Contacts
No numbers yet.
Upload your Excel list to start.
Reminders
Upload your list
Choose your Excel file (.xlsx, .xls or .csv). New numbers are added. Numbers you already have keep all their notes.
I guessed the columns. If the guess is wrong, pick the right one.
Backup and export
Private: everything is saved only in this browser, on this computer. Nothing is sent to any server.
If you clear your browser data, or use another computer, the notes are not there. So download a backup often (once a week is good).
Download backup
Saves one file with all numbers, notes and reminders.
Restore backup
Use this on a new computer. Pick a backup file you downloaded before. It replaces what is on this computer now.
Export to Excel
Makes a spreadsheet of your contacts and all notes.
