Terms of Use

Effective November 10, 2026

These terms cover the Spring Agent app for iPhone and iPad (“the app”), made by kezhenxu94 (“we”, “us”). The app is licensed to you under Apple's Licensed Application End User License Agreement; these terms add to it. By using the app you agree to both.

What the app is

The app is a client for a Spring Agent server that you run, or that someone runs for you. We don't provide that server, the AI models it uses, or the services it connects to, and we aren't responsible for them. Their own terms apply.

Your agent's actions

Your agent is an AI system. Its answers can be wrong, incomplete or out of date, and you should check anything that matters before relying on it. When you let your agent act on this phone — set an alarm, add an event, log Health data, prepare a message — you decide which tools it may use and how freely, and you are responsible for the actions you allow. Drafts of mail and messages are opened for you to review; nothing is sent without you.

The app is not a medical device. Health data it reads or logs is not medical advice.

Spring Agent Pro

Pro unlocks actions on this phone and more than three connectors. It is offered as:

• Monthly and Yearly auto-renewing subscriptions. Payment is charged to your Apple Account when you confirm the purchase. A subscription renews automatically at the same price and period unless you cancel it at least 24 hours before the end of the current period; your account is charged for renewal within the 24 hours before the period ends. Manage or cancel in Settings › Apple Account › Subscriptions.
• A free trial, where offered, for new subscribers only. If you don't cancel at least 24 hours before the trial ends, the subscription begins and is charged. Any unused part of a trial is forfeited when you buy a subscription.

Prices are shown in the app before you buy. Purchases are made through and refunded by Apple, under Apple's terms; to ask for a refund, visit reportaproblem.apple.com. Use “Restore purchases” in the app to bring Pro to another device signed in to the same Apple Account.

Acceptable use

Don't use the app to break the law, to infringe others' rights, or to access servers, accounts or data you aren't allowed to.

Changes and availability

We may change, add or remove features. If these terms change, the new version will be posted here with a new effective date; continuing to use the app means you accept it.

No warranty

To the extent the law allows, the app is provided “as is”, without warranties of any kind, and we are not liable for indirect or consequential losses, or for losses caused by your agent server, AI models, connected services, or actions you allowed your agent to take. Nothing in these terms limits rights you have under consumer law that cannot be limited.
