1. Data controller

The controller for ADHD Focus is Dr. Thilo Reichenbach, Holzgasse 42 A, 53227 Bonn, Germany. Contact hello@adhd-focus.app.

2. Our approach

ADHD Focus uses no advertising tracking, analytics tools or non-essential cookies. The app is designed to give you a quiet place to work.

3. Demo and existing local data

Without an account, ADHD Focus is available as a view-only demo. It does not save any new tasks or notes of your own. Local data from earlier versions can stay on the device until you import it after signing in, export it or delete it. Existing local data may be lost if browser data is cleared, the device is lost or its local storage is damaged.

4. Account and cloud sync

An account is required for ongoing use. We process your email address, technical user ID, a random device identifier, trial period, device activation and switch count, profile, access and subscription status, and the app data you save. This information supports sign-in, recovery, plan-dependent access and synchronization. Appwrite provides the technical service for sign-in and cloud sync.

Attachments such as photos or documents are synchronized only if you choose them yourself, server-side attachment uploads are enabled and the files are within the size limits. After the trial, existing attachments remain available to view, download or delete. New attachments require the appropriate subscription.

To keep the service running, the provider may also record standard technical logs, including timestamps, IP addresses, browser or device information, and error messages. ADHD Focus does not request location permission or process your device’s precise location. An IP address can at most be used to infer an approximate region.

5. Content that can be stored

Depending on how you use it, ADHD Focus stores tasks, notes, projects, first steps, due dates, recurrence, delegation notes, quality levels, focus times, check-in and check-out notes, settings, and optional attachments such as photos or documents. You enter this content yourself. Only save information you are comfortable keeping in a task or note app.

Tasks, notes and check-in or check-out entries may contain health-related or other sensitive information if you enter it yourself. ADHD Focus does not request diagnosis or treatment information. When cloud sync is on, the information you enter is synchronized with your account like your other app data.

6. Dictation and the microphone

The app requests microphone permission only when you start dictation. On Android, ADHD Focus uses the operating system’s speech recognition service. Depending on your device and system settings, that service may send audio to its provider’s servers for recognition. ADHD Focus does not store the original audio recording. It puts only the recognized text into the input field. The text is saved or synchronized only when you save it as a task or note.

7. Legal basis, storage and deletion

We process data as needed to provide the app. Using optional features such as cloud sync is your choice. You can delete local data in your browser or in the app. In account settings, you can permanently delete your account and the associated cloud data.

See Delete your account and data for instructions.

8. Your rights

You can request access, correction, deletion, restriction of processing or data portability, or object to processing where the legal requirements are met. You can also lodge a complaint with a data protection supervisory authority.
