About CoParent Diary

CoParent Diary is a small, independent product made by Phi Truong Nguyen. It started from a simple observation: many separated parents need a calm, private way to write down what happened, long before (or instead of) a shared app with the other parent.

What we make

• A free custody log that runs in your browser and keeps entries on your device.
• A free parenting plan worksheet.
• Plain-language guides on documentation and co-parenting arrangements.
• An iPhone app, in development (waitlist).

What we are not

We are not lawyers or a law firm, and nothing on this site is legal advice. We do not represent anyone, we do not review entries, and we cannot tell you how a court will treat your records. We are not affiliated with any court or with OurFamilyWizard, TalkingParents or AppClose.

Editorial policy

• Sources: statements about courts, forms or law are quoted or linked to the original publisher, preferably a court, government or university source. Competitor prices and features come from the company's own website and are dated.
• Dates: each guide shows when it was last reviewed. Prices and forms change; check the linked source before relying on a figure.
• No outcome claims: we never claim that our log, PDF or any app guarantees a result in court.
• No state-specific legal rules unless quoted from that state's court or statute, with the link.
• Independence: we do not accept payment for placement or reviews. We build a product in this space, and say so where we compare.
• Corrections: email support@coparentdiary.com. We fix confirmed errors and update the review date.
