Questions are grouped by the moment when they usually appear: from the first entry to reports and data security.
Basics
What feelink is and who it may help.
What is feelink and how does it work?
feelink is an app for calm self-observation. You write a short entry about wellbeing, sleep, treatment context, and daily rhythms, and the app organizes those notes into views and reports that are easier to discuss with a specialist.
Is this only for people with ADHD?
feelink was created with ADHD treatment monitoring in mind, but a diary for wellbeing, sleep, stress, and everyday observations may also support other conversations with a specialist. The app does not assume a diagnosis and does not interpret data as a medical decision.
Is feelink a medical application?
No. feelink is a self-observation and note-organization tool. It does not diagnose, recommend treatment, select doses, or replace consultation. Always make health decisions with a specialist.
Does the app work on a phone?
Yes. feelink is a Progressive Web App (PWA) - install it on your phone like a regular app from the browser, no app store download needed. Works on iOS, Android, and desktop.
Daily entries
What the diary looks like, how long it takes, and when to add context.
What exactly does the app track?
You can track mood, sleep, stress, focus, treatment context, activity, caffeine, side effects, rebound, and selected vital signs. You do not need to fill in everything - the form hides fields that do not make sense that day and suggests values from your previous entry.
How long does the daily entry take?
Usually about 2 minutes. The form suggests values from your previous entry, so you only change what was actually different. You can keep the entry short or add more detail when something matters that day.
What is the observer feature?
An observer is someone close to you who can add a short external perspective, for example on focus, calmness, communication, or task completion. You share a unique link, and their answers appear in your analytics. It is extra context, not a medical assessment.
Reports and conversations
What summaries show and how to use them during an appointment.
What analytics and reports does feelink offer?
feelink shows summaries, trends, week-to-week comparisons, and PDF reports. The goal is to organize observations: what repeats, what changes over time, and what may be worth bringing to an appointment. It is not an assessment of treatment effectiveness - medical conclusions should always be discussed with a doctor.
Can I show the data to my doctor?
Yes. You can prepare a PDF report or data export to make it easier to talk about the last few weeks. The report supports the conversation, but it does not replace an interview, examination, or specialist decision.
Plans and access
What is included in the basic plan, Pro, and one-time reports.
Is feelink free?
The basic plan lets you start a diary and export your data as CSV and JSON. Pro adds expanded PDF reports, premium exports, and collaboration features. Billing currency is PLN for Poland and EUR for other EU countries.
What is a one-time PDF report?
It is an option for people who need a single report for a specific appointment without starting a subscription. If you want to use reports regularly, it is worth checking the Pro plan.
Data and privacy
Where data is stored, how you manage it, and what you can delete.
Is my health data secure?
Data is stored on servers in the European Union, protected by TLS encryption and database-level isolation. Each user sees only their own entries. Details are described in the privacy policy.
How can I delete my data?
In your account settings, you'll find the option to delete all data. Under GDPR, you have full rights to delete, export, and transfer your data. You can also write to us at privacy@feelink.app.
What languages is the app available in?
feelink is available in Polish and English. The language is automatically detected from your browser settings on first visit, and you can change it anytime in the app settings.
Medical boundaries
How to use observations responsibly without making treatment decisions on your own.
Can I change treatment based on a report?
Do not change treatment on your own based on a report, chart, or single entry. feelink helps you gather observations, but decisions about medication, doses, and therapy changes require consultation with a specialist.
How should I talk about rebound or side effects?
Write down when the symptom appears, how long it lasts, how intense it is, and what happened that day. This can be a useful starting point for a conversation. If symptoms are sudden, strong, or worrying, contact a specialist.
