Effective and last updated: November 12, 2026. Version 1.

Terms of Use

These Terms describe the Big Cal service provided by Actually Good Ideas LLC. Please read them before using the service. Questions can be sent to privacy-bigcal@actuallygoodideas.com.

Agreement and separate choices

By using the Big Cal service after these Terms take effect, you agree to them. If you do not agree, do not use the service. Any additional terms for a paid plan will be shown before purchase. Mandatory rights under applicable law still apply.

Agreement to these Terms is separate from permission to share information with OpenAI or access your microphone, calendar or photos. Big Cal asks for those permissions separately. Reading these pages does not grant access to your information.

What Big Cal does

Big Cal helps you view, create and manage calendar events, use selected contacts, set calendar reminders, and work with optional voice, typing, scanning, practice and printing features. Available features depend on your device, permissions, account and plan. The first App Store release uses calendars available through Apple Calendar; direct Google, Outlook and Gmail account connections are not offered.

Big Cal is a calendar assistant. It is not an emergency service, medical service or a substitute for professional advice. An appointment reminder is not a guarantee that a notification will be delivered or noticed. Keep another way to remember information where a missed event could cause harm.

Your use and your information

Use Big Cal only for lawful purposes and only with accounts, calendars, images and information you are entitled to access or share. If you use the app for another person, have their permission and respect their choices. Keep account credentials secure and contact us if you believe someone has accessed your account without permission.

Do not try to bypass authentication, voice limits, purchase verification, ownership checks or other safeguards; disrupt the service; or use it to send unwanted invitations or misuse another person's information. We may restrict access when needed to investigate abuse, comply with law or protect people and the service, subject to applicable law.

You keep your rights in the information you provide. You authorize Actually Good Ideas LLC and its service providers to process that information as needed to provide the features you request, subject to your permissions and the Privacy Policy. This does not give us ownership of your calendar, photos or other content.

AI features and calendar changes

OpenAI supplies Big Cal's live AI voice and other optional AI processing. The spoken voice is AI-generated. Big Cal asks for permission before sharing information for these features. See How Big Cal uses OpenAI.

AI can misunderstand speech, misread a page or produce an incorrect answer. Check important names, dates, times, recipients and event details. Big Cal may create a single simple event directly when your request is clear and fully resolved. It asks for missing details and retains review safeguards for ambiguous requests, edits, deletion, recurrence and invitations. A success message should follow verification of the saved result; it is not a promise that another calendar provider has finished syncing everywhere.

You remain in control of permissions and the requests you make. Turning AI sharing off leaves manual Apple Calendar use and printing available. Some typed requests also use AI; typing is not a guarantee that information stays on the device.

Voice access and subscriptions

Manual Apple Calendar features do not require a voice subscription. Hosted free voice requires eligible sign-in or securely linked installation access. A verified monthly App Store subscription may provide voice access under its terms. Any free allowance is limited and is not a promise of unlimited or permanent free voice.

The planned US launch offer is Cal Voice Monthly at $6.99 per month, including 30 minutes of conversation with Cal in each monthly billing period. Calendar viewing, manual event creation and calendar reminders remain free. There are no automatic overage charges: when your voice allowance runs out, you can continue using the calendar by hand. No annual plan is offered at launch.

Before an App Store purchase, Apple and the app show the current price, billing period and included benefits. Monthly plans renew automatically unless cancelled through Apple. Apple charges your Apple account at purchase confirmation and for renewals under the terms shown at checkout. You can manage or cancel the plan in Apple’s subscription settings. Unused voice minutes do not carry over under the current monthly plan. Voice service is subject to the displayed allowance, availability and security limits.

Manage or cancel an Apple subscription through your Apple account. Refund requests are handled through Apple's process, subject to applicable law. Deleting Big Cal or your Big Cal data does not cancel a subscription. Restoring purchases may require the original Apple account and the Big Cal account linked to the plan; restore does not bypass ownership checks. Contact us if eligible access cannot be restored.

Apple and connected services

The App Store app license remains governed by Apple's standard end-user license agreement unless a valid custom license is supplied separately. These Terms describe Big Cal's service and do not replace Apple's purchase rules or mandatory consumer rights. Apple is not responsible for operating Big Cal's service or providing its support.

Apple, OpenAI, Auth0 and providers of accounts you have configured in Apple Calendar have their own terms and privacy practices. Their outages, permission changes or restrictions may affect Big Cal. You can disconnect supported accounts or revoke permissions through the relevant app or provider settings.

Availability and responsible reliance

We work to make Big Cal useful and dependable, but we do not guarantee uninterrupted availability, error-free AI responses, delivery of reminders, or compatibility with every account or device. Features may change, be interrupted or become unavailable. We will provide notices and remedies when required by applicable law or your purchase terms.

To the extent permitted by law, the service is provided as available, without additional warranties beyond those expressly offered or required by law. Nothing in these Terms excludes liability that cannot lawfully be excluded, or limits a guarantee, refund, cancellation or other consumer right that applies to you. These Terms do not impose mandatory arbitration or waive class-action rights.

Ending use and deleting data

You can stop using Big Cal at any time. Privacy & Safety includes a request to delete your Big Cal data. Deletion requires ownership verification and may remain pending if a required provider operation fails. It does not erase your Apple Calendar events, iPhone Contacts or exported copies, and does not cancel App Store billing. The Privacy Policy explains retention and deletion in more detail.

Changes and contact

We may revise these Terms as the service changes. We will identify the new version and give any notice or request for agreement required by law. Material changes will not remove rights that cannot legally be taken away. If you do not agree to a change, you can stop using the affected service and exercise any applicable cancellation rights.
