These Terms form a binding agreement between you and SIA Kellosolutions, registration number [REG. NO.], registered at [STREET, CITY, POSTAL CODE], Latvia ("Kellosolutions", "we", "us"), governing your use of the Lodestone mobile application ("the App").
By downloading or using the App you accept these Terms. If you do not accept them, do not use the App.

⚠️ Lodestone is not a safety device.
The App reads your phone's built-in magnetometer. A magnetometer is not a metal detector search coil and it is not a cable locator. It has significant, unavoidable limitations:
It detects ferromagnetic materials and permanent magnets only — iron, steel, nickel. It cannot reliably detect aluminium, copper, brass, gold or silver, because those metals are not magnetic.
Its useful range is typically a few centimetres.
It cannot detect plastic pipe, PEX, PVC conduit, fibre-optic cable, or unenergised non-ferrous wiring at all.
Accuracy varies significantly between device models, and a magnetic phone case or accessory can disable it entirely.
Never drill, cut, saw, nail or dig based on this App. Always verify with a professional cable and pipe locator, consult building plans, and contact your utility locating service before breaking any surface. Treat every wall as if it contains live wiring and every ground as if it contains a gas line.
If you are not prepared to accept this, do not use the App.
We grant you a limited, personal, non-exclusive, non-transferable, revocable licence to install and use the App on devices you own or control, for your own non-commercial use, subject to these Terms and to the rules of the app store you downloaded it from.
You must not: reverse engineer, decompile or disassemble the App except to the extent that applicable law expressly permits it; remove proprietary notices; rent, lease, sublicense or resell it; use it to build a competing product; access our servers other than through the App; or attempt to circumvent rate limits, quotas or the subscription paywall.
All intellectual property in the App, including its source code, design, brand and content, remains ours or our licensors'. Nothing here transfers ownership.
Your content — your notes, photos and saved finds — remains yours. We claim no ownership of it and, as set out in the Privacy Policy, we do not store it.
You must be at least 13 years old to use the App, or older if the law of your country requires it. If you are under 18, you must have permission from a parent or guardian, who accepts these Terms on your behalf.
The App is free to download and includes free features subject to usage limits (currently 10 saved finds and 3 AI identifications per day). Lodestone Pro removes those limits and unlocks additional features. We may change the composition of the free and paid tiers, but we will not remove a feature from a subscription you have already paid for during its current term.
Payment is charged to your Apple ID or Google Play account. We never receive your payment card details.
Subscriptions renew automatically at the then-current price unless you cancel at least 24 hours before the end of the current period. Your account is charged for renewal within 24 hours of the period ending.
Where a free trial is offered, any unused portion is forfeited if you purchase a subscription during the trial. Cancel at least 24 hours before the trial ends to avoid being charged.
Manage or cancel in your Apple ID subscription settings or Google Play subscriptions. Deleting the App does not cancel a subscription.
Refunds are handled by Apple or Google, not by us. We have no technical ability to issue a refund for a store purchase. Contact Apple Support or Google Play Support. We will assist where we can but cannot guarantee an outcome.
If you are a consumer in the European Union, you normally have 14 days to withdraw from a distance contract for digital content.
By purchasing a subscription and gaining immediate access to Pro features, you expressly request immediate performance and acknowledge that you lose the right of withdrawal once performance has begun, in accordance with Directive (EU) 2011/83 as amended by Directive (EU) 2019/2161. This does not affect any statutory rights you have in respect of digital content that does not conform to the contract.
We may change subscription prices. Changes take effect at the start of the next billing period and only after we have given you notice through the App or the store, with an opportunity to cancel. Where the applicable store requires your explicit consent to a price rise, the subscription will not renew at the new price without it.
The AI Identify and AI Field Assistant features use a third-party large language model.
You are interacting with an AI system, not a person. We disclose this in accordance with Article 50 of Regulation (EU) 2024/1689 (the EU AI Act).
You acknowledge and agree that:
AI output is a probabilistic estimate, not a measurement or a professional opinion.
It may be incorrect, incomplete, or confidently wrong.
It is not engineering, construction, electrical, safety, legal, financial or archaeological advice.
You must not rely on it for any decision affecting safety or property. A safety flag that does not appear is not evidence that a hazard is absent.
AI features require an internet connection and may be unavailable, rate-limited, or changed. We may suspend them if a provider withdraws service, if costs become unsustainable, or if the feature is being abused.
You must not use the AI features to generate unlawful, abusive, infringing or deceptive content, to attempt to extract our prompts or system instructions, or to submit images of other people without their consent.
