Notice PowerSync Service

Our Plan for Phasing Out Sync Rules

We're phasing out Sync Rules in favor of Sync Streams over the next 15 months. From 15 March 2027, new PowerSync Cloud instances can only use Sync Streams. From 15 December 2027, you can no longer deploy Sync Rules and support for them ends.

React Native SDK

React Native Client SDK: v2.3.0

[ADDED] `disconnectAndClear({ soft: true })` clears your synced tables but keeps the internal sync state. A later `connect()` for the same user then completes without downloading all data again.
