Privacy Policy

Last updated: May 13, 2026. LastBrowser is designed with privacy in mind. This policy explains what data is collected, how it's used, and your rights.

LastBrowser is open-source software (MIT license). You can verify all privacy-related code in the source repository.

TL;DR

LastBrowser is a local-first application. Your browsing data, tabs, workspaces, and settings are stored locally on your machine. No data is sent to external servers unless you explicitly configure an AI model provider API key.

1. Data We Collect

We collect no data by default. LastBrowser runs entirely on your machine. The only data that exists is what you create:

  • Local storage: Tabs, workspaces, settings, kanban boards, agents, and sessions are stored in a local SQLite database at %APPDATA%/LastBrowser/ on Windows. Nothing is uploaded anywhere.
  • Cookies: Website cookies are stored in Electron session partitions on your local disk, exactly like a normal browser. You can clear them at any time via Settings → Privacy.
  • Cache: Website cache files are stored locally and can be cleared per app or globally.

2. AI Agent Data

The AI agent system is optional and opt-in. If you configure an AI agent:

  • Prompts and responses are sent to the AI model provider you configured (e.g., OpenAI, Anthropic, DeepSeek, OpenRouter).
  • We do not proxy, log, or store your prompts on any intermediary server.
  • Your API key is stored locally in the app's settings database and never transmitted to anyone except the provider you selected.
  • Each provider has its own privacy policy governing how they handle your data.

3. Telemetry

LastBrowser has an optional telemetry feature that is disabled by default. If enabled, it collects:

  • App version and operating system
  • Feature usage statistics (anonymous, no personal identifiers)

You can enable or disable telemetry at any time via Settings → Privacy.

4. Third-Party Services

The LastBrowser website uses the following third-party services:

  • GitHub API — The download page fetches the latest release version from api.github.com/repos/Loggableim/lastbrowser. No personal data is sent.
  • Google Fonts — Font files are loaded from Google Fonts CDN. See Google's Privacy Policy for details. We plan to self-host fonts in a future update.

5. Updates

LastBrowser checks for updates via GitHub Releases (api.github.com) on startup. This sends: app version, OS, Electron version. No personal identifiers.

6. Your Rights

  • Right to know: This document explains what data exists and where.
  • Right to delete: All local data can be deleted via Settings → Privacy → Clear All Data, or by uninstalling the application.
  • Right to portability: Workspace data can be exported as JSON via the workspace manager.
  • Right to opt out: Telemetry is off by default. AI agent usage is opt-in.

7. Contact

For privacy-related questions, open an issue on GitHub or contact the maintainer via the Imprint.
