Terms of Service
Effective Date: July 22, 2026 | Previous version: July 27, 2025
1. Introduction
These Terms of Service (“Terms”) govern your access to and use of the Dialvia Limited services (“Service”), including our website, mobile applications, and related APIs. By registering for or using the Service, you agree to these Terms. If you do not agree, please do not use the Service.
Section 5 (Acceptable Use) sets out conduct that is strictly prohibited. Breach of Section 5 may result in immediate suspension or termination of your account without notice and without refund, as described in Section 8.
2. Definitions
- User: Any individual or entity who registers for or uses the Service.
- Credits: Units of value purchased by Users to place calls.
- Auto Top-Up: Optional feature that automatically replenishes Credits when a User’s balance falls below a threshold they configure.
- Artificial Traffic: Calls or call attempts that are not the result of a genuine, person-to-person communication initiated by you for its own sake — including calls generated by software, scripts, or automation, and calls placed for the purpose of generating call volume, revenue, or billing events rather than to communicate with the person called.
- Traffic Pumping: Any scheme in which call traffic is artificially generated or directed to particular numbers or number ranges so that a person other than the terminating carrier’s intended recipient derives revenue, a share of revenue, or any other benefit from the call. This includes International Revenue Share Fraud and access stimulation.
- Prohibited Traffic: Artificial Traffic, Traffic Pumping, and any other use of the Service prohibited by Section 5.
3. Eligibility & Account Registration
- You must be at least 18 years old, or the higher minimum age required by your local jurisdiction, and legally capable of entering into a binding contract.
- You agree to provide accurate, current, and complete information during registration and to keep it updated. Registering with false, misleading, or another person’s identifying information is a material breach of these Terms.
- One account per person. You may hold only one personal account. You may not create, operate, or control multiple accounts, whether directly or through another person, and whether or not the accounts share an email address, phone number, device, or payment method.
- No coordinated accounts. Operating a group of accounts in concert — for example by funding them from the same payment instrument, directing them to the same destinations, or using them to spread activity that would otherwise exceed the limits of a single account — is prohibited. Where we identify such a group, we may suspend every account in it.
- Each account is non-transferable and is for your own personal or business use only. You may not sell, rent, lend, or share your account or account credentials, and you may not resell the Service or make it available to third parties as a calling service of your own.
- You are responsible for all activity that occurs under your account and for keeping your credentials secure. Notify us immediately at [email protected] if you suspect unauthorized access.
4. Verified Caller IDs
- You may only verify and display a telephone number as your caller ID if you own that number or are expressly authorized by its owner to use it.
- You may not transmit false, misleading, or inaccurate caller identification information, or use caller ID with intent to defraud, cause harm, or wrongfully obtain anything of value. Doing so may also breach applicable law, including the UK Communications Act 2003 and the US Truth in Caller ID Act.
- We may withdraw verification of any number at any time, and may require re-verification.
5. Acceptable Use
The Service is provided for genuine personal and business communication. The following are strictly prohibited.
5.1 Automated and programmatic calling
- Placing calls by means of any script, bot, macro, automated dialer, robodialer, predictive dialer, or other software or process that initiates calls other than through the ordinary user interface, one call at a time, by your own deliberate action.
- Auto-dialing, sequential dialing, or random dialing — including dialing numbers in numerical order, dialing multiple numbers within the same number block or range, or scanning number ranges to find numbers that answer (“war dialing”).
- Repeatedly redialing a number after a failed, busy, unanswered, or rejected attempt at a rate or volume beyond ordinary human retry behaviour.
- Generating high volumes of call attempts, whether or not the calls connect, including call bombing, call flooding, or any activity that burdens our systems or those of our carriers.
- Continuing to place calls after receiving a rate-limit, error, or blocking message, or attempting to work around any such control.
5.2 Traffic pumping and revenue-share fraud
- Any form of Traffic Pumping, including International Revenue Share Fraud (IRSF), access stimulation, and artificial inflation of traffic.
