Liability for links

This website links to pages run by others, such as The Things Network, ThingSpeak or OpenStreetMap. I have no influence on their content; their operators alone are responsible for it. If I become aware of any legal violation, I will remove such links immediately.

Project notes

LOGisch – navigation disclaimer

LOGisch is a tool for keeping records on board. It does not replace an official nautical chart, an official marine weather report or a dedicated AIS receiver. The weather alerts in the app are not official warnings. The skipper remains responsible for the vessel.

BienenWaagenManager – free firmware and build guide

Firmware and build guide are provided free of charge. Building, installing and operating the device is at your own responsibility. I am liable for damage only in cases of intent and gross negligence. The operator of the device is responsible for compliance with radio regulations (including transmit power and duty cycle in the 868 MHz band).

RudelLink is not a product of FRITZ! GmbH and has no affiliation with it. The app is provided free of charge; I am liable for damage only in cases of intent and gross negligence. The setting to accept a device’s untrusted certificates weakens the protection of the connection and is meant only for your own devices in your home network.

Parzello – maps and planning aids

Aerial photos, maps and parcel boundaries come from open data of the German surveying authorities (© LGL Baden-Württemberg, dl-de/by-2-0; © Geobasis NRW, dl-de/zero-2.0; © Bavarian Surveying Administration, CC BY 4.0; © BKG TopPlusOpen, dl-de/by-2-0). They are for orientation only and do not replace official documents. Suggestions on crop rotation and companion planting are general rules of thumb without any guarantee of growing success.

RudelPlan – calendars and sync

RudelPlan displays events from the calendars on the device and syncs the pack calendar via the users’ OneDrive. I give no guarantee for the availability of OneDrive or for events that are not or incorrectly shown due to wrong input or missing sync. OneDrive is a trademark of Microsoft Corporation; RudelPlan has no affiliation with Microsoft.

RudelKey – responsibility for master password and emergency kit

RudelKey stores passwords so that only the master password or the recovery key can open them. If both are lost, the data cannot technically be recovered – not even by me. The emergency kit should be kept safe and backups made regularly. Liability for data loss caused by lost credentials is excluded as far as legally permissible.

TonStrom – playback on your own network

TonStrom passes the phone’s sound to devices on your own home network. Users are responsible for the content they play; the terms of use of the respective services and copyright law must be observed, especially for public performance. Device names and manufacturer trademarks belong to their owners; TonStrom is not affiliated with any speaker manufacturer.

RudelSafe – responsibility for master password and emergency kit

RudelSafe stores documents so that only the master password or the recovery key can open them. If both are lost, the documents cannot technically be recovered – not even by me. RudelSafe does not replace original documents. Liability for data loss caused by lost credentials is excluded as far as legally permissible.

RudelOrga – content of the group

Whatever is in a RudelOrga group is entered by its members themselves, and they are responsible for it. Settlements of the group kitty are a calculation aid without guarantee. If a group’s key is lost, the encrypted data in the folder cannot be recovered – not even by me.

RudelCash – not yet a till under the KassenSichV

RudelCash is in development and is not yet connected to a certified technical security device (TSE). It may therefore not be used as an electronic recording system for real takings in Germany. The club or organiser using the app is responsible for complying with tax and till regulations (Cash Register Security Regulation, registration with the tax office, retention). Card payments are governed by the club’s contract with its payment service provider.

RudelRally – measurements without guarantee

RudelRally measures distance and time with the phone’s GPS, an OBD-II adapter or a wheel sensor. Values may deviate depending on reception, device, vehicle and surroundings and are not a calibrated measuring instrument. The orienteering solver’s results are based on OpenStreetMap data and the rules entered; they may be incomplete or wrong and do not replace your own check. The backtrack warning is an aid, not a guarantee. I give no guarantee for scoring results or for the app being permitted under the rules of an event; on public roads the traffic regulations apply, and the app should be operated by the co-driver.
