Privacy Policy
Last updated 14 July 2026
Template notice for the site owner: this page is a starting draft, not legal advice. Have counsel review it against your actual data flows before launch, and delete this box.
ZenSurf is built so that there is as little to write here as possible. The browser does not send us your browsing history, your searches, your bookmarks, or an identifier that links your installation to you.
What the app collects
- Nothing by default. There is no analytics SDK and no telemetry service in the shipped build.
- Update checks. The browser asks our update server whether a newer version exists. That request includes your version number, Windows build and CPU architecture, and unavoidably your IP address. We do not store IP addresses in logs beyond 24 hours, and update checks can be disabled in Settings → Updates.
- Crash reports. Opt-in only. If you enable them, a report contains a stack trace and build metadata — never URLs, page content, form data or cookies.
Sync
If you turn on sync, your bookmarks, settings and open Surf Stacks are encrypted on your device with a key derived from your passphrase. Our sync server stores ciphertext, a random device identifier and a timestamp. We cannot read your data, and we cannot recover it if you lose your passphrase. You may point sync at a server you run instead.
What this website collects
- Standard web server logs (IP address, user agent, requested path), retained 30 days for abuse prevention.
- No cookies are set for advertising or cross-site tracking. A single
localStorageentry remembers your light/dark preference and never leaves your browser. - Fonts are self-hosted. No third-party CDN sees your request for this page.
Third parties
Downloads and source code are hosted on GitHub, which applies its own privacy policy to requests you make there. Anything you type into a search box in ZenSurf goes to the search engine you selected — we are not in the middle of that request.
Your rights
Because we hold almost nothing tied to you, most access or deletion requests resolve to "there was no record". You can still contact us and we will tell you exactly what, if anything, exists.
Changes
Material changes to this policy will be announced in the release notes and on this page, with the date above updated.
