Privacy Policy
Last updated: March 28, 2026
The Short Version
SynapsesOS is local-first software. Your code, your data, your machine. We never see it, never store it, never transmit it. This privacy policy covers the synapsesos.com website and the install script — because the software itself doesn't talk to us.
What the Software Does
SynapsesOS runs entirely on your local machine. It:
- Stores all data locally in SQLite databases on your filesystem (
~/.synapses/) - Never sends your code, graph data, or personal information to any server
- Never checks licenses, never uploads usage telemetry
- Sends only minimal anonymous pings for install/active-user counts (see "Anonymous Pings" below)
- Has no user accounts, no authentication against our servers, no cloud dependency
If you enable the optional Brain feature, it communicates only with your local Ollama instance — never with our servers.
What the Website Collects
The synapsesos.com website uses Cloudflare for hosting and DDoS protection. Cloudflare may collect:
- Anonymous analytics — page views, country-level location, browser type. No individual tracking, no cookies for analytics.
- Server logs — IP addresses in standard web server logs, retained briefly for security purposes.
We do not use Google Analytics, Facebook Pixel, or any individual tracking tools. We do not set tracking cookies.
Cookies
This website uses only one cookie:
- Theme preference (
synapses-theme) — stored in localStorage, not a cookie. Remembers your light/dark mode choice. No data is sent to any server.
Cloudflare may set essential security cookies (e.g., __cf_bm) for bot protection. These are functional, not tracking.
Third-Party Services
- Cloudflare — hosting, CDN, DDoS protection. Cloudflare Privacy Policy
- GitHub — source code hosting, releases, issue tracking. GitHub Privacy Statement
- Google Fonts — font loading (Plus Jakarta Sans, JetBrains Mono). Google may log font requests. Google Privacy Policy
Anonymous Pings
SynapsesOS sends minimal anonymous pings to help us understand aggregate usage. These are:
- Install ping — sent once when you install via the install script. Contains only: OS (macOS/Linux), architecture (arm64/x86_64), and version.
- First launch ping — sent once when the desktop app is first opened. Contains only the event name.
- Weekly active ping — sent at most once per week from the desktop app. Contains only the event name.
These pings contain no personal data — no IP addresses are logged, no cookies are set, no device identifiers are sent. They exist solely so we can see aggregate counts (e.g., "42 installs this week, 30 weekly active users"). All pings are fire-and-forget — if they fail, the app continues normally.
Data We Do Not Collect
We do not collect, store, or process:
- Your source code or codebase content
- Your AI agent conversations or prompts
- Your Synapses configuration or graph data
- Personal information or email addresses
- Usage telemetry beyond the anonymous pings described above
Third-Party AI Services
SynapsesOS is a local tool that connects your codebase to AI agents you choose (e.g., Claude, GPT, Cursor, Copilot). SynapsesOS itself does not send your code or data to any external server. However, the AI agents and services you connect to may process, store, or transmit your code and prompts according to their own privacy policies. SynapsesOS has no control over and assumes no responsibility for the data practices of third-party AI services. We recommend reviewing the privacy policy of any AI service you use with SynapsesOS.
Children's Privacy
This website and software are not directed at children under 13. We do not knowingly collect data from children.
Your Rights
Since we don't collect personal data, there's nothing to access, correct, or delete.
Changes to This Policy
If this policy changes, we'll update this page with a new "Last updated" date. Since we don't collect email addresses, we can't notify you directly — check back if you're concerned.
