# PlatPhorm Contacts

PlatPhorm Contacts is a privacy-first, browser-local contact management and conversion workspace.

## Product capabilities

- Import user-selected device contacts where the Contact Picker API is supported.
- Import Android, Google, iOS, iCloud, Outlook, vCard, and CSV exports.
- View, add, edit, search, sort, filter, select, and delete contacts.
- Profile quality; repair names, phones, emails, dates, encodings, and broken vCards.
- Review contacts missing email, phone, postal address, or every contact method before optional deletion.
- Detect exact first-and-last, first-initial-and-last, fuzzy-name, phone, email, organization, and address duplicate signals.
- Review bounded duplicate clusters with confidence and field differences; low-confidence matches never merge automatically.
- Merge and prune fields with session undo and redo history.
- Export vCard 3.0, vCard 4.0, Google CSV, Outlook CSV, and normalized CSV.
- Review conversion loss before every export.
- Process up to 100,000 contacts using a Web Worker, incremental local indexing, virtualized rows, and cancellable jobs.

## Privacy boundary

Contact values remain in browser memory by default. IndexedDB persistence requires explicit consent. This server never receives imported contact values and publishes no analytics containing contact values.

An explicit connected operation can send one reviewed generated CSV, capped at 4 MiB, through the protected Data Studio publish endpoint to private PlatPhorm Files storage or a PlatPhorm Sheets workbook. The operation requires PLATPHORM_API_KEY, displays conversion loss before transfer, stores neither the key nor source file in Contacts, and returns the destination receipt.
