Terms and Conditions

Last updated 16 October 2026

1. Agreement to these terms

By using inAmber, which is operated by Capitalizt Ltd (company number 16890768, registered at 128 City Road, London EC1V 2NX), you agree to these terms. If you do not agree, please do not use it.

2. What inAmber does

inAmber lets you write, record or upload messages, seal them, and schedule them to reach the people you choose at a moment you choose. It includes a guardian arrangement, where somebody you trust confirms that a moment has arrived so a message can be released.

3. Your account

Give us accurate information and keep it current. You are responsible for your password and for what happens under your account.

You must be eighteen or over to open an inAmber account; you may make messages for people of any age, but for anyone under eighteen only after naming their parent, guardian or caregiver, who receives those messages first.

Accounts are for people eighteen or over. Something left for a person under eighteen goes first to the adult they were named with, who can hand it over when the moment feels right. Anything still kept goes to them directly on their eighteenth birthday. See the privacy policy.

4. Paying for it

inAmber is sold as packs: Start with one, a pack for one person or for one group, Family of four, Generations, and Five more messages. Prices are shown in pounds, euros, US dollars, Australian dollars or rand, depending on where you are, and you pay exactly the price shown, including any VAT. Anywhere else, checkout shows your own currency at our payment provider's rate. Payments are one off and do not recur.

You can cancel within 14 days of paying by emailing hello@inamber.ai, as long as you have not yet started a message. Your pack begins when you start your first message, and from then it can't be cancelled. When we refund a pack, it closes and nothing in it is delivered. If anything we provide isn't right, we will put it right or refund you.

If a message is deleted before it is delivered, its place comes back and can be used again. A delivered message always counts as used.

Each pack gives you three years from the day you buy it to write and seal its messages. Sealed messages are delivered on the days you set, up to 25 years from the day you bought the pack. Anything you have not sealed when the three years end stays in your account for you to read and copy, but it is not delivered.

For Family of four and Generations, the three years are counted from the day you buy the bundle, for every pack in it, including packs you choose later. Start with one has the same three years.

Start with one. Start with one is one message to one person, and can be bought once per person: we check this by account, mobile number and payment card. If you buy a pack or bundle within thirty days, its price is reduced by the price you paid for Start with one, once, on that one purchase. The reduction cannot be used on Five more messages or on a later purchase, has no cash value, and is never paid out or refunded.

A recipient never pays. If somebody has left you a message, the account you need in order to read it costs nothing, because the person who wrote to you has already covered it.

5. What you write stays yours

You own everything you create here. You are responsible for what your messages contain, and you must not use inAmber to send anything illegal, harmful or abusive.

What encryption here does and does not mean

Everything is encrypted, and if our database were copied the contents would be unreadable. But inAmber is not zero knowledge and this is not end to end encryption in the strict sense. We hold the key, so we are technically able to decrypt what you write.

That is deliberate. If the only key lived on your device, every message you wrote would go with it, and a service that cannot deliver a letter to your daughter twenty years from now is not a legacy service.

What we undertake instead: we do not read your messages, we do not analyse them for advertising or for training models, access is restricted and logged, and a message is only decrypted when the person you named opens it, or when you do.

6. Delivery

We will make every reasonable effort to deliver your messages when you asked us to. Delivery depends on the contact details you gave us still being valid and on the guardian arrangement working, so we cannot guarantee it in every circumstance.

A message that has been delivered is never deleted, whether or not it has been opened. The privacy policy sets out how long everything else is kept.

7. Guardians

A guardian is somebody you name to confirm that a moment has arrived. By naming them, you authorise them to tell us that, which releases the message. A guardian never sees what you wrote.

8. Data protection

We handle your personal data in line with our privacy policy and with the UK General Data Protection Regulation and the Data Protection Act 2018. Your rights are set out on your data rights.

9. Limitation of liability

To the fullest extent the law allows, Capitalizt Ltd is not liable for any indirect, incidental, special, consequential or punitive loss arising from your use of inAmber. Our total liability will not exceed what you have paid us in the twelve months before the claim.

10. Governing law

These terms are governed by the law of England and Wales, and the courts of England and Wales have exclusive jurisdiction over any dispute.
