Terms of Use

Effective October 22, 2026

These terms are an agreement between you and GODAAN SERVICE PRIVATE LIMITED ("we", "us") for your use of Mermaid: the Mermaid iPhone app, Mermaid for Mac, Mermaid for Android when it is available, and the online services they use. By creating an account or using Mermaid, you agree to them.

1. What Mermaid does

Mermaid lets you see and control your Mac from your phone and ask an assistant on your Mac to carry out tasks for you. It needs the Mermaid app on your phone, Mermaid for Mac running on your Mac, and a Mermaid account. Some features need your Mac to be awake and online. Mermaid has a free plan and optional paid subscriptions, described in section 2.

2. Plans and subscriptions

  • Mermaid has a free plan with an allowance of AI usage that renews periodically. Live Screen, Take Over and sending files do not use it.
  • Mermaid Lite and Mermaid Pro are optional auto-renewing monthly subscriptions with more AI usage and longer tasks. You can buy them in the Mermaid iPhone app, through Apple's In-App Purchase, or in Mermaid for Mac, through Dodo Payments. You can have one subscription at a time: manage it with the store you bought it from.
  • In the iPhone app, the price is shown before you subscribe. Payment is charged to your Apple Account when you confirm the purchase. A subscription renews automatically each month unless you cancel it at least 24 hours before the end of the current period, and your Apple Account is charged for the renewal within 24 hours before the period ends.
  • You can manage or cancel a subscription in your Apple Account settings, or from Plan & Billing in the app. Cancelling stops future renewals; your plan stays on until the end of the period you paid for.
  • Refunds are handled by Apple under its policies. Deleting your Mermaid account does not cancel a subscription: cancel it with Apple first.
  • In Mermaid for Mac, Dodo Payments sells subscriptions as our merchant of record and handles payment, applicable taxes, invoices and order questions. Prices are in US dollars, include applicable taxes, and are shown at checkout before you pay. A subscription renews automatically each month, and Dodo Payments charges the payment method you saved at checkout, until you cancel.
  • You can cancel a Mermaid for Mac subscription from Plan & Billing in Mermaid for Mac (Manage subscription). Cancelling stops future renewals; your plan stays on until the end of the period you paid for. An upgrade from Lite to Pro starts at once and Dodo Payments charges the prorated difference; a change from Pro to Lite starts at your next billing date.
  • Refunds of Mermaid for Mac subscriptions are handled by Dodo Payments under its refund policy and applicable law; you can also contact us at support@addmermaid.com. A full refund of a period ends the paid plan for that period. Deleting your Mermaid account cancels a Mermaid for Mac subscription, without an automatic refund.
  • When Mermaid for Android is available, subscriptions bought in it are billed through Google Play, and are managed, cancelled and refunded through Google Play under Google's policies. Deleting your Mermaid account does not cancel them: cancel them in Google Play first.
  • Your plan applies to your Mermaid account. We may change plan allowances, limits or prices; if a change affects an active subscription, we will tell you in advance, and Apple asks for your consent to a price increase where its rules require it.

3. Your account

Give accurate information when you create your account and keep your sign-in secure. You are responsible for activity on your account and on the phones and Macs you pair with it. Tell us promptly at support@addmermaid.com if you think someone else has used your account.

4. Your Mac and your instructions

  • Use Mermaid only with Macs you own or are allowed to control.
  • Mermaid acts on your Mac when you ask it to from a paired phone. You are responsible for the tasks you ask for, the actions you approve, and their results, including messages sent, files changed and purchases made.
  • Before actions such as sending, deleting or buying, Mermaid asks for your approval. Review what you approve. You can stop a task, take over, or unpair a Mac at any time.
  • Some actions need permissions on your Mac (for example Screen Recording and Accessibility) that you grant and can remove in macOS.

5. AI features

Mermaid's AI features use services from third-party providers, including a speech service for voice requests, and only after you allow them in the app. Mermaid for Mac carries out tasks on your Mac and applies Mermaid's own safety rules, which the AI cannot skip. AI can make mistakes: it may misunderstand a request or take a step you did not expect. Check results that matter to you. How your information is handled is described in our Privacy Policy.

6. Acceptable use

You must not use Mermaid to:

  • access or control a device without permission, or break the law;
  • harm, harass or deceive others, or create or send spam or malicious software;
  • violate the rights of others, or the terms and usage policies of the services Mermaid works with;
  • get around usage limits, security measures or access controls, or interfere with Mermaid's services or relay;
  • copy, modify or reverse engineer Mermaid, except where the law allows it.

We may suspend or end access for anyone who breaks these rules or puts others or the service at risk.

7. Your content

Your requests, files and screen content stay yours. You allow us and the service providers named in the Privacy Policy to process them only as needed to provide Mermaid to you.

8. Our software

We grant you a personal, non-exclusive, non-transferable, revocable licence to use Mermaid on devices you own or control, under these terms. Parts of Mermaid are open-source software under their own licences, which are in the app under Help & Legal › Licenses. Nothing in these terms limits your rights under those licences.

9. Ending your use

You can stop using Mermaid at any time and delete your account in the app (see Delete your account). We may end or suspend these terms or your access if you break them, if required by law, or if we stop providing Mermaid, with notice where reasonable.

10. Disclaimers

Mermaid is provided "as is" and "as available". To the extent the law allows, we make no promises that it will be uninterrupted, error free, or that tasks will succeed, and remote access depends on your devices and networks. Nothing in these terms limits rights you have under consumer protection law that cannot be limited.

11. Limitation of liability

To the extent the law allows, we are not liable for indirect, incidental, special or consequential losses, or for loss of data, profits or business, arising from your use of Mermaid, and our total liability for any claim relating to Mermaid is limited to the greater of the amount you paid us for Mermaid in the 12 months before the claim and USD 50. This does not limit liability that cannot be limited by law, such as for death or personal injury caused by negligence, or for fraud.

12. Apps from the App Store

If you got the Mermaid iPhone app from Apple's App Store:

  • These terms are between you and us, not Apple. We, not Apple, are responsible for the app and its content.
  • Your licence to use the app is limited to Apple-branded devices you own or control, as allowed by the Usage Rules in Apple's Media Services Terms and Conditions.
  • Apple has no obligation to provide maintenance or support for the app. Contact us for support.
  • If the app fails to conform to an applicable warranty, you may notify Apple, and Apple will refund the purchase price, if any. To the extent the law allows, Apple has no other warranty obligation for the app.
  • We, not Apple, are responsible for addressing any claims about the app, including product liability claims, claims that it fails to meet legal or regulatory requirements, and consumer protection, privacy or similar claims.
  • We, not Apple, are responsible for the investigation, defence, settlement and discharge of any claim that the app infringes a third party's intellectual property rights.
  • You confirm that you are not located in a country subject to a U.S. Government embargo or designated as a "terrorist supporting" country, and are not on any U.S. Government list of prohibited or restricted parties.
  • You must comply with any third-party terms that apply when using the app.
  • Apple and its subsidiaries are third-party beneficiaries of these terms and may enforce them against you.

13. Mermaid for Android and Google Play

When Mermaid for Android is available, it is distributed through Google Play:

  • Google Play's terms of service apply to downloading the app from Google Play and to purchases made in it.
  • These terms are between you and us, not Google. We, not Google, are responsible for the app and its support.

14. Changes to these terms

We may update these terms. If a change is significant, we will tell you in the app before it takes effect. If you keep using Mermaid after that, the new terms apply; if you don't agree, stop using Mermaid and delete your account.
