Terms of Service
Last updated 27 July 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. While inAmber is in beta, opening an account needs an invite code.
You must be eighteen or over to write and send messages. A person under eighteen may hold a free account in order to read something that was left for them, and cannot open it until an adult they have named has confirmed by email that they are content for them to. See the privacy policy.
4. Paying for it
inAmber is sold in tiers, from the Single Seal at £9.99 to The Amber Vault at £1,499. One off payments do not recur. The Pro plan at £14.99 a month renews until you cancel it. You may have a refund within fourteen days of buying, provided you have not sealed anything.
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, then when you died so would every message you wrote, 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.
If a message is delivered and never read, we keep trying to reach the person. We delete it only if they have not signed in at all for twelve months. A message somebody has chosen to leave unopened is never deleted for that reason alone. The privacy policy sets out exactly when we write to them.
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.
