Terms of service

1. Who can use kaylin

kaylin is for businesses in the United States. You must be at least 18 and able to enter a contract. Don't use kaylin as a consumer for personal, family or household purposes. kaylin's phone numbers are US numbers, and it calls and texts US numbers only.

2. Your account and workspace

Keep your sign-in details safe and tell us at support@kaylin.io if you think someone else has used your account. You're responsible for what happens in your workspace, including what the members you invite do. Owners and admins decide who joins and what each member can do. Give us accurate business details: we use them to register your phone numbers and texting with the phone carriers.

3. Plans, free trial and automatic renewal

Plans

Each plan includes a monthly allowance of credits, a number of phone numbers and a number of people. The plans, prices and what each includes are shown on our pricing page and at checkout before you pay. Prices don't include taxes, which we add where the law requires.

Free trial

You pick a plan when you start the free trial and give us a payment card. The trial lasts 7 days (14 days if you sign up through a referral link) and includes a limited number of credits and one phone number; texting turns on after your first payment. The trial ends 7 days (14 with a referral link) after you start it, at the same time of day, and that's when your card is charged. Unless you cancel before the trial ends, your card is charged the plan's price when the trial ends, and your plan then renews automatically as described below. We send you a reminder, by text or email as you choose, the day before the trial ends. You won't be charged if you cancel before the trial ends.

Automatic renewal

Monthly plans renew every month, and yearly plans every year, at the price then in effect, and your card is charged at the start of each period until you cancel. There's no minimum term. We tell you at checkout the amount and how often you'll be charged, and email you a confirmation that includes how to cancel. Before a yearly plan renews we remind you by email at least 15 days ahead.

Yearly plans

Yearly plans are paid for the year ahead. If you cancel a yearly plan, it stays active until the end of the year you've paid for and isn't charged again. We don't refund the months left, except where the law requires it.

How to cancel

Cancel any time in the app under Settings → Billing, in a few clicks, without calling anyone. You can also email support@kaylin.io. Canceling stops future charges; your plan stays active until the end of the period you've paid for. Then the workspace stops answering calls.

Your data

Owners and admins can download a copy of your contacts, calls (summaries, transcripts, notes and links to recordings), texts with customers and bookings at any time, under Settings → Workspace → Download your data. Download it before your plan ends: a closed workspace's data is deleted within 30 days.

Your phone numbers

You can keep a number kaylin gave you by moving (porting) it to another phone provider. Start the move with the new provider before your plan ends, and email support@kaylin.io so we can give them what they need. Numbers that aren't moved are released 30 days after your plan ends and can't be gotten back. A number you forward to kaylin stays with your own provider.

When your credits run out

Calls to your numbers are always answered. We tell owners and admins when 80% and 100% of the month's credits are used.

• Extra usage off (the default): nothing is billed beyond your plan. kaylin takes messages instead (short calls of about 2 minutes), and calls out, autopilots and chat pause until your credits renew. Message-taking is included up to about 20% of your plan's monthly credits; after that, calls go to your forwarding number or to a plain voicemail, without AI.
• Extra usage on: an owner or admin turns it on and sets a monthly spending cap. Credits used beyond your plan are billed at the extra usage rate shown at checkout and on the Billing page, charged at the end of the month, and never more than your cap. When the cap is reached, kaylin takes messages and then voicemail, as above.

Unused credits don't carry over to the next month.

Referral credits

After your first payment you get a referral link in Settings → Billing. A business that signs up through it gets a 14-day free trial. When that business has made its second payment, you get account credit equal to one month of its plan's price, used toward your next bills; credit left over carries forward. Credit has no cash value, can't be transferred and ends when your account closes. You can earn up to 12 referral credits a year. Referring yourself, or a business you own or control or that uses the same payment card, doesn't count, and if the referred business's payment is refunded or charged back we take the credit back. Share your link yourself: kaylin doesn't text or call the people you refer. If you share it publicly, for example on social media, a website or in a review, say that you get credit when people sign up through it. We may change or end the program for future referrals with 30 days' notice; credit you've already earned stays.

Price changes and refunds

We'll tell you at least 30 days before a price change, which applies from your next renewal; you can cancel before then. Payments aren't refundable, including for partly used periods, except where the law requires a refund or we tell you otherwise in writing.

Payments

Card payments are processed by Stripe; your card number goes straight to Stripe and we never see or store it. If a payment fails we'll try again and let you know. If it's still unpaid 14 days later, we may pause your workspace until it's paid.

4. How you use kaylin

You control how kaylin answers, what it says, who it calls and texts, and what it records and keeps. You're responsible for using it lawfully, including:

• telling callers when calls are recorded or handled by AI, and getting any consent the law of your state or theirs requires;
• having the consent the law requires before you have kaylin call or text anyone, honoring opt-outs, and keeping to calling hours and do-not-call rules;
• having the right to give us every contact list and file you upload or import;
• checking what kaylin drafts or proposes before you approve it.

kaylin has settings that help you use it lawfully, like telling callers they're talking to AI, asking before recording, calling hours and stopping texts after an opt-out. Some are turned on and locked based on your business's state. They support lawful use; they don't guarantee it. The rules can depend on where you and the people you call or text are, the kind of call or text and how you use kaylin, and you stay responsible for following them.

The acceptable use policy lists what kaylin can't be used for. We may review use that's reported to us or looks unlawful.

