Terms of service

Last updated October 29, 2026

These terms are between you and Modini LLC, doing business as Testera Labs ("we"), the maker of Undertone, a macOS app. By downloading or using Undertone you agree to them.

Using Undertone

Undertone runs on your Mac. It transcribes calls on your device, explains terms and helps you prepare and follow up, using the AI and the work tools you choose to connect. You're responsible for using it lawfully, including telling or getting consent from the people on a call where the law requires it before you transcribe it.

Answers, hints and documents are written by AI and can be wrong. Check anything important before you rely on it.

Your content

Your meetings, transcripts, notes and files stay on your Mac and remain yours. We don't receive them, except as described in our privacy notice when you use Undertone's AI credits.

Undertone Pro

Undertone Pro is a subscription, billed monthly or yearly, that adds features listed on the Pro page and a monthly allowance of AI credits. Credits are for use in Undertone, have no cash value and don't carry over past the end of your subscription.

Our order process is conducted by our online reseller Paddle.com. Paddle.com is the Merchant of Record for all our orders. Paddle provides all customer service inquiries and handles returns.

Subscriptions renew automatically until you cancel. You can cancel at any time from the link in your receipt email or by writing to us; Pro keeps working until the end of the period you paid for. Refunds are covered by our refund policy.

Your license key is for your own use. Don't share or resell it.

Free credits and fair use

Free and included AI credits are offered for normal use of Undertone. We may limit or end credits that are abused, for example through automated or shared accounts.

Changes and availability

We improve Undertone often and may change or remove features. We'll give notice of material changes to these terms on this page. Undertone is provided "as is", without warranties, and to the extent the law allows, our liability is limited to the amount you paid us in the 12 months before a claim.
