A custody journal app, not a notebook
Plenty of parents start their custody record in a paper journal or their phone's notes app. It is a good instinct: write things down as they happen. The problem is what those tools leave out, structure, real timestamps, and any sign the entry was not rewritten later. Oya Shield is a purpose-built custody journal app that keeps the good instinct and closes the gaps.
Where a notebook or notes app falls short
A paper journal or a notes app is free, familiar, and always to hand, and for low-stakes jottings that is plenty. What they were never built to do is stand up later: prove when an entry was written, show it was not quietly edited, keep photos and receipts with the event they belong to, and turn months of notes into one clean record. That gap is exactly what a custody journal app is for.
| Oya Shield | Paper / notes appA notebook or your phone's notes | |
|---|---|---|
| Structure | Guided fields: title, facts, category, severity, photos. | A blank page. You decide the format every time, and consistency slips. |
| Timestamps | Automatic. Each entry records when the event happened and when it was logged. | Manual. A date you type yourself, easy to forget or approximate. |
| Edits preserve the original | Yes. Amendments keep the original on record, with a fingerprint against tampering. | No. A notes app can be edited silently; nothing shows the original wording. |
| Photos & receipts in context | Attached to the entry they belong to. | Scattered across your camera roll and files, hard to place later. |
| Shared expense tracking | Built in. Splits by percentage or amount, receipts attached. | A separate spreadsheet, or nothing at all. |
| Court-ready export | Yes. One clean, dated PDF of your whole record, amendments noted. | Retyping, screenshots, and loose paper. |
| Backup & privacy | Encrypted and tied to your account; survives a lost or broken phone. | A notebook can be lost; notes may sync to accounts without real protection. |
| Cost | One subscription, 7-day free trial. | Free, but the gaps can cost you when it counts. |

When a notebook or notes app is enough
Honestly: if conflict is low, you just want to jot the occasional reminder, and you never expect any of it to matter in court, a notebook or your notes app is perfectly fine. Not every family needs a structured record. Oya Shield is for the situations where the record might have to hold up: where when it was written, whether it was changed, and what evidence sits with it are the things that decide whether anyone believes it.
Frequently asked questions
Is a notes app good enough to document custody issues?
For casual reminders, yes. The risk is that a notes app can be edited silently, so an entry cannot show it was written at the time and never changed. When a record might be questioned later, that gap matters. A purpose-built custody journal keeps the original on record whenever you amend an entry.
Why not just keep a paper journal?
A paper journal is a fine start, but it cannot timestamp itself, it cannot hold photos or receipts with the entry, and it can be lost or damaged. Oya Shield keeps the same day-by-day habit while adding automatic timestamps, attached evidence, a tamper-evident edit history, and a clean PDF export.
Can I move my existing notes into Oya Shield?
You can re-enter past events as dated incidents so your record is in one place going forward. New entries then carry automatic timestamps and a history that preserves the original whenever you make a correction.
What makes a custody journal hold up better?
Records taken at the time, kept in a consistent factual format, with evidence attached and a history that shows they were not rewritten, carry the most weight. Those are exactly the things a blank page cannot prove and a purpose-built app is designed to.
