Personal Data Requests

Effective date: October 22, 2026 · Last updated: October 22, 2026

This page explains how to exercise your rights under KVKK Art. 11 and, if they apply to you, the EU General Data Protection Regulation (GDPR) or the UK GDPR. Data controller: Hasan Can Demircan, support@sestinaapp.com.

1. Your rights

KVKK Art. 11: to learn whether your data is processed, request information, learn the purpose, know the third parties it is transferred to, correction, deletion or destruction, notification of these to third parties, objection to an automated analysis outcome, and compensation. Details: Privacy Notice.
GDPR / UK GDPR: access, rectification, erasure, restriction of processing, objection, data portability, and withdrawing consent at any time.

2. What you can do right away in the App

Right	How in the App?
Access and data portability	Profile → Download my data: your profile, style profile, wardrobe details, outfits, favorites, consent history and subscription status are prepared as a machine-readable file (JSON) and saved through the share menu. The file contains download links for your photos, valid for 1 hour. Can be used up to 3 times a day.
Rectification	You can edit your name, physical profile and the details of your wardrobe items on the Profile and Wardrobe screens.
Erasure	You can delete clothing items from your wardrobe and your profile photo via Profile → My photo; you can delete your account and all your data via Profile → Delete My Account (see Delete Your Account).
Withdrawing consent / permission	Profile → Privacy & permissions: the AI permission and the virtual try-on consents, each separately (see Consent and Permission Texts).

3. How to apply

You apply by email to support@sestinaapp.com from an email address previously notified to the data controller and registered in the data controller’s system (the email address registered to your Sestina account) (Communiqué on the Procedures and Principles of Application to the Data Controller, Art. 5). If you write from another address, your application is processed after it has been verified through your registered address (section 4). Putting “KVKK Application” (or “Data Request” if the GDPR / UK GDPR applies to you) in the subject line helps us identify your request quickly.

Your application must include:

Your first and last name,
If you are a citizen of the Republic of Turkey, your Turkish ID number; if you are a foreign national, your nationality and passport number or, if any, your ID number,
Your residential or business address for notifications,
If any, your email address and telephone number for notifications,
The subject of your request: the right you want to exercise and a description of your request.

You may attach information and documents related to your request.

4. Identity verification

If your application comes from the address registered in our system, your identity is verified through that address. If your application comes from another address, we send a verification code to the address registered to your account; your application is processed once the code is answered from that address. Until verification is complete we do not share data or delete anything.

If you signed up with Apple’s “Hide My Email”, the address registered in our system is the relay address Apple gave you. The verification code is sent to that address and forwarded to you by Apple; when you reply, your reply reaches us from the relay address and your application is processed.

5. Timing and cost

We respond to your request within 30 days at the latest, free of charge. If we do not accept your request, we will tell you the reasons in writing.

6. Right to complain

Turkey: if your request is rejected, you find the answer insufficient, or no answer is given in time, you can complain to the Personal Data Protection Board within 30 days of learning the answer and in any case within 60 days of your application.
United Kingdom: you can complain to the Information Commissioner’s Office (ICO).
EU / EEA: you can complain to the data protection authority in your country.
