These terms are an agreement between you and Rivet. They cover how you can use the app, the free trial and the purchase, AI features, and the limits of what Rivet can do.
Rivet (“Rivet,” “we,” “us”) is provided by James Whelan. By downloading or using the app, you agree to these Terms of Use and to our Privacy Policy. If you don’t agree, don’t use Rivet.
1. Who can use Rivet
You must be at least 16 years old, or the minimum age of digital consent in your country, to use Rivet. You’re responsible for activity under your account.
2. Your licence to use the app
We grant you a personal, non-exclusive, non-transferable, revocable licence to use Rivet on Apple devices you own or control, for your own use. Rivet is licensed, not sold. Your use is also subject to Apple’s standard Licensed Application End User License Agreement; where these terms and Apple’s EULA conflict, Apple’s EULA governs for the app licence.
3. Your account
You can use Rivet without an account. Some features, such as Claude, need you to sign in with Sign in with Apple or Google; the Privacy Policy lists them. Keep your sign-in secure — you’re responsible for what happens through your account.
4. The free trial and the purchase
Rivet is free to download. To use it, start the free trial in the app or buy Rivet. The trial is free and gives you all of Rivet for 3 days, ending 72 hours after it starts. Trials started before 18 October 2026 keep the length they were offered. Rivet is one purchase, paid once through the App Store, with no subscription. It covers Rivet on iPhone, iPad and Mac, and where the App Store offers it, your family can use it through Family Sharing. The price is shown in the app before you buy.
When the trial ends, and whenever you have neither a trial nor a purchase in force, Rivet locks until you buy it: you can still restore a purchase and export your data. Restoring a purchase, syncing, exporting your data and deleting your account never need a purchase.
Payment is charged to your Apple Account when you confirm the purchase. Purchases and refunds are handled by Apple under its terms; you can ask Apple for a refund at reportaproblem.apple.com. If you bought one of Rivet’s earlier monthly, yearly or lifetime plans, it keeps working on the terms you bought it under. Those plans are no longer sold, and you manage or cancel an earlier subscription in your Apple Account settings.
5. AI features and your calendar
Rivet uses AI to understand what you type or say in Ask and to suggest plans. It works on your device and, if you allow Claude by Anthropic, also uses Claude, as do meeting write-ups, Rewind stories, Saved’s summaries and reading picks, project plans and the Fitness coach (the Privacy Policy says what each sends). AI can be wrong or incomplete, so before Ask changes your calendar, reminders or to-dos it shows you what it will do and waits for you to tap Add, Apply or Use. Always review suggestions before you confirm them. You’re responsible for the changes you approve.
6. Your data is your responsibility
Your timeline is stored on your device and synced through your own iCloud; Rivet’s server doesn’t keep a copy. We recommend keeping your own device backups (for example, via your device’s backup feature). We aren’t responsible for data lost due to device failure, deletion, or your removal of the app.
7. Health and medication reminders
Rivet can display health information and medication reminders that you choose to set up. Rivet is not a medical device and does not provide medical advice. Don’t rely on it for safety-critical health or medication timing — use a dedicated tool and your healthcare provider for that.
8. Acceptable use
Don’t misuse Rivet. In particular, don’t reverse-engineer, decompile, or tamper with the app; don’t scrape, resell, or commercially exploit it; don’t attempt to break its security or interfere with others; and don’t use it to break the law or violate the terms of any connected service (such as Google or Apple).
9. Intellectual property
Rivet, including its software, design, content, and brand, is owned by us and protected by law. Your content remains yours. These terms don’t give you any rights in our intellectual property beyond the licence above.
10. Third-party services
Rivet works with services run by others — including Apple, Google, Anthropic, Trakt, TMDB, OMDb, Open Library and YMove. Your use of those services is governed by their own terms and privacy policies, and we’re not responsible for them. Rivet’s use of Google data follows the Google API Services User Data Policy.
11. Disclaimers
Rivet is provided “as is” and “as available,” without warranties of any kind, whether express or implied, to the fullest extent permitted by law. We don’t warrant that the app will be uninterrupted, error-free, or that it will sync, parse, or schedule perfectly in every case.
12. Limitation of liability
To the fullest extent permitted by law, Rivet and James Whelan will not be liable for any indirect, incidental, special, consequential, or punitive damages, or for any loss of data, profits, or goodwill, including any missed event, reminder, or deadline, arising from your use of the app. Nothing in these terms limits liability that cannot be limited by law.
13. Indemnity
You agree to indemnify and hold us harmless from claims arising out of your misuse of Rivet, your content, or your breach of these terms.
14. Termination
You can stop using Rivet at any time. We may suspend or end your access if you break these terms or if we stop offering the service.
15. Changes to these terms
We may update these terms as Rivet changes. We’ll update the date above and, for material changes, notify you in the app. Continuing to use Rivet after a change means you accept the updated terms.
16. Governing law
These terms are governed by the laws of Ireland, without regard to conflict-of-law rules, and the courts of Ireland will have exclusive jurisdiction, except where mandatory consumer-protection laws in your country of residence say otherwise.
