurisdiction, and your attorney can advise on your situation. Oya Shield is a documentation tool, not legal advice.
Can I share my record with my lawyer or mediator?
Yes. In Settings, tap Share with a professional and choose what it covers: entries, expenses or both, a date range, categories, children, and anything to leave out. They sign in free with the address you invite and can read your record but not change it. Their visits are listed in the share's activity, and you can end access at any time.
Is my data private and secure?
Records are sent over encrypted connections and stored with access controls that limit them to your account. Sign-in is a one-time email code, so there's no password to leak, and you can lock the app behind Face ID.
What does it cost?
Oya Shield is free to download, and Premium costs $8.99 a month or $85.99 a year in US dollars. Creating entries, PDF reports and sharing with a professional need Premium: one subscription with every feature included and no second plan to pay for. The App Store shows the price in your local currency. Eligible new subscribers get the first week free through the App Store, and it renews unless cancelled at least 24 hours before the week ends. Without Premium you can still open, edit and export your full record.
What if I get a new phone?
Sign in with your email on the new iPhone and your entries, photos, documents and shares come back. Edit histories, assistant labels and the record journal currently stay on the original phone, so before you switch, use Export Full Record there: it's free, and the file includes all three.
Can I log something without typing?
Yes. Tap the microphone on a new entry and say what happened. Your speech becomes text on your iPhone, and the audio is deleted straight after, never uploaded. You can also ask Siri to log an entry or an expense, or use the Lock Screen control.
Does AI write my custody record?
No, you do. The assistant can draft an entry from a screenshot or a pasted conversation, but nothing is saved until you confirm it, and the original wording stays on record and is labeled in your exports.
Do my messages leave my phone when the assistant reads them?
No. The reading and drafting happen on your iPhone, not on a server. Once you confirm a draft, that entry and any screenshots attached to it sync to your private account over an encrypted connection, like every other entry.
Does Oya Shield have a custody calendar?
Not yet. A private Schedule tab is in testing: it will show who has the children today, the next handover and the planned nights with each parent. Only you will see it, so it isn't a shared calendar, and there's no messaging with your co-parent.
Start your record tonight.
Hopefully you'll never need it.
Two minutes for the first entry. After that it's off your mind and on the record: organized, protected, and ready if the day ever comes.
