1. About this page
These are usage notes for KiekR, not the terms of a contract. There is no clickwrap, no account, no sign-up; nothing on this page is meant to bind you beyond what statutory law already does. We publish it so you know what KiekR is, how we run it, and what we expect of users. The legally mandated imprint is at kiekr.app/impressum and the privacy policy at kiekr.app/privacy.
2. What KiekR is
KiekR is an iOS and Android application that pairs over Bluetooth with a user-owned MeshCore-compatible LoRa radio, together with the public coverage map at map.kiekr.app and the contribution API at api.kiekr.app. The service is free of charge, has no user accounts, and is operated by Marcel Verdult, an individual developer based in Nordenham, Germany. On iOS, your relationship with Apple is governed by Apple's Licensed Application End User License Agreement, which you accept when you install through the App Store — that is a relationship between you and Apple, not between you and us.
3. What we expect of users
When you use KiekR, you are responsible for complying with the law that applies to operating a LoRa radio in your jurisdiction — in particular rules on frequency use, transmit power, and duty cycle. Please do not use the app or the network to transmit unlawful content, to harass others on the mesh, or to interfere with the operation of the MeshCore network. Statutory prohibitions apply regardless of what this page says; we restate them here only to set honest expectations.
4. No warranty; donor liability standard
KiekR is offered free of charge. Under § 521 BGB (German Civil Code, gift law) a donor is liable to the recipient only for intent and gross negligence. Mandatory protections — in particular liability for harm to life, body, or health under any degree of negligence — remain in place at the statutory floor and we make no attempt to reach below them. The MeshCore mesh is a decentralised, participant-operated network; we have no role in its availability or in the conduct of its other participants and accept no responsibility for either.
5. Map curation and contributions
map.kiekr.app is a curated public map. We may decline, correct, or remove entries — and stop accepting uploads from a contribution public key — where there are concrete grounds: fabricated data, impersonation of another operator, repeated 🚫 stop-sign violations on the same repeater key, or a third-party complaint backed by prima facie evidence. Where there is a feasible way to reach the affected contributor (typically by emailing the admin of the repeater key in question) we notify them. The data-protection side of the public revocation list is covered in our privacy policy.
6. Updates to this page
These usage notes may be revised. The current version is always at kiekr.app/terms; the effective date above moves when there is a material change. We do not treat continued use as acceptance of a contract — there is no contract here. If a change is one you don't like, you are free to stop using the service at any time.
7. Applicable law
KiekR is operated from Germany under German law. For users habitually resident in another EU Member State, the mandatory consumer-protection rules of that state remain applicable (Art. 6 (2) Rome I Regulation, EC No 593/2008). Jurisdiction for any dispute follows the statutory rules — for EU consumers, in particular Articles 17 to 19 of the Brussels I-bis Regulation (EU) No 1215/2012, under which a consumer can sue at their domicile and can only be sued there.