5. AI makes mistakes; not for emergencies

kaylin uses AI to answer calls, write messages and summarize. It can misunderstand, leave things out or get things wrong, and it can't guarantee that every call is answered or every message delivered (phone networks, carriers and other services fail at times). kaylin doesn't give professional, legal, medical or financial advice. It isn't an emergency service: it doesn't connect to 911, and callers with an emergency should hang up and call 911.

6. Your data

Your business's data stays yours. You let us host and process it only to run kaylin for you, as the privacy policy describes. For your callers' and customers' information we act on your behalf and follow your instructions in the app. Connected accounts (email, calendar, bookkeeping and other apps) are used only for what you ask and the features you turn on, and you can disconnect them at any time. Our support team looks inside your workspace only if an owner turns on support access, only to read, and every look is logged.

For your account and billing, we decide how your information is used, as the privacy policy says. For the information kaylin handles for your business (your callers', customers' and contacts' details, and your calls, texts, emails and files), we work for you: we use it only to run kaylin for you, follow your instructions in the app, keep it confidential, protect it with reasonable security and delete it when you delete it or your workspace closes. You're responsible for having the right to give it to us and for telling your customers how you use it.

7. Phone numbers and texting registration

Phone numbers are provided through our phone carrier partner and are assigned to your workspace while your plan is active. To send texts, the phone carriers require your business to be registered; you authorize us to submit your business details for that registration, and you confirm they're accurate. Carriers may block, filter or limit texts and calls.

Phone number and texting fees. Your plan includes your kaylin phone numbers and their monthly costs, and the carriers' monthly fee for your texting registration. If you want to text customers, the carriers charge a one-time fee to register your business. On monthly plans we pass it on at cost, and the amount is shown before you send the registration in. Yearly plans include it.

kaylin text messages. kaylin sends texts from kaylin numbers: alerts to team members who tick Text me kaylin alerts, and, for each business, texts to its own customers who texted the business first or said yes on a call when kaylin asked "Is it OK if I text you at this number?": replies, booking confirmations and reminders, and follow-ups about what they asked for. kaylin doesn't send marketing texts. The first text from a number says what the texts are for and how to stop them. How often texts come depends on how you use kaylin. Message and data rates may apply. Reply HELP for help, or email support@kaylin.io. Reply STOP to stop texts from that number; you'll get one text confirming it. Carriers aren't liable for delayed or undelivered messages.

8. Other services

kaylin works with services like Twilio, Vapi, Deepgram, ElevenLabs, Anthropic, Stripe, Google, Microsoft, Zoho, Intuit (QuickBooks) and Composio. Their terms apply to your use of their services, and we aren't responsible for their outages or changes.

9. Our property and your feedback

kaylin, its software, voices, designs and content belong to us or our licensors. You get the right to use kaylin for your business while your plan is active; you may not copy, resell or reverse-engineer it. If you send us ideas or feedback, we may use them without owing you anything.

10. Indemnification

You will defend, indemnify and hold harmless YAH BRANDS, LLC and its owners, officers, employees and contractors from every claim, demand, fine, penalty, loss, damage, cost and expense (including reasonable attorneys' fees) that comes from or relates to:

• how you, your members or anyone using your workspace use kaylin;
• calls, texts, emails and recordings made, sent or kept through your workspace, including claims under the Telephone Consumer Protection Act, call-recording and wiretap laws, telemarketing and do-not-call rules, and privacy laws;
• the content, contact lists, files and instructions you give kaylin;
• your breach of these terms or the acceptable use policy, or of any law;
• your dealings with your own customers, callers and staff.

We'll tell you promptly about a claim, let you control its defense with a lawyer we reasonably accept, and help at your cost. You may not settle a claim in a way that admits fault for us or binds us without our written consent.

11. No warranty

kaylin is provided "as is" and "as available". As far as the law allows, we disclaim all warranties, express or implied, including merchantability, fitness for a particular purpose, accuracy and non-infringement, and we don't promise kaylin will be uninterrupted or error-free.

12. Limits on our liability

As far as the law allows, we aren't liable for indirect, incidental, special, consequential or punitive damages, or for missed calls, lost business, lost profits, lost data or harm to reputation, even if we were told they might happen. Our total liability for all claims about kaylin is limited to the greater of what you paid us in the 12 months before the claim and $100. These limits don't reduce what you owe us, or your duties under section 10.

13. Suspension and ending

You can stop using kaylin and cancel at any time (section 3). We may suspend or close a workspace that doesn't pay, breaks these terms or the acceptable use policy, or puts others at risk; we'll tell you why unless the law or safety stops us. After a workspace closes, we delete its data within 30 days, except what the law requires us to keep; copies in backups are overwritten as backups roll over. Sections 6 and 9 to 15 continue after these terms end.

14. Disputes

If there's a problem, email support@kaylin.io first and we'll try to sort it out within 30 days. These terms are governed by the laws of Wyoming, without regard to conflict-of-law rules, and any lawsuit must be brought only in the state or federal courts in Wyoming, which both of us agree to. Claims must be brought individually, not as part of a class or representative action.

15. General

These terms, the policies they link to and anything you accept at checkout are the whole agreement between us about kaylin. If a part can't be enforced, the rest still applies. You may not transfer these terms without our consent; we may transfer them with our business. Neither of us is responsible for delays caused by events beyond reasonable control. Not enforcing a right isn't a waiver of it.

16. Changes

We may update these terms. We'll change the date above and, for changes that matter, tell you in the app or by email at least 30 days before they take effect. Using kaylin after that means you accept the new terms; if you don't, you can cancel.
