Terms of Use
1. Agreement
These Terms of Use ("Terms") are an agreement between you and the independent developer who runs Letter Sense ("we", "us") for the Letter Sense app and related services (the "App"). By creating an account or using the App you accept these Terms and our Privacy Policy. If you do not accept them, do not use the App.
The App is distributed through Apple's App Store (and, during testing, through TestFlight). Apple's Licensed Application End User License Agreement also applies. If it conflicts with these Terms, Apple's agreement prevails for matters it covers.
2. Who may use the App
You must be at least 18 years old and able to enter into a binding contract. The App is intended for use in the United States.
3. What the App does
You photograph or select pages of a letter, SMS or email screenshot. The App sends the images to an AI service to read them, and shows you a "card" in your language: what the document appears to be, who sent it, whether action seems to be required, a deadline and an amount if they are written or can be calculated from the document, short quotes from the document, general steps, and warning signs. The App can set reminders on your phone, keep an archive with search, and send summaries and urgent alerts by email to trusted people you add.
4. What the App is not
The App only explains what a document says. It is not:
- a lawyer, law firm or legal service. It does not give legal advice or prepare legal documents or replies;
- a tax adviser, accountant, financial or investment adviser, credit or debt counselor, doctor, immigration adviser, or insurance adjuster or public adjuster. It does not give tax, financial, credit, medical, immigration or insurance-claim advice;
- protection against fraud. A "possible scam" or "looks like a known type of letter" label is only a reading of the text. "Looks genuine" does not mean "safe";
- a way to pay bills. It does not store payment card or bank details;
- a mailbox connection. We cannot read your email or postal mail unless you photograph or select it;
- a representative. We do not contact senders, file anything, or act for you.
No professional relationship. Using the App does not create an attorney-client, tax-preparer, adviser or any other professional relationship between you and us.
No promised outcome. We do not promise any result with a sender, agency, insurer, creditor or court, and the App cannot prevent a penalty, a charge or a missed deadline.
Independent. Letter Sense is independent. It is not affiliated with, endorsed by, or acting for the IRS, USCIS, any other government agency, bank, insurer or any sender whose letters it reads. Names of senders appear only to describe the letters.
For letters in sensitive categories (for example court, tax penalties, immigration, insurance claims, debt collection, or any letter that mentions a lawyer), the App only says what the document is, the dates and amounts it states, and that you should show it to a qualified professional.
5. AI output may be wrong
Cards are produced automatically by AI. They can contain mistakes, omit information, or misread a photo. Before you rely on a card, check every date, amount and sender against the paper original. A deadline marked "calculated" or "unclear" must always be checked. You are responsible for the decisions you make and the actions you take or do not take. Never pay money, share a Social Security number, card number or password, or call a phone number from a suspicious message; use an official website or the number on an official statement or in your account.
6. Reminders
Reminders are notifications that your phone shows, based on dates found in your letters or entered by you. They depend on your phone's settings, battery, software and notification permissions, and may not appear. We do not guarantee that you will receive a reminder, that a deadline is correct, or that you will meet any deadline.
7. Your account and content
You sign in with Sign in with Apple. Keep your Apple ID secure. You remain the owner of your letters and photos ("Your Content"). You give us a limited license to store, process and display Your Content only to run the App for you, including sending it to our service providers such as the AI provider described in the Privacy Policy. You promise that you have the right to upload each letter (it is addressed to you, or to a person who allowed you to upload it) and that doing so does not break the law or anyone's rights. You can delete any letter or your account in the App.
8. Trusted people
You may add up to three trusted people by email. Add only people who agree to receive messages about your letters; you are responsible for that choice. A trusted person receives card summaries and alerts as described in the Privacy Policy, never photos. You can hide a letter from them and remove them at any time, and they can unsubscribe. A trusted person is not given legal authority, and the App is not a power of attorney or a guardianship arrangement. We do not verify who a trusted person is.
9. Acceptable use
Do not use the App to break the law; upload other people's documents without permission; upload content you have no right to; try to access other accounts; attack, overload or probe our systems; copy or reverse engineer the App except where the law allows; use automated means to send letters; or try to get around the App's limits or payment. We may apply reasonable limits, for example a daily limit on the number of letters.
10. Our rights
The App, its software, design and content (other than Your Content) belong to us or our licensors. Under Apple's Licensed Application End User License Agreement you get a personal, limited, non-transferable license to use the App on your Apple devices. Do not use our name or look to suggest that your product or service is ours or approved by us.
11. Subscriptions, free letters and testing
Some features need a paid subscription ("Letter Sense Plus"): reading more than the free number of letters (currently 3), and weekly summaries and urgent alerts to trusted people. Subscriptions are sold by Apple through the App Store. The price, length, any free trial, billing and renewal terms are shown on the subscription screen before you buy; a free trial is offered only with the yearly plan. Payment is charged to your Apple ID when you confirm the purchase (or when a free trial ends). Subscriptions renew automatically for the same period at the price shown, and your Apple ID is charged for the renewal within 24 hours before the end of the current period, unless you turn off auto-renewal at least 24 hours before that end. You manage and cancel subscriptions in your Apple ID settings; deleting the App or your account does not cancel a subscription. Refunds for App Store purchases are handled by Apple under its rules; we cannot issue them. You can ask Apple for a refund at reportaproblem.apple.com. If you reinstall the App or use a new device, use Restore Purchases to get your subscription back. Subscriptions are not shared through Apple Family Sharing. If your subscription ends, letters you already added, their deadlines and reminders stay available, but you cannot add more letters beyond the free limit. If a letter cannot be read, it does not use up one of your free letters; deleting a letter does not give a free letter back.
During beta testing we may give testers full access to the paid features for a limited time without a subscription. The App shows the end date. When it passes, the normal rules above apply.
12. Third-party services
The App relies on third parties, including Apple, an AI provider, and hosting and email providers. We are not responsible for their services or their availability. Apple is not responsible for the App or its support, and is not a party to these Terms except as stated in Apple's agreement.
13. Changes to the App and to these Terms
We may change, suspend or stop any part of the App. We may update these Terms; if the change is material we will tell you in the App or by email before it takes effect. If you keep using the App after the effective date, you accept the new Terms.
14. Ending your use
You can stop using the App at any time and delete your account in the App. We may suspend or end your access if you break these Terms or if needed to protect the App, other users or the law.
15. Disclaimer of warranties
The App and all cards are provided "as is" and "as available". To the fullest extent the law allows, we disclaim all warranties, including that the App will be accurate, complete, uninterrupted, error-free or fit for a particular purpose.
16. Limitation of liability
To the fullest extent the law allows, we are not liable for indirect, incidental, special, consequential or punitive damages, or for losses caused by missed deadlines, late fees, penalties, lost benefits or claims, or by decisions made in reliance on a card. Our total liability for any claim relating to the App is limited to the amount you paid for the App in the 12 months before the claim. Nothing in these Terms limits liability that cannot be limited by law.
17. Governing law
These Terms are governed by the laws of the State of Florida, United States, without regard to its conflict-of-laws rules. This does not take away consumer rights that you have under the law of the place where you live and that cannot be waived by contract.
18. General
These Terms and the documents they mention are the whole agreement between you and us about the App. If a part is found unenforceable, the rest stays in effect. If we do not enforce a right, we do not give it up. You may not transfer your rights without our consent; we may transfer ours with the business. If we provide these Terms in other languages and they differ, the English version prevails.
