Privacy Policy

Effective 8 October 2026. Applies to the HEIC Converter app for Windows published by HAYAH.

The short version

HEIC Converter processes your photos on your own PC. It never uploads your photos or anything about them, has no account and no advertising. From version 1.1.1 it sends anonymous usage events (which buttons were used and what happened, never your photos), which you can turn off in Settings.

Your photos

The app reads only the files and folders you open, drop onto it, or select in File Explorer. Converted copies are written to the location you choose. Photo contents and their metadata (such as date taken, camera model and GPS location) never leave your device. When you convert, the app copies that metadata into the new file, so keep that in mind before sharing a converted photo.

Settings

Your preferences (output format, quality, output folder, language) are stored locally in the app's own settings on your PC. Uninstalling the app removes them.

Network use

The app connects to Microsoft Store services, to check whether you own Pro and to process a purchase you start. From version 1.1.1 it also sends the anonymous usage events described below to hayah-heic.pages.dev, unless you turn them off.

Usage events

From version 1.1.1 the app sends anonymous usage events: which screens and buttons were used and what happened. For example: that a batch was converted, how many files and to which format, that a photo could not be converted and the general reason, that the Unlock Pro page was shown and closed, or that a purchase was cancelled or completed. Each event carries the app version, whether you use the free version or Pro, the country as reported by our network provider (Cloudflare), a random identifier for that app session and a one-way hash of a random identifier created when the app was installed. That identifier is not linked to your Microsoft account or your purchases.

Events never contain your photos or anything that could identify them: no images, file names, folder names, paths, EXIF data, dates taken, camera details or locations. Our server refuses any event that could carry text. We use the events only to improve the app, keep them for up to 180 days, and do not sell or share them. You can turn them off at any time in Settings → Privacy → "Share usage data"; the app then sends nothing and discards anything not yet sent.

Purchases

Purchases are made through the Microsoft Store with your Microsoft account. HAYAH never sees your payment details. Microsoft's handling of that data is described in the Microsoft Privacy Statement.

Diagnostics

Apart from the usage events above, the app sends no diagnostics of its own. Windows may send crash reports to Microsoft according to your Windows diagnostic settings, and Microsoft may share aggregated reports with HAYAH through Partner Center. These contain no photo content.

Children

The app does not ask anyone, including children, for personal information. The usage events above are anonymous and are the same for every user.

Changes and contact

If this policy changes, the new version will appear on this page with a new effective date. Questions: support@hayah.dev.
