Privacy Policy
Last updated: 2026-08-09
ipdet.app is a browser-based network toolbox. We built it so you can see what your network and browser reveal, which is why the default is to keep diagnostic data on your device. This page explains what happens to your data when you use the site.
How the tools work
Most of what the tools show you — your IP details, browser fingerprint, DNS, connectivity and speed-test results — is computed in your browser or looked up live and shown only to you. We do not keep these results on our servers, unless you explicitly create a shareable report link (see the next section).
To look up IP geolocation, the IP being queried is sent to third-party providers (such as ipinfo.io, ip-api.com and similar). Those lookups are governed by each provider's own privacy policy.
Earth Online
When you visit the site, we count one anonymous visit tick together with your country or region, derived from your IP address at our edge network. The IP itself is only used transiently, the full address is never stored.
If you choose to share a preset status, we record the status id, your country or region and the masked IP prefix for up to 48 hours, after which the data is deleted automatically. Statuses come from a fixed list — there is no free-text input.
Shared diagnostic reports
You can bundle your test results into a diagnostic report and share it. Creating a share link is always an explicit action — nothing is uploaded automatically. You choose which test sections to include and can mask the tails of IP addresses before the link is created.
When you create a link, the selected results are stored on our server infrastructure (Cloudflare Workers KV) so the people you share the link with can open it. The report is deleted automatically after the retention period you picked (1, 3 or 7 days). Links use unguessable random ids, we keep no directory of existing reports, and anyone who has the link can view the report until it expires.
Copying a report for an AI assistant or downloading it as JSON happens entirely in your browser and stores nothing on our servers.
Documentation assistant
The documentation assistant answers questions from our documentation site. It only starts when you use it: the assistant is loaded on demand, and the question you type is sent to GitBook, which hosts our documentation and provides the assistant, to generate an answer.
The assistant can also read the test results currently on your page — your IP addresses with their location and network, and the results of any tests you have run. This never happens silently: the assistant must ask, and you approve it with the confirmation button shown in the chat. Declining still lets it answer from the documentation.
The conversation runs between your browser and GitBook; it does not pass through our servers, and we do not store it. GitBook's own privacy terms apply to the messages you send.
What we collect through analytics
We use Google Analytics to understand how the site is used. Through it, the following is collected:
- An approximate location derived from your IP address (country / region / city). Google does not share your full IP address with us.
- Your browser language (for example en or zh).
- Standard analytics data: pages visited, device and browser type, the referring site, and a randomly generated visitor ID stored in a cookie.
What we collect when you sign in
Signing in is optional — you can use every tool on the site without an account. We use Google Firebase Authentication to manage your login and to sync your achievements. When you are signed in, the following is collected:
- Your sign-in email, used to identify your account so we can provide the features that require logging in.
- Your usage count of advanced features, used to calculate your achievements.
Error & performance telemetry
This deployment uses Sentry, an error-monitoring service, so we can find out when the site breaks and fix it. Telemetry is sent to Sentry through our own server relay and is not shared with anyone else. It includes:
- Technical error reports: what went wrong in the code, on which page, and your browser and operating system type.
- Performance timings, such as how fast pages load.
- When an error occurs, a replay of the moments leading up to it, so we can reproduce the problem.
- Your IP address, attached to error reports as they pass through our relay. Network-related problems often cannot be diagnosed without it, and it lets us estimate how many visitors an error affects. It is never shared and is deleted together with the rest of the telemetry.
- All telemetry data is deleted automatically after 30 days of retention.
Why we collect it
We use the analytics data to understand how the site is used and to improve the user experience. This data is not used to personally identify you, and we never sell it.
Your account data (email and advanced-feature usage count) is used only to identify your account, to provide the features that require signing in, and to calculate your achievements. We do not use it for advertising and never sell it.
Error and performance telemetry is used solely to find and fix defects. It is never used for advertising or to track you across sites, and it is deleted automatically after a short retention period.
Cookies & local storage
Google Analytics stores a cookie to recognise returning visitors.
Your own settings (theme, language, tool preferences) are kept in your browser's local storage and never leave your device.
If you are in the EU/EEA or UK
We currently do not show a cookie consent banner. If you would rather not be measured by analytics, you can opt out at any time using the methods below — blocking the analytics cookie does not affect any tool on the site.
To opt out: use a content blocker (such as uBlock Origin) or Google's official opt-out browser add-on, block third-party cookies, or clear this site's cookies. Self-hosted copies of ipdet.app only run analytics if their operator configures it.
Data retention
Analytics data is kept according to Google Analytics' retention settings (up to 14 months) and is then deleted automatically. Account data is kept while your account exists.
Browser checks on this site do not start BitTorrent swarm or magnet tests. See also Terms of Use and About.
