You can do the following yourself — most questions are answered here.
Subscriptions are managed by Apple; Kelan cannot cancel one on your behalf. On your iPhone, go to Settings ▸ Apple Account ▸ Subscriptions ▸ Kelan. After cancelling you keep access until the end of the current period.
Refunds are handled by Apple. You can request one at reportaproblem.apple.com.
If you reinstalled the app or moved to a new device, use the "Restore Purchases" button on the paywall. You must be signed in with the same Apple Account you used to subscribe.
The trial is counted in bookings, not days: the first 10 bookings are free. Once you reach the limit the app opens the paywall.
In the app, go to Settings ▸ Delete Account. This permanently removes your account, your appointments and your booking page; it cannot be undone. If you have an active subscription, cancel it separately through Apple (see above).
Use the manage-appointment link in your confirmation e-mail — cancellation happens there. If you cannot find the link, contact the provider you booked with directly; Kelan cannot cancel an appointment on their behalf.
Your page is published at kelan.me/yourusername. Make sure you have set your username in the app and saved your working hours, then keep the app open until the sync finishes.
Send any request regarding your personal data (access, rectification, erasure, objection) to destek@kelan.me. Requests are concluded free of charge within 30 days at the latest. See the Privacy Notice (KVKK) for details.
Including these helps us answer faster: your username, device model, iOS version and a screenshot of the problem.
