These Terms of Service ("Terms") are a legal agreement between you and:
Lukasz Tkacz, trading as Scara NIE: Z4291451R Address: Cortijo el Rincón, 1, 29314, Huertas del Río, Archidona, Málaga, Andalucía, España Contact: [email protected]
I operate Scara as an individual (autónomo) under Spanish law. By activating an access code and creating a password, you agree to these Terms. If you do not agree, do not activate your code.
These Terms govern your participation in the Scara beta. They are not the terms of a finished commercial product — they describe a service that is still being developed and tested.
Scara is an AI-assisted self-reflection tool. You write; Scara is designed to respond with questions rather than answers, summaries, or advice. The aim is to help you think more clearly using your own words.
The AI does have one designed exception: if a conversation moves into territory that involves genuine distress, self-harm, or crisis, Scara will stop, tell you plainly that it has reached the limit of what it should do here, and point you toward real human support. It will not name or interpret what it detected. This is described in Section 7 below.
Legal statement: Scara is not a medical device, therapy service, counselling service, crisis service, or mental health platform. Nothing Scara produces — no question it asks, no response it generates — constitutes professional advice of any kind: medical, psychological, legal, financial, or otherwise. Scara is not a substitute for professional care. If you are experiencing a mental health crisis, are in danger, or need immediate support, please contact your local emergency services or a crisis helpline — not Scara.
Scara is in early, invite-only beta. Access is granted via individual access codes distributed personally by me. These Terms apply from the moment you activate your code.
Access codes are personal and non-transferable. Do not share your access code with anyone else.
Beta access is time-limited. Access codes expire after a fixed period from activation. When your access expires:
I make no commitment that beta access will be extended, that Scara will continue operating in its current form, or that the beta will lead to a public product. This is a test. I am grateful you are part of it.
Your data is accessible for as long as the beta remains online. If the beta ends — whether discontinued, replaced by a public launch, or otherwise taken offline — access to the app and any data held within it may cease without further notice. Because your journal content is stored locally on your device (not on my servers), locally stored data will remain on your device after the service goes offline; however, you will no longer be able to open, read, or export it through Scara once the app is unavailable.
Advance notice cannot be guaranteed. Because Scara does not store contact information linked to your account — by design — there may be no way to reach you before the service goes offline. This is a known risk of the architecture. Export anything you want to keep before your beta access expires. Do not treat Scara as long-term storage for content that matters to you.
Feedback. If you have thoughts, reactions, or observations about Scara — including critical ones — I want to hear them. [email protected] is a real address read by a real person.
To use Scara, you create a password at the point of first access. This password, combined with your access code, derives the encryption key that protects your journal content.
There is no password recovery. By design.
Your password is never stored — not on my servers, not anywhere accessible to me. If you lose your password, your journal content becomes permanently inaccessible. I cannot restore it for you, even with full proof of identity, because there is nothing on my end to restore it from. The encryption is client-side: the key lives only in your browser during your session, and is gone when you close the tab.
At the point of creating your password, you are asked to confirm that you understand this. That confirmation is not a formality — please read it before ticking it.
You are responsible for:
Everything you write in Scara belongs to you. I make no claim to ownership of your journal content. Your conversations are encrypted on your own device before storage, and I hold no stored, decryptable copy. The only moment your content exists in the clear on Scara's infrastructure is the instant of sending — when it passes through a server relay to reach Anthropic's AI models. At that point it is processed transiently and not stored or retained by Scara.
The one moment your content leaves your device is when you send a message, at which point the text of your current message and your recent conversation history is transmitted to Anthropic to generate a response and to run an automated safety check. Both uses are covered by the same Data Processing Agreement with Anthropic, which does not use your content to train its models. This is covered in full in the Privacy Policy.
You are entirely responsible for what you write. Because your content is encrypted client-side before storage, Scara does not and cannot monitor, audit, or review your journal entries for legal compliance. An automated safety check runs on each message as described in Section 7, but this is not a content-compliance mechanism. You agree not to use Scara to store or transmit content that is unlawful, or that violates the rights of others, and you acknowledge that the legal burden of this compliance rests solely on you.
