Private by default. Clear by design.

Your chats, projects, settings, and history are stored in a local database (SQLite) on your own device. Synara runs a small server process locally on your machine to power the app — it is not a hosted cloud service, and your data never leaves your computer just by using Synara.

When you chat with a model, Synara connects directly to the provider you chose — Claude, Codex, OpenCode, Cursor, Antigravity, Grok, Droid, and so on — using your own existing logins. Your prompts and code go only to that provider, governed by their privacy terms. Synara does not proxy, copy, or store that traffic on any server of ours.

There's nothing to sign up for and no Synara login. Want to open Synara from your phone or another laptop? That's self-hosted: you expose your machine over your own network (LAN or Tailscale), protected by an auth token you generate and control. Nothing routes through us.

Synara can send anonymous, aggregate usage analytics (via PostHog) to help us understand which features matter and where things break. This is off by default — it never runs unless you explicitly opt in.

Analytics events carry no "person profile" and aren't tied to your identity. You can keep them disabled (the default) or, if you'd like to help, turn them on by setting SYNARA_TELEMETRY_ENABLED=true. An in-app Settings → Privacy toggle is on the way.

The in-app Feedback Synara dialog sends only when you press Submit. It includes the text you wrote, app version, operating system, provider and model, runtime modes, and session/turn status so we can understand the conditions around a problem.

Automated diagnostics do not include chat messages, prompts, project paths, repository contents, session logs, or screenshots. Reports are delivered through our website and email provider to the Synara maintainer for support and product improvement, rather than being added to an analytics profile.

The optional sponsorship service collects your company name, contact email, logo, destination and promotional brief to review and deliver your paid placement. This service is separate from using the desktop app.

Stripe collects billing address, country, tax details when supplied, payment terms consent, and processes your recurring payments; we do not receive your full card details. Supabase stores sponsorship records and private submitted images. When configured and enabled, Resend delivers operational emails. An optional private Discord channel receives review and operational notifications containing the company, destination, contact email, request message and the request identifier. Approved logos, company names, descriptions and destinations appear publicly on Synara and, for Platinum sponsors, on the personal sponsors page.

We process these records to handle your request and contract, prevent abuse and maintain payment records. Private records are accessible only to authorized operators. A private materials link lets its holder view and submit materials for one campaign, without billing data; it expires after seven days, extended through the 23-hour payment window if initial materials are submitted near expiry, and can be revoked. Keep it confidential. We retain transaction records for applicable accounting and dispute requirements; contact us to request access, correction or deletion of other sponsorship data. Providers may process data internationally under their published data protection terms. No sponsorship data is sold.

Contact the seller listed in the sponsorship terms for privacy requests.
