Stinger — stingerprompt.com · Last revised: September 13, 2026
These Terms of Service govern your use of the Stinger application ("Stinger", "the app") and the website at stingerprompt.com (together, "the Services"), provided by First Light Holdings, LLC, a North Carolina limited liability company ("First Light Holdings", "we", "us").
By downloading Stinger, creating a trial, buying a licence, or using stingerprompt.com, you agree to be bound by these Terms. If you do not agree, do not use the Services.
We may revise these Terms from time to time. A revised version is posted on this page with a new date. Continuing to use the Services after that date means you accept the changes. If a change materially affects what your subscription costs or what it covers, we will also email the address on your licence.
Stinger is a Mac application that displays your script on screen, near or under your camera, while you speak. It runs entirely on your own Mac. Scripts and rehearsal recordings are stored as plain files on your Mac and are not uploaded by the app.
The website, stingerprompt.com, is where you learn about Stinger, buy a licence, download the app, and manage your licence through the customer portal. The app and the website are separate systems and are described separately in our Privacy Policy.
System requirements: macOS 15 (Sequoia) or later. The exact processor requirements for the version you install are stated on the download page.
We may change or discontinue features of the app or the website at any time. We do not commit to a fixed feature set beyond what is currently published.
Stinger does not have an in-app account or sign-in. Instead, when you buy Stinger you receive a licence key. The app sends a device name (which may include your Mac's name, and often a person's name as part of it) and a partial hardware identifier to our licence server to activate and periodically validate that key; it does not send your email address or any other device detail.
Separately, First Light Holdings operates a customer portal on stingerprompt.com where you sign in with the email address on your licence plus a one-time code sent to that address. The portal lets you see your licence, see and deactivate the Macs it is activated on, update your card, cancel renewal, and view receipts. We store the email address, licence key, plan, status, expiry, and the payment-profile reference, last four card digits and expiry, and billing address returned by our payment processor for the subscriptions billed through it.
You are responsible for keeping the email address on your licence accurate, since that address is how we reach you about your subscription, receipts, and any changes to these Terms that affect cost or coverage. All information you provide is subject to our Privacy Policy, which is incorporated by reference into these Terms.
We offer a free 7-day trial of Stinger. Starting a trial requires a valid, deliverable email address. The trial runs on one Mac, and we allow one trial per Mac and one trial per email address.
The trial covers everything in Stinger except Voice and Track scroll modes, Practice Partner and Voiceover. Scrolling runs in Auto mode; Ghost Check, Memorize, rehearsal recording, sections, take marks, the phone remote and the script editor are all included.
The trial runs for 7 days exactly from the moment it is issued. On day 7 the app stops working, with no grace period. There is no charge to start or end a trial. Scripts and recordings you made during the trial remain on your Mac after the trial ends.
You may not use multiple email addresses, multiple Macs, or any other method to obtain more than one trial for yourself.
When you buy Stinger, we grant you a non-exclusive, non-transferable licence to install and use the app, subject to these Terms. Each licence key works on two Macs at a time.
To use the app on a third Mac, deactivate one of your existing two from within the app or from the customer portal, which frees that seat, then activate on the new Mac.
You may not share a licence key beyond your own two Macs, resell a licence key, or circumvent the activation system.
The app periodically checks your licence with our server. If it cannot reach the server, it keeps working for 14 days on the last successful check before it asks you to reconnect.
Stinger is available as a paid subscription. Prices are shown in USD on stingerprompt.com and sales tax is calculated at checkout. By subscribing, you authorize our payment processor to charge your payment method for the plan you select.
Subscriptions renew automatically at the end of each billing period at the then-current rate unless you cancel first. You can cancel at any time from the customer portal; your licence stays active until the end of the period you already paid for, and then the app stops working as described below.
If a renewal charge is declined, we retry it. If it is still unpaid after 14 days, your subscription is canceled. If your subscription has ended, the app keeps working for three days after the expiry date — enough time for a renewal payment that is still processing — and then stops. A lifetime licence, if you hold one, carries no expiry date and does not lapse.
Stinger Premier adds Practice Partner and Voiceover to Stinger, at the prices shown on stingerprompt.com, billed monthly or yearly. Each billing month includes 60 practice minutes and 60 voiceover minutes, on monthly and annual plans alike.
