Terms of Service

1. Who we are

Droptunnel is a file and text transfer service owned and operated by Denovi Ltd, a private limited company registered in England and Wales under company number 09859016. Our registered office is The Garth, Bucklebury, Reading, England, RG7 6SB.

Contact support@droptunnel.com for support and legal@droptunnel.com for legal notices.

2. Your agreement and eligibility

By accessing, creating, joining, or using a tunnel, or purchasing Droptunnel Plus, you confirm that you have read and agree to these Terms and our Privacy Notice. If you do not agree, do not use the service.

You must be at least 18 years old and legally capable of entering into a contract. If you use Droptunnel for an organisation, you confirm that you are authorised to bind it; “you” then includes that organisation.

You are responsible for ensuring that your use is lawful where you are located and where your recipient is located. We do not represent that Droptunnel is appropriate or lawful in every country.

3. How the service works

Droptunnel creates an ephemeral connection between two browsers. It uses a short tunnel code, an encrypted browser handshake, WebRTC where available, and Cloudflare infrastructure for connection coordination and encrypted relay fallback.

Text and files are encrypted in the sender’s browser and decrypted in the recipient’s browser. We do not provide a cloud file library and do not intentionally write message or file contents to our billing database. Encrypted frames may pass transiently through our relay when a direct connection is unavailable. Limited technical and billing records are handled as described in the Privacy Notice.

Free tunnels currently permit files up to 200 MB each. A valid Plus browser pass currently raises the shared tunnel limit to 10 GB per file and allows the tunnel to remain active while eligible devices stay connected. Limits may also depend on browser, device, storage, network, and service constraints.

4. Security and important limitations

You understand and accept that:

• a tunnel code is a sensitive, short-lived credential and anyone who obtains it may attempt to connect;
• you must share codes only through a trusted channel and verify the intended recipient independently;
• a connected peer may learn network metadata, potentially including an IP address, through peer-to-peer connection establishment;
• we cannot inspect encrypted content for malware, accuracy, ownership, safety, or legality;
• you must scan received files and should only open content from people you trust; and
• no encryption, software, network, or security measure is guaranteed to be error-free, uninterrupted, or impossible to compromise.

Please report suspected vulnerabilities responsibly to security@droptunnel.com. Do not access other people’s data, degrade the service, or publicly disclose an unremediated vulnerability.

5. Your content and responsibility

As between you and us, you retain any rights you hold in content you transfer. You give us only the limited, temporary technical permission necessary to transmit encrypted data, coordinate the tunnel, operate a fallback relay, protect the service, and comply with law.

We do not select, endorse, verify, or control user content. You are solely responsible for having all rights, permissions, and lawful bases needed to send, receive, disclose, or otherwise process it. You are also responsible for the recipient you choose and for complying with confidentiality, privacy, intellectual-property, export-control, employment, professional, and sector-specific obligations.

6. Acceptable use

You must not use or facilitate use of Droptunnel to:

• create, possess, solicit, groom for, distribute, or facilitate child sexual abuse material or any exploitation or abuse of a child;
• promote, support, prepare, fund, or carry out terrorism or violent extremism;
• share non-consensual intimate images, sexual content without consent, or content that exploits another person;
• distribute malware, ransomware, spyware, malicious code, phishing material, stolen credentials, or instructions intended to compromise a system;
• threaten, harass, stalk, defraud, deceive, impersonate, extort, or unlawfully discriminate against anyone;
• infringe copyright, trade marks, privacy, confidentiality, data protection, publicity, contractual, or other rights;
• transfer content or technology in breach of sanctions, trade controls, court orders, or other applicable law;
• send content that is otherwise criminal, unlawful, or intended to facilitate an offence in any relevant country; or
• attack, probe, scan, scrape, overload, reverse engineer, interfere with, bypass restrictions on, or gain unauthorised access to the service, its users, or connected infrastructure.

These examples are not exhaustive. “Inappropriate” use includes use that creates a material risk of harm, abuse, exploitation, illegality, or disruption even if it is not expressly listed above.

7. Reports, safety, and enforcement

Report suspected illegal content or misuse through our Safety & Reporting page or email abuse@droptunnel.com. Include the time, tunnel code if still available, a clear description, and any evidence you can lawfully provide. Do not resend illegal material.

Because tunnels are encrypted and ephemeral, we may be unable to view, recover, remove, or verify content after transmission. This technical limitation does not restrict any action we may lawfully take when we receive a report or otherwise become aware of misuse.

To protect users, third parties, and the service, we may investigate, preserve available records, restrict requests or networks, revoke devices or Plus access, suspend or terminate access, make reports to competent authorities, and disclose available information when required or permitted by law. Serious breach may result in immediate action and, where legally permitted, no refund.

8. Droptunnel Plus

Plus costs £2.99 per month, including applicable taxes, and renews automatically each month until cancelled. Stripe displays and processes the payment before purchase. We do not receive your full card number.

A subscription can currently be linked to no more than five browsers. A signed browser pass stored locally is required to use Plus. Owner browsers can manage linked devices and, for paid subscriptions, billing. Other linked browsers cannot do so unless ownership is verified through the subscription email. A returning subscriber may also link a browser through a single-use link sent to that email. We may grant complimentary or promotional Plus access without recurring billing. You are responsible for protecting email access, device links, recovery links, and browser passes.

