Upper Tail Software LLC
Terms of use — Trade Secret Ledger
Last updated August 28, 2026.
1. What this is, and your license.
Trade Secret Ledger is software for keeping a business record. Upper Tail Software LLC ("Upper Tail") grants you a limited, non-transferable license to use the app on any Apple-branded products that you own or control, as permitted by the Usage Rules set out in the Apple Media Services Terms and Conditions. The app may also be accessed, acquired and used by other accounts associated with you through Family Sharing, volume purchasing or Legacy Contacts, where Apple makes those available.
2. Not legal advice.
The app is not legal advice. Using it does not create an attorney-client relationship, and does not create a professional relationship of any kind, between you and Upper Tail or between you and any person associated with it. It does not tell you whether anything you record is a trade secret, whether it is adequately protected, or what to do about it.
3. Your records are yours, and keeping them is up to you.
You own what you enter. You are responsible for what you enter, for keeping it accurate, and for keeping your own copies.
We hold no copy of your register and cannot recover it. The app stores your register on your iPhone only. There is no server and no account, so if the device is lost, damaged, wiped or replaced, the register goes with it and nobody — including us — can restore it for you.
Backups are your choice and are off until you make it. The app does not include your register in your device's backups unless you switch that on in Settings. The app cannot create a backup itself; it can only decide whether the register takes part in a backup you have already set up on your iPhone. If you have no backup set up there, switching it on changes nothing.
If you do switch it on, your register is included in whatever backup you have configured — Apple's iCloud backup or a backup to your own computer — and from that point it is held and handled by Apple or by your computer under their terms, not ours. We have no access to those backups and no ability to retrieve anything from them.
The way to keep your own copy is to export. The app exports your whole register as PDF, CSV and JSON files that you choose where to send. We recommend doing that regularly, and we cannot do it for you.
4. What the app does not do.
It does not verify anything you enter. It does not monitor your business. It does not tell you when something has changed in the world outside your own entries. The checks it shows you are arithmetic on your own records and nothing more.
5. Free period and subscription.
When you first open your own register you get 14 days of full access at no charge. No payment method is needed and nothing is charged. The free period is counted by the app on your device and is not a subscription.
After that, full access is by auto-renewing annual subscription at $199 per year, charged to your Apple Account when you choose to subscribe. It renews automatically unless canceled at least 24 hours before the end of the current period. Manage or cancel it in your Apple Account settings. If you do not subscribe, your register stays readable and exportable and you cannot add or change entries.
6. No warranty.
The app is provided as is. Upper Tail does not warrant that it is error-free or that it will meet your requirements. To the extent any warranty cannot be disclaimed, Upper Tail, and not Apple, is solely responsible for it.
If the app fails to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price of the app to you. To the maximum extent permitted by law, Apple has no other warranty obligation of any kind with respect to the app. Any other claims, losses, liabilities, damages, costs or expenses attributable to a failure to conform to a warranty are Upper Tail's sole responsibility.
7. Limitation of liability.
To the fullest extent permitted by law:
(a) Upper Tail is not liable for any indirect, incidental, special, consequential or punitive damages, or for any lost profits, lost revenue, lost business, or loss of or damage to data, arising out of or relating to the app or these terms, whether in contract, tort or otherwise, and whether or not Upper Tail has been advised that such damages are possible.
(b) Upper Tail's total liability for all claims arising out of or relating to the app or these terms will not exceed the amounts you paid to Upper Tail in the twelve months before the event giving rise to the claim.
(c) Nothing in these terms excludes or limits liability that cannot be excluded or limited under applicable law.
(d) These limits apply even if a remedy stated in these terms fails of its essential purpose.
(e) Any claim arising out of or relating to the app or these terms must be brought within one year of the event giving rise to it, except where a longer period is required by law.
8. How this license ends.
You may end it at any time by deleting the app from your devices.
If you materially breach these terms, your license ends and you must stop using the app and remove it. Be clear about what that means in practice: the app has no server and no remote control, so the end of your license is a legal consequence and not something Upper Tail can bring about by switching anything off.
Letting your subscription lapse is not a breach and does not end your license. If you stop paying, your register stays readable and fully exportable, and it stays that way for as long as you keep the app. Only the ability to add and change entries stops.
If Upper Tail stops publishing the app, stops supporting it, or ceases business, a copy already installed continues to work as it is — there is nothing to switch off. Upper Tail does not undertake to provide updates, and an app that stops being updated may eventually cease to work on a future version of iOS.
9. Governing law and where disputes are heard.
These terms are governed by the laws of the State of Oregon, without regard to its conflict-of-laws rules. You and Upper Tail agree that the state and federal courts sitting in Jackson County, Oregon have exclusive jurisdiction over any dispute arising out of or relating to the app or these terms.
Nothing in this clause deprives you of the protection of any mandatory law of the place where you live, or of any right you have under that law to bring proceedings there.
10. Changes to these terms.
If these terms change, the new version will be published with a new date and will be the version supplied with the app from that point.
A change binds you when you accept it — for a new customer, when you first set up your own register; for an existing customer, on the first launch after an app update that carries the new version, when the app asks you to acknowledge it. The app records which version you acknowledged and when.
Because the app has no server, Upper Tail cannot deliver revised terms to a copy that is never updated. If you do not update the app, the version you acknowledged continues to govern your use of that copy.
11. Severability.
If any provision of these terms is held invalid, illegal or unenforceable, it will be modified to the minimum extent necessary to make it enforceable, or severed if it cannot be, and the remainder of these terms will continue in full force. This clause does not apply to clause 13, which is required by Apple.
12. Contact.

13. Apple.
The following apply because the app is distributed through the App Store.
(a) This agreement is with us, not Apple. You and Upper Tail acknowledge that these terms are concluded between you and Upper Tail only, and not with Apple, and that Upper Tail, not Apple, is solely responsible for the app and its content. Nothing in these terms provides usage rules for the app that conflict with the Apple Media Services Terms and Conditions.
(b) Maintenance and support. Upper Tail is solely responsible for providing any maintenance and support services for the app, as specified in these terms or as required by law. You and Upper Tail acknowledge that Apple has no obligation whatsoever to furnish any maintenance and support services for the app.
(c) Product claims. You and Upper Tail acknowledge that Upper Tail, not Apple, is responsible for addressing any claims by you or any third party relating to the app or your possession or use of it, including but not limited to (i) product liability claims; (ii) any claim that the app fails to conform to any applicable legal or regulatory requirement; and (iii) claims arising under consumer protection, privacy or similar legislation. These terms do not limit Upper Tail's liability to you beyond what is permitted by applicable law.
(d) Intellectual property. You and Upper Tail acknowledge that, in the event of any third-party claim that the app, or your possession and use of it, infringes that third party's intellectual property rights, Upper Tail, not Apple, will be solely responsible for the investigation, defense, settlement and discharge of that claim.
(e) Legal compliance. You represent and warrant that (i) you are not located in a region that is subject to a U.S. Government embargo, or that has been designated by the U.S. Government as a "terrorist supporting" region; and (ii) you are not listed on any U.S. Government list of prohibited or restricted parties.
(f) Third-party terms. You must comply with any applicable third-party terms of agreement when using the app — for example, the terms of your wireless data service agreement.
(g) Apple as third-party beneficiary. You and Upper Tail acknowledge and agree that Apple, and Apple's subsidiaries, are third-party beneficiaries of these terms, and that upon your acceptance of these terms Apple will have the right — and will be deemed to have accepted the right — to enforce these terms against you as a third-party beneficiary of them.
