Privacy policy
Last updated: 19 October 2026
This policy explains how the Yalla Sinai app and website handle your data. In short: neither has accounts, forms or sign-in, there are no ads, analytics or tracking, and the only data the app handles is a notification identifier, if you allow notifications.
Who we are
Supportefy, LLC runs the Yalla Sinai app and website and is responsible for the data described in this policy (the data controller). You can reach us on WhatsApp at +20 100 420 7202 or by email at info@supportefy.com.
The app
The Yalla Sinai app has no accounts, no sign-in, no ads, no analytics, no advertising ID and no tracking, and it never asks for your name, phone number or email. Apart from permission to show notifications, it asks for no permissions on your device, such as location, camera or contacts.
Notifications
If you allow notifications, the app registers with Firebase Cloud Messaging, a Google service that gives your app installation an identifier (a Firebase installation ID and push token). It is used only to deliver notifications. The app also subscribes it to broadcast topics (all users, your app language and your phone's platform) so our team can send announcements to everyone. No name, phone number or email is linked to it, and we never sell it or use it for advertising. Firebase Cloud Messaging is run by Google under Google's privacy policy (https://policies.google.com/privacy), and this data may be processed outside Egypt. You can switch notifications off at any time in your phone's settings, and the app will offer its own switch later.
Settings on your phone
The app saves three settings on your phone only: your language, light or dark theme, and whether you have seen the welcome screen. They are never sent to us. If you use Android backup, they may be included in your own device backup. Clearing the app's data removes them.
The website
The website has no accounts or forms, uses no cookies, analytics, ads or trackers, and loads no fonts or scripts from other companies. If you pick a language, your browser remembers it in its local storage so the page opens in your language next time. It stays on your device and is never sent to us.
Server logs
Like every website, ours is run by a hosting provider that keeps standard server logs of each page request: IP address, time and the page requested. They are used only to keep the site secure and working, are kept for a limited time and are never used to build profiles.
WhatsApp and Telegram
The buttons for listing your business and contacting us open WhatsApp, and some links may open Telegram. Those apps work under their own privacy policies. If you send us a message there, it reaches the Yalla Sinai team's number with your phone number or username, and we use it only to answer you. We never sell it or use it for advertising, and we delete the conversation if you ask.
Children
The Yalla Sinai app is made for adults and is not directed at children under 13.
Your choices
You can ask us at any time what we hold about you, such as a WhatsApp conversation, or ask us to delete it, on WhatsApp or by email at info@supportefy.com.
Changes to this policy
If the app adds features that need personal data, such as accounts, bookings or payments, we will update this policy before those features go live, and the app will show you the change. The date at the top shows the latest version.
