Privacy Policy

Last updated: 10 June 2026

POJ Composer is built to respect your privacy. There are no accounts, and we do not collect or store personal information on any server. The Service does display ads through Google AdSense — see “Advertising” below for how that works.

Preferences stored on your device

Your choices — the Pe̍h-ōe-jī name variant and the er/ir spelling style — are saved only in your browser’s local storage, on your own device. They never leave your browser and are not sent to us. Clearing your browser’s site data removes them.

Approximate location

When the page loads, the app reads the rough region your IP address maps to (provided by our host, Vercel) for a single purpose: to pick a sensible default spelling for first-time visitors. This is used in the moment and is not stored, logged or linked to you. Your choice always overrides it.

Advertising

The Service displays ads through Google AdSense to keep it free. Google and its partners use cookies to serve ads based on your prior visits to this and other websites, and these ads may be personalised. The text you type and the romanisation it produces are never sent to Google or used for advertising.

You can opt out of personalised advertising in Google Ads Settings. To learn how Google uses information from sites that use its services, see Google’s advertising policy.

What we don’t do

Apart from the ad serving described above, the Service uses no analytics of its own and no other third-party trackers. We do not sell or share your data.

Changes

This policy may be updated from time to time. Any changes will appear on this page with a new “last updated” date.
