Privacy

There are no accounts. Calls go encrypted directly between the two devices and are never recorded or stored. No tracking, no advertising. We count page views and how calls end, as plain daily numbers that point to no person.

Who is responsible

mixed.world GmbH, impressum@mixed.world. The postal address and who represents the company are in the imprint.

What we keep, and for how long

A code: its id, name, picture, description and settings, until the code is deleted. Name, picture and description are visible to whoever holds the link.

A phone: a random id, technical details of the device and the app (such as model, system, language, app version), when the terms were accepted, whether the app is a genuine store copy, and the ids it can be rung through. Until the phone is removed. A recovery key is kept only in a form that cannot be reversed.

A call: only while it lasts. What is recorded is that it happened, for which code and how it ended — not who called, never what was said.

Messages: spoken and written messages, the replies to them, and the name or reason a caller chose to give, for 30 days at most or until you delete them. They are not end-to-end encrypted on our server and can be read by whoever holds the code or the message's link.

A call rating: tied to no person; the words for 90 days, the number for 400, both at once with the code.

Calendar, if you switch it on: only start and end times for the next two weeks, never titles, people or places; deleted when you switch it off.

Place, if you switch it on: only here or away per code and phone. Where the place is, we never learn: it stays on your phone. Deleted when you switch it off.

A purchase: the store's transaction id, what was bought and until when, so it can be restored without an account. Payment details stay with the store.

An abuse report: a reference to the message, the code and the reason, for 180 days.

A shop order: what the invoice needs — name, email, address, company, VAT id — for as long as the invoice and its legal retention require. The app asks for none of it.

Backups: nightly copies, kept 14 and 30 days. Something deleted can remain in them until then.

Cookies and browser storage

One cookie, klingel_lang, only if you pick a language on a code's page, for one year. The pages also remember in your browser what you chose — language, the name you typed, microphone, camera and speaker, drafts in the card designer. None of it is sent anywhere or used to recognise you; it is needed for the service you asked for (§ 25(2) TDDDG).

Who receives data

Apple's and Google's push services, so your phone rings: the call's id, the code's name, the caller's optional name; for a written message also its text, so it can show while the phone sleeps.

Apple and Google, to check that the app is genuine and a purchase is valid.

Map services (Apple Maps, OpenStreetMap), if you set a place on the map: they see your phone's address and the map area, not the place you choose.

Our servers are in Germany.

Legal bases

Providing the service (Art. 6(1)(b) GDPR), running it safely (Art. 6(1)(f) GDPR), and legal retention for orders (Art. 6(1)(c) GDPR). Calendar, location and notifications only with your permission on the phone, which you can withdraw there at any time.

Your rights

Access, rectification, erasure, restriction, portability, objection, and a complaint to a supervisory authority. Deleting a code or a phone in the app deletes its data. For anything else: impressum@mixed.world.