- Placing calls to any number from which you, or any person or entity connected with you, receive or expect to receive payment, revenue share, commission, or any other benefit that is derived from the call itself, its duration, or its termination.
- Placing calls to premium-rate, revenue-share, audiotext, chat-line, or similar numbers for the purpose of generating call volume, billing events, or duration, rather than to communicate with the person called.
- Any arrangement, whether or not with third parties, whose purpose or effect is to convert Credits into revenue on the terminating side of a call.
- Generating Artificial Traffic of any kind, or assisting, procuring, or facilitating another person in doing so.
5.3 Unlawful, abusive, and unwanted calling
- Using the Service for any unlawful purpose, or in breach of any applicable telecommunications, privacy, marketing, consumer-protection, or anti-fraud law of any jurisdiction connected with the call.
- Telemarketing, cold calling, market research, political or charitable solicitation, debt collection, or any bulk or unsolicited calling, including pre-recorded or artificial-voice messages, without all consents and registrations required by law in the recipient’s jurisdiction.
- Calls that harass, threaten, abuse, stalk, defraud, deceive, impersonate, or intimidate any person, or that are made repeatedly to a person who has asked not to be contacted.
- Fraud of any kind, including scam, phishing, or social-engineering calls, and “wangiri” or missed-call callback schemes.
- Distributing malware, or any attempt to interfere with, disrupt, or gain unauthorized access to the Service, our carriers’ networks, or any other system or network.
5.4 Technical restrictions
- Accessing the Service other than through the interfaces we provide, or using scraping, crawling, or automated data-collection tools against the Service.
- Reverse engineering, decompiling, or disassembling any part of the Service, or attempting to discover, probe, or circumvent our fraud-detection, rate-limiting, credit, or authentication controls.
- Using proxies, VPNs, virtual or disposable numbers, or false location information to evade geographic restrictions, verification requirements, pricing, or enforcement action.
- Reselling, sublicensing, or providing the Service to third parties, or operating it as a call centre, service bureau, or wholesale carrier.
5.5 Sanctions and trade controls
- You may not use the Service if you are subject to sanctions administered by the United Kingdom, the European Union, the United States, or the United Nations, or if you are located in a comprehensively sanctioned territory.
- You may not place calls to any person or entity you know or ought reasonably to know is subject to such sanctions.
5.6 Emergency services
- The Service does not support calls to emergency services such as 999, 112, or 911, and calls to those numbers are blocked. The Service is not a replacement for a telephone line and cannot be relied upon in an emergency.
- You must at all times have an alternative means of contacting emergency services. We are not able to determine your physical location and cannot route emergency calls or receive return calls from emergency operators.
- You may not attempt to circumvent this restriction, and you may not place hoax, prank, or nuisance calls to any emergency or public-safety number.
6. Fraud Prevention & Monitoring
- Automated controls. We operate automated systems that analyse call metadata — such as destination numbers, the timing, frequency, duration, and outcome of call attempts, and patterns across accounts — to detect Prohibited Traffic. We do not listen to or record the content of your calls for this purpose.
- Limits. We may apply rate limits, velocity limits, destination restrictions, spending limits, and per-account or per-destination caps, and may change them at any time without notice where we reasonably consider it necessary to prevent abuse.
- Automatic action. Where our systems identify activity consistent with Prohibited Traffic, calls may be blocked and your account may be suspended automatically. If you believe a restriction has been applied in error, contact [email protected].
- Verification. We may at any time require you to verify your identity, your ownership of a payment method, or your ownership of a telephone number, and may suspend access to the Service until you do so.
- Disclosure. We may share account, call, and payment information with our carriers, payment processors, regulators, and law enforcement where reasonably necessary to investigate or prevent fraud, to comply with a legal obligation, or to establish or defend legal claims. Our handling of personal data is described in our Privacy Policy.
7. Credits & Billing
- All calls consume Credits based on duration, rounded up to the next full minute.
- Credit rates vary by destination and are published on our site.
- Payments are processed by Stripe; we do not store raw payment information.
