Privacy

Data on your device

The app stores connectivity history, notes, settings and diagnostic logs locally on your Windows device. This information is not automatically uploaded to us.

You can delete outage history and notes from the app. Reports you export are stored wherever you choose. Resetting or uninstalling the app removes its package-local data but does not remove exported files stored elsewhere.

Connectivity checks

The app makes small requests to a DYHI service hosted by Cloudflare and to connectivity endpoints operated by Microsoft and Google. The website checker contacts Cloudflare, Mozilla and Google.

These services and your network providers can receive ordinary technical information such as your IP address and request time. DYHI does not send your outage history, notes or diagnostic logs with these requests.

Website and Store

Cloudflare hosts and protects the website, receiving your IP address, requested page and browser details. Cloudflare Web Analytics measures visits and page performance without analytics cookies or browser storage. Unsampled data is held seven days, then aggregated; reports cover six months. Free-plan security request analytics cover seven days; other hosting records follow service, security and legal retention needs. See Cloudflare's analytics retention details.

Displaying Microsoft's Store badge contacts Microsoft before you click. It receives your IP address, browser details and website source to display the badge and report aggregate Store referrals. See the Microsoft Privacy Statement.

The website saves site files in your browser so the checker opens during an outage. This functional storage has no fixed expiry; updates replace it, the browser may remove it, or you can clear it through browser site-data controls.

Contact and service providers

If you contact us at support@dyhi.online, we use the information you send to respond to and handle your request. Support correspondence is kept only as long as reasonably needed for that purpose or applicable legal obligations.

Hosting and email providers process information necessary for their services, including in the European Economic Area, UK and US. UK transfers rely on EU adequacy; Cloudflare and Microsoft use the EU–US Data Privacy Framework for certified US transfers or standard contractual clauses where applicable. Ask us for safeguard details; see Cloudflare's transfer terms and Microsoft's statement above.

Our legal basis is our legitimate interest in operating and securing the app and website, understanding website use and supporting users.

Your rights

For personal data we hold, such as support correspondence, you may request access, correction, deletion or restriction, or object to processing where applicable. Contact support@dyhi.online to exercise these rights. We cannot access data stored only on your device.

You may also complain to the Belgian Data Protection Authority or your local data protection authority.
