Terms of service

Last updated November 6, 2026

These terms are an agreement between you and YB Tech Solutions Inc, 137 Clinton Ln Apt 4, Spring Valley, NY 10977 ("Sonaline", "we", "us"), for the use of Sonaline: its website, its apps for the web, Android, Windows and keypad phones, and the texting and calling it provides. By creating a workspace, signing in or using Sonaline you agree to them. Our Privacy policy explains how we handle information.

The service

Sonaline is a business texting and calling service. A business signs up for a workspace, and the people it invites use Sonaline to text and call the business's customers from the workspace's phone numbers, and to hear voicemail and recorded calls. Features differ by plan and change over time.

Accounts and workspaces

• The person who signs a business up is the workspace's first administrator and accepts these terms for the business. Administrators decide who has an account, what each person can see, and how long the workspace's messages and calls are kept.
• Keep your sign-in to yourself. You are responsible for what is done with your account; tell us at once if you think someone else has used it.
• You must give accurate information when you sign up and keep it up to date.

Using Sonaline lawfully

The business that owns a workspace is responsible for the texts and calls it sends through Sonaline. It must:

• have each recipient's consent before texting them, as the law and the carriers' rules require, and honour every opt-out at once (Sonaline stops texting a number that replies STOP to a workspace number);
• follow the laws that apply to texting and calling, including the Telephone Consumer Protection Act, and the carriers' and CTIA's messaging rules, including registering its texting with the carriers where required;
• not send spam, phishing, unlawful, harassing or deceptive messages, or content the carriers prohibit;
• tell callers when calls are recorded, where the law requires it;
• not try to get around Sonaline's limits or security, or use Sonaline to harm its network or other customers.

We may suspend texting or calling, or a workspace, to stop a breach of these rules, to protect the service or other customers, or when a carrier requires it.

Texts from Sonaline

Texts from Sonaline is the program under which Sonaline texts the people who use the Sonaline app from its own number: verification codes, for example to confirm that a mobile number you add for carrier calling is yours, and account, security, fraud and support messages for those who turn them on. Messages never carry marketing.

• Program: Texts from Sonaline: verification codes, account notifications, security alerts, fraud alerts and customer care messages about your Sonaline account.
• Opt-in for verification codes: you ask for a code by entering your mobile number and pressing Send code in Sonaline (Settings, Carrier calling, Add a phone number), next to the words "Sonaline will text a verification code to this number, one message per request. Msg & data rates may apply. Reply STOP to opt out, HELP for help."
• Opt-in for account, security, fraud and support messages: you turn on the switch under Texts from Sonaline in Settings, Notifications. It is off until you turn it on, it works only for a mobile number you have verified with a code, and it reads: "Text me account, security, fraud and support messages from Sonaline. Msg frequency varies. Msg & data rates may apply. Reply STOP to opt out, HELP for help." Turning it off withdraws your consent.
• Opt-in on sonaline.com/sms: the form at sonaline.com/sms needs no account. It has a Mobile number field and a checkbox, never ticked for you, that reads: "Text me account, security, fraud and support messages from Sonaline. Msg frequency varies. Msg & data rates may apply. Reply STOP to opt out, HELP for help.", with links to the Privacy policy and these Terms and the line "Not a condition of purchase." Pressing Text me a code sends one text: "Sonaline: your code to confirm texts from Sonaline is 482913. It expires in 10 minutes. Reply STOP to opt out." Entering that code on the page and pressing Confirm is your consent to these messages at that number, and we then send one confirmation text: "Sonaline: You're signed up for account, security, fraud & support texts. Msg frequency varies. Msg & data rates may apply. Reply HELP for help, STOP to opt out." Further messages go to that number once it is verified in a Sonaline account.
• Opt-in on the sign-up form: the sign-up form at sonaline.app/signup has an optional checkbox, never ticked for you and not required to sign up, beside an optional Mobile number field. It reads: "Text me account, security, fraud and support messages from Sonaline. Msg frequency varies. Msg & data rates may apply. Reply STOP to opt out, HELP for help." Ticking it is your consent to these messages at that number, which start only after you verify the number in the app with a code. Leaving it unticked changes nothing about your sign-up.
• Agreeing to receive any of these messages is not a condition of any purchase.
• Sample messages:
  • Verification code: "Sonaline: your verification code is 482913. It expires in 10 minutes."
  • Account notification: "Sonaline: The card on file for your workspace was declined. Update it in Settings > Billing to keep your service running. Reply STOP to opt out."
  • Security alert: "Sonaline: A new device signed in to your account (Chrome on Windows). If this wasn't you, change your password in Settings > Security. Reply STOP to opt out."
  • Fraud alert: "Sonaline: We paused international calling on your workspace after unusual activity. Review it in Settings > Security. Reply HELP for help, STOP to opt out."
  • Customer care: "Sonaline Support: Thanks for reaching out. Your new number is set up and ready to text. Reply here if you need anything else. Reply STOP to opt out."
• Frequency: verification codes, one message each time you ask for a code. Account, security, fraud and support messages: message frequency varies.
• Cost: message and data rates may apply.
• Opt-out: reply STOP (or STOPALL, UNSUBSCRIBE, CANCEL, END or QUIT) to stop receiving all messages from Sonaline at that number; the switch in Settings is turned off too. Reply START to receive verification codes again; the other messages need the switch turned on again.
• Help: reply HELP, or contact us at hello@sonaline.com or (845) 608-1220.
• Carriers are not liable for delayed or undelivered messages.