You can buy more practice minutes, 30 at a time, at the price shown in the app or on the Site. Purchased minutes do not expire, are used after the month's included minutes, and stay on your licence if you cancel Premier and later return to it.
If a problem on our side cuts a Practice Partner or Voiceover session short, contact hello@stingerprompt.com and we will look at restoring the minutes it used.
Subscription fees and minute purchases are non-refundable. The free 7-day trial is there so you can try Stinger before you pay. If something is not working for you, contact hello@stingerprompt.com and we will help you through it.
The customer portal at stingerprompt.com/license lets you sign in with your email address and a one-time code sent to that address. From the portal you can see your licence, see and deactivate the Macs on it, update your payment method, cancel or resume renewal, and view your receipts.
There is no in-app account or sign-in for Stinger itself. Your licence key, and the separate customer portal, are how you manage your purchase.
You may use Stinger for your own scripts and your own recordings. You are responsible for the content of anything you write, read, or record with it.
You may not reverse-engineer, decompile, or attempt to extract the source code of the app, except to the extent a law gives you the right to do so. You may not redistribute, resell, or sublicense the app, or use it to build a competing product.
You may not attempt to bypass, disable, or interfere with the licence-activation system, the trial limits, or the update mechanism.
You may not use the Services for any unlawful purpose, or in a way that interferes with our servers or with other customers' use of the Services.
Stinger and stingerprompt.com rely on a small number of third-party providers to work: our payment processor (Authorize.Net) for billing, an infrastructure provider for the database and storage behind the licence server and portal, a hosting provider for the website and portal, a transactional email provider for receipts and account email, and Google Analytics on the marketing pages of the website (not inside the app). If you enable the optional KBD script sync feature in Settings, the app reads scripts over a connection you configure yourself with a token you provide. If you enable the optional phone remote, it serves a control page to other devices on your own Wi-Fi network; nothing about that feature reaches the internet.
Stinger Premier's Voiceover and Practice Partner send script text or live microphone audio to a third-party speech-recognition and speech-synthesis provider while you use them. We do not name that provider publicly. If you turn on iCloud script sync, your scripts are stored in your own iCloud Drive, which Apple provides under its own terms.
Your interactions with any of these third parties, including our payment processor, are governed by that provider's own terms, and First Light Holdings does not control and is not responsible for their availability, accuracy, or conduct.
Stinger, its source code, its design, and the Stinger name and mark are the property of First Light Holdings, LLC and are protected by applicable intellectual property laws. Buying a licence gives you the right to use the app under these Terms; it does not transfer any ownership or other rights in it to you.
Scripts you write and recordings you make in Stinger are yours. We claim no ownership over them.
Stinger is signed with an Apple Developer ID certificate and notarized by Apple, which means Apple has checked it for known malware signatures before it runs on your Mac; this is not an endorsement of the app by Apple. Stinger is not distributed through the Mac App Store. Mac and macOS are trademarks of Apple Inc., registered in the U.S. and other countries.
THE SERVICES ARE PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, OR NON-INFRINGEMENT.
WE DO NOT WARRANT THAT STINGER WILL BE UNINTERRUPTED, ERROR-FREE, OR COMPATIBLE WITH EVERY SCREEN-CAPTURE OR VIDEO-CONFERENCING TOOL. STINGER ASKS macOS TO EXCLUDE ITS WINDOW FROM SCREEN CAPTURE; WHETHER A GIVEN THIRD-PARTY APPLICATION HONORS THAT REQUEST IS OUTSIDE OUR CONTROL, AND WE MAKE NO GUARANTEE ABOUT ANY SPECIFIC APPLICATION.
WE DO NOT WARRANT THAT TRACK MODE OR VOICE MODE WILL ACCURATELY FOLLOW YOUR SPEECH IN EVERY ENVIRONMENT. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OF CERTAIN WARRANTIES, SO SOME OF THE ABOVE LIMITATIONS MAY NOT APPLY TO YOU.
