Lost Then Found is a free NFC dog tag service operated as a solo project in the United Kingdom. We supply physical NFC tags and provide an online platform that allows dog owners to create a profile for their dog and receive alerts when the tag is scanned by a finder.
By ordering a tag, claiming a tag, or using this website in any way, you agree to these terms.
We provide:
We do not provide GPS tracking, live location monitoring, or any guarantee that your dog will be found or returned. Lost Then Found is a tool to help - not a guarantee of any outcome.
Lost Then Found is not a microchip service, a GPS tracker, or an insurance product. Please note that under the Control of Dogs Order 1992, dogs in public places in England and Wales must wear a collar displaying the owner's name and address. How you satisfy that requirement is your responsibility.
You are responsible for keeping your PIN secure. We cannot recover lost PINs - if you lose access to your account, contact us and we will verify your identity and help you regain access.
You are responsible for keeping your dog's profile accurate and up to date, including your contact details. We are not liable for failed notifications caused by incorrect information on your profile.
You must be 18 or over to create an account.
You must not use Lost Then Found to:
We reserve the right to suspend or delete accounts that breach these terms without notice.
Notifications - including SMS and email alerts - are sent on a best-effort basis. We use third-party providers (Brevo) to deliver notifications and cannot guarantee delivery in all circumstances. Network issues, incorrect contact details, or third-party outages may affect delivery. We are not liable for any loss or harm resulting from a missed or delayed notification.
SMS alerts require a valid UK mobile number and are subject to network availability. We reserve the right to adjust notification methods as the service evolves.
Tags are free. You pay postage only at the time of ordering. Postage is non-refundable once an order has been dispatched. If your tag does not arrive within a reasonable time, get in touch and we will arrange a replacement.
Replacement tags are also subject to a postage charge and follow the same terms.
Contributions made through the support page are voluntary and non-refundable. They are not donations to a registered charity and are not tax-deductible. Contributions go towards running costs including hosting, SMS credits, and tag materials.
Lost Then Found is provided as-is. We make no warranties, express or implied, about the reliability, accuracy, or fitness for purpose of the service.
To the fullest extent permitted by law, we are not liable for:
Nothing in these terms excludes liability for death or personal injury caused by negligence, or for fraud.
How we handle your personal data is covered in our privacy policy. By using Lost Then Found you agree to that policy.
We reserve the right to change, suspend, or discontinue the service at any time. If we ever close Lost Then Found permanently, we will give reasonable notice to all registered owners so they can make alternative arrangements. The profile URL on your tag is permanent for as long as the service runs.
We may update these terms from time to time. The current version is always available at this URL. Continued use of the service after changes are posted means you accept the updated terms.
These terms are governed by the laws of England and Wales. Any disputes will be subject to the exclusive jurisdiction of the courts of England and Wales.
