Information we collect
We collect a deliberately small amount of information to operate the site:
- Server logs. Our hosting provider (Cloudflare) records standard server logs including IP address, browser type, referring pages, and timestamps. These logs are retained according to Cloudflare's retention policy and are used for security, abuse prevention, and operational diagnostics.
- Speed test measurements. If you run the speed test, the test connects directly to a Measurement Lab (M-Lab) server using the open NDT7 protocol. M-Lab receives your IP address, throughput measurements, and timing data as part of the test. Their open data policy is documented at measurementlab.net/privacy. HanoiLUG does not see or store individual speed test results.
- Voluntarily submitted information. If you contact us by email, we receive your email address and the contents of your message.
What we don't do
To set expectations clearly:
- No advertising. HanoiLUG does not display advertising. No ad networks, no AdSense, no retargeting pixels.
- No third-party analytics. We do not currently run Google Analytics, Plausible, Mixpanel, or any equivalent service. If this changes, we will update this policy and disclose the specific tool in use.
- No accounts. There is no signup, no login, no user profile. We do not collect names, passwords, or payment details because we never ask for them.
- No selling or sharing of data. We do not sell or share visitor information with third parties for marketing.
Cookies
HanoiLUG uses minimal cookies. The only cookie set by the site itself stores your theme preference (light or dark mode) on your device. This cookie is not transmitted to us and contains no identifying information.
You can disable cookies through your browser settings. Disabling them may reset your theme preference on each visit but will not otherwise affect functionality.
Third-party services
The site contains links to third-party websites including router manufacturer support pages, ISP portals, and reference resources. These third-party sites have their own privacy policies. We are not responsible for their content, privacy practices, or data handling.
The speed test connects to Measurement Lab servers, an independent research consortium. Cloudflare provides hosting and CDN services and processes server logs accordingly.
Data sharing
We do not sell, trade, or rent your personal information to third parties. We may share aggregated, non-identifying data in public reports about site usage. We may disclose information when required by law, subpoena, or to protect our rights and the safety of users.
