Hi Product Hunt! I built Oya Shield after watching people close to me go through contentious custody situations. The pattern was always the same: by the time details mattered, they lived scattered across notes apps, camera rolls, and memory. Oya Shield is a private custody log. You document incidents and shared expenses in one place, every entry timestamped, photos attached. The part I'm most proud of is the amendment history: when you edit an entry, the original stays on record with both timestamps visible. Your record can show it was never quietly rewritten, which is exactly what a mediator or judge will wonder about. It's not a communication platform, and it doesn't need your co-parent to join anything. It's just your record, private to you, exportable as a clean PDF when you need it. iPhone only for now, 7 days free. I'd genuinely love feedback, especially from anyone who has been through this.
