Privacy policy

What Scalyx does with your data.

This page describes the Scalyx app as it works today. It was written from the app's own code, not from a generic template. Where a piece of information is missing, we say so.

Last updated on 22 July 2026.

In two minutes

Scalyx asks you for no account, no email address and no name. You download the app and you use it.

  • Your tasks, your notes, your moods and your conversations with the assistant are saved by your iPhone and synchronised into your private iCloud. Scalyx has no server holding that content, and therefore cannot read it.
  • There is one single moment when something leaves your iPhone on Scalyx's initiative: when you write to the assistant. What you tell it, along with the context of your agenda, is then sent to an artificial intelligence service so that it can answer you. Everything is detailed further down.
  • There is no audience measurement tool, no tracker, no advertising, and no third party analytics kit installed in the app.

Who is responsible

The data controller, in the meaning of the General Data Protection Regulation (GDPR), is the publisher of the app:

Publisher: Scalyx.
Contact: support@scalyx.app

Scalyx is published by one person alone. There is no designated data protection officer: requests arrive directly at the address above.

No account, no trackers

Scalyx does not ask you to create an account. The app collects neither your name, nor your email address, nor your date of birth, nor your location, nor your address book, nor your photos.

There is no audience measurement or advertising tracking kit in the app: no Google Analytics, no Firebase, no Facebook, no Mixpanel, no Amplitude, no Sentry, and no equivalent. No advertising identifier is read. No profile is built about you, and no automated decision is made about you.

Concretely, in the app's code, a single feature opens a network connection on its own initiative: the assistant. Everything else goes through Apple's own mechanisms (iCloud, the App Store) or through the subscription service described further down.

Where your tasks, your notes and your moods live

The content you create in Scalyx is saved through Apple's SwiftData mechanism, backed by CloudKit in its private database. Very concretely, that means this data goes into the iCloud space attached to your Apple Account, just like your notes or your photos.

This covers:

  • your tasks, their times, their sub-steps and their icons;
  • the notes in your capture inbox;
  • your mood journal entries;
  • the affirmations you mark as favourites;
  • your conversations with the assistant, so that you can reopen them later;
  • your settings and your internal backups.

The publisher of Scalyx has no access to that database. There is no Scalyx server holding a copy of it, no administration console, no export. Nobody at Scalyx can read what you write in your mood journal.

If you are not signed in to iCloud, or if synchronisation is unavailable, the app saves everything locally on the iPhone in the meantime. Nothing is lost, and nothing goes anywhere else for all that.

Managing your iCloud account is a matter for Apple and for Apple's privacy policy.

The assistant, the only moment anything leaves your iPhone

When you write or dictate a message to the assistant, the app sends over the network, using HTTPS:

  • your message, and the previous messages of the current conversation;
  • the context of your agenda: the titles, the dates and the time slots of your tasks for the next three weeks, as well as your recurring tasks. This is what allows it not to suggest a slot that is already taken;
  • the current date and time, and the language of the app.

This information passes through a technical relay, a Cloudflare Worker operated for Scalyx. That relay exists for one reason only: to keep the access key to the artificial intelligence service on a server, rather than locking it inside the app where it could be extracted. The relay does not log and does not store the content of your messages: it checks a technical token and the state of your subscription, adds the key, forwards the request and sends the answer back to you.

The relay then forwards to Anthropic's API (Claude), which produces the answer. Anthropic acts here as a processor. Its processing is covered by Anthropic's privacy policy: we invite you to read it, because we do not control its retention periods and we will not invent them here. Anthropic states on its side that it does not train its models on data sent through its API.

The legal basis for this transfer is the performance of the service you are asking for: as long as you do not write to the assistant, none of this leaves. The assistant is a feature you open, not a background task.

One point worth knowing. If you have imported your iPhone Calendar or your Reminders into Scalyx, the titles and the times of those events are part of the agenda context sent with your message. This is what keeps the assistant from scheduling something for you in the middle of an appointment. If you would rather they never left the device, do not turn on calendar import, or remove the access in your iPhone settings.

