Privacy Policy

Last updated: 2026-07-20

The short version: nothing you type into the converter leaves your browser. All conversion happens locally in JavaScript. We use Google AdSense (which can set advertising cookies) and Cloudflare Web Analytics (which is cookieless and collects no personal data).

1. Operator

This site ("NENGO", "we", "our") is a small, independently operated reference site.

2. What we do not collect

Years and dates you enter into the converter are processed entirely within your browser. We do not log them, transmit them to a server, or share them with anyone. There is no account system and no sign-in.

3. What is collected automatically

Hosting access logs (IP address, browser, referring URL, timestamp) — standard infrastructure logs kept by our hosting provider (Cloudflare) for security and abuse prevention.
Google AdSense data — ad impressions, clicks, and cookie-based personalization data, processed by Google LLC in the United States.
Cloudflare Web Analytics — aggregate, cookieless page-view statistics with no personal identifiers.

4. Cookies & local storage

Google AdSense cookies — used to serve and measure ads. Managed by Google LLC. You can control ad personalization at Google Ads Settings.
Consent flag (era-cookie-consent) — a localStorage entry that remembers you dismissed the cookie notice. It contains no personal data.

Disabling cookies in your browser will not affect the converter itself; ads may simply become less relevant.

5. Third parties

We do not sell, rent, or share personal data. Data flowing to Google LLC (US) via AdSense is governed by Google's Privacy Policy. Cloudflare processes only infrastructure-level and anonymous aggregate data.

6. Your rights (GDPR / UK GDPR / CCPA)

If you are in the European Economic Area, the United Kingdom, or California, you have rights to access, correct, delete, or object to processing of personal data. Because this site does not store what you type, those rights in practice concern only hosting logs and any data held by Google or Cloudflare, which you can also exercise directly with those providers via the links above.

7. Children's privacy

This site is a general-audience reference tool. We do not knowingly collect personal information from children under 13.

8. Changes

We may revise this policy as laws or the site change. The "Last updated" date above always reflects the latest revision.
