Simple privacy principles.

This Privacy Policy explains how Axt Software handles information through this website, contact forms, newsletter signups, analytics, and Axt Software-owned apps where specified.

Last updated: October 30, 2026

Core policy

Axt Software builds privacy-first software. We do not sell personal data and we do not use third-party advertising trackers in our apps.

Scope

This policy covers both axtsoftware.com and Axt Software apps. The studio-level principles below apply across products, and app-specific details are listed in the app sections on this page.

Who is responsible for your data

Axt Software, based in Gothenburg, Sweden, is the data controller for the personal data described in this policy, unless a section below says otherwise. To ask a privacy question or use your rights, use the contact link at the bottom of this page.

What we do not do

We do not sell personal data.
We do not run ad-network tracking SDKs in the reviewed app codebases.
We do not use tracking cookies for advertising.

Why we process your data (legal basis)

To provide an app or service you asked for, including your account, syncing, notifications, support and purchases: performance of a contract.
To process your data with AI where an app asks for your agreement, such as BriefNotes sending voice notes and text to OpenAI, and for optional choices such as newsletters: your consent. You can withdraw consent at any time, which does not affect processing that happened before.
To keep our services secure, prevent abuse, fix problems and understand aggregate website use: our legitimate interest in running reliable and safe services.
To keep records we are required to keep, such as accounting records: legal obligation.

Your rights

You can ask us for access to your data or a copy of it, and to correct or delete it. You can also ask us to restrict how we use it, object to processing based on legitimate interest, and receive data you gave us in a portable format. To use these rights, use the contact link at the bottom of this page. We will reply within one month. Some data may be kept where the law requires it, or where it belongs to a business as a business record.

You also have the right to complain to the Swedish Authority for Privacy Protection (IMY) at imy.se, or to the data protection authority where you live.

Contact forms and newsletter

If you contact us or sign up for our newsletter, we use your name, email address and message to reply to you or to send you the newsletter. You can unsubscribe at any time by contacting us.

Analytics

We use privacy-first analytics on the website to understand aggregate traffic and site reliability. This does not rely on ad-tracking cookies.

Campaign attribution

If you arrive through a campaign link containing UTM parameters, those campaign values are stored in sessionStorage for the current browser tab and may be included if you submit a relevant campaign form or support action. This uses first-party session storage and does not use advertising cookies or third-party advertising tracking.

Yes Theory concept validation

If you support the Yes Theory app concept, the website stores the time of support and limited referral or UTM source information when available. Before the vote is submitted, you can choose whether a random campaign identifier may be saved in your browser's local storage to recognize your vote across tabs, refreshes and ordinary network changes. If you decline, your vote is still counted without saving the voting identifier in browser storage. If allowed, the identifier remains until you remove it through the voting page or clear the site's browser data.

When you allow the identifier, the server combines it with a private salt and stores only the resulting one-way hash; the original identifier contains no name, email address, IP address or device details. If you decline, the server uses an unrelated one-time record key to count the vote, and a temporary in-page reference links your optional download-intent answer during that interaction. Neither value is saved in your browser. No account, name or email address is requested. These records are used only to measure genuine interest in the concept and, when permission is given, protect the public count from simple repeated clicks.

How app data is handled

Each app only processes data required for its features. Some apps operate mostly on-device, while others use connected services for accounts, sync, notifications, or billing. See each app section for exact details.

Business apps: data your organisation adds

In BriefNotes, each business decides what to record about its own customers and contacts. For that data, the business is the data controller and Axt Software processes it on the business's behalf, under an agreement with that business. If you are a customer of a business that uses BriefNotes, contact that business first about your data. Axt Software is the data controller for account, billing, support and security data.

Third-party services

When you enable relevant features, apps may communicate with service providers such as cloud storage APIs, authentication/back-end platforms, notification services, or billing platforms. We list those providers per app below.

International transfers

Some of our service providers process data outside the EU/EEA, including in the United States. When they do, we rely on an adequacy decision, such as the EU-US Data Privacy Framework where the provider is certified, or on the European Commission's Standard Contractual Clauses.

Retention and deletion

We keep personal data only for as long as it is needed for the purpose it was collected for. Data retention differs by app and feature. Where supported, account deletion and cleanup behavior is described in each app section. Support requests are kept for 24 months. Accounting records are kept for as long as Swedish law requires.

Children

BriefNotes is a business service and is not intended for children. Our apps are not directed at children under 13, and we do not knowingly collect their personal data.

Changes to this policy

We update this page when our practices change and show the date of the latest update at the top.
