Privacy policy

This website collects no personal data of its own. It sets no cookies, embeds no tracking pixels, measures no traffic and loads no fonts or scripts from third-party servers. No access log is kept either.

Controller

No access logs

The web server behind this site keeps no access log. Neither IP addresses nor requested pages, timestamps or browser identifiers are stored.

Delivery via Cloudflare

The site is delivered through the network of Cloudflare, Inc. (101 Townsend St., San Francisco, CA 94107, USA). In doing so, Cloudflare processes your IP address in order to route the request and fend off attacks. To tell humans and automated traffic apart, Cloudflare may set a strictly necessary cookie (__cf_bm) that expires after a short time and serves no analytics purpose. The legal basis is our legitimate interest in secure operation under Art. 6(1)(f) GDPR; the transfer to the USA is based on the European Commission's standard contractual clauses.

Getting in touch and support

If you email us — through the support page, a bug report or a beta tester application — the details you send are stored in order to deal with your enquiry. The legal basis is Art. 6(1)(b) or (f) GDPR. We do not pass this data on and delete it once the matter is settled, provided no statutory retention period applies.

Taking part in beta tests

Anyone applying as a tester voluntarily provides details such as their device model and, if they wish, a phone number for the tester group. Communication in that group runs over WhatsApp (WhatsApp Ireland Ltd.), whose privacy policy applies to it. Participation is voluntary and can be withdrawn at any time; on request we will remove you from the group and delete your details.

Linked services

The App Store links lead to Apple Inc., which is responsible for the data processing there. The Barcode Generator and the MatLuk apps each have their own privacy notices.
