What this is

GrooveGrid is an unofficial, fan-made timetable app for Boomtown. It is not produced, endorsed by, or affiliated with Boomtown Festival UK Ltd or the organisers of Boomtown Fair. Festival names, lineups, and artist names belong to their respective owners and are used here only to identify what's playing when.

Accuracy

Set times are transcribed by hand from a community-run clashfinder and cross-checked against the official Boomtown lineup where possible, but mistakes happen — that's what hand-transcription does. Nothing shown in this app is guaranteed accurate. Always check times and stage locations against the official Boomtown app or the boards on site before making plans around them. GrooveGrid accepts no liability for any loss, missed set, or inconvenience arising from relying on information shown here.

No warranty

This app and its data are provided "as is", with no warranty of any kind, express or implied, including as to accuracy, completeness, or fitness for a particular purpose.

Data source

Set times come from the community clashfinder at clashfinder.com/m/boomtown26, maintained by MiniMurderdoll, used under a CC BY-NC 3.0 licence, cross-checked and filled in against the official lineup at boomtownfair.co.uk. Artist notes are written only where an act could be verified, drawing on the official Boomtown lineup, Last.fm, and MusicBrainz.

Privacy

Sets you save are stored in your browser's local storage and never leave your phone — there is no account, and nothing about your saved sets is ever sent to GrooveGrid or anyone else.

To get a basic sense of whether anyone's using the app, and whether it's actually fast on a festival phone signal, we use Cloudflare Web Analytics. It doesn't use cookies, local storage, or a persistent ID to follow you between visits or across other sites — it counts page views, roughly where in the world they come from, and how quickly pages load. It isn't used to build a profile of you, track you individually, or serve ads. The only other outside request the app makes is a weather forecast (via Open-Meteo), which needs no personal data to answer.