How we handle your mobile number is described in the Privacy policy.

Fees and billing

Plans are billed per person, per month, through our payment processor, Stripe, and texting usage is billed on top where the plan says so. Prices are shown when you sign up. We will tell a workspace before a price changes. A workspace can cancel at any time. Cancelling takes effect at the end of the current billing period, and the workspace keeps using Sonaline until then. Fees already paid are not refunded, except where the law requires it or where we end the service for a reason that is not the workspace's fault, in which case we refund the unused part of any period paid in advance. Usage charges, such as texting, are billed for what was used and are not refunded.

Your content

The messages, recordings, contacts and other content in a workspace belong to the business that owns it. You give us permission to store, process and transmit it only as needed to provide Sonaline to you, as the Privacy policy describes. We do not sell it or use it for advertising.

Phone numbers

A workspace may use numbers we provide or numbers it brings. Numbers are subject to the carriers' rules and availability. Numbers a workspace brings stay its own. When a workspace leaves, we will help move (port) its numbers to another provider when an authorized person of the workspace asks, as long as the account is paid up and the carriers allow it. A number we provided that is not ported out within 30 days after a workspace closes may be released back to the carrier and can then no longer be recovered.

Ending the service

A workspace may stop using Sonaline at any time. We may end or suspend a workspace that breaks these terms or does not pay. When a workspace is closed, its data is deleted as the Privacy policy describes.

Availability

We work to keep Sonaline running, but texting and calling depend on carriers, networks and devices outside our control, and we cannot promise that every message or call will be delivered or that the service will never be interrupted. Sonaline is not a replacement for a landline or mobile phone for emergency calls. An emergency call placed through Sonaline goes through the workspace's phone system and its carrier, and it may not connect, or may not pass your location to emergency responders, especially during a power, internet or network outage. Do not rely on Sonaline to reach emergency services; keep another way to call them, such as a mobile phone or a landline, and make sure everyone in your workspace knows this.

Disclaimers and limits of liability

No warranties. Sonaline is provided “as is” and “as available”. To the fullest extent the law allows, we disclaim all warranties, express or implied, including warranties of merchantability, fitness for a particular purpose, title and non-infringement, and any warranty that the service will be uninterrupted, error free or secure, or that every message or call will be delivered.

Limits of liability. To the fullest extent the law allows, neither we nor our suppliers are liable for any indirect, incidental, special, consequential or punitive damages, or for lost profits, revenue, data or business opportunities, arising from or related to Sonaline, even if we were told they were possible. Our total liability for any claim arising from or related to these terms or Sonaline is limited to the amount the workspace paid us for Sonaline in the 12 months before the claim arose. Some places do not allow some of these limits, so they may not all apply to you.

Your responsibility. You will defend and hold harmless YB Tech Solutions Inc and its officers and employees from any claim, loss or cost, including reasonable legal fees, arising from your content, the messages and calls your workspace sends, including any failure to get the consent the law requires, or your breach of these terms or of the law.

Governing law

These terms are governed by the laws of the State of New York, without regard to its conflict of laws rules. Before starting any legal action, you agree to contact us first so we can try to resolve the dispute informally within 30 days. Any dispute that is not resolved that way will be decided only in the state or federal courts located in Rockland County, New York, and both of us agree to those courts' jurisdiction.

Changes

When these terms change, we will update the date at the top of this page, and tell workspaces of any significant change before it takes effect. Continuing to use Sonaline after a change means accepting it.