Content about other people. If you write about other people in your journal — which is a normal thing to do when reflecting on your life — be aware that this content will be transmitted to Anthropic as part of message processing, as described above.
Scara's approach to your data is set out in full in the Privacy Policy. These Terms do not repeat it, but a few things are worth naming here because they are material to what you are agreeing to:
By using Scara, you acknowledge that the encryption design means I cannot recover your data if you lose access to it, and you accept that risk.
Scara's AI operates within a designed boundary. In normal use, it asks questions and does not conclude — it does not tell you what your writing means, what you should do, or what state you are in.
The one exception: if a conversation moves into territory that indicates genuine distress, self-harm, or crisis, the AI will stop. It will tell you that something has moved outside what it is built to hold, without naming or interpreting what it detected, and point you toward real human support. It describes only its own limit and a direction out — not your state, and not a conclusion about you.
When this happens, that conversation is locked: you will not be able to send new messages in it. The conversation content remains readable, exportable, and deletable throughout — only the ability to continue that particular conversation is suspended. The lock lasts for up to 180 days, after which it expires automatically. You can start a new conversation at any time. This is designed behaviour, not a malfunction.
This safety mechanism is not a crisis service. Scara is not equipped to handle emergencies. The floor exists because an AI should not try to hold what belongs with a real person — it does not exist because Scara is a mental health tool that has detected something clinical. If you are in genuine crisis, please contact emergency services or a crisis helpline directly.
You can delete your account at any time via the Settings menu. Deletion requires password verification, is immediate, and is irreversible.
What happens on deletion:
Rate-limiting data (short-lived request counters) may persist briefly after deletion — these expire automatically within 60 seconds to 24 hours depending on type, and contain no content.
Safety-lock records, if any exist, are keyed to conversation IDs rather than your access code and expire automatically within 180 days. They cannot be individually located or deleted, because there is no stored link between them and your account.
If you wish to delete your account but cannot access the app, email [email protected] with your access code. Your access code is the operative identifier for this request. Please note that manual deletion via email only removes your access record from the server. Because the server cannot communicate with an unauthenticated device, your local browser storage will not be cleared automatically — you will need to clear your browser's local storage manually to remove the locally stored encrypted journal files. If there is any reason to doubt the legitimacy of a request, I may ask for additional context — this is an abuse safeguard, not a second required credential.
Scara is in beta. It is unfinished. By participating, you accept that:
Scara is for adults aged 18 and over. By activating an access code, you confirm that you are at least 18 years old.
If I become aware that someone under 18 has used Scara, I will delete their account.
Scara is provided free of charge during beta. To the maximum extent permitted by applicable law:
I am not liable for any indirect, incidental, consequential, or speculative loss arising from your use of Scara — including loss of data, loss of access to your journal, or any outcome resulting from acting on or in response to anything Scara produces.
Nothing in these Terms limits or excludes my liability for:
As a consumer in the EU, you have statutory rights that these Terms do not affect.
If these Terms change in a material way, I will update the date at the top and notify active users directly, with at least 30 days' notice before the change takes effect. If you do not agree with the updates, you can export your data and delete your account via the Settings menu before the new Terms take effect.
Scara records the version of these Terms you accepted and the date of acceptance. If the Terms are updated, you will be asked to review and accept the new version before continuing to use the service.
For minor, non-material corrections — fixing a typo, clarifying existing wording without changing meaning — the date will be updated and no separate notification will be sent.
These Terms are governed by the laws of Spain. Any dispute arising from these Terms or your use of Scara will be subject to the jurisdiction of the courts of Málaga, Spain, without prejudice to any mandatory right you have as a consumer to bring proceedings in the courts of your country of residence.
As a consumer in the EU, you also have the right to access the European Commission's online dispute resolution platform at ec.europa.eu/consumers/odr.
Entire agreement. These Terms, together with the Privacy Policy, constitute the entire agreement between you and me regarding your use of Scara during the beta.
Severability. If any provision of these Terms is found to be unenforceable, the remaining provisions continue in full force.
No waiver. Failure to enforce any provision of these Terms on one occasion does not waive the right to enforce it on another.

These Terms are written in plain language wherever possible. If anything is unclear, please ask.