You must not use the App to break the law. In particular, you are responsible for ensuring that any detecting, searching or excavation you do is lawful where you are — including obtaining landowner permission and complying with any heritage, archaeological, protected-site or utility legislation that applies. Many jurisdictions criminalise detecting on protected land.
You must not use the App to interfere with critical infrastructure, to locate utilities in order to damage them, or to defeat security or screening systems.
You are solely responsible for your compliance and for any consequences of it.
To the fullest extent permitted by law, the App is provided "as is" and "as available", without warranties of any kind, express or implied, including fitness for a particular purpose, merchantability, accuracy and non-infringement.
We specifically do not warrant that the App will detect any given object, that readings are accurate, that it will function identically across devices, or that it will be uninterrupted or error-free.
If you are a consumer, this section does not limit your mandatory statutory rights under the consumer protection law of your country of residence, including your rights in respect of the conformity of digital content and services.
Nothing in these Terms excludes or limits our liability for death or personal injury caused by our negligence, for fraud or fraudulent misrepresentation, or for any other liability that cannot lawfully be excluded or limited.
Subject to that, and to the fullest extent permitted by law:
(a) We are not liable for any damage to property, injury, loss, cost or expense arising from drilling, cutting, sawing, nailing, excavating or any other physical act undertaken in reliance on the App or its AI output. You accept sole responsibility for such decisions.
(b) We are not liable for indirect, incidental, special, consequential, exemplary or punitive damages, for loss of profits, revenue, data, goodwill or anticipated savings, however arising.
(c) Our total aggregate liability arising out of or in connection with the App is limited to the greater of (i) the amount you paid us for the App in the twelve months preceding the event giving rise to the claim, or (ii) EUR 50.
(d) We are not liable for failures caused by your device hardware, magnetic interference in your environment, third-party services, or your failure to verify readings with a professional tool.
If you are a consumer, we are liable for foreseeable loss caused by our breach; we are not liable for loss that was not foreseeable at the time the contract was made.
You agree to indemnify us against claims, damages and reasonable legal costs arising from your breach of these Terms, your unlawful use of the App, or your infringement of a third party's rights. This does not apply to the extent the claim arises from our own breach or negligence, and, if you are a consumer, only to the extent permitted by the consumer law applicable to you.
We may modify, suspend or discontinue any part of the App at any time. If we discontinue a paid feature during a subscription term you have already paid for, you may cancel and request a pro-rata refund through the relevant app store.
We may terminate your licence immediately if you materially breach these Terms. You may terminate at any time by deleting the App. Sections 5, 7, 8, 9, 11 and 12 survive termination.
We may update these Terms. Material changes will be notified in the App at least 30 days before they take effect where the change is to your disadvantage. Continued use after the effective date means you accept them. If you do not accept, stop using the App and cancel any subscription.
Apple. These Terms are between you and Kellosolutions only, not Apple. Apple has no obligation to provide maintenance or support for the App. If the App fails to conform to any applicable warranty, you may notify Apple, and Apple may refund the purchase price; to the maximum extent permitted by law, Apple has no other warranty obligation. Kellosolutions, not Apple, is responsible for product liability claims, claims that the App fails to meet legal requirements, and claims under consumer protection or privacy law. Kellosolutions, not Apple, is responsible for investigating and resolving any third-party intellectual property infringement claim relating to the App. You represent that you are not located in a country subject to a US Government embargo or designated as terrorist-supporting, and are not on any US Government prohibited-parties list. Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you.
Google. Your use of the App obtained from Google Play is additionally subject to the Google Play Terms of Service. Google is not a party to these Terms and has no liability under them.
These Terms are governed by the laws of the Republic of Latvia, excluding its conflict-of-laws rules and the UN Convention on Contracts for the International Sale of Goods.
If you are a consumer, this choice does not deprive you of the protection of any mandatory provisions of the law of the country in which you are habitually resident, and you may bring proceedings in the courts of that country.
Otherwise, the courts of Riga, Latvia have exclusive jurisdiction.
Before litigating, please contact info@kellosolutions.com. Most issues can be resolved by email within a few days.
EU consumers may also contact the Latvian Consumer Rights Protection Centre (Patērētāju tiesību aizsardzības centrs, PTAC), Brīvības iela 55, Riga, LV-1010, ptac@ptac.gov.lv, or the consumer protection body in their own country. We are not obliged to, and do not currently, participate in alternative dispute resolution before a consumer arbitration body.
If any provision is held unenforceable, the rest remains in force and the unenforceable provision is replaced by one that most closely reflects the original intent. Our failure to enforce a provision is not a waiver. You may not assign these Terms; we may assign them to a successor in a merger or acquisition, on notice to you. These Terms and the Privacy Policy are the entire agreement between us regarding the App.
In the event of conflict between a translation and the English version, the English version prevails.
