Privacy policy

Effective 9 October 2026.

Tuko is a tennis fitness coach that runs entirely on your phone. It does not collect, sell or share any personal data.

No account, no tracking. Tuko has no sign-up, no analytics, no advertising and no tracking of any kind. It does not connect to the internet.

What stays on your phone. Your settings and training progress are saved on your device only. Deleting the app deletes them.

Calendar (optional). If you turn on "Put training in my calendar", Tuko asks for calendar access. It uses it only to add your upcoming training sessions, keep them up to date and remove them when you turn the feature off. It looks through your calendars only to find its own events, changes only the events it created, and never stores or sends anything from your calendar. Your calendar provider (for example Google or iCloud) syncs these events like any other.

Notifications (optional). Coach reminders are scheduled on your phone. Nothing is sent to a server.

Children. Tuko is not directed at children under 13.

Changes. If this policy changes, the new version will be posted here with a new effective date.
