Privacy Policy

Last updated: 14 October 2026

Who is responsible

Fitt is made and run by Uglješa Erić, an individual developer in Serbia, who is the controller of your personal data. Contact: ugljesa.eric@gmail.com.

What Fitt collects

• Account: email address, display name and password (stored only as a one-way hash).
• Profile: sex, birth year, height, weight and goal weight, activity level, time zone, language, gym days and time, equipment, fasting and eating plan, and notification preferences.
• What you log: meals and foods, exercise and workouts, supplements, plans for tomorrow.
• Health data you allow: from Apple Health (iPhone) or Health Connect (Android): weight, steps, workouts, active energy, sleep, resting heart rate and heart-rate variability. Fitt can also write the meals you log back to Apple Health or Health Connect.
• Coach: your chats with the coach, short facts the coach remembers (for example an injury or a food you don't eat), and the notes and reviews it writes for you.
• Photos and voice recordings you take in the app (meals, nutrition labels, workout plans, spoken logs). They are sent for processing and are not stored by Fitt afterwards; the text or entries made from them are kept as part of your log or chat.
• Reminder timing: which reminders you act on, so Fitt can send them at better times.
• Partner (optional): if you link with a partner, the link and your sharing settings.

Fitt has no ads, no analytics or tracking tools, and does not collect your location or contacts.

Why it is used

Only to run the app for you: calorie and protein targets, logging, training plans, reminders, progress, and the AI coach. Health data is never used for advertising or marketing and is never sold.

Where it is kept and who processes it

• Microsoft Azure hosts Fitt's server and database in the EU (Sweden Central).
• Azure OpenAI (Microsoft) processes meals you type, photos, voice recordings, coach chats and your health numbers to read food and to write the coach's answers. This processing is not limited to the EU. Under Microsoft's terms this data is not used to train AI models.
• Open Food Facts receives only the barcode number when you scan a product that Fitt doesn't know yet.

The developer can technically see the data on the server and looks at it only to run and fix the service. Server logs keep technical request details (not what you typed or said) for 30 days.

Your partner

If you link with a partner, they see only what you choose to share: streaks, training, fasting and steps. Your weight and calories are never shared. You can change this or disconnect at any time in the app.

Legal basis

Fitt processes your data to provide the service you signed up for, and processes health data and sends data to AI only with the consent you give on the notice shown before first use. This follows the EU General Data Protection Regulation and Serbia's Law on Personal Data Protection.

How long it is kept, and deleting it

Your data is kept while you have an account. In the app, You › Profile and settings › Account › Delete account deletes your account and everything stored with it right away. Server logs expire within 30 days and Azure's automatic database backups within a day. Deleting the app alone does not delete your account.

Your rights

You can ask for a copy of your data, have it corrected or deleted, take it elsewhere, or withdraw your consent (which means deleting the account, since the app depends on it). Write to the address above. You can also complain to Serbia's Commissioner for Information of Public Importance and Personal Data Protection (poverenik.rs) or to the data protection authority where you live.

Children

Fitt is not meant for anyone under 16.

Changes

If this policy changes, the new version is posted here with a new date.
