Private beta in progress

Every contact.
Every calendar.
In view.

SyncString reads contacts and calendars across iCloud, Google, and Microsoft 365, then writes confirmed contact changes to Google and Microsoft, individual iCloud contact changes within the Beta 1 boundary, and calendar changes to Google and Microsoft so native apps stay useful.

Made for life between ecosystems

Your information,
working together.

SyncString brings provider reads, contact indexing, itemized write previews, backup context, and run history into one clear workspace.

01

Provider sync

Keep native apps useful.

Read across iCloud, Google, and Microsoft, then preview confirmed contact writes to Google and Microsoft, plus individual iCloud contacts without photo or group-container writes.

02

Duplicate review

Review likely matches.

Index contacts by explicit opt-in, detect likely duplicates, and review comparison previews without executing a merge.

03

Deliberate changes

Know exactly what will change.

Create encrypted backups, review itemized changes, and delete only calendar events you explicitly select.

Control is a feature

Deliberate by design,
clear by default.

Each result keeps its provider identity. SyncString shows what was read, what may change, what was confirmed, and how each provider responded.

  • ✓ Provider reads across three ecosystems
  • ✓ Confirmed Google and Microsoft contact creates and updates
  • ✓ iCloud individual contact create and update; photos and group containers stay outside Beta 1 write scope
  • ✓ Explicit calendar-event deletion; never contact deletion
  • ✓ Contact indexing only after opt-in
  • ✓ Exact Google and Microsoft contact restore; no iCloud or calendar restore
  • ✓ No inferred deletion or duplicate merge execution
