Synchronize company contacts two-way into native iOS & Android phone dialers. Segmented with granular tag permissions, approval workflows, and strict multi-tenant isolation.
No proprietary dialer apps or vendor lock-in. Real two-way synchronization directly into native iOS & Android operating systems.
Syncs seamlessly over CardDAV to Apple iOS Contacts and Android (DAVx5). Callers are instantly identified by name in your native phone dialer and WhatsApp.
Control exactly who can View, Add, Edit, Delete, or Share contacts on a per-tag basis. Bulk permission matrix controls allow instant policy updates across the whole team.
Prevent rogue changes and accidental deletions. All contact creates, edits, and deletions made by members enter an approval queue for Tenant Admin review with side-by-side visual diffs.
Restrict what physical devices sync. A field agent can have their phone restricted strictly to "Field Clients" so sensitive VIP phone numbers never download to mobile hardware.
Enforced by PostgreSQL Row-Level Security (RLS) under non-owner database connections. Built-in DPDP consent basis logging, granular audit trails, and trash retention.
Import CSVs and vCards with automated header mapping and duplicate detection. Works offline via a resilient Service Worker PWA with conflict resolution.
ContactsNX strictly separates roles at the database layer. Platform Admins manage system infrastructure and tenants only — with zero access to tenant contacts. Tenant Admins govern their company directory and approvals, while Members only touch contacts granted via fine-grained tag permissions.
Every plan includes native CardDAV two-way sync, tag-based access control, and full PWA offline support.
For small teams and testing sync.
For growing teams requiring approvals & tag filtering.
For organizations needing high scale and priority support.