We may change the Plus price or features on reasonable advance notice. A price change will not apply before the next renewal stated in that notice. If you do not accept a change, cancel before it takes effect.

9. Starting, cancelling, and refunds

By selecting the checkout action, you expressly request that Plus begins immediately after payment and acknowledge that these Terms and the subscription information form part of your contract. You can cancel automatic renewal at any time through the Stripe customer portal. Ordinary cancellation takes effect at the end of the current paid billing period, and Plus remains available until then.

If consumer law gives you a cooling-off or cancellation right, you may exercise it by emailing support@droptunnel.com with the billing email and purchase date, or by making another clear statement. Where permitted by law and you requested immediate supply, we may deduct a proportionate amount for Plus supplied before cancellation.

Except where required by law or expressly agreed by us, payments are non-refundable and we do not provide voluntary refunds or credits for partial periods, unused service, lost browser passes, or network and device incompatibility. Nothing in these Terms limits mandatory consumer cancellation, refund, repair, repeat-performance, or price reduction rights.

10. Availability and changes

We aim to provide a reliable service, but do not promise continuous availability, any service level, preservation of a tunnel, successful delivery, a particular transfer speed, or compatibility with every device or network. Internet, browser, WebRTC, storage, Cloudflare, Stripe, and recipient conditions can affect the service.

We may maintain, update, limit, suspend, withdraw, or discontinue any free feature. We may suspend the service urgently for security, safety, legal, or operational reasons. Where reasonably possible, we will give paying users notice of a material adverse change.

11. Our intellectual property

Droptunnel, its software, design, branding, graphics, text, and other service materials are owned by or licensed to Denovi Ltd and are protected by intellectual-property law. Droptunnel is proprietary and is not represented as open-source software.

We grant you a personal, limited, revocable, non-exclusive, non-transferable right to use the service in accordance with these Terms. No other right or licence is granted.

12. Disclaimers

Nothing in these Terms excludes any promise or remedy that cannot lawfully be excluded. Subject to that, Droptunnel is provided “as is” and “as available.” To the fullest extent permitted by law, we exclude implied warranties and conditions beyond the obligation to exercise reasonable care and skill where it applies.

We do not warrant that content is safe, lawful, accurate, virus-free, or authorised; that encryption will never be compromised; or that a recipient is who they claim to be. You should maintain your own backups. Droptunnel is a transfer service, not a backup service.

13. Liability

Consumers

We are responsible for loss or damage that is a foreseeable result of our breach of these Terms or failure to use reasonable care and skill. We are not responsible for loss that was not foreseeable, for loss caused by your breach or another user, or for business loss arising from consumer use. We do not exclude or limit liability where doing so would be unlawful, including liability for death or personal injury caused by negligence, fraud, or fraudulent misrepresentation.

Business users

To the fullest extent permitted by law, we are not liable for loss of profit, revenue, business, opportunity, anticipated savings, goodwill, data, or any indirect or consequential loss. Our aggregate liability arising out of or relating to Droptunnel in any twelve-month period is limited to the total Plus fees you paid us during that period. The exclusions that cannot lawfully be made remain unaffected.

We are not responsible for user content, a user’s identity or conduct, loss caused by sharing a code or browser pass, malicious files, recipient actions, third-party services, internet failure, or events outside our reasonable control, except to the extent the law makes us responsible.

14. Business-user indemnity

If you use Droptunnel for business purposes, you will indemnify and keep indemnified Denovi Ltd, its officers, employees, and contractors against third-party claims, regulatory action, reasonable legal costs, liabilities, and losses arising from your content, your unlawful or unauthorised use, your infringement of another person’s rights, or your material breach of these Terms. This does not apply to the extent the claim was caused by our breach, negligence, or unlawful act.

Consumers do not give this business indemnity, but remain responsible for losses they cause through unlawful conduct or breach to the extent permitted by applicable law.

15. Suspension and termination

You may stop using free Droptunnel at any time and may cancel Plus as described above. We may restrict, suspend, or terminate access where we reasonably believe there has been a breach, security threat, unlawful activity, non-payment, legal requirement, or material risk to users, third parties, or the service.

Terms that by their nature should continue—including responsibility for content, intellectual property, liability, indemnity, disputes, and accrued payment obligations—survive termination.

16. Governing law and disputes

These Terms are governed by the laws of England and Wales. If you are a consumer, you retain any mandatory rights and may bring proceedings in any court available to you under applicable consumer law, including the courts of the part of the UK or country where you live where those rights apply. Business users submit to the exclusive jurisdiction of the courts of England and Wales.

Please contact legal@droptunnel.com first so we can try to resolve a dispute informally. This does not prevent either party seeking urgent relief or using a statutory complaints or enforcement route.

17. General terms

We may update these Terms for legal, security, operational, or product reasons. We will post the updated version and effective date. We will give Plus users reasonable notice of a material adverse change using the site or billing email where practicable. Continued use after a change takes effect constitutes acceptance; if you disagree, stop using the service and cancel Plus before renewal.

We may transfer our rights and obligations as part of a reorganisation, financing, sale, or transfer of the service, provided this does not reduce mandatory consumer rights. You may not transfer your contract without our written consent. If any provision is unenforceable, the remainder continues. Delay in enforcing a right is not a waiver. These Terms, the Privacy Notice, and checkout information are the entire agreement about the service, except for terms that law requires.
