Sonaline

Privacy policy

Last updated November 6, 2026

Sonaline is a business texting and calling service. A business (a workspace) signs up, and its staff use Sonaline to text and call the business's customers. This page explains what information Sonaline handles, why, and what control you have over it.

Sonaline is a product of YB Tech Solutions Inc, 137 Clinton Ln Apt 4, Spring Valley, NY 10977 ("Sonaline", "we", "us"). Using Sonaline is also governed by our Terms of service.

Who is responsible for what

For the conversations a workspace has with its customers, the business that owns the workspace decides what is sent and kept; Sonaline processes that information on its behalf. For the accounts of the people who sign in, and for this website, Sonaline is responsible.

What we collect

How we use it

Only to provide the service: delivering messages and calls, showing a workspace its own conversations, sending notifications, keeping accounts secure, preventing abuse and runaway spending, and billing the workspace. We do not sell personal information, we do not use it for advertising, and we do not build profiles of the people a workspace texts.

Some features are done by automated speech and language services: writing out voicemail and recorded calls as text, summarising a recorded call, writing out a voice note, and suggesting a reply. Voicemail is written out when it arrives; the others run when someone asks for them. These services are provided partly by the cloud platform Sonaline runs on and partly by a specialist speech-transcription provider, and Sonaline sends them the audio or text only to get that work done.

Texts from Sonaline

Texts from Sonaline is the program under which Sonaline texts the people who use the Sonaline app from Sonaline's own number: verification codes, and, only for those who turn them on, account, security, fraud and support messages. That number never sends marketing, and it texts only a mobile number the person entered and verified themselves. There are two separate opt-ins, and the second can be given in three places: on the public form at sonaline.com/sms, on the public sign-up form, or with a switch in the app.

Examples of each kind of message:

We keep a log of the texts Sonaline's number sends, for up to 90 days, so we can tell whether a message was delivered. The log never holds a code itself and shows the phone number by its last four digits only. A number that replied STOP is kept so that it is not texted again.

Mobile information will not be shared with third parties or affiliates for marketing or promotional purposes. Text messaging originator opt-in data and consent will not be shared with any third parties. This applies to every text Sonaline sends, including the messages above and the texts a workspace sends through Sonaline.

Signing in with Google or Microsoft, and Google Contacts

If you sign in with Google, we receive your name, email address and profile picture from Google and use the verified email address only to find and open your existing Sonaline account.

If you sign in with Microsoft, we receive your name, email address and an account identifier from Microsoft and use them only to find and open your existing Sonaline account.

If you choose to connect Google Contacts, Sonaline reads your Google contacts' names, phone numbers and organisations so they appear in your workspace's contact book and stay up to date, and writes a contact's name and organisation back to your Google account when someone in your workspace saves or edits it. Sonaline never changes a Google contact's phone numbers, never copies your team's internal notes to Google, and never deletes anything from your Google account. The access Google grants is stored encrypted, and you can disconnect at any time from the app's settings, which revokes it at Google and, if you ask, removes the contacts it brought in.

Sonaline's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements. Google user data is used only to provide the features described above, is not shared except as needed to provide them, and is never used for advertising or to train AI models.

Who we share it with

Only the service providers needed to run Sonaline, and only for that purpose. We do not sell or rent personal information, and none of these providers may use it for its own marketing:

We may also disclose information when the law requires it.

How long we keep it

Each workspace sets how long its messages are kept; older messages, their attachments and related notes are deleted automatically every night. Each workspace can also set how long its calls, recordings and voicemail are kept; older ones are deleted automatically. Signed-out sessions, expired sign-in links and push tokens for devices that are no longer signed in are cleared on the same schedule. The log of texts from Sonaline's number is kept for 90 days. Your consent to account, security, fraud and support messages is kept until you turn it off, reply STOP, remove that number, or your account is deleted. A mobile number you verified stays on your account until you remove it, which you can do at any time in Settings. When a workspace closes its account, its data is deleted: its records at once and its call history within a day, with stored files and encrypted backups following within about 30 days.

Security

All connections are encrypted. Passwords are stored only as hashes, secrets such as connected-account tokens are stored encrypted, and staff can protect their accounts with passkeys or an authenticator app.

Your choices

Children

Sonaline is a service for businesses and is not directed at children under 13.

Changes

When this policy changes, we will update the date at the top of this page, and tell workspaces of any significant change before it takes effect.
