Frequently Asked Questions

▶Is patient data safe when using NumSwift?

Yes. NumSwift processes all text entirely in your browser. No data is uploaded to any server, and no phone numbers or patient information leave your device. This makes it suitable for use alongside HIPAA-aware workflows, though you should always follow your organization's data handling policies.

▶Can I extract numbers from scanned referral letters?

NumSwift works with text, not images. If you have a scanned letter, first run it through your OCR software (most EHR systems include this), then paste the resulting text into NumSwift. The phone numbers will be extracted from the OCR output.

▶Does it work with international patient numbers?

Yes. NumSwift recognizes phone number formats from over 200 countries using the libphonenumber library. This is especially useful for clinics in border areas or hospitals that serve international patients.

▶Can I use this alongside my EHR system?

NumSwift does not integrate directly with EHR systems, but the workflow is simple: copy patient contact text from your EHR screen, paste into NumSwift, and tap call or SMS. It works with Epic, Cerner, Athenahealth, and any system that displays phone numbers on screen.
