Data sources and licences
SPOLLOW uses data, software and symbols from various providers. The following explains their sources and applicable rights. Free licences grant you independent rights in the specified components; the SPOLLOW terms do not restrict these rights.
Version 1.0 · Published · Effective from
1. Fixtures: OpenLigaDB
SPOLLOW contains information from OpenLigaDB (https://www.openligadb.de/), available under the Open Database License 1.0 — ODbL (https://opendatacommons.org/licenses/odbl/1-0/).
The app selects needed fixtures, standardises their structure and processes them without results, media or club logos. Coverage includes the supported German national leagues and available relevant domestic and European cup fixtures for selected clubs. Display depends on actual data availability.
The stored adapted sports dataset can be exported free as a machine-readable file in the OpenLigaDB section of the app's “Data sources and licences”. No Lifetime purchase is needed. The export includes source, licence and modification notices. The adapted sports data derivative is licensed under ODbL 1.0; its attribution and sharing conditions apply to relevant reuse.
Personal settings, purchase data, calendar links, reminders and separately processed weather/additional stadium data are outside this export. The database licence grants no rights to third-party trademarks, club logos or images.
2. Additional venues: Wikidata
Additional structured stadium information is based on Wikidata (https://www.wikidata.org/) under CC0 1.0 (https://creativecommons.org/publicdomain/zero/1.0/), following its licensing information (https://www.wikidata.org/wiki/Wikidata:Licensing) for structured data.
It is bundled as a local app catalogue. The app makes no online Wikidata request for this. A venue stated by the sports data provider takes priority. An additional assignment expressly labelled “home stadium” does not confirm that a particular match actually takes place there.
Club websites may help verify a stadium assignment. This does not make their texts, photos or logos CC0 content or part of this permission.
3. Weather: Deutscher Wetterdienst
Data source: Deutscher Wetterdienst (DWD), MOSMIXL (https://opendata.dwd.de/weather/localforecasts/mos/MOSMIXL/). According to DWD's legal information (https://www.dwd.de/DE/service/rechtlichehinweise/rechtlichehinweisenode.html), the freely accessible geodata used is subject to Creative Commons Attribution 4.0 International — CC BY 4.0 (https://creativecommons.org/licenses/by/4.0/).
SPOLLOW selects, assigns and displays the data itself and converts temperatures from Kelvin to degrees Celsius, adapting the data for the app. Forecasts concern the assigned forecast point, not a measurement at the stadium.
Displayed precipitation probability concerns more than 0.1 mm in the hour preceding the forecast time. It is not a precipitation amount or certainty about weather.
Naming DWD does not imply that DWD has checked, endorsed or certified SPOLLOW.
4. TV and streaming information
SPOLLOW derives information from locally stored editorial rules concerning regular first- and second-Bundesliga matches in Germany for the 2025/26 to 2028/29 seasons. A principal source is the DFL media-rights announcement of 5 December 2024 (https://www.bundesliga.com/de/bundesliga/news/dfl-medienrechte-vergabe-tv-partner-clubs-saison-25-26-28-29-29352).
Exceptions, short-notice changes and unlisted competitions may differ. This is not a complete programme guide. Check actual availability with the provider. Other rights and offerings may apply outside Germany.
SPOLLOW broadcasts no matches, uses no broadcaster logos for this and grants no access to paid services. Factual naming of a broadcaster or platform creates no partnership and transfers no broadcasting rights.
5. Software and functional symbols
SPOLLOW uses, among others, AndroidX, Kotlin, Google Play Billing, Google Play In-App Review and RevenueCat. Functional symbols derive from Lucide and partly its Feather foundation.
Each component has its own terms, such as Apache License 2.0, MIT, BSD or ISC. Google Play Billing and other Google components also have applicable Android SDK or Play Core terms. Multiple applicable terms and individual third-party notices must also be respected.
The app-version-specific catalogue of components, versions, copyrights and licence notices is accessible in the app's “Data sources and licences”. The additional website edition is at SPOLLOW open-source notices (https://needbuilt.de/en/apps/spollow/recht/open-source/).
6. Names, trademarks and other content
Club, league, data provider, broadcaster and platform names provide factual identification. Naming them does not imply they operate, support or certify SPOLLOW.
The provider chose the name SPOLLOW. The SPOLLOW logo and AI arena templates created for this project were generated using generative AI and own design instructions. They are separate from the Lucide/Feather symbol set. This implies neither exclusive copyright protection nor permission to use third-party distinctive signs.
Free data and software licences grant no blanket rights to SPOLLOW as a whole or to third-party trademarks, logos or images. Each component's rights follow its own source and licence.
