Privacy in SyncX
How SyncX stores library data, media, platform sessions, opt-in desktop usage statistics and limited website analytics during the public beta.
Desktop library data
SyncX stores collected records, task settings and activity history in a SQLite database on your device. SyncX does not provide a hosted cloud library or upload your collection to a SyncX account.
Platform sessions
SyncX uses dedicated local Chromium browser profiles, each kept with the browser that created it, and a native credential database. Existing browser import is explicit and domain-scoped. Credentials never enter the renderer, library exports, Cloudflare or diagnostic logs.
Downloaded media
Images and videos are written to a folder on this Mac, or to a NAS folder you mounted in Finder, according to each account’s settings. The library database stays on this Mac. Remote covers may use the system WebView’s HTTP cache. Removing these files is under your control.
Text and speech recognition
Text in images and speech in videos are recognized on your device, with a bundled model and the speech recognizer built into macOS. Images and audio are never sent anywhere. Images and audio that aren’t saved are fetched from the platform only for this, read and deleted right away. Bilibili subtitles come from Bilibili, and YouTube captions come from YouTube in the video’s original language. You can turn either off in Settings › Library.
AI agents
The optional syncx command reads the library read-only. What an agent does with what it reads — including sending it to an AI provider — is governed by that agent and its provider, not SyncX. The command never opens your platform logins.
Exports and diagnostics
JSON and CSV exports are created only when you request them. SyncX redacts Cookies, tokens and page-signing values from logs and exports; review any exported content before sharing it.
Desktop usage statistics
Off until you agree. SyncX asks once; you can change it any time in Settings › Privacy. When on, the app sends anonymous events: launches, each day it is used, how long it stays open, which features are used (connecting an account, collecting, exporting, searching), collection counts, durations and error categories, plus app version, operating system and a random install ID. It never sends account names, collected content, search terms, file paths or error messages. Events go through SyncX’s Cloudflare Worker to Google Analytics, which receives only your country, not your IP address. Data is kept for 14 months. Turning statistics off deletes unsent events and the install ID.
Website analytics
The website uses Google Analytics after the page becomes interactive. It records page path, language and when the install command is copied. Do not send account names, library searches or desktop collection content. Google may process technical data such as browser, device and approximate location under its own terms.
Removal
Removing a connection clears its associated local session through the app. Uninstalling the application alone may leave its data directory; remove that directory separately if you want to erase the local library and media.
