How does sync.blue® connect Relution with Android contacts using CardDAV, LDAP, or CSV, and what credentials or prerequisites are required for setup?

sync.blue® connects Relution with Android contacts by serving as a central CardDAV, LDAP, or CSV source that Relution can deploy to managed devices: CardDAV—create a sync in the sync.blue® dashboard that writes to the sync.blue® CardDAV server, then provision a CardDAV account in Relution with server carddav.sync.blue and path /API_KEY/addressbook; credentials: username API_KEY and password API_KEY; LDAP—create a sync to the sync.blue® LDAP Server and deploy LDAP settings with host ldap.sync.blue, port 389, Bind DN uid=API_TOKEN,ou=users,dc=sync,dc=blue, Base DN ou=API_TOKEN,ou=contacts,dc=sync,dc=blue, and password API_TOKEN; CSV—sync to the sync.blue® Address Book and expose a CSV feed from the sync.blue® Directory using the personal API key for the endpoint; prerequisites: an active sync.blue® account, at least one connection targeting CardDAV/LDAP/CSV, the generated API key or token, and a CardDAV/LDAP profile or the sync.blue® Android app distributed via MDM for device-side contact availability.

What scheduling options are available in sync.blue® for Relution-to-Android synchronization (real-time vs scheduled), and what sync frequency or latency is typical?

sync.blue® supports scheduled Relution‑to‑Android contact sync: the connection (Relution ↔ CardDAV/LDAP) can run manually or on hourly, daily, weekly, or monthly intervals, and the sync.blue® Android app polls on a device interval set via MDM (minimum 15 minutes; 1440 minutes/daily recommended); in practice, updates reach Android within the chosen interval—about 15 minutes at the minimum setting or up to 24 hours on the recommended daily schedule—with incremental changes applied each run and an optional full resync available on demand.

What security and privacy measures does sync.blue® apply when syncing Relution contacts to Android, including encryption, data residency, and access controls?

When syncing Relution contacts to Android, sync.blue® operates exclusively in Germany-based data centers (Hetzner and NETWAYS; ISO 27001) under GDPR with a Data Processing Agreement and documented TOMs available; by default, contacts are not stored on the platform unless explicitly configured to host an address book (e.g., via CardDAV, LDAP, or CSV); IT can manage access via MDM by auto‑provisioning the sync.blue® Android app (e.g., with Microsoft Intune) and locking the host, CardDAV user, password, and sync interval; details on encryption and granular access-control mechanisms are provided in the official sync.blue® security documentation.

How does sync.blue® support scalable Android–Relution deployments, including unlimited connections, multiple devices or tenants, and delivery of a unified company phone directory to managed devices?

sync.blue® scales Android–Relution rollouts by syncing contacts from any source to a central CardDAV/LDAP (or CSV import) address book and distributing the sync.blue® Android app with managed credentials via Managed Google Play/Android Enterprise; admins can create unlimited connections, target multiple devices or tenants with separate assignments and policies, choose one‑way or two‑way scheduled or real‑time sync, and deliver a unified company phone directory that stays automatically updated on every managed device.

Can the Relution–Android contact sync in sync.blue® be configured as one-way or two-way, and how are conflicts and updates to existing contacts handled?

Yes—Relution–Android contact sync in sync.blue® can be set per connection to one-way or two-way; existing contacts are recognized (by email or by first and last name) and updated instead of duplicated, and if fields differ the source in the active direction overwrites the target on the next incremental run; a full re-sync can be triggered when needed.
