Privacy Policy

Last updated: August 8, 2026

Short version: Synapse collects nothing. No accounts, no tracking, no telemetry, no cloud.

This document is a plain-language summary provided for convenience and is not legal advice.

What we collect

Nothing. Synapse has no accounts, no sign-in, no analytics, no telemetry, and no crash reporting. The App sends no usage data, identifiers, or personal information to its creator or to any third party.

Where your data is stored

Everything you create (collections, selectors, variables, credentials, and configuration) is saved as plain files on your own device, in a directory you choose. Your data never leaves your machine unless you put those files somewhere else, for example in your own Git repository or backup.

Network activity

The only network traffic Synapse generates is the HTTP requests you explicitly send to the API endpoints you configure. The App contacts no servers of its own. Requests go directly from your machine to the endpoints you target, and their responses are handled locally.

Third-party endpoints

When you send a request to a third-party endpoint, you interact directly with that provider's service, under its own privacy policy. Synapse has no involvement in, visibility into, or responsibility for how those services handle your data.

Credentials and secrets

Any API keys, tokens, or secrets you enter are saved only in your local files. Treat those files like source code: keep them secure and avoid committing secrets to shared repositories.

This website

Everything above describes the Synapse desktop app. This section covers synapse-app.org itself.

No cookies, no tracking

This site sets no cookies and uses no local storage, no analytics, no tag manager, and no advertising or tracking pixels. Nothing is stored on or read from your device, which is also why you are never asked to dismiss a cookie banner.

No third-party requests

Every asset (stylesheets, fonts, images, and scripts) is served from this domain. Your browser contacts no other host when loading these pages, so no third party receives your IP address or learns that you visited.

Server logs

Like virtually every web server, our host records standard access logs when a page or file is requested. These entries can include your IP address, the time of the request, the page or file requested, the referring page, and your browser's user-agent string. We use them only to operate and secure the site (diagnosing errors, measuring load, and identifying abuse), never to profile or identify you. The legal basis is our legitimate interest in running a secure, functioning website (Art. 6(1)(f) GDPR). Logs are kept only as long as needed for those purposes and are not shared with third parties except as required by law.

Downloads

Download links and installation scripts are served from this domain, so downloading Synapse involves no third-party service.

Your rights

Where the limited data described above constitutes personal data, the GDPR gives you the right to request access to it, its correction or erasure, restriction of processing, and to object to processing. You may also lodge a complaint with your national data protection authority. To exercise any of these, contact us at the address below. Note that access logs generally cannot be linked to an individual without additional information you would need to provide.

Changes to this policy

If this policy changes, the "Last updated" date above will be revised. Because the App collects no data, changes will typically only clarify existing practices.
