Terms & Conditions

1. Agreement to Terms

By accessing and using Keystone, you agree to be bound by these Terms and Conditions and our Privacy Policy. If you disagree with any part of these terms, you may not access the application. If you download Keystone from the Apple App Store, Apple's standard Licensed Application End User License Agreement also applies.

2. What Keystone Is

Keystone is an AI self-reflection app. You save identity keys (such as your core values and goals) and talk to an AI in two modes: Affirm, which helps you see the evidence for who you already are, and Question, which asks you questions about your beliefs and decisions. Keystone is operated by Redder Media LLC.

3. AI-Generated Content

Keystone's replies are generated by artificial intelligence, not by a person. They can be wrong, incomplete, or out of date. They reflect what you have written and saved, not verified facts about you or the world, and the AI may misunderstand you.

AI replies are not professional, medical, psychological, legal, or financial advice. You are responsible for your own decisions, and you should not rely on Keystone as the only basis for any important decision. You are free to disagree with the AI, and nothing it says changes your keys unless you accept it.

4. Not Therapy, and Getting Help

Keystone is a self-reflection tool, not a substitute for therapy, medical care, or emergency services. It is not a crisis service, and we do not monitor conversations in real time. Plenty of people use Keystone to think through hard things, and that is welcome, but it cannot give you the support you may need in a crisis.

If you are thinking about harming yourself or someone else, or you might be in danger, please reach out to someone who can help right now. In the US, call or text 988 (Suicide & Crisis Lifeline) or text HOME to 741741 (Crisis Text Line). Elsewhere, findahelpline.com lists services by country. If you might be in immediate danger, call your local emergency number.

5. Eligibility

You must be at least 13 years old to use Keystone. If you are under the age of majority where you live, you may use Keystone only with the permission of a parent or guardian. By using Keystone, you confirm that you meet these requirements.

6. Use License

Permission is granted to use Keystone for personal, non-commercial purposes. This license does not include:

  • Modifying or copying the materials
  • Using the materials for commercial purposes
  • Attempting to reverse engineer any software contained in Keystone
  • Removing any copyright or proprietary notations

7. User Account

To use certain features of Keystone, you must register for an account. You agree to:

  • Provide accurate and complete information
  • Maintain the security of your account
  • Notify us immediately of any unauthorized use
  • Accept responsibility for all activities under your account

8. User Content

You retain all rights to the content you create within Keystone, including your keys and your messages. By using our service, you grant us a limited license to:

  • Store and process your content
  • Send your content to our service providers, including our AI provider, to generate replies and provide the service
  • Use your content to provide and improve our services and to generate personalized reminders and feedback

You are responsible for what you write. Please see our Privacy Policy for how your content is handled. Keystone, its software, design, and branding, and the AI personalities we provide belong to Redder Media LLC or its licensors.

9. Acceptable Use

You agree not to misuse Keystone. This includes:

  • Trying to bypass usage limits, security measures, or paywalls
  • Accessing or attempting to access other people's accounts or data
  • Using Keystone to harm, harass, or deceive others, or to break the law
  • Attempting to extract, copy, or reverse engineer the AI's instructions or our systems
  • Using automated means to access the service, other than through the app as provided

10. Subscriptions

Some features of Keystone require Keystone Pro, an auto-renewing subscription. The price and billing period are shown in the app before you subscribe. Payment is charged to your Apple ID account at confirmation of purchase. Your subscription renews automatically unless you cancel it at least 24 hours before the end of the current period, and your account will be charged for renewal within 24 hours before the end of the current period.

If we offer a free trial, it converts to a paid subscription at the end of the trial unless you cancel at least 24 hours before the trial ends. Any unused portion of a free trial is forfeited when you purchase a subscription.

You can manage or cancel your subscription in your iPhone's Settings, under your name, then Subscriptions. Subscriptions are billed and refunded by Apple, not by Keystone, so refund requests go through Apple. Deleting your Keystone account does not cancel an Apple subscription.

11. Promotional Offers and Referral Codes

A promotional code or free month gives access to Keystone Pro for the stated period and is limited to one per account unless we say otherwise. Codes have no cash value, cannot be sold or transferred, and may expire. We may revoke codes that were obtained through abuse or in bulk.

12. Third-Party Services

Keystone relies on third-party services, including Apple, Google, our AI provider, and others described in our Privacy Policy. We are not responsible for those services, and your use of them may be subject to their own terms. Links to third-party sites, such as our Discord community, are provided for convenience, and we are not responsible for what other members post there.

13. Ending Your Account

You can delete your account at any time from the app by opening Profile and choosing Delete Account. We may suspend or end your access if you break these terms or misuse the service. Sections that by their nature should survive termination, including the disclaimers, limitations, and governing law, will survive.

14. Disclaimer

Keystone is provided "as is" and "as available" without any warranties, express or implied, to the fullest extent permitted by law. We do not warrant that:

  • The service will be uninterrupted or error-free
  • The results obtained, including AI-generated replies, will be accurate, complete, or reliable
  • The service will help you reach any particular goal or outcome
  • The quality of the service will meet your expectations

15. Limitations

To the fullest extent permitted by law, in no event shall Redder Media LLC or its suppliers be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of data or profits, arising out of the use or inability to use our service, even if we have been notified of the possibility of such damages. Nothing in these terms limits liability that cannot be limited by law.

16. Modifications

We reserve the right to modify or discontinue, temporarily or permanently, Keystone or any features or portions thereof without prior notice. We shall not be liable for any modification, suspension, or discontinuance of the service. We may also update these terms from time to time. If we make a material change, we will post the new terms on this page, update the "Last Updated" date, and give notice in the app or by email. Continuing to use Keystone after a change means you accept the updated terms.

17. Governing Law

These Terms shall be governed by and construed in accordance with the laws of the United States and the state in which Redder Media LLC is organized, without regard to its conflict of law provisions.
