Privacy Policy
Effective 2 September 2026
NumLM Tools (tools.numlm.com) is built so that your data stays with you: every tool runs inside your browser, and there are no accounts, no analytics scripts and no advertising. This policy explains the little that our server does see and the choices you have. It covers tools.numlm.com only — the main site numlm.com has its own policy. This policy is published in English and Korean; if the versions ever differ, the English text governs.
Who we are
This site is operated by NumLM (너멜엠), the operator of numlm.com. For anything in this policy, contact us at numstats.kr@gmail.com.
What we collect — and what we don’t
We do not collect what you type into the tools. Inputs, pasted text and files are processed by JavaScript on your device and are never uploaded. The only personal data we process is:
- Server access logs. Like every web server, ours records the page path, date and time, IP address, browser type (User-Agent) and referring page of each request. The query string — the part of a URL where tool inputs can appear — is deliberately not logged. We use these logs to compile aggregate visit statistics (IP addresses are anonymised in the reports) and to protect the service against abuse. Legal basis under the GDPR: legitimate interest (Art. 6(1)(f)).
- Feedback. If you use the “Send feedback” button, the message you write — and your email address, only if you choose to add it — is sent to our own server and stored so we can read and answer it. Legal basis: consent (Art. 6(1)(a)); you can withdraw it at any time by asking us to delete your message.
- Nothing else. No account data, no tracking cookies, no analytics or advertising identifiers. We never sell personal data and never share it with third parties for marketing.
Data stored in your browser
Your preferences (language, theme, units, text size, favourites, recently used tools) and the inputs or records some tools keep (for example the subscription tracker) are stored in your browser’s localStorage so the site works and remembers your settings. This data never reaches our server. You can remove it at any time with a tool’s Clear button or by clearing the site’s data in your browser.
Third-party requests
Loading the site triggers a small number of requests to third parties. Each request necessarily transmits your IP address to that provider:
- Google Fonts (fonts.googleapis.com / fonts.gstatic.com) — serves the Noto Sans KR web font. Google’s privacy policy: policies.google.com/privacy.
- Frankfurter (api.frankfurter.dev) — the daily exchange-rate table (European Central Bank reference rates), fetched only when you open the Currency Converter.
How long we keep data
- Access logs are rotated and kept only as long as needed for the statistics and security purposes above, then deleted.
- Feedback is kept while we need it to respond and improve the service, and deleted when you ask us to or when it is no longer needed.
Your rights
Depending on where you live (for example under the GDPR, the UK GDPR, the CCPA or Korea’s Personal Information Protection Act), you may have the right to access, correct, delete or receive a copy of your personal data, to restrict or object to its processing, and to lodge a complaint with a supervisory authority. To exercise any of these rights, email us at numstats.kr@gmail.com. Note that access logs do not allow us to identify you by name; where we cannot identify you, some rights may not be technically applicable (GDPR Art. 11).
Children
The site is a general-audience service with no accounts. We do not knowingly collect personal data from children; the feedback form is not directed at them.
International use
The site is available worldwide. The limited data described above is processed on servers we operate, and feedback is handled where we are established (the Republic of Korea). By using the site or sending feedback from another country, you understand that your data is processed there under this policy.
Changes to this policy
If we change what we collect or how we use it, we will update this page and its effective date. Material changes will be flagged here before they take effect.
