Terms of Service
Last updated: 18 October 2026
By using the Muld mobile app ("the app"), you agree to these terms. If you do not agree, do not use the app.
1. The app
Muld is a mobile app for hobby metal-detectorists. It provides maps, find-logging, session tracking, and the on-map display of protected and heritage areas. Some features are country-specific: in Denmark the app offers optional submission of finds to the DIME national register; in England it provides Treasure Act and Portable Antiquities Scheme reference information but does not submit finds on your behalf. The country whose data and rules apply is the one you select in the app.
The app is operated by the owner of muld.dev ("we", "us").
Contact: hello@muld.dev.
2. Eligibility
You must be at least 13 years old to use the app. By using the app, you confirm you meet this requirement.
3. Account
- You are responsible for keeping your account credentials secure.
- One account per person.
- You must provide a valid email address.
- We may suspend accounts that violate these terms.
4. Subscriptions
4.1 Free tier
Core features are free: map, find logging, journal, basic layers.
4.2 Muld+ subscription
Muld+ unlocks additional features (LiDAR layer, historical map layers, offline map downloads, and other Muld+ content). Purchased via Google Play or the App Store, billed through your Google or Apple account.
4.3 Renewal and cancellation
- Subscriptions auto-renew unless cancelled at least 24 hours before the end of the current period.
- Cancel any time via Google Play → Subscriptions, or on iPhone via Settings → your name → Subscriptions → Muld → Cancel Subscription. Cancellation takes effect at the end of the current billing period.
- Prices may change; we will notify you in-app before any price increase takes effect.
4.4 Refunds
Refunds are governed by the policy of the store you purchased through. Google Play offers a 48-hour refund window; App Store refunds are requested from Apple at reportaproblem.apple.com and are decided by Apple. Outside those channels, contact hello@muld.dev and we will consider refund requests on a case-by-case basis but are not obliged to grant them.
4.5 Free trials
If we offer a free trial, you will be charged the regular subscription price at the end of the trial unless you cancel before it ends.
5. Acceptable use
You agree NOT to:
- Use the app for any unlawful purpose.
- Reverse-engineer, decompile, or attempt to extract the source code.
- Submit false or misleading data to DIME or any national find register via the app.
- Use the app to harass, dox, or harm others.
- Attempt to disrupt the app's infrastructure (proxy, auth, storage).
6. Detecting legality — your responsibility
Metal-detecting is governed by the law of the country you detect in. You are solely responsible for ensuring that your detecting activities are legal. The app shows protected and heritage areas to help you, but it is not a legal authority — the data may be incomplete, out of date, or imprecisely positioned. Always verify with official sources before detecting near a protected area.
6.1 Denmark
- You must have explicit permission from the landowner before detecting on private land.
- Protected zones (fortidsminder, beskyttede sten- og jorddiger, and other protected areas) are subject to strict rules.
- Finds of cultural-historical significance ("danefæ" — treasure trove) must be reported to the National Museum (Nationalmuseet) under Danish law. The DIME submission feature helps with this but does not replace your legal obligation to report.
6.2 England
- You must have the landowner's (or occupier's) permission before detecting on any land. There is no general right to detect.
- Using a metal detector on a scheduled monument without written consent is a criminal offence under the Ancient Monuments and Archaeological Areas Act 1979. The app shows scheduled monuments from the National Heritage List for England as guidance only; it does not grant consent and may not be complete.
- Possible treasure must be reported within 14 days under the Treasure Act 1996 — in practice to your local Finds Liaison Officer, who notifies the coroner. Muld does not report on your behalf.
- Recording your finds with the Portable Antiquities Scheme (PAS) is voluntary and best practice; you do this yourself at finds.org.uk, not through the app.
- Different rules apply in Scotland, Wales and Northern Ireland; Muld's England data and guidance do not cover them.
We provide tools to help you detect responsibly, but the legal responsibility for every action you take with the app is yours.
7. Intellectual property
- The app, including code, design, and content created by us, is our intellectual property.
- Map data is from public and third-party sources, used under their respective licences:
- Denmark: Datafordeler / Geodatastyrelsen (public geospatial data); Dataforsyningen / Styrelsen for Dataforsyning (historical maps, ortophotos, LiDAR); SLKS (protected-zone polygons).
- England: Environment Agency (national LiDAR, under the Open Government Licence); Historic England (National Heritage List for England); historic Ordnance Survey maps (out of Crown copyright); GB1900 (place-names, Creative Commons).
- Both: OpenStreetMap contributors (base map, ODbL); Esri (World Imagery, where used as an aerial base).
- You retain ownership of your own content (finds, photos, notes). This content is stored locally on your device — we don't host it, so we claim no licence over it. Anything you choose to submit to DIME is governed by DIME's terms.
8. Disclaimers
The app is provided "as is" and "as available". We do not warrant that:
- The app will be uninterrupted, error-free, or available at all times.
- The map data is accurate, current, or complete.
- The protected-zone map layers are complete, current, or correctly positioned. Always verify legality independently.
9. Limitation of liability
To the maximum extent permitted by law:
- We are not liable for indirect, incidental, or consequential damages.
- Our total liability for any claim related to the app is limited to the amount you paid us in the 12 months preceding the claim (or zero if you are on the free tier).
- Nothing in these terms limits liability for gross negligence, intentional misconduct, or anything else that cannot be limited under Danish law.
10. Termination
- You may stop using the app at any time and delete your account via the in-app Settings.
- We may suspend or terminate your access if you violate these terms.
- Sections 5 (acceptable use), 6 (legality), 7 (IP), 8 (disclaimers), 9 (liability), and 12 (governing law) survive termination.
11. Changes to these terms
We may update these terms. The "Last updated" date at the top reflects the most recent change. Material changes will be announced in-app on the next launch after the change. Continued use after the change means you accept the new terms.
12. Governing law and disputes
These terms are governed by Danish law, and disputes are subject to the exclusive jurisdiction of the Danish courts, with the City Court of Copenhagen as the court of first instance.
If you are a consumer, this does not deprive you of the protection of the mandatory consumer-law provisions of the country in which you live, and you may be entitled to bring proceedings in your local courts. In particular, if you are a consumer resident in the United Kingdom, you keep the benefit of any mandatory provisions of UK consumer law (including the Consumer Rights Act 2015) and may bring proceedings in the UK courts.