TO THE EXTENT PERMITTED BY LAW, FIRST LIGHT HOLDINGS, LLC WILL NOT BE LIABLE FOR ANY SPECIAL, PUNITIVE, INCIDENTAL, INDIRECT, OR CONSEQUENTIAL DAMAGES ARISING FROM YOUR USE OF THE SERVICES, INCLUDING LOSS OF DATA, LOST RECORDINGS, OR LOST BUSINESS, EVEN IF WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
WHERE LIABILITY CANNOT BE EXCLUDED, OUR TOTAL LIABILITY TO YOU FOR ANY CLAIM RELATING TO THE SERVICES IS LIMITED TO THE AMOUNT YOU PAID US IN THE TWELVE (12) MONTHS BEFORE THE CLAIM AROSE. SOME JURISDICTIONS DO NOT ALLOW THIS LIMITATION, SO IT MAY NOT APPLY TO YOU.
You agree to defend, indemnify, and hold harmless First Light Holdings, LLC, its officers, and its employees from claims and expenses, including reasonable attorneys' fees, arising from your misuse of the Services, the content of your scripts or recordings, or your violation of these Terms or applicable law.
You are responsible for the confidentiality of your licence key and for keeping the email address on your licence and in the customer portal secure, since that address is how you sign in to the portal and how we reach you.
Each licence key may be activated on two Macs. If you replace, wipe, or sell a Mac, deactivate it first from the app or from the customer portal so the seat is released; deactivating removes that Mac's activation record. If a Mac was never deactivated, you can remove it from your licence in the customer portal at any time.
Secrets stored by the app on your Mac — such as a KBD script-sync token, if you turn that feature on — are kept in a private file with restricted permissions, separate from your scripts. Scripts, recordings, and take-mark files stay on your Mac and are never uploaded as part of licensing, activation, or updates; if you turn on iCloud script sync, your scripts are also kept in your own iCloud Drive under your Apple Account.
From time to time we may offer promotional pricing, such as an introductory price for a limited number of buyers or a limited period. Any promotional offer is subject to whatever terms are stated for it at the time. As of this writing, no promotional or founding-member pricing is published on stingerprompt.com.
Both parties agree not to disparage the other in any manner likely to harm the other's business or personal reputation, provided that both parties will respond accurately and fully to any question, inquiry, or legal process.
We may suspend or terminate your licence if you materially breach these Terms, including by sharing or reselling a licence key, attempting to bypass activation limits, or abusing the trial.
You may stop using the Services and cancel your subscription at any time from the customer portal. Cancelling stops future renewals; fees already charged are non-refundable, as Section 6 says.
These Terms are governed by the laws of the State of North Carolina, without regard to its conflict-of-laws principles. Both parties consent to the exclusive jurisdiction and venue of the courts located in North Carolina for any dispute arising under this Agreement.
Both First Light Holdings and you waive the right to a trial by jury. Any dispute must be brought in an individual capacity and not as part of a class action or representative proceeding.
These Terms, together with our Privacy Policy, are the entire agreement between you and First Light Holdings, LLC regarding the Services, and supersede any prior discussions or agreements on the subject.
If any provision of these Terms is held invalid or unenforceable, that provision will be limited or removed to the minimum extent necessary, and the remaining provisions will stay in full effect.
Sections of this Agreement that by their nature should survive termination of your licence or these Terms will survive, including, without limitation, ownership provisions, warranty disclaimers, indemnification, limitation of liability, governing law, and intellectual property sections.
Our failure to enforce any provision of these Terms is not a waiver of that provision or of our right to enforce it later.
Neither party will directly or indirectly offer or accept any improper payment, gift, or benefit in connection with this Agreement, other than ordinary, inexpensive business courtesies. A breach of this section is a material breach of these Terms.
Prevailing-Party Fees: in any action to enforce these Terms, the prevailing party may recover its reasonable attorneys' fees and costs.
Limitation on Claims: any claim relating to these Terms or the Services must be brought within one (1) year after it arises, or it is waived.
Assignment: you may not assign these Terms without our written consent; we may assign them freely, including in connection with a merger, acquisition, or sale of our business.
Force Majeure: we are not liable for delay or failure to perform caused by events beyond our reasonable control, including internet or power outages, natural disasters, or failures of third-party providers we rely on.
Notices: notices under these Terms should be sent by email to hello@stingerprompt.com, or to First Light Holdings, LLC at 4030 Wake Forest Rd, Ste 349, Raleigh, NC 27609, USA.
