ScheduleMyWedding
ScheduleMyWedding works entirely on your own device. It does not connect to any ScheduleMyWedding server (none exists), and nothing you type is ever uploaded or sent to anyone.
Your wedding-day plan, including the timeline, contacts, phone numbers, locations and notes, is saved locally in your browser on your device, and nowhere else. Only you can see it. If you clear your browser data or use the Start fresh button, it is gone; export a backup file first if you would like a copy to keep.
Like any web page, the app loads its fonts from the internet, but these requests never include your wedding details.
Printing happens on your own device through your browser's normal print dialog. A printed or PDF run sheet contains whatever you typed, including names, phone numbers, times and locations, so share each sheet only with the people who need it on the day.
Export project creates a JSON file on your device containing your full plan, including contact details for your vendors. Treat that file as private and share it only with people you trust.
