These Terms of Service ("Terms") govern your access to and use of the Kael applications on iPhone and Mac and any related services (collectively, the "Service"), provided by Kael ("Kael", "we", "us"). By installing, accessing, or using the Service, you agree to be bound by these Terms. If you do not agree, do not use the Service.
For any questions, email admin@trykael.com.
Kael is a focus-and-productivity tool that helps you block distracting apps and websites on your Mac and iPhone and asks you to justify each unblock request. Kael is not a medical, therapeutic, or clinical service. It is not a substitute for professional mental-health care, addiction treatment, or medical advice. If you are in crisis, please contact your local emergency number or a qualified professional.
You must be at least 13 years old to use Kael. If you are under 18, you represent that you have permission from a parent or legal guardian. You agree to provide accurate information when creating your account and to keep that information up to date.
If you choose to connect a Google account, Kael will request read-only OAuth scopes (calendar.readonly, gmail.readonly, openid, email). The Calendar scope is used to time blocking around your meetings and classes. The Gmail scope is used only on Kael Pro to read the subject, sender, snippet, and received timestamp of inbox messages received in the last 24 hours, every 30 minutes while the app is in use, in order to surface upcoming events and deadlines as "Suggested Tasks". Kael:
You can revoke access at any time at myaccount.google.com → Security → Third-party apps → Kael, or from in-app Settings → Calendar Settings. Revocation immediately ends all calendar and Gmail reads.
Kael's use of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.
You agree not to:
Violation of §4 may result in immediate termination and, where applicable, legal action.
When you submit reasons, schedule entries, or a display name, you grant us a worldwide, non-exclusive, royalty-free license solely to operate and improve the Service (e.g. running the AI judge, storing your history, showing you your own insights). You retain ownership of the content itself. You represent that you have the rights necessary to grant that license.
We may remove content that we reasonably believe violates these Terms.
Kael uses Anthropic's Claude API for three things: (1) judging your typed unblock reasons, (2) classifying your synced calendar entries as events vs deadlines (Kael Pro), and (3) extracting events/deadlines from recent Gmail subjects + snippets (Kael Pro). All AI output is advisory. We do not guarantee that the AI will always be accurate, consistent, or complete — Suggested Tasks may miss real items or surface things you would not have added; calendar categorization may mislabel an entry; reason judgments may approve or deny in ways you disagree with. You remain solely responsible for your own schedule, your own focus choices, and your own device usage. Always verify anything time-sensitive against the original calendar entry or email.
Kael's core features are free. Kael Pro is an optional auto-renewing subscription (monthly or yearly) that unlocks adaptive modes, the AI day planner, calendar sync, the Gmail scanner, and other Pro features. Pricing is shown in-app before purchase. Payment is charged to your Apple ID, and the subscription auto-renews unless cancelled at least 24 hours before the end of the current period. Manage or cancel anytime in your Apple ID Account Settings. One subscription covers Kael Pro on both Mac and iPhone for the same Apple ID (Universal Purchase).
We may add, modify, or remove features at any time. We will provide reasonable advance notice for material changes that adversely affect you in a significant way.
You may stop using Kael and delete your account at any time via Settings → Account → Delete account or by emailing us at admin@trykael.com. We may terminate or suspend the Service or your account for violation of these Terms, for risk to the Service or other users, or for legal reasons. Sections §§4–6 and §§10–14 survive termination.
THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, ERROR-FREE, OR SECURE. SOME JURISDICTIONS DO NOT ALLOW THESE DISCLAIMERS — IN THOSE JURISDICTIONS THEY APPLY ONLY TO THE MAXIMUM EXTENT PERMITTED BY LAW.
TO THE MAXIMUM EXTENT PERMITTED BY LAW, WE WILL NOT BE LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, REVENUES, DATA, OR FOCUS TIME, ARISING OUT OF OR RELATED TO YOUR USE OF THE SERVICE. OUR TOTAL LIABILITY FOR ANY CLAIM RELATING TO THE SERVICE WILL NOT EXCEED THE GREATER OF USD 50 OR THE AMOUNTS YOU HAVE PAID TO US IN THE 12 MONTHS PRECEDING THE CLAIM.
You agree to indemnify and hold us harmless from any claim arising from your violation of these Terms, your content, or your misuse of the Service.
These Terms are governed by applicable law, without regard to conflict of law principles. If your local law grants you mandatory consumer protections (e.g. EU consumer law), those protections apply regardless.
