CallbyMi Terms of Service

Updated October 30, 2026

1. Purpose

These terms set the conditions for using the CallbyMi app, website and related services (the "service") provided by Foo AI Corp. ("we"), and the rights and duties of you and us.

2. Definitions

  • "User": a person who agrees to these terms and uses the service
  • "AI assistant": the voice and text assistant we run with AI
  • "AI call": an internet voice call the AI assistant places to you through the app at a time you scheduled
  • "Call plan": the rule you set for when and about what you receive an AI call
  • "Subscription": the paid CallbyMi plan bought through an app store

3. Publication and changes

We publish these terms on the website (callbymi.com) and in the app.

We may change these terms within the limits of the law. Changed terms take effect on the day they are published, and we tell you separately in the app or by email about changes that are adverse to you or important. If you do not agree with the changed terms, you may stop using the service and delete your account at any time, and you may cancel a subscription as section 9 describes.

4. Eligibility

You must be at least 14 years old to use the service. We check this with your year of birth at sign-up.

If a minor under 19 (the age of majority in Korea) buys a subscription without a legal guardian's consent, the minor or the guardian may cancel that contract. Where the law of your country sets other rules for minors, those rules also apply.

5. Accounts

You can sign up with Apple, Google or email (confirmation email required). A guest account, used without signing up, can use the calendar, drafts and the text assistant only; registering a device and receiving AI calls need a full account.

Keep your account secure and do not use another person's account or details. If you learn that your account has been misused, tell us at once.

6. The service

An AI call is an internet voice call inside the app, not an ordinary call to a phone number. You cannot use the service to call other people, and you cannot use it to call emergency services (such as 911, 112 or 119).

We provide:

  • AI calls at the times you schedule (preparing for an event, a morning briefing, birthdays, medication reminders, subscription renewal checks, reminders you write yourself)
  • handling of requests during a call, such as calling back later, moving an event or adding a task
  • call summaries and the memories you approve
  • drafting events and call plans with the AI assistant
  • viewing Google Calendar (read-only) and device calendar events
  • call languages: English, Korean, Japanese, Spanish, Chinese (Simplified)

7. AI disclosure and limits

CallbyMi calls and the assistant run on generative AI. Every AI call says in its first sentence that it is an AI assistant, and drafts and summaries made by the AI are labelled as such. The voice on the call is synthesised by AI.

The AI can mishear you or say something that is not correct. Requests that change your schedule are confirmed by the AI before they are carried out, and a change has happened only when the result is shown as completed. Please check important events and decisions yourself.

8. Medication reminders and medical disclaimer

CallbyMi medication reminders only tell you what you entered at the time you chose. They are not medical advice, diagnosis or treatment, and CallbyMi is not a medical device. The AI assistant does not give advice about which medicine to take, doses or how to take it.

Follow your doctor's or pharmacist's instructions. If you feel unwell or have an emergency, do not rely on the service — contact a medical provider or emergency services at once.

9. Subscriptions

Subscriptions are bought only through Apple App Store or Google Play billing. The price, the included talk time, the maximum length of one call and whether a free trial applies are shown on the purchase screen before you pay.

A subscription renews automatically for the same period and price unless you cancel it. You can cancel in the app store's subscription settings (App Store apps.apple.com/account/subscriptions, Google Play play.google.com/store/account/subscriptions). For a product with a free trial, cancelling before the trial ends means you are not charged. Deleting the app or the account does not cancel a subscription.

The usage limits of free use and of the subscription are shown in the app. When a limit is used up, AI calls may not be placed until the next period.

10. Withdrawal and refunds

You may withdraw a purchase within 7 days of buying it. Where the supply of digital content has already started, such as AI calls already used under a subscription, withdrawal may be limited as far as the law allows; we let you know this in advance by offering a free trial or a trial call.

Refunds are requested through the app store you paid with (App Store reportaproblem.apple.com, Google Play support.google.com/googleplay/answer/2479637). Besides the store's own process, we cooperate with the store so that a refund is made in the following cases, and accept requests at contact@callbymi.com where needed:

  • a minor bought without a guardian's consent and the contract was cancelled: in full
  • you could not use the paid service properly because of our fault: for the part you could not use
  • other cases where the law provides for a refund

11. Our duties, changes and interruptions

We work to provide the service reliably. Calls may still arrive late or not at all because of device settings (Do Not Disturb, battery saving, notification permission), network conditions, or outages of app stores or carriers. We never place a late call outside the time window you set, and we tell you by an ordinary notification about a call we could not place.

We may change or stop parts of the service for operational or technical reasons. If we change or stop a paid service, we tell you in advance and compensate you for the period you could not use, as the law provides.

12. Your duties

When you enter the names of family or friends, for example for a birthday reminder, enter only what is needed.

You must not:

  • enter another person's information against their wishes, or use the service to harass anyone
  • use the service or the AI assistant in abnormal ways or get around usage limits (for example by signing up repeatedly)
  • reverse engineer the service or put undue load on our servers
  • break the law or these terms

13. Restriction and termination

You can end the contract at any time by deleting your account in the app settings.

If you breach section 12, we may restrict your use or end the contract after telling you why and for how long. You can object at contact@callbymi.com; if the objection is justified we lift the restriction at once. We give advance notice except where a breach of the law is obvious and urgent.

14. Liability

If we cause you damage intentionally or negligently, we compensate you as the law provides.

We are not liable for damage caused by events beyond our control, such as natural disasters or your device, network or app store, or for damage caused by your own fault, unless we acted intentionally or with gross negligence. This section does not limit any right that consumer law gives you.

15. Content

The rights to the events and notes you enter and to your call summaries and memories stay with you. We process them only as far as needed to provide the service and do not use them to train AI models.

The rights to the service, its design and software belong to us.

16. Privacy

We protect your personal information under our privacy policy. Calls are not recorded. See the privacy policy (callbymi.com/privacy) for details.

17. Where the service is offered

CallbyMi is not offered in the European Economic Area (the 27 EU countries, Iceland, Norway and Liechtenstein), the United Kingdom and mainland China.

18. Governing law and disputes

These terms are governed by the law of the Republic of Korea. A lawsuit about the service is brought in the court that has jurisdiction under the Korean Civil Procedure Act. If you live in another country, you keep every right the consumer law of your country of residence gives you.

You may also apply for mediation to a dispute mediation body such as the Korea Consumer Agency.
