Questions

Something else? Email us and we'll answer before you buy.

Where is my data stored? Is it private?

Everything is saved inside your browser on this device. Nothing is uploaded and there is no account, so no company holds a copy of your wedding records. They are not encrypted, though: anyone who can use this device and browser can open them, so keep the device locked. Download a backup regularly (Settings → Data & backup → Back up now) and keep it somewhere as safe as the records themselves.

Does it work without internet?

Yes. Open index.html and it runs fully offline. You can also host the folder on any website and choose “Install app” in Chrome or Edge to get a desktop or phone icon that works offline.

Can I use it on my phone or iPad?

Yes. The layout adapts to phones and tablets with a bottom navigation bar. Each device keeps its own data, so use Back up / Restore to move records between devices.

How do I start fresh after trying the sample data?

Go to Settings → Data & backup → Erase records. Every sample record is removed, and so are the sample couple’s names, wedding date and budget, so nothing of theirs ends up on your printouts. Your other settings are kept.

Is this for wedding planners with several clients?

No. It is for one couple planning one wedding. There are no clients, no invoices and no pipeline of events in it. If you plan weddings for other people as a business, our event planning system is built for that.

How do payment reminders work if the app is offline?

The app cannot send notifications, so it hands the dates to your own calendar instead. “Calendar reminders” on the dashboard (or “Download calendar reminders” on Payments due) saves a calendar file with every unpaid payment and every open task that has a date. Open it on your phone or computer and each one lands in your calendar with an alert a few days before. Download a fresh file whenever the dates change. Overdue payments are also shown in red on the dashboard and counted in the menu.

What happens to the checklist if our date changes?

Change the date under Settings → Your wedding and every task moves with it, because each one is stored as “so many days before or after the wedding”, not as a fixed date. A task you have pinned to a fixed date stays where it is.

How many guests can it hold?

It is built for several hundred. The guest list pages through 10, 25, 50 or 100 rows at a time, and the seating plan stays quick with 300 guests at 30 tables.

How are plus-ones, children and babies counted?

A plus-one belongs to the guest who was invited with them, with their own name and meal, and takes a seat at the same table. Children are guests in their own right with their own meal. A guest marked as a baby takes no seat and no meal, and is counted separately on the meal numbers so the caterer can plan a high chair.

Can both of us use it?

Each device keeps its own copy of the records, so there is no live sync between two phones. Most couples keep it on one laptop and print what the other needs, or move the records between devices with Back up now and Restore.
