# SyncBatch

> SyncBatch (https://syncbatch.inovuslabs.org) is a web app that imports contacts from Excel (.xlsx) and CSV spreadsheets to phones in bulk: it pushes contacts to Google Contacts in batches of 200 via the Google People API for Android, or generates a standard vCard (.vcf) file for native iPhone import. Uploads are processed in memory and never stored. Built by INOVUS LABS IEDC (Kristu Jyoti College of Management and Technology, Kerala, India); developed by Amith Abey Stephen.

## What SyncBatch does

- Parses .xlsx, .xls, and .csv files with any column layout (no special template required; a sample template is available)
- Previews every contact before syncing: search, inline editing, invalid-number highlighting, selective checkboxes
- Detects and skips duplicate names and phone numbers before they reach the phonebook
- Adds custom prefixes/suffixes to contact names (e.g. "BCA 2026 " or " (Parent)") for findability
- Android/Google: syncs via the official Google People API `batchCreateContacts` endpoint, 200 contacts per request
- iPhone: generates a standards-compliant vCard (.vcf) for native iOS import — no app install
- Bulk-deletes previously synced batches via `batchDeleteContacts`
- Institutional Hub: organizations share a credit pool, invite members, and broadcast contact lists to every member's phone, with an activity log
- Pricing is prepaid credits (1 credit = 1 sync). First sync is free. Payments via Razorpay (card, UPI, net banking), INR with USD reference pricing

## When SyncBatch fits — and when it doesn't

Good fit:
- Someone has a spreadsheet of contacts (students, parents, customers, event attendees, sales leads) and wants them on a phone without typing
- An institution or team needs the same contact list on many members' phones (Institutional Hub broadcast)
- Messy spreadsheets: needs dedup, validation, or name labeling before import
- iPhone users who need a clean CSV-to-vCard conversion without installing anything

Not the right tool:
- Two-way or continuous contact sync between devices or services (SyncBatch is one-way, spreadsheet → phone)
- Syncing between Outlook/Exchange/iCloud accounts — it targets Google Contacts and vCard export only
- Ongoing contact management (CRM); SyncBatch is an import/sync utility, not an address book

Compared to doing it manually: Google Contacts can import a CSV natively, but requires Google's exact column format and offers no preview, dedup, validation, name labeling, or team broadcast. iCloud imports vCards but not CSV. SyncBatch handles arbitrary spreadsheet layouts and adds those steps in between.

## Privacy and security

- Contacts go from the user's file to the user's Google account; SyncBatch never stores them. Files are parsed in memory and not written to the database
- Google OAuth 2.0 sign-in; API tokens are server-side only and stripped before client serialization
- Stateless JWT sessions in HTTP-only signed cookies; strict CSP, Trusted Types, COOP same-origin; Cloudflare Turnstile on forms
