Privacy Policy

TL;DR: Uptimes collects zero data. We have no servers, no analytics, no tracking, and no accounts. Everything stays in your browser. This privacy policy exists because the Chrome Web Store requires one.

1. Overview

Uptimes is a browser extension that monitors the availability and response times of web endpoints. It is designed with a zero-knowledge architecture — meaning we, the developers, have no way to access, view, or collect any data related to your usage of the extension.

There is no backend server. There is no user account system. There is no telemetry, analytics, crash reporting, or usage tracking of any kind.

2. Data We Collect

None.

We do not collect:

• URLs you monitor
• Response times or uptime statistics
• Your IP address
• Browser fingerprints or device identifiers
• Personal information of any kind
• Usage patterns or click/interaction data
• Error reports or crash logs

This is not a policy decision — it is an architectural guarantee. There is no server for data to be sent to. The extension's source code is open source and can be audited to verify this claim.

3. Data Stored Locally

Uptimes stores the following data locally in your browser using chrome.storage.local:

• The list of URLs you have added as monitors
• Response time measurements for each ping
• Up/down status history
• Calculated statistics (uptime percentage, average response time)
• Your extension preferences and settings

This data never leaves your device. It is stored exclusively in your browser's local storage and is subject to your browser's own data management policies. You can delete all stored data at any time by removing the extension or clearing its storage through your browser settings.

4. Third-Party Services

Uptimes does not integrate with, send data to, or receive data from any third-party services. This includes:

• No Google Analytics or similar analytics platforms
• No Sentry, Bugsnag, or similar error tracking
• No Firebase, Supabase, or similar backend services
• No advertising networks
• No CDN-hosted assets (everything is bundled in the extension)

5. Network Requests

The only network requests made by Uptimes are the HTTP pings to the URLs you explicitly add as monitors. These requests:

• Are made directly from your browser to the target URL
• Use mode: 'no-cors' and do not read response bodies
• Contain no authentication tokens, cookies, or custom headers
• Do not pass through any proxy, relay, or intermediary server

The extension never phones home. It never contacts our domain. It never makes any network request that you did not explicitly configure.

6. Extension Permissions

Uptimes requests the following Chrome extension permissions:

• storage — To save your monitor list and ping history locally
• alarms — To schedule periodic ping checks
• host_permissions — To make HTTP requests to the URLs you configure

No permission is used for data collection, tracking, or any purpose other than the core monitoring functionality.

7. Children's Privacy

Uptimes does not collect any personal information from anyone, including children under 13. Since no data is collected at all, COPPA and similar regulations are inherently satisfied.

8. Changes to This Policy

If we ever change this privacy policy, we will update the "Last updated" date at the top of this page. Given that our architecture fundamentally prevents data collection, changes are unlikely to be material. However, should the extension ever introduce features that involve network communication with our own servers (such as optional encrypted sync), this policy will be updated before any such feature is released.
