Commercial Electronic Message Consent Form

This is an English translation. In case of any conflict, the Turkish version prevails.

Last updated: October 31, 2026

Version: 1.0

This form was prepared under Article 6 of Law No. 6563 on the Regulation of Electronic Commerce (Elektronik Ticaretin Düzenlenmesi Hakkında Kanun) and Article 5(1) of Personal Data Protection Law No. 6698 (Kişisel Verilerin Korunması Kanunu) to ask for your consent to promotional messages. Giving consent is optional. Even if you don't, you can use all of BlueGrays' features and make purchases exactly the same way.

What are you consenting to?

If you tick the consent box, Yunus Emre EKE (BlueGrays, [email protected]) may send you promotional messages through these channels:

  • Email: to the email address in your BlueGrays account,
  • Push notifications: to your devices that have the BlueGrays app installed.

What the messages are about:

  • Premium campaigns,
  • Discount offers just for you and reminders before these offers end,
  • Announcements of new features, content and events.

Messages sent regardless of consent

The following aren't promotional; they're part of the service. They're sent even if you don't give consent. These messages don't promote any product or campaign.

  • Account verification, password reset and security notifications,
  • Purchase and subscription status notifications,
  • Replies to your support requests, educator code notifications,
  • Badges you've earned,
  • If you turned them on, Daily Questions reminders and weekly league results (you can turn these off in Daily Questions settings),
  • Legal notices, such as changes to agreements.

Data processed

Your first name, last name, email address, your device's notification address and your consent record are processed. The consent record includes the date of consent, the channel, where it was given and the version of this form. Emails are sent with Twilio SendGrid (US), and push notifications with Google Firebase Cloud Messaging (US). You'll find the details in the KVKK Privacy Notice.

How can you withdraw your consent?

You can withdraw your consent at any time, without giving a reason and free of charge:

  • In the app, by turning off the "Campaigns and discounts" switch under Profile > Preferences > Notifications,
  • With the one-click "Unsubscribe" link at the bottom of promotional emails,
  • By writing to [email protected].

We stop sending promotional messages within 3 business days at the latest after your opt-out request reaches us. We keep consent records for 3 years after consent is withdrawn.
