Overview

Synrows is a desktop application for generating database test data. Your database credentials, project files, and generation rules stay on your device unless you explicitly use cloud AI features.

Data stored locally

• Project metadata, schema graphs, and generation rules in a local SQLite database
• Database connection secrets in your operating system keychain
• Optional BYOK API keys (OpenAI/Anthropic) in the keychain — never sent to Synrows servers
• Downloaded local LLM model files in app data

Synrows Cloud (optional)

When connected, the desktop app registers a device with our Cloudflare Worker at api.synrows.app and receives an API key stored in your keychain. Cloud AI requests (schema analysis, rule refinement, SQL/report design) send only the prompts and schema summaries required for the task — not your full database contents.

You can revoke cloud registration anytime in Settings. Device identifiers and usage quotas are stored in Cloudflare D1 for authentication and rate limiting.

Local LLM mode

When using local models, inference runs entirely on your machine. Model weights are downloaded from Hugging Face; no inference data is sent to Synrows Cloud.

Website & downloads

The marketing site at synrows.app is static. Download links resolve to signed installers hosted on Cloudflare R2 at updates.synrows.app. We do not use third-party analytics on the landing page.

Auto-updates

Packaged builds check updates.synrows.app for signed updates. No personal data is transmitted during update checks — only the current app version and platform.
