Privacy policy

Strife Privacy Policy

Strife is a mobile application for managing gyms and martial-arts centers. This policy describes which personal data we process, for what purpose, and which rights you have. Last updated: August 23, 2026.

Data controller

The data controller is Jaime Villalba Gil. For any matter regarding your data you can write to jaimevillalbagil@gmail.com.

What data we collect and where it comes from

We only process the data needed for the application to work. Each category is collected in the context indicated:

Email, name and profile photo Sign-up and sign-in (Google Sign-In or email and password) and profile editing.
Microphone Recording voice notes in the center chat, only while you are recording.
Photos and files Attachments you send in the center chat and in admission requests, and profile or center photos you upload.
Approximate and precise location Nearby gym search, only when you open it and ask for it. Used at that moment and then discarded; it is not saved in our database.
Health and fitness data: weight Voluntary weight logging (scale) within your center. This is sensitive-category data and is only processed if you enter it.
Messages Messages and voice notes in the chat of the center you belong to.
Attendance and sports activity Class bookings, attendance records, sparring rounds and achievements within your center.
External profiles Links to your Smoothcomp or Instagram profiles, if you choose to link them.

Location

The application requests your approximate and precise location only when you open the nearby gym search and expressly ask for it. There is no background collection and no continuous tracking. The location is used at that moment to sort gyms by proximity and is discarded afterwards: it is not stored in our database. To resolve the search, the location leaves the device towards Google Maps and Google Places, subject to Google's privacy policy.

Explicit notice on health data

Weight logging constitutes health-related data. It is processed solely on the basis of your explicit consent, expressed by voluntarily entering it in the application, and you can stop logging it or request its erasure at any time.

Who processes the data

Data is stored in Supabase (database, authentication and file storage), hosted on Amazon Web Services infrastructure in the eu-central-1 region (Frankfurt, Germany, European Union). In addition, Google sign-in and gym search on the map use Google services (Google Sign-In, Google Maps and Places), subject to Google's privacy policy.

Legal basis

We process your data on the following bases: the performance of the service you request when creating your account and participating in a center (identity, messages, bookings, attendance); your consent for optional data (microphone, weight, external profiles), which you can withdraw at any time; and the legitimate interest of the sports center in keeping its operational history (attendance and payments).

Retention periods

Your data is kept while your account is active. When you request account deletion, your identity is erased as described on the account deletion page; the center's operational history (attendance, bookings and payments) is kept in anonymized form based on the center's legitimate interest and possible legal obligations.

Your rights

Under the GDPR you may exercise at any time your rights of access, rectification, erasure and portability, as well as restriction of or objection to processing, by writing to jaimevillalbagil@gmail.com. You also have the right to lodge a complaint with the competent supervisory authority (in Spain, the AEPD).

Minors

Strife is aimed at people who can have their own account, that is, from the age of 13; below that age no accounts are created. Children in the kids' classes (the 4-8 and 9-11 groups) are enrolled by their father, mother or legal guardian, or by the center itself: they have no account and do not use the application. The data of an enrolled minor is processed on behalf of whoever enrolls them —the parent or guardian, or the center—, who is responsible for having the necessary legal basis and consent. To exercise the minor's rights (access, rectification, erasure, restriction, objection and portability), their parent or guardian, or the center that enrolled them, can write to jaimevillalbagil@gmail.com.