Finally, an honest word about what the assistant can do with your agenda. It never adds a task without you pressing the add button: a suggestion stays a suggestion. On the other hand, if you ask it to move, rename or delete an existing task, it acts on your agenda directly, and confirms it to you afterwards. For deletions, it asks for your agreement first.

The subscription

Scalyx is free to download and offers in-app purchases. Subscriptions are handled by Apple's App Store and by RevenueCat, a service that acts as a technical intermediary to know whether your subscription is active.

Scalyx never sees your payment method. No card number, no bank details, no billing address passes through the app or through its servers: everything happens between you and Apple.

RevenueCat assigns the installation an anonymous identifier, which does not contain your name and does not make it possible to find you in real life. That identifier is passed to the assistant's relay in order to check that the subscription is indeed active. RevenueCat's processing is covered by its own privacy policy.

Calendar and Reminders

Scalyx can show your iPhone Calendar events and your Reminders next to your tasks, to save you from typing everything again. Reading them happens on the device, through Apple's EventKit mechanism, and only after you have granted permission in the system dialog. You can withdraw it at any time in your iPhone settings.

These events are not sent to any Scalyx server, and Scalyx writes nothing into your calendar behind your back. The only exception is the one described above: when you talk to the assistant, the titles and the times of the imported events are part of the context that is sent.

Dictation

When writing takes too much energy, you can speak to the assistant. Speech recognition is handled by Apple's Speech framework, after you have granted permission for the microphone and for speech recognition. Scalyx keeps no audio recording: only the recognised text appears in the input field, and you are the one who decides to send it.

Depending on the device, the language and the iOS settings, Apple may process the recognition directly on the iPhone or on its own servers. That choice belongs to the system, not to Scalyx, and it is covered by Apple's privacy policy.

Notifications

Task reminders and the affirmation of the day are local notifications: they are scheduled by your iPhone, in advance, and triggered by it. There is no server pushing notifications to you, so there is no remote push token and no recipient list sitting somewhere.

For how long

What you create in Scalyx stays for as long as you keep it. Since you are the one holding that data, in your iCloud, there is no retention period decided by us: nothing is erased behind your back, and nothing is archived on our side.

The assistant's relay does not keep the content of the exchanges. For Anthropic, Apple and RevenueCat, the periods are the ones stated in their respective policies, which we cannot set in their place.

If you write to us at the contact address, we keep the exchange for the time it takes to handle your request, then we delete it.

Your rights

The GDPR gives you a right of access, rectification, erasure, restriction, objection and portability over your personal data.

With Scalyx, the most direct way to exercise them is also the simplest one: everything that concerns you is in the app, in your own hands. You can view, edit and delete every task, every note, every mood entry and every conversation, without asking us for anything. We cannot send you a copy of data that we do not hold.

For any question, any request, or to exercise a right with the publisher, write to support@scalyx.app. If the answer does not satisfy you, you can refer the matter to the data protection authority of your country. In France, that is the CNIL, cnil.fr.

Deleting everything

To completely erase what Scalyx has saved:

  1. uninstall the app from your iPhone;
  2. open the iPhone Settings, go to your Apple Account, then iCloud, then the list of apps that use iCloud, and delete the Scalyx data.

These two steps are enough, since no copy exists anywhere else. For a subscription in progress, cancelling is done in the App Store subscription settings, on Apple's side.

What this page does not say yet

For the sake of honesty, rather than filling the boxes with invented information:

  • Scalyx is published by an individual. This page therefore mentions neither a company registration number nor a published postal address. If you need full contact details as part of an official procedure, ask for them by email: they will be provided to you.
  • We cannot guarantee the retention periods applied by Anthropic, Apple, Cloudflare and RevenueCat. Their policies are what count, and they are linked above.
  • This page describes the app as it stands on 22 July 2026. If a feature changes the way data travels, this page will be updated and the date at the top will change with it.

Writing to us

A question about a specific point, a doubt, a wording that seems unclear to you: write to support@scalyx.app. A privacy policy that cannot be understood is of no use, and we would rather rewrite it than leave it vague.

Scalyx is an organisation and wellbeing app. It is not a medical device, it makes no diagnosis, and it does not replace the advice or the support of a health professional.