- Credits have no cash value, are not a deposit or electronic money, do not earn interest, and are not transferable between accounts or to any other person.
- Payment method. You may only use a payment method that you are authorized to use. Using a stolen, unauthorized, or misappropriated payment instrument, or using one payment instrument to fund multiple accounts in breach of Section 3, is a material breach of these Terms.
- Chargebacks. If you dispute a charge, contact us first. Initiating a chargeback for Credits that were delivered and used is a breach of these Terms. Where a chargeback is raised, we may suspend your account pending resolution, and you remain liable for the disputed amount together with any fees charged to us by our payment processor.
- Recovery of losses. Where your breach of Section 5 causes us to incur carrier charges, fraud-related fees, fines, or third-party claims, you are liable to us for those amounts, and we may set them off against any balance on your account.
8. Auto Top-Up
- Optional Feature: Users may enable Auto Top-Up on the Buy Credits page after saving a payment method.
- Threshold & Target: You choose a balance threshold (when balance goes below) and a target amount (balance to restore to). When your balance falls below the threshold, Auto Top-Up charges your saved card off-session for the difference needed to reach your target.
- Card on File: Add a card via the dedicated card setup flow on the Buy Credits page—no credit purchase is required to save your payment method.
- How to Enable: Add a card, then enable auto top-up and configure your threshold and target.
- How to Disable: Turn off the toggle on the Buy Credits page or remove your saved card.
- Records: All top-up transactions appear in your Billing History with date, amount, and credits added.
- Suspension: We may disable Auto Top-Up on your account at any time where we reasonably suspect Prohibited Traffic or a payment issue, in order to prevent further charges being incurred.
9. Enforcement, Suspension & Termination
- Our remedies. Where we reasonably believe you have breached these Terms — and in particular Section 3 or Section 5 — we may take any of the following steps, alone or together: block individual calls or destinations; apply or reduce limits on your account; disable Auto Top-Up; withdraw caller ID verification; suspend your account; terminate your account permanently; and refuse you further access to the Service.
- Immediate action. Where the suspected breach involves Prohibited Traffic, payment fraud, or a risk of harm to us, our carriers, or third parties, we may act immediately and without prior notice. We will tell you that action has been taken, but we are not obliged to disclose the details of our detection methods.
- Related accounts. Where we terminate an account for breach of Section 3 or Section 5, we may also suspend or terminate any other account we reasonably believe is controlled by you or operated in concert with yours.
- Credits on termination for breach. If we terminate your account for a material breach of these Terms, any unused Credits are forfeited to the extent of the loss, cost, or liability we reasonably incur as a result of your breach. We will refund any balance remaining after that amount has been applied. This does not affect your legal rights if we terminate your account other than for your breach, in which case we will refund your unused Credits.
- Reinstatement. An account terminated for Prohibited Traffic will not be reinstated. Payment for the Service, or the fact that some use of an account was legitimate, does not entitle you to reinstatement.
- Survival. Sections 7, 9, 11, 12, 13, 14, 15, and 16 survive termination.
10. Analytics & Data Collection
- Analytics Services: We use PostHog analytics to understand how users interact with our Service and to improve functionality.
- Consent-Based Tracking: Analytics data collection requires your explicit consent through our cookie banner.
- Data Usage: Analytics data helps us identify usage patterns, technical issues, and opportunities for service enhancement.
- Opt-Out: You may decline analytics at any time without affecting your ability to use core Service features.
- Privacy Compliance: Our analytics practices comply with applicable privacy laws and regulations. Fraud prevention under Section 6 is carried out on the basis of our legitimate interests and is not subject to analytics consent.
11. Refunds & Cancellations
All credit purchases are final after 7 days from account creation. To request a refund for errors or disputes, contact us at [email protected]. Refunds, if granted, may be subject to verification.
Referral Program Exception: Users who sign up through a referral link are not eligible for the 7-day money-back guarantee. This exclusion is necessary to prevent abuse of our referral reward system where referrers earn discount codes when referred users make purchases.
