A five-minute habit that saves a real headache later
Losing contacts usually isn't dramatic -- a sync error, a wrong tap, an app switch gone wrong -- but it's very hard to undo without a backup. Exporting takes a few minutes and gives you a plain file you control.
CSV vs vCard, and when it matters
CSV is the more universal choice for spreadsheets or importing into most services, while vCard (.vcf) tends to preserve more contact detail and works well for moving contacts directly between phones.
Frequently Asked Questions
Can I use the exported file in other services?
Yes, CSV and vCard are standard formats that most email services and contacts apps can import.
How often should I back up my contacts?
There's no fixed rule, but it's worth doing right after you've added or reorganized a lot of contacts.