Prohibited Traffic Exception: No refund is payable in respect of Credits consumed by, or an account terminated for, Prohibited Traffic. Section 9 governs the treatment of unused Credits on termination for breach.
Nothing in this section affects any statutory right of cancellation you may have as a consumer, or your legal rights in respect of a Service that is not provided with reasonable care and skill.
12. Disclaimers
THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE”. TO THE MAXIMUM EXTENT PERMITTED BY LAW, WE DISCLAIM ALL WARRANTIES, CONDITIONS, AND REPRESENTATIONS NOT EXPRESSLY SET OUT IN THESE TERMS, WHETHER EXPRESS OR IMPLIED, INCLUDING ANY IMPLIED WARRANTY OF MERCHANTABILITY, SATISFACTORY QUALITY, FITNESS FOR A PARTICULAR PURPOSE, OR NON-INFRINGEMENT.
We do not warrant that the Service will be uninterrupted, error-free, or secure, that any call will connect or be of any particular quality, or that any number will be reachable. Call quality depends on your internet connection, your device, and third-party networks outside our control. If you are a consumer, this section does not affect your statutory rights.
13. Limitation of Liability
TO THE MAXIMUM EXTENT PERMITTED BY LAW, DIALVIA AND ITS AFFILIATES SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, OR CONSEQUENTIAL DAMAGES ARISING OUT OF YOUR USE OF THE SERVICE, INCLUDING BUT NOT LIMITED TO INTERRUPTED CALLS, DATA LOSS, LOST PROFITS, OR THIRD-PARTY ACTIONS.
Subject to the paragraph below, our total aggregate liability arising out of or in connection with these Terms or the Service, whether in contract, tort (including negligence), or otherwise, is limited to the greater of (a) the total amount you paid us in the twelve months preceding the event giving rise to the claim, and (b) GBP 100.
Nothing in these Terms limits or excludes our liability for death or personal injury caused by our negligence, fraud or fraudulent misrepresentation, or any other liability that cannot lawfully be limited or excluded. If you are a consumer, we are responsible for loss or damage you suffer that is a foreseeable result of our breach of these Terms or our failure to use reasonable care and skill, and nothing in these Terms affects your statutory rights.
14. Indemnification
You agree to indemnify, defend, and hold harmless Dialvia and its officers, directors, employees, and agents from any claims, liabilities, fines, penalties, carrier charges, or expenses (including reasonable legal fees) arising from your breach of these Terms, your use of the Service, or any Prohibited Traffic originating from your account. If you are a consumer, this obligation applies only to the extent the claim arises from your deliberate breach or negligence.
15. Modifications & Termination
We may modify or discontinue the Service, in whole or in part, at any time with or without notice. We may terminate or suspend your access if you violate these Terms or for any lawful reason.
We may amend these Terms from time to time. Where a change is material and adverse to you, we will give you reasonable notice by email or through the Service before it takes effect, except where the change is required by law or is needed to address a security or fraud risk, in which case it may take effect immediately. Your continued use of the Service after a change takes effect constitutes acceptance. If you do not accept a change, you may stop using the Service and request a refund of your unused Credits.
16. General
- Entire agreement: These Terms, together with our Privacy Policy, form the entire agreement between you and us regarding the Service.
- Severability: If any provision is found unenforceable, the remaining provisions continue in full force, and the unenforceable provision applies to the maximum extent permitted.
- No waiver: Our failure to enforce any provision is not a waiver of our right to do so later.
- Assignment: You may not assign or transfer these Terms. We may assign them to an affiliate or in connection with a merger, acquisition, or sale of assets.
- Force majeure: We are not liable for any failure or delay caused by events beyond our reasonable control, including carrier or network outages.
- Third parties: No person other than you and us has any right to enforce these Terms.
17. Governing Law
These Terms are governed by the laws of England and Wales, without regard to conflict of law principles. Any disputes shall be resolved in the courts located in London, UK. If you are a consumer resident elsewhere in the UK or in the EEA, you retain the benefit of any mandatory protections of the law of your country of residence and may bring proceedings in your local courts.
